  • Transferring a flat file database to a MySQL database

    - by Jon
    I have a flat file database (yeah gross I know - the worst part is that it's 1.4GB), and I'm in the process of moving it to a MySQL database. The problem is that I'm not sure how to go about doing this - and I've checked through every related question on here but none relate to what I want to do, nor how my database is currently setup. My current flat file database is setup to where a normal MySQL row is its own file, and a MySQL table would be the directory. So for example if you have a user named Jon, there would be a file for the user in a directory named /members/. Within that file would be various information for the user including the users id, rank etc - all separated by tabs, all on separate lines (userid\t4). So here's an example user file: userid 4 notes staff notes: bla bla staff2 notes: bla bla bla username Example So how can I convert the above into their own rows and fields in MySQL? And if possible, could I do thousands of these files at once? Thanks.

  • SQL Server: Is it possible to prevent SQL Agent from failing a step on error?

    - by franklinkj
    I have a stored procedure that runs custom backups for around 60 SQL servers (mixes 2000 through 2008R2). Occasionally, due to issues outside of my control (backup device inaccessible, network error, etc.) an individual backup on one or two databases will fail. This causes this entire step to fail, which means any subsequent backup commands are not executed and half of the databases on a given server may not be backed up. On the 2005+ boxes I am using TRY/CATCH blocks to manage these problems and continue backing up the remaining databases. On a 2000 server however, for example, I have no way to prevent this error from failing the entire step: Msg 3201, Level 16, State 1, Line 1 Cannot open backup device 'db-diff(\PATH\DB-DIFF-03-16-2010.DIF)'. Operating system error 5(Access is denied.). Msg 3013, Level 16, State 1, Line 1 BACKUP DATABASE is terminating abnormally. I am simply asking if anything like this is possible in SQL 2000 or if I need to go in a completely different direction.

  • SQL Server Performance & Latching

    - by Colin
    I have a SQL server 2000 instance which runs several concurrent select statements on a group of 4 or 5 tables. Often the performance of the server during these queries becomes extremely diminished. The querys can take up to 10x as long as other runs of the same query, and it gets to the point where simple operations like getting the table list in object explorer or running sp_who can take several minutes. I've done my best to identify the cause of these issues, and the only performance metric which I've found to be off base is Average Latch Wait time. I've read that over 1 second wait time is bad, and mine ranges anywhere from 20 to 75 seconds under heavy use. So my question is, what could be the issue? Shouldn't SQL be able to handle multiple selects on a single table without losing so much performance? Can anyone suggest somewhere to go from here to investigate this problem? Thanks for the help.

  • Installing Sql Server 2005 SP2 - Getting error on analysis services component

    - by Greg_the_Ant
    At first many of the components didn't install and I followed this workaround (fixing user/SID mappings in registry.) After that everything installed successfully except for analysis services. I am getting the exact same error message as before on analysis services. (Are there other users installed by sql server I'm not aware of perhaps?) Do you guys have any ideas? All of my searches seem to just point to that workaround above that I already did. Error message from log: Product : Analysis Services (MSSQLSERVER) Product Version (Previous): 1399 Product Version (Final) : Status : Failure Log File : C:\Program Files\Microsoft SQL Server\90\Setup Bootstrap\LOG\Hotfix\OLAP9_Hotfix_KB921896_sqlrun_as.msp.log Error Number : 29528 Error Description : MSP Error: 29528 The setup has encountered an unexpected error while Setting Internal Properties.

  • SQL Merge Replication - Filter Sets

    - by Refracted Paladin
    I have a "working" Replication Set in SQL 2005 that we use in house to our users at remote branches on SQL Express 2005. I want to apply a filter to our biggest Set to help minimize the bandwidth impact. What I am asking is what considerations do I need to take into account before throwing a filter on there. Will it cause any issues I should be aware of? Does it affect compression adversely. Will everyone need to reinitialize after applying it? Any heads up or insight would be appreciated. Thanks,

  • How can I start using MS-SQL Server ( express )

    - by Oscar Reyes
    Hello. I have just installed Microsoft SQL Express from here: http://www.microsoft.com/Sqlserver/2005/en/us/express-down.aspx I need it because an example of some code I have uses it. My question is: How do I start using it? Which port it opens by default. All I have after installing it is this: I'm not asking for a full tutorial on how to admin MSSql, just a hint on what to do next. I have downloaded and tested in the past Oracle XE and test it with SQuirreL SQL client with out problems.

  • Is this an example of LINQ-to-SQL?

    - by Edward Tanguay
    I made a little WPF application with a SQL CE database. I built the following code with LINQ to get data out of the database, which was surprisingly easy. So I thought "this must be LINQ-to-SQL". Then I did "add item" and added a "LINQ-to-SQL classes" .dbml file, dragged my table onto the Object Relational Designer but it said, "The selected object uses an unsupported data provider." So then I questioned whether or not the following code actually is LINQ-to-SQL, since it indeed allows me to access data from my SQL CE database file, yet officially "LINQ-to-SQL" seems to be unsupported for SQL CE. So is the following "LINQ-to-SQL" or not? using System.Linq; using System.Data.Linq; using System.Data.Linq.Mapping; using System.Windows; namespace TestLinq22 { public partial class Window1 : Window { public Window1() { InitializeComponent(); MainDB db = new MainDB(@"Data Source=App_Data\Main.sdf"); var customers = from c in db.Customers select new {c.FirstName, c.LastName}; TheListBox.ItemsSource = customers; } } [Database(Name = "MainDB")] public class MainDB : DataContext { public MainDB(string connection) : base(connection) { } public Table<Customers> Customers; } [Table(Name = "Customers")] public class Customers { [Column(DbType = "varchar(100)")] public string FirstName; [Column(DbType = "varchar(100)")] public string LastName; } }

  • SQL Server not releasing Memory

    - by noob2487
    I am using SQL Server 2005. I am running a job which processes around 100 K records. Job runs fine, it takes are 45 mins to execute, which is good. But after that job is processed, I can see instance of SQL Server 2005 still there with around 900 MB of Memory. I waited for around 2 hrs but that memory was not released. Is there any process which takes care of memory here, something like GC (unpredictable) Or am I doing something wrong???

  • What is the best database structure for this scenario?

    - by Ricketts
    I have a database that is holding real estate MLS (Multiple Listing Service) data. Currently, I have a single table that holds all the listing attributes (price, address, sqft, etc.). There are several different property types (residential, commercial, rental, income, land, etc.) and each property type share a majority of the attributes, but there are a few that are unique to that property type. My question is the shared attributes are in excess of 250 fields and this seems like too many fields to have in a single table. My thought is I could break them out into an EAV (Entity-Attribute-Value) format, but I've read many bad things about that and it would make running queries a real pain as any of the 250 fields could be searched on. If I were to go that route, I'd literally have to pull all the data out of the EAV table, grouped by listing id, merge it on the application side, then run my query against the in memory object collection. This also does not seem very efficient. I am looking for some ideas or recommendations on which way to proceed. Perhaps the 250+ field table is the only way to proceed. Just as a note, I'm using SQL Server 2012, .NET 4.5 w/ Entity Framework 5, C# and data is passed to asp.net web application via WCF service. Thanks in advance.

  • Delay index build until SQL Server table load is complete with SSIS

    - by Mattew
    I have a large table that I am updating. Is it possible to disable index updates on the destination table until the load is complete? It seems like a waste for it to be constantly updating the index with each commit. I can just drop and recreate the index before and after the load, I just want to know if there is a quick way to configure that in the OLEDB or SQL Server destination. Server is Windows Server 2003 Datacenter Edition, running SQL Server 2008 Standard Edition with SSIS.

  • SQL Server getdate() to a string like "2009-12-20"

    - by Adam Kane
    In Microsoft SQL Server 2005 and .NET 2.0, I want to convert the current date to a string of this format: "YYYY-MM-DD". For example, December 12th 2009 would become "2009-12-20". How do I do this in SQL. The context of this SQL statement in the table definiton. In other words, this is the default value. So when a new record is created the default value of the current date is stored as a string in the above format. I'm trying: SELECT CONVERT(VARCHAR(10), GETDATE(), 102) AS [YYYY.MM.DD] But SQL server keeps converting that to: ('SELECT CONVERT(VARCHAR(10), GETDATE(), 102) AS [YYYY.MM.DD]') so the result is just: 'SELECT CONVERT(VARCHAR(10), GETDATE(), 102) AS [YYYY.MM.DD]' Here's a screen shot of what the Visual Studio server explorer, table, table definition, properties shows: These wrapper bits are being adding automatically and converting it all to literal string: (N' ') Here's the reason I'm trying to use something other than the basic DATETIME I was using previously: This is the error I get when hooking everything to an ASP.NET GridView and try to do an update via the grid view: Server Error in '/' Application. The version of SQL Server in use does not support datatype 'date'. Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. Exception Details: System.ArgumentException: The version of SQL Server in use does not support datatype 'date'. Source Error: An unhandled exception was generated during the execution of the current web request. Information regarding the origin and location of the exception can be identified using the exception stack trace below. Stack Trace: [ArgumentException: The version of SQL Server in use does not support datatype 'date'.] Note: I've added a related question to try to get around the SQL Server in use does not support datatype 'date' error so that I can use a DATETIME as recommended.

  • SQL Server Authentication vs Windows Authentication

    - by Nandu
    Hi, I am a SQL Server newbie and would really appreciate any help. I have created a new login (test2) with sql server authentication and granted select & vierw definition permission on another schema (test1) to test2. I am however not able to see the objects of test1 in the object explorer. However I can select the objects from the Query Window. Since this new login is being used to develop reports the user would like to view the objects in the Object Explorer. Another user test3 created using windows authentication and similar permissions is able to see test1's objects in the explorer. Please let me if this is the cause and if not how can help test2 see the objects in Object Explorer.

  • What database strategy to choose for a large web application

    - by Snoopy
    I have to rewrite a large database application, running on 32 servers. The hardware is up to date, each machine has two quad core Xeon and 32 GByte RAM. The database is multi-tenant, each customer has his own file, around 5 to 10 GByte each. I run around 50 databases on this hardware. The app is open to the web, so I have no control on the load. There are no really complex queries, so SQL is not required if there is a better solution. The databases get updated via FTP every day at midnight. The database is read-only. C# is my favourite language and I want to use ASP.NET MVC. I thought about the following options: Use two big SQL servers running SQL Server 2012 to serve the 32 servers with data. On the 32 servers running IIS hosting providing REST services. Denormalize the database and use Redis on each webserver. Use booksleeve as a Redis client. Use a combination of SQL Server and Redis Use SQL Server 2012 together with Hadoop Use Hadoop without SQL Server What is the best way for a read-only database, to get the best performance without loosing maintainability? Does Map-Reduce make sense at all in such a scenario? The reason for the rewrite is, the old app written in C++ with ISAM technology is too slow, the interfaces are old fashioned and not nice to use from an website, especially when using ajax. The app uses a relational datamodel with many tables, but it is possible to write one accerlerator table where all queries can be performed on, and all other information from the other tables are possible by a simple key lookup.

  • Integration transport choice (Oracle + SQL Server)

    - by lak-b
    We have several systems with Oracle (A) and SQL Server (B) databases on backend. I have to consolidate data from those systems into the new SQL Server database. Something like that: (A) =>|---------------| | some software | => SQL Server (B) =>|---------------| where some software is: transport (A and B systems located in the network) processing business logic (custom .NET code) Due to first point, I need some queue software or something similar (like MSMQ, Service Broker or something). In another hand, I can implement a web-service instead of queue. (A) =>|---------------|-------------| | queue/service | custom code | => SQL Server (B) =>|---------------|-------------| The question is: which queue/transport framework should I use with Oracle and SQL Server databases? It would be nice, if I can post messages to MSMQ in both Oracle and SQL Server stored procedures (can I?) It would be nice, if I can call a web-service in both Oracle and SQL Server stored procedures (can I?) It would be nice, if I can use something similar in both Oracle and SQL Server stored procedures (what exactly?) What software should I prefer to my requirements?

  • Dynamic access to tables from another database inside an user function

    - by Alberto Martinez
    I have an user defined table function in SQL Server that aggregate data from several tables including a couple of tables of another database. That is done hardcoding the name of the database in the queries, but we want to make the database name configurable (because our databases usually share the server with the databases of other applications). I tried to construct a dynamic query string inside the function using the database name that is stored in a configuration table, but: When I tried exec(@sqlStatement) SQL Server said that execute string is not allowed inside a function. Then I tried exec sp_executesql @sqlStatement and the function was created, but when you execute it SQL Server says that inside a function you can only run extended functions and procedures. So the question is: is possible create a function or stored procedure that access a table in another database without having to recreate the function when the database name is different? TIA.

  • Oracle Database 11g R2 támogatott SAP alatt is

    - by Lajos Sárecz
    Húsvét óta már SAP alatt is használható az Oracle Database 11g R2. Köztudott, hogy az SAP csak a Release 2-re ad ki támogatást, így ez most egy igazán örömteli hír az SAP felhasználóknak, hiszen az alábbi 11g R2 újdonságokat tudják alkalmazni SAP környezetben: • Advanced Compression opció (táblára, RMAN mentésre, expdp-re, Data Guard hálózatra) • Real Application Testing • Oracle Database 11g Release 2 Database Vault • Oracle Database 11g Release 2 RAC • Advanced Encryption táblaterekre, RMAN mentésekre, expdp-re, Data Guard hálózatra • Direct NFS • Deferred Segments • Online Patching Azaz például tömöríthetové válik az SAP adatbázisa, vagy az abból készített mentések. Az eddigi tapasztalatok szerint a tömörítés aránya adatbázistól függoen 2-4-szeres. Az adatbázis upgrade és minden egyéb adatbázis infrastruktúrát érinto változatatás kockázata jelentosen csökkentheto lesz a Real Application Testing alkalmazásával. A rendszergazdai szerepkörök szeparaláhatóvá válnak a Database Vault felhasználásával. A Real Application Clusters 11g R2 újdonságai is elérheto lesznek. A Transparent Data Encryption révén a táblaterek és a mentések titkosíthatók úgy, hogy az alkalmazás számára mindez transzparens, azonban a médiához közvetlenül hozzáférve nem lesznek visszafejthetok az adatok. Támogatott lesz a Direct NFS kliens, ezzel NFS elérési sebesség jelentosen javul. A Deffered Segments révén pedig a tábla szegmensek csak akkor kerülnek lefoglalásra, amikor adat kerül a táblába. Ez azért hasznos, mert általában alkalmazások telepítésekor létrejön minden tábla, azonban sok táblába nem kerül adat. Ezáltal mind a telepítés ideje, mind az adatbázis mérete csökkentheto. Az Online Patching pedig lehetové teszi a leállításmentes patch telepítést. Hát azt gondolom ezek vonzó lehetoségek, érdemes betervezni a közeljövobe az SAP rendszerek alatti adatbázis frissítését, hiszen a 10g verzió Premier Support idén nyáron lejár. Az upgrade-hez pedig mindenképp javaslom a Real Application Testing használatát, amivel az éles terhelés mellett teszthelheto teszt környezetben az upgrade. A Sun Oracle Database Machine és az Exadata sajnos még nem támogatott SAP alatt, mivel az ASM certifikáció még nem zárult le. A hírek szerint 2011 elejére várható, hogy ez megtörténik.

  • New P6 Reporting Database R2

    - by mark.kromer
    Along with our announced GA release of P6 Analytics R1 recently, you may have noticed that when you purchase P6 Analytics, we provide a restricted use license for P6 Reporting Database R2. This represent an updated version of the previous P6 Reporting Database 6.2 and can be purchased individually on a per-CPU basis. Typically, you will want just the reporting database if you would like the P6 data warehouse components such as the ETL, data models, ODS and star schemas in order to report on that data with another reporting tool other than Oracle. The P6 Analytics solution will only work on Oracle BI (OBI). But I pasted below some examples of a simplistic matrix report that I built from the P6 Reporting Database using Microsoft SQL Server Reporting Services. This is the Report Builder tool which is very similar to other similar tools to build reports on the market today such as Crystal Reports or Oracle BI Publisher. This is an example of what you can do (in a very simple format) by using the P6 Reporting Database without P6 Analytics: Here is a quick run-down of some of the key new features in P6 Reporting Database R2 that were added as enhancements to the 6.2 version: • 4 new star schemas (improved projects star, project history, resource utilization and resource allocation) • Improved ETL performance and reliability • P6 security is inherited at the star schema level • Custom P6 project, activity & resource codes are now available as customizable dimensions in the star schemas • Time-phase data down to the data is now available from the star schemas • An updated Operational Data Store (ODS) for operational reporting that includes the WBS hierarchy • The ODS now includes daily spreads for activity and resource assignments

  • Large invoice database structure and rendering

    - by user132624
    Our client has a MS SQL database that has 1 million customer invoice records in it. Using the database, our client wants its customers to be able to log into a frontend web site and then be able to view, modify and download their company’s invoices. Given the size of the database and the large number of customers who may log into the web site at any time, we are concerned about data base engine performance and web page invoice rendering performance. The 1 million invoice database is for just 90 days sales, so we will remove invoices over 90 days old from the database. Most of the invoices have multiple line items. We can easily convert our invoices into various data formats so for example it is easy for us to convert to and from SQL to XML with related schema and XSLT. Any data conversion would be done on another server so as not to burden the web interface server. We have tentatively decided to run the web site on a .NET Framework IIS web server using MS SQL on MS Azure. How would you suggest we structure our database for best performance? For example, should we put all the invoices of all customers located within the same 5 digit or 6 digit zip codes into the same table? Or could we set up a separate home directory for each customer on IIS and place each customer’s invoices in each customer’s home directory in XML format? And secondly what would you suggest would be the best method to render customer invoices on a web page and allow customers to modify for best performance? The ADO.net XML Data Set looks intriguing to us as a method, but we have never used it.

  • Remote Access to MSSQL Database From 1&1 Hosting [duplicate]

    - by Zerkey
    This question already has an answer here: How to find web hosting that meets my requirements? 5 answers I just paid ($6 /month) for shared Windows hosting through 1&1 hosting. I was having trouble connecting to my database from home, so I sent an email to support. I received the following response: As we checked your concern here in our end, please be advised that due to limitation of Shared Hosting services, there is no option to connect the database to your SQL Management Studio or through Visual Studio. It is only possible for Dedicated Server package. You may only access the database using MyLittleAdmin at the Control Panel. A dedicated server is like $200 per month! What is the point of having database access only through a web console? I feel I am missing something here, or maybe the support agent is. Is there a way to access my MS SQL database on their servers through Visual Studio or SQL Management Studio from my machine? If not, is there a web host who allows this for less than $200 a month? EDIT: Marked as duplicate... I'm not asking for a list of web hosts, I'm asking how to remotely connect to my MSSQL database through 1&1's services.

  • Best approach for a clinic database

    - by user18013
    As a practical assignment for the database course I'm taking I've been instructed to create a database for a local clinic, I've meet with the doctors a couple of times and discussed the information that needs to be stored in the database from personal to medical. Now I'm facing a tough decision because I've been given two choices: either to implement the database as a "local website" which only operates inside the clinic via WiFi, or to implement the front-end as a regular desktop application connecting to a shared database. Note: I've a 40 days deadline to deliver the first prototype and meet with my client. My questions are: 1- which approach should I go with given that I've more experience with desktop applications programming than web? 2- if I go with desktop front-ends what would be the best way to synchronize the database between all clients?? I've no experience and having searched for an answer a lot but came up with nothing detailed on this matter. 3- if I go with the web solution which choice would be best PHP & MySQL or ASP.NET & SQL Server or a different combination?? (given that my knowledge in both PHP & ASP.NET are nearly the same).

  • Need database selection advise

    - by jacknad
    I know this is considered a bad question since there is no correct answer, but I need to decide on a database for embedded linux (DaVinci 368 based) hardware and I've never had to produce a design with a database before. Each record will probably contain less than 1000 images with associated alpha-numeric data and the mass storage will be some kind of flash drive. Only one user needs access to the data at a time. MySQL claims to be "The world's most popular open source database" but SQLite claims to be "the most widely deployed SQL database engine in the world." Perhaps there is another that is also the best in the world? Which is easiest to use for a database newbie? Should I just flip a coin? Does it really matter which one I pick? Do I even need to use a database software package or should I roll my own? I won't need bells and whistles like sorting, but I'll probably need to delete the oldest records to make room for new ones if the storage fills up.
