• How can I transfer a SQL Server 2005 license?

  - by jdk

  I have the a wrong license number in one SQL Server. What's gone down is this: We virtualized a physical server, effectively cloning its software and licenses - SQL Server included. We want to repurpose the physical machine by keeping SQL Server and modifying its license to another license key that we have purchased. Would prefer not to reinstall SQL Server. Can it be done?

• ASP.NET MVC 2: Updating a Linq-To-Sql Entity with an EntitySet

  - by Simon

  I have a Linq to Sql Entity which has an EntitySet. In my View I display the Entity with it's properties plus an editable list for the child entites. The user can dynamically add and delete those child entities. The DefaultModelBinder works fine so far, it correctly binds the child entites. Now my problem is that I just can't get Linq To Sql to delete the deleted child entities, it will happily add new ones but not delete the deleted ones. I have enabled cascade deleting in the foreign key relationship, and the Linq To Sql designer added the "DeleteOnNull=true" attribute to the foreign key relationships. If I manually delete a child entity like this: myObject.Childs.Remove(child); context.SubmitChanges(); This will delete the child record from the DB. But I can't get it to work for a model binded object. I tried the following: // this does nothing public ActionResult Update(int id, MyObject obj) // obj now has 4 child entities { var obj2 = _repository.GetObj(id); // obj2 has 6 child entities if(TryUpdateModel(obj2)) //it sucessfully updates obj2 and its childs { _repository.SubmitChanges(); // nothing happens, records stay in DB } else ..... return RedirectToAction("List"); } and this throws an InvalidOperationException, I have a german OS so I'm not exactly sure what the error message is in english, but it says something along the lines of that the entity needs a Version (Timestamp row?) or no update check policies. I have set UpdateCheck="Never" to every column except the primary key column. public ActionResult Update(MyObject obj) { _repository.MyObjectTable.Attach(obj, true); _repository.SubmitChanges(); // never gets here, exception at attach } I've read alot about similar "problems" with Linq To Sql, but it seems most of those "problems" are actually by design. So am I right in my assumption that this doesn't work like I expect it to work? Do I really have to manually iterate through the child entities and delete, update and insert them manually? For such a simple object this may work, but I plan to create more complex objects with nested EntitySets and so on. This is just a test to see what works and what not. So far I'm disappointed with Linq To Sql (maybe I just don't get it). Would be the Entity Framework or NHibernate a better choice for this scenario? Or would I run into the same problem?

• Why are there connections open to my databases?

  - by Everett

  I have a program that stores user projects as databases. Naturally, the program should allow the user to create and delete the databases as they need to. When the program boots up, it looks for all the databases in a specific SQLServer instance that have the structure the program is expecting. These database are then loaded into a listbox so the user can pick one to open as a project to work on. When I try to delete a database from the program, I always get an SQL error saying that the database is currently open and the operation fails. I've determined that the code that checks for the databases to load is causing the problem. I'm not sure why though, because I'm quite sure that all the connections are being properly closed. Here are all the relevant functions. After calling BuildProjectList, running "DROP DATABASE database_name" from ExecuteSQL fails with the message: "Cannot drop database because it is currently in use". I'm using SQLServer 2005. private SqlConnection databaseConnection; private string connectionString; private ArrayList databases; public ArrayList BuildProjectList() { //databases is an ArrayList of all the databases in an instance if (databases.Count <= 0) { return null; } ArrayList databaseNames = new ArrayList(); for (int i = 0; i < databases.Count; i++) { string db = databases[i].ToString(); connectionString = "Server=localhost\\SQLExpress;Trusted_Connection=True;Database=" + db + ";"; //Check if the database has the table required for the project string sql = "select * from TableExpectedToExist"; if (ExecuteSQL(sql)) { databaseNames.Add(db); } } return databaseNames; } private bool ExecuteSQL(string sql) { bool success = false; openConnection(); SqlCommand cmd = new SqlCommand(sql, databaseConnection); try { cmd.ExecuteNonQuery(); success = true; } catch (SqlException ae) { MessageBox.Show(ae.Message.ToString()); } closeConnection(); return success; } public void openConnection() { databaseConnection = new SqlConnection(connectionString); try { databaseConnection.Open(); } catch(Exception e) { MessageBox.Show(e.ToString(), "Error", MessageBoxButtons.OK, MessageBoxIcon.Error); } } public void closeConnection() { if (databaseConnection != null) { try { databaseConnection.Close(); } catch (Exception e) { MessageBox.Show(e.ToString(), "Error", MessageBoxButtons.OK, MessageBoxIcon.Error); } } }

• The question about the basics of LINQ to SQL

  - by Alex

  I just started learning LINQ to SQL, and so far I'm impressed with the easy of use and good performance. I used to think that when doing LINQ queries like from Customer in DB.Customers where Customer.Age > 30 select Customer LINQ gets all customers from the database ("SELECT * FROM Customers"), moves them to the Customers array and then makes a search in that Array using .NET methods. This is very inefficient, what if there are hundreds of thousands of customers in the database? Making such big SELECT queries would kill the web application. Now after experiencing how actually fast LINQ to SQL is, I start to suspect that when doing that query I just wrote, LINQ somehow converts it to a SQL Query string SELECT * FROM Customers WHERE Age > 30 And only when necessary it will run the query. So my question is: am I right? And when is the query actually run? The reason why I'm asking is not only because I want to understand how it works in order to build good optimized applications, but because I came across the following problem. I have 2 tables, one of them is Books, the other has information on how many books were sold on certain days. My goal is to select books that had at least 50 sales/day in past 10 days. It's done with this simple query: from Book in DB.Books where (from Sale in DB.Sales where Sale.SalesAmount >= 50 && Sale.DateOfSale >= DateTime.Now.AddDays(-10) select Sale.BookID).Contains(Book.ID) select Book The point is, I have to use the checking part in several queries and I decided to create an array with IDs of all popular books: var popularBooksIDs = from Sale in DB.Sales where Sale.SalesAmount >= 50 && Sale.DateOfSale >= DateTime.Now.AddDays(-10) select Sale.BookID; BUT when I try to do the query now: from Book in DB.Books where popularBooksIDs.Contains(Book.ID) select Book It doesn't work! That's why I think that we can't use thins kinds of shortcuts in LINQ to SQL queries, like we can't use them in real SQL. We have to create straightforward queries, am I right?

• Multiple Connection Types for one Designer Generated TableAdapter

  - by Tim

  I have a Windows Forms application with a DataSet (.xsd) that is currently set to connect to a Sql Ce database. Compact Edition is being used so the users can use this application in the field without an internet connection, and then sync their data at day's end. I have been given a new project to create a supplemental web interface for displaying some of the same reports as the Windows Forms application so certain users can obtain reports without installing the Windows app. What I've done so far is create a new Web Project and added it to my current Solution. I have split both the reports (.rdlc) and DataSets out of the Windows Forms project into their own projects so they can be accessed by both the Windows and Web applications. So far, this is working fine. Here's my dilemma: As I said before, the DataSets are currently set up to connect to a local Sql Ce database file. This is correct for the Windows app, but for the Web application I would like to use these same TableAdapters and queries to connect to the Sql Server 2005 database. I have found that the designer generated, strongly-typed TableAdapter classes have a ConnectionModifier property that allows you to make the TableAdapter's Connection public. This exposes the Connection property and allows me to set it, however it is strongly-typed as a SqlCeConnection, whereas I would like to set it to a SqlConnection for my Web project. I'm assuming the DataSet Designer strongly-types the Connection, Command, and DataAdapter objects based on the Provider of the ConnectionString as indicated in the app.config file. Is there any way I can use some generic provider so that the DataSet Designer will use object types that can connect to both a Sql Ce database file AND the actual Sql Server 2005 database? I know that SqlCeConnection and SqlConnection both inherit from DbConnection, which implements IDbConnection. Relatively, the same goes for SqlCeCommand/SqlCommand:DbCommand:IDbCommand. It would be nice if I could just figure out a way for the designer to use the Interface types rather than the strong types, but I'm hesitant that that is possible. I hope my problem and question are clear. Any help is much appreciated. Let me know if there's anything I can clarify.

• SQL/Schema comparison and upgrade

  - by Workshop Alex

  I have a simple situation. A large organisation is using several different versions of some (desktop) application and each version has it's own database structure. There are about 200 offices and each office will have it's own version, which can be one of 7 different ones. The company wants to upgrade all applications to the latest versions, which will be version 8. The problem is that they don't have a separate database for each version. Nor do they have a separate database for each office. They have one single database which is handled by a dedicated server, thus keeping things like management and backups easier. Every office has it's own database schema and within the schema there's the whole database structure for their specific application version. As a result, I'm dealing with 200 different schema's which need to be upgraded, each with 7 possible versions. Fortunately, every schema knows the proper version so checking the version isn't difficult. But my problem is that I need to create upgrade scripts which can upgrade from version 1 to version 2 to version 3 to etc... Basically, all schema's need to be bumped up one version until they're all version 8. Writing the code that will do this is no problem. the challenge is how to create the upgrade script from one version to the other? Preferably with some automated tool. I've examined RedGate's SQL Compare and Altova's DatabaseSpy but they're not practical. Altova is way too slow. RedGate requires too much processing afterwards, since the generated SQL Script still has a few errors and it refers to the schema name. Furthermore, the code needs to become part of a stored procedure and the code generated by RedGate doesn't really fit inside a single procedure. (Plus, it's doing too much transaction-handling, while I need everything within a single transaction. I have been considering using another SQL Comparison tool but it seems to me that my case is just too different from what standard tools can deliver. So I'm going to write my own comparison tool. To do this, I'll be using ADOX with Delphi to read the catalogues for every schema version in the database, then use this to write the SQL Statements that will need to upgrade these schema's to their next version. (Comparing 1 with 2, 2 with 3, 3 with 4, etc.) I'm not unfamiliar with generating SQL-Script-Generators so I don't expect too many problems. And I'll only be upgrading the table structures, not any of the other database objects. So, does anyone have some good tips and tricks to apply when doing this kind of comparisons? Things to be aware of? Practical tips to increase speed?

• Support material - UG Presentation "Using Indexed Views and Computed Columns for Performance"

  - by NeilHambly

  London SQL Server UG Presentation, @ Microsoft Victoria (17 th March 2010). As this was my First UG Presentation I picked a topic and dutifully researched and prepared the PowerPoint Slides & a brief introduction, @ the last minute we needed to change the order of presentations due to small technical hitch with one of the laptops for the first presentation. So having an earlier appearance, meant I conveniently forgot what I had planned (funny that!), so It was a more thinking-on-your-feet kind...(read more)

• SQL Triggers and when or when not to use them.

  - by John Mitchell

  When I was originally learning about SQL I was always told, only use triggers if you really need to and opt to use stored procedures instead if possible. Now unfortunately at the time (a good few years ago) I wasn't as curious and caring about fundamentals as I am now so never did ask to the reason why. What's the communities opinion in this? Is it just someone's personal preference, or should triggers be avoided (just like cursors) unless there is a good reason for them.

• SQL Monitor Performance Metric: Buffer Cache Used Per Database in MB

  Data pages read from disk are placed in the buffer pool with the intention that they will be reused, and accessing them from RAM is faster than from disk. Knowing how much of your RAM is committed to each database can help you provision the right amount of RAM to SQL Server, and also to identify rogue queries that draw too much data into RAM and force data from other databases out of the cache. Deployment Manager 2 is now free!The new version includes tons of new features and we've launched a completely free Starter Edition! Get Deployment Manager here

• Is there a recommended approach for using SQL Server as an Authorization store and extending AD properties using .Net? [closed]

  - by Jim

  We are going to be using SQL Server as an authorization store for our .Net windows services and WCF services as well as storing additional metadata about users and groups to extend the AD properties. Doing this will make this self service and not require IT to change anything for our department (for users or groups). What if any are the existing recommended stategies or technologies that do this function?

• ClearTrace Performance on 170GB of Trace Files

  - by Bill Graziano

  I’ve always worked to make ClearTrace perform well.  That’s probably because I spend so much time watching it work.  I’m often going through two or three gigabytes of trace files but I rarely get the chance to run it on a really large set of files. One of my clients wanted to run a full trace for a week and then analyze the results.  At the end of that week we had 847 200MB trace files for a total of nearly 170GB. I regularly use 200MB trace files when I monitor production systems.  I usually get around 300,000 statements in a file that size if it’s mostly stored procedures.  So those 847 trace files contained roughly 250 million statements.  (That’s 730 bytes per statement if you’re keeping track.  Newer trace files have some compression in them but I’m not exactly sure what they’re doing.)  On a system running 1,000 statements per second I get a new file every five minutes or so. It took 27 hours to process these files on an older development box.  That works out to 1.77MB/second.  That means ClearTrace processed about 2,654 statements per second. You can query the data while you’re loading it but I’ve found it works better to use a second instance of ClearTrace to do this.  I’m not sure why yet but I think there’s still some dependency between the two processes. ClearTrace is almost always CPU bound.  It’s really just a huge, ugly collection of regular expressions.  It only writes a summary to its database at the end of each trace file so that usually isn’t a bottleneck.  At the end of this process, the executable was using roughly 435MB of RAM.  Certainly more than when it started but I think that’s acceptable. The database where all this is stored started out at 100MB.  After processing 170GB of trace files the database had grown to 203MB.  The space savings are due to the “datawarehouse-ish” design and only storing a summary of each trace file. You can download ClearTrace for SQL Server 2008 or test out the beta version for SQL Server 2012.  Happy Tuning!

• How to Link VS2010 Database Project and LINQ to SQL

  - by Jason

  As I am working with the new database projects in VS2010, and as I am learning LINQ to SQL, I am curious as to the best way to link the two groups of information so that when I update one, the other updates along with it. From my research here at SO, as well as in Google, it appears the general rule of thumb is: "Build the database, and then create your LINQ to SQL classes." Of course, if I make a change in my database, the LINQ to SQL doesn't update automatically and I have to do it by hand. This is fairly simple right now as my database is small, but I am curious if there is an easier way for this to happen. In addition, the LINQ to SQL tool is pretty nice. The ability to create tables, add associations, and even create inheritance is very simple. As my second question, I am curious as to whether or not VS2010 can work the other way - I design the database in the DBLM file and then link it back to my database project. I appreciate any help with either of these two questions. I'm really interested in making this as easy as possible to reduce errors during development and improve the speed at which changes can be made.

• SQL Server Management Studio – tips for improving the TSQL coding process

  - by kristof

  I used to work in a place where a common practice was to use Pair Programming. I remember how many small things we could learn from each other when working together on the code. Picking up new shortcuts, code snippets etc. with time significantly improved our efficiency of writing code. Since I started working with SQL Server I have been left on my own. The best habits I would normally pick from working together with other people which I cannot do now. So here is the question: What are you tips on efficiently writing TSQL code using SQL Server Management Studio? Please keep the tips to 2 – 3 things/shortcuts that you think improve you speed of coding Please stay within the scope of TSQL and SQL Server Management Studio 2005/2008 If the feature is specific to the version of Management Studio please indicate: e.g. “Works with SQL Server 2008 only" Thanks EDIT: I am afraid that I could have been misunderstood by some of you. I am not looking for tips for writing efficient TSQL code but rather for advice on how to efficiently use Management Studio to speed up the coding process itself. The type of answers that I am looking for are: use of templates, keyboard-shortcuts, use of IntelliSense plugins etc. Basically those little things that make the coding experience a bit more efficient and pleasant. Thanks again

• Cannot connect to a SQL Server 2005 Analysis Services cube after installing SQL Server 2008 SP1.

  - by Luc

  I've been developing an application that talks directly to an SSAS 2005 OLAP cube. Note that I also have SQL Server 2008 installed, so the other day I did a Windows Update and decided to include SQL Server 2008 SP1 in my update. After doing that, my SSAS 2005 cube is no longer accessible from my application. I'm able to browse the data just fine within SQL Server 2005 BI Studio Manager, but I'm not able to connect to the cube from my application. Here is my connection string that used to work: Data Source=localhost;Provider=msolap;Initial Catalog=Adventure Works DW Here is the error message I get: Either the user, [Server]/[User], does not have access to the Adventure Works DW database, or the database does not exist.

• Slow query with unexpected index scan

  - by zerkms

  Hello I have this query: SELECT * FROM sample INNER JOIN test ON sample.sample_number = test.sample_number INNER JOIN result ON test.test_number = result.test_number WHERE sampled_date BETWEEN '2010-03-17 09:00' AND '2010-03-17 12:00' the biggest table here is RESULT, contains 11.1M records. The left 2 tables about 1M. this query works slowly (more than 10 minutes) and returns about 800 records. executing plan shows clustered index scan (over it's PRIMARY KEY (result.result_number, which actually doesn't take part in query)) over all 11M records. RESULT.TEST_NUMBER is a clustered primary key. if I change 2010-03-17 09:00 to 2010-03-17 10:00 - i get about 40 records. it executes for 300ms. and plan shows index seek (over result.test_number index) if i replace * in SELECT clause to result.test_number (covered with index) - then all become fast in first case too. this points to hdd IO issues, but doesn't clarifies changing plan. so, any ideas? UPDATE: sampled_date is in table sample and covered by index. other fields from this query: test.sample_number is covered by index and result.test_number too. UPDATE 2: obviously than sql server in any reasons don't want to use index. i did a small experiment: i remove INNER JOIN with result, select all test.test_number and after that do SELECT * FROM RESULT WHERE TEST_NUMBER IN (...) this, of course, works fast. but i cannot get what is the difference and why query optimizer choose such inappropriate way to select data in 1st case.

• Issues Connecting to SQLExpress using Oracle SQL Developer

  - by ArtDeveloper

  Hey Guys, I'm trying to create a connection inside Oracle SQL Developer to a SQLExpress database I have Everything I have resides on the same machine so there isn't any network issues I should have to deal with but everytime I follow the instructions and I try to connect I get the following message "Failure - Unable to get information from SQL Server: localhost." I can connect to the SQLExpress DB using the SQL Management Studio and through an ODBC connection. I've installed the third party extensions and I've enabled the TCP protocol on the SQL Server Configuration manager as well as enabled the IP Addresses I'm assuming that the SQLExpress Database is on port 1433 because I didn't change this when I installed but if someone can tell me how to double check that I would appreciate that info as well. I setup the new connection with the following information name: databasename I'm using windows authentication so the username and password aren't filled in host:localhost port:1433/databasename;instance=SQLEXPRESS *databasename - this is replaced with the actual DB name I've just changed the name here to protect the innocent I've spent about a full day on this trying to get it connected and many google attempts where other ppl have had this issue but have gotten it solved through various methods that I've tried and it hasn't resolved my issue. Any information would be much appreciated Thank you in Advance, AD

• Display a Photo Gallery using Asp.Net and SQL

  - by sweetcoder

  I have recently added photos to my SQL database and have displayed them on an *.aspx page using Asp:Image. The ImageUrl for this control stored in a separate *.aspx page. It works great for profile pictures. I have a new issue at hand. I need each user to be able to have their own photo gallery page. I want the photos to be stored in the sql database. Storing the photos is not difficult. The issue is displaying the photos. I want the photos to be stored in a thumbnail grid fashion, when the user clicks on the photo, it should bring up the photo on a separate page. What is the best way to do this. Obviously it is not to use Asp:Image. I am curious if I should use a Gridview. If so, how do I do that and should their be a thumbnail size stored in the database for this? Once the picture is click on how does the other page look so that it displays the correct image. I would think it is not correct to send the photoId through the url. Below is code from the page I use to display profile pictures. protected void Page_Load(object sender, EventArgs e) { string sql = "SELECT [ProfileImage] FROM [UserProfile] WHERE [UserId] = '" + User.Identity.Name.ToString() + "'"; string strCon = System.Web.Configuration.WebConfigurationManager.ConnectionStrings["SocialSiteConnectionString"].ConnectionString; SqlConnection conn = new SqlConnection(strCon); SqlCommand comm = new SqlCommand(sql, conn); conn.Open(); Response.ContentType = "image/jpeg"; Response.BinaryWrite((byte[])comm.ExecuteScalar()); conn.Close(); }

• WCF fault logging and SQL Exception 4060 error.

  - by Bill

  I have been attempting to compile/run a sample WCF application from Juval Lowy's website (author of Programming WCF Services & founder of IDesign) for several days. The example app utilizes Juval's ServiceModelEx library which logs faults/errors to a "WCFLogbook" SQL database. Unfortunately, when the sample app faults, I get the following error: SQL Exception 4060: "Cannot open database \"WCFLogbook\" requested by the login. The login failed.\r\nLogin failed for user 'Bill-PC\Bill'." I confirmed that the SQL WCFLogbook database has been created and have granted all of the appropriate permissions for my (Bill-PC\Bill) access to the database. Additionally port 8006 and port 1433 have been opened in the Firewall. TCP/IP has been enabled and "Allow remote connections to this server" has been checked. I am using the following endpoint within the App.Config file: <client> <endpoint name="LogbookTCP" address="net.tcp://Bill-PC:8006/LogbookManager" binding="netTcpBinding" contract="ILogbookManager" /> </client> Unfortunately SQL is a 'world' that I hadn't needed to venture into before now and I am terribly frustrated with my lack of success. Would anyone have any other suggestions on how to get this working? Have I missed anything?

• Can't connect to SQL Server 2008 - looks like Shared Memory problem

  - by Proposition Joe

  I am unable to connect to my local instance of SQL Server 2008 Express using SQL Server Management Studio. I believe the problem is related to a change I made to the connection protocols. Before the error occurred, I had Shared Memory enabled and Named Pipes and TCP/IP disabled. I then enabled both Named Pipes and TCP/IP, and this is when I started experiencing the problem. When I try to connect to the server with SSMS (with either my SQL server sysadmin login or with windows authentication), I get the following error message: A connection was successfully established with the server, but then an error occurred during the login process. (provider: Named Pipes Provider, error: 0 - No process is on the other end of the pipe.) (Microsoft SQL Server, Error: 233) Why is it returning a Named Pipes error? Why would it not just use Shared Memory, as this has a higher priority order in the list of connection protocols? It seems like it is not listening on Shared Memory for some reason? When I set Named Pipes to enabled and try to connect, I get the same error message. My windows account is does not have administrator priviliges on my computer - perhaps this is making a difference in some way (as some of the discussions in this post about an "SuperSocketNetLib\Lpc" registry key seems to suggest).

• Package creation issues using SQL Developer

  - by Carter

  So I've never worked with stored procedures and have not a whole lot of DB experience in general and I've been assigned a task that requires I create a package and I'm stuck. Using SQL Developer, I'm trying to create a package called JUMPTO with this code... create or replace package JUMPTO is type t_locations is ref cursor; procedure procGetLocations(locations out t_locations); end JUMPTO; When I run it, it spits out this PL/SQL code block... DECLARE LOCATIONS APPLICATION.JUMPTO.t_locations; BEGIN JUMPTO.PROCGET_LOCATIONS( LOCATIONS = LOCATIONS ); -- Modify the code to output the variable -- DBMS_OUTPUT.PUT_LINE('LOCATIONS = ' || LOCATIONS); END; A tutorial I found said to take out the comment for that second line there. I've tried with and without the comment. When I hit "ok" I get the error... ORA-06550: line 2, column 32: PLS-00302: component 'JUMPTO' must be declared ORA-06550: line 2, column 13: PL/SQL: item ignored ORA-06550: line 6, column 18: PLS-00320: the declaration of the type of this expression is incomplete or malformed ORA-06550: line 5, column 3: PL/SQL: Statement ignored ORA-06512: at line 58 I really don't have any idea what's going on, this is all completely new territory for me. I tried creating a body that just selected some stuff from the database but nothing is working the way it seems like it should in my head. Can anyone give me any insight into this?

• Replacing XML reserved characters in SQL Server 2005

  - by Barn

  I'm working on a system that takes relational data from a sql server DB and uses SSIS to produce an XML extract using sql server 2005's 'FOR XML PATH' command and a schema. The problem lies with replacing the XML reserved characters. 'FOR XML PATH' is only replacing <, , and &, not ' and ", so I need a way of replacing these myself. I've tried pre-processing the fields in the database to replace XML reserved characters with their entitised equivalents (e.g. & becomes &amp;), but once these fields are used to construct XML using FOR XML the leading & is replaced with &amp;, so I end up with &amp;amp; where I should have &amp;. What I've tried so far is altering the element's contents after the XML has been constructed using XQuery inside SQL server like so: DECLARE @data VARCHAR(MAX) SET @data = CONVERT(VARCHAR(MAX), [my xml column].query(' data(/root/node_i_want)') SELECT @data = [function to replace quotes etc](@data) SET [my xml column].modify('replace value of (/root/node_i_want)[1] with sql:variable("@data")') but I get the same problem. Essentially, is there something wrong I'm doing with the above, or a way to tell FOR XML to entitise other characters, or something like that? Basically anything short of having to write a program to change the XML after it has been assembled in large batches and saved to files!

• Python: How to execute a SQL file or command

  - by Mestika

  Hi, I have this Python script: import sys import getopt import timeit import random import os import re import ibm_db import time from string import maketrans runs=5 queries=50 file = open("results.txt", "a") for r in range(5): print "Run %s\n" % r os.system("python reads.py -r1 -pquery1.sql -q50 -sespec") file.write('END QUERY READ 01') file.close() os.system("python query_read_02.py") Everything here is working, it is creating the results.txt file, it run the os.system("python reads.py...") file and that file is doing everything it's suppose to, but the problem comes when go and run the query_read_02.py file. In this file, it should execute a SQL command or a SQL file on my database, so I can create an index and see what the performance of that input is, but how do i do it? I create the connection to the database in the reads.py file, but it's hard to create the queries in there because I doesn't keep track of which file it has reached, it just execute commands from what the parameters are. I hope I've explained myself clear enough, otherwise please let me know. I just want to execute a SQL command or file which each query_read_0x.py file. Sincerely Mestika
