• SSIS DTS Package flat file error - "The file name specified in the connection was not valid"

  - by MisterZimbu

  I have a pretty basic SSIS package that is attempting to read a file hosted on a share, and import its contents to a database table. The package runs fine when I run it manually within SSIS. However, when I set up a SQL Agent job and attempt to execute it, I get the following error: Executed as user: DOMAIN\UserName. Microsoft (R) SQL Server Execute Package Utility Version 9.00.3042.00 for 64-bit Copyright (C) Microsoft Corp 1984-2005. All rights reserved. Started: 10:14:17 AM Error: 2010-05-03 10:14:17.75 Code: 0xC001401E Source: DataImport Connection manager "Data File Local" Description: The file name "\10.1.1.159\llpf\datafile.dat" specified in the connection was not valid. End Error Error: 2010-05-03 10:14:17.75 Code: 0xC001401D Source: DataAnimalImport Description: Connection "Data File Local" failed validation. End Error DTExec: The package execution returned DTSER_FAILURE (1). Started: 10:14:17 AM Finished: 10:14:17 AM Elapsed: 0.594 seconds. The package execution failed. The step failed. This leads me to believe it's a permissions issue, but every attempt I've made to fix it has failed. What I've tried so far: Run as the SQL Agent account (DOMAIN\SqlAgent) - yields same error. DOMAIN\SqlAgent has "Full Control" permissions on both the share and the uploaded file. Set up a proxy account with a different account's credentials (DOMAIN\Account) - yields same error. Like above, "Full Control" permissions were given over the share to that account. Gave "Everyone" full control permissions over the share (temporarily!). Yielded same error. Manually copied the file to a local path and tested with the SQL Agent account. Worked properly. Added an ActiveX script task that would first copy the remotely hosted file to a local path, and then have the DTS package reference the local file. Gave a completely nondescriptive (even by SSIS standards) error when trying to run the script. Set up a proxy account, using my own personal account's credentials - worked correctly. However, this is not an acceptable solution as there are password policies in place on my account, as well as being a bad practice to set things up this way in general. Any ideas? I'm still convinced it's a permissions issue. However, what I've read from various searches more or less says giving the executing account permissions on the share should work. However, this is not the case here (unless I'm missing something obscure when I'm setting up permissions on the share).

• nodejs and database communication - how?

  - by FractalizeR

  Hello. I've heard much good about nodejs and writting client-server application with it. But I can't get, for example, when developing IM client-server application, how nodejs server script is supposed to talk to database server to actually store it's data? Or may be I miss something and nodejs server scripts are not supposed to do that? If so, please, push me to correct direction.

• Accessing SQL Data Services via ADO.NET Data Service Client Library

  - by Mehmet Aras

  Is this possible? Basically I would like to use SQL Data Services REST interface and let the ADO.NET Data Service Client library handle communication details and generate the entities that I can use. I looked at the samples in February release of Azure services kit but the samples in there are using HttpWebRequest and HttpWebResponse to consume SQL Data Services RESTfully. I was hoping to use ADO.NET Data Service Client library to abstract low-level details away.

• FileFinder using SQL

  - by James Morgan

  I was thinking of working on a project while I have some free time and this one looks pretty nice: http://mindprod.com/project/filefinder.html One thing I'm wondering about is that will it really be much faster compared to the regular windows search if I use SQL? I'm planning to use MySQL since it's open source. Also, do I need to be good at databases for this? I have basic knowledge about relational databases and can definitely make some SQL statements. Thanks.

• Am I Leaking ADO.NET Connections?

  - by HardCode

  Here is an example of my code in a DAL. All calls to the database's Stored Procedures are structured this way, and there is no in-line SQL. Friend Shared Function Save(ByVal s As MyClass) As Boolean Dim cn As SqlClient.SqlConnection = Dal.Connections.MyAppConnection Dim cmd As New SqlClient.SqlCommand Try cmd.Connection = cn cmd.CommandType = CommandType.StoredProcedure cmd.CommandText = "proc_save_my_class" cmd.Parameters.AddWithValue("@param1", s.Foo) cmd.Parameters.AddWithValue("@param2", s.Bar) Return True Finally Dal.Utility.CleanupAdoObjects(cmd, cn) End Try End Function Here is the Connection factory (if I am using the correct term): Friend Shared Function MyAppConnection() As SqlClient.SqlConnection Dim cn As New SqlClient.SqlConnection(ConfigurationManager.ConnectionStrings("MyConnectionString").ToString) cn.Open() If cn.State <> ConnectionState.Open Then ' CriticalException is a custom object inheriting from Exception. Throw New CriticalException("Could not connect to the database.") Else Return cn End If End Function Here is the Dal.Utility.CleaupAdoObjects() function: Friend Shared Sub CleanupAdoObjects(ByVal cmd As SqlCommand, ByVal cn As SqlConnection) If cmd IsNot Nothing Then cmd.Dispose() If cn IsNot Nothing AndAlso cn.State <> ConnectionState.Closed Then cn.Close() End Sub I am getting a lot of "Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding." error messages reported by the users. The application's DAL opens a connection, reads or saves data, and closes it. No connections are ever left open - intentionally! There is nothing obvious on the Windows 2000 Server hosting the SQL Server 2000 that would indicate a problem. Nothing in the Event Logs and nothing in the SQL Server logs. The timeouts happen randomly - I cannot reproduce. It happens early in the day with only 1 to 5 users in the system. It also happens with around 50 users in the system. The most connections to SQL Server via Performance Monitor, for all databases, has been about 74. The timeouts happen in code that both saves to, and reads from, the database in different parts of the application. The stack trace does not point to one or two offending DAL functions. It's happened in many different places. Does my ADO.NET code appear to be able to leak connections? I've goolged around a bit, and I've read that if the connection pool fills up, this can happen. However, I'm not explicitly setting any connection pooling. I've even tried to increase the Connection Timeout in the connection string, but timeouts happen long before the 300 second (5 minute) value: <add name="MyConnectionString" connectionString="Data Source=MyServer;Initial Catalog=MyDatabase;Integrated Security=SSPI;Connection Timeout=300;"/> I'm at a total loss already as to what is causing these Timeout issues. Any ideas are appreciated.

• How do I get ELMAH to work with SQL Server (permission problems)

  - by Gary McGill

  I've got ELMAH working on my (Cassini) development server, and was quite happy with it, but now that I'm trying to move everything to my production server (IIS7), the honeymoon looks like being over. I've got past the "gotcha" with IIS7, which frankly could have been better highlighted in the documentation, and if I just use the in-memory log then it works. However, I'm trying to get it to use the SQL Server log (as I do on my development system), and I'm getting an error along the lines of: The EXECUTE permission was denied on the object ELMAH_GetErrorsXml Well, fine. I know how to grant database permissions, but I'm really struggling to understand which user and which stored procs/tables I need to grant access to. The thing that's really confusing me is that I didn't have to do anything like this to get it to work on my development server. The only difference I can see is that on my development server it seems to connect as NT AUTHORITY\IUSR, whereas on my production server it seems to connect as NT AUTHORITY\NETWORK SERVICE. (It's just using a trusted connection so I've not explicitly configured it to do that - I presume it's to do with the web server). UPDATE: I've since established that because I'm using Cassini, it was actually logging in as me (an admin) and not IUSR, which explains why I didn't get any permission problems. On my development server, the IUSR account is a member of the public database role, and has access to the required database (again as "public"). There's no explicit granting of object-level permissions. [See update above - this is irrelevant]. On my production server, I've added NETWORK SERVICE in exactly the same way (public database role, explicit access to the database as "public"). Yet, I get this permission error. Why?!! [See update above - the only reason I don't get a permission error is because I'm running as an admin]. And, of course, if the fact that it works locally is just "luck", I will need to know which SPs/tables to grant access to. My guess would be all 3 SPs and not the table, but it would be good (again) to see some documentation that makes this explicit.

• SQL Group By Modulo of Row Count

  - by Alex Czarto

  I have the following sample data: Id Name Quantity 1 Red 1 2 Red 3 3 Blue 1 4 Red 1 5 Yellow 3 So for this example, there are a total of 5 Red, 1 Blue, and 3 Yellow. I am looking for a way to group them by Color, but with a maximum of 2 items per group (sorting is not important). Like so: Name QuantityInPackage Red 2 Red 2 Red 1 Blue 1 Yellow 2 Yellow 1 Any suggestions on how to accomplish this using T-SQL on MS-SQL 2005?

• Simple ASP.NET Database Query

  - by Steven

  I have loaded my database with one table under "Data Connections" in the "Server Explorer" pane. What is the standard / best-practices way to handle a simple query in a VB ASPX page? My left <div> would be a set of form elements to filter rows, and when the button is clicked, the main <div> would show the columns I want for the rows returned. Note: Answers in C# are okay too, I'll just translate.

• SQL string formatter

  - by Paul D. Eden

  Does anyone know of a program, a utility, or some programmatic library, preferably for Linux, that takes an unformatted SQL string and pretty prints it? For example I would like the following select * from users where name = 'Paul' be changed to something like this select * from users where name = 'Paul' The exact formatting is not important. I just need something to take a large SQL string and break it up into something more readable.

• Better languages than SQL for stored procedures

  - by Ken Paul

  I'm getting increasingly frustrated with the limitations and verbosity required to actually commit some business logic to stored procedures, using languages such as Transact-SQL or PL/SQL. I would love to convert some current databases to Oracle and take advantage of its support for Java stored procedures, but that option is not available at the moment. What alternatives would you recommend in the way of databases that support stored procedures in other languages?

• Style guide for database metadata naming

  - by Nulldevice

  We want to establish some database metadata naming rules in our new project. For example: tables are named as nouns in a plural form (courses, books, lessons) if present, an adjective goes before a noun in a table name and is separated by an underscore (red_books, new_lessons) table index column is always named "id" foreign key names are derived from a table name with suffix _id (book_id, red_book_id) so on Does someone know any guide like this?

• Sql Server Select Command and too much data sent to winforms application

  - by ThanosPapathanasiou

  When you have an application and send a select command, the sql server gathers all the data and sends them back to your application and fills your datagrid (for example) If you performed the same select command in sql management studio, immediately as the query starts running and finding data the results panel would start filling with the data found. How can I do that for my winforms application? Is there a technique or a standard method of doing something like this? Links to good examples would be an immense help. thanks
