Local Variables in User Defined Functions

I'm having a problem declaring variables in UDFs. Are they allowed? Can someone send me some syntax to see what I am doing wrong?You can only declare local variables in scalar and table-valued functions. To understand the difference go to Templates tab of Object Browser in QA and select Functions folder.|||I am using a table function with the following syntax:

create function dbo.TestFunction (@.InputVariable int)
returns table
with encryption
as

declare @.LocalVariable smalldatetime

select @.LocalVariable = ABCDate from ABCTable where rowid = @.InputVariable

return(
select * from XYZTable where XYZDate < @.LocalVariable
)

Any thoughts?

If you want "returns table" then you can't have any other statement except for "return (select...)", while if you want to have local variables then you need "returns @.tbl table (<structure>) with encryption as begin...<other statements>...end" Review the templates in QA and make a decision.|||gtocha...thanks

local variable in select statement

Hello to all,
are there that have already used a select like the
following to catch backup history rows from different SQL
server defined as linked server
select *
from @.my_system.msdb.dbo.sysdbmaintplan_history
where .........
the local variable @...... set using a cursor seams to be
not sintactically correct.
Any idea
Thanks marinoYou need to use dynamic sql if the servername changes
e.g.
declare @.cmd nvarchar(500)
set @.cmd = N'select * from ' + @.my_system +
N'.msdb.dbo.sysdbmaintplan_history'
exec sp_executesql @.cmd
For more on dynamic sql see

local database "XXYYZZ" is not defined in configuration

I'm quite addicted to Patterns-&-Practices Enterprise.Library.Data module, but I can't get it to access a SQL Server Express Database. I've tried several different .CONFIG files and a unch of different settings and I keep getting:

The local database "XXYYZZ" is not defined in configuration.

I'm using Visual Studio 2005 C# in a WinForms application.

Can Microsoft.Practices.EnterpriseLibrary.Data access SQL Server Express Database?

<configuration>

<configSections>

<section name="dataConfiguration" type="Microsoft.Practices.EnterpriseLibrary.Data.Configuration.DatabaseSettings, Microsoft.Practices.EnterpriseLibrary.Data, Version=2.0.0.0, Culture=neutral, PublicKeyToken=null" />

</configSections>

<dataConfiguration defaultDatabase="Connection String" />

<connectionStrings>

<add name="myDb" connectionString="Database=Database;Server=(local)\SQLEXPRESS;AttachDbFilename=C:\myDir\myDBname.mdf;Integrated Security=True;User Instance=True"

providerName="System.Data.SqlClient" />

</connectionStrings>

</configuration>

- and it's use

Database db = DatabaseFactory.CreateDatabase("myDb");
DbCommand dbC = db.GetStoredProcCommand("mySPname");
db.AddInParameter(dbC, "MyParameterName", DbType.Int32, MyIntVal);
DataSet ds = db.ExecuteDataSet(dbC);

Needs this stuff too ...

using System.Data;

using System.Data.SqlTypes;

using System.Data.SqlClient;

using Microsoft.Practices.EnterpriseLibrary.Data;

using Microsoft.Practices.EnterpriseLibrary.Data.Sql;

using System.Data.Common;

|||As the Elib cannot find the "mydb" entry, it seems that the ELIB is requesting the wrong (in terms of your thinking) .config file. See if you are pointing to the right config file.
