I have the following code:
use mydb;
declare @sql nvarchar(1000)
declare @Table nvarchar(19)
set @sql = 'select ''dbo.myTable_''
+ substring(CONVERT(varchar(
+ ''_'' + substring(CONVERT(varchar(
exec sp_executesql @sql, @Table
declare @mySQL nvarchar(1000)
SET @mySQL = 'SELECT top 10 * FROM ' + @Table
EXEC(@mySQL)
..but instead of returning the top 10 records from dbo.myTable_01_2008, all that's returned is the name of the table - dbo.myTable_01_2008.
Does anyone know what I'm doing wrong?

Thanks, simonet.
I added a FROM clause to @sql but I'm still seeing the same error:
use mydb;
declare @sql nvarchar(1000)
declare @Table nvarchar(19)
set @sql = 'select top 1 ''dbo.MyTable_''
+ substring(CONVERT(varchar(
+ ''_'' + substring(CONVERT(varchar(
+ 'FROM dbo.MyTable_01_2008'
exec sp_executesql @sql, @Table
declare @mySQL nvarchar(1000)
SET @mySQL = 'SELECT top 10 * FROM ' + @Table
EXEC (@mySQL)
Any other suggestions?
Nevermind - I've learned that it's never a good idea to use dynamic table names in SQL (http://www.sommarskog.se/

+ ''_'' + substring(CONVERT(varchar(
