Hi,

I'm doing this query:

DECLARE @TESTE BIGINT
DECLARE @DB VARCHAR(100)

SET @DB ='SGCTCENTRAL'

SET @TESTE = ('SELECT MAX(CODIGO) FROM '+@DB+'.DBO.SINCRONISMO')

SELECT @TESTE

I get this message:

Msg 8114, Level 16, State 5, Line 8
Error converting data type varchar to bigint.

Can someone help, please.

Thank you
Luis Cazares

You're setting your variable to 'SELECT MAX(CODIGO) FROM SGCTCENTRAL.DBO.SINCRONISMO' and that is a string value. You need to use dynamic code by using sp_executesql (preferred method) or EXECUTE().
If your query is as simple as this, you don't need to use the @TESTE variable. You could execute the SELECT directly.

SET @TESTE = ('SELECT MAX(CODIGO) FROM '+@DB+'.DBO.SINCRONISMO')

declare @SQLCmd nvarchar(max),
@SQLParm nvarchar(max),
@TESTE bigint,
@DB nvarchar(128);

SET @DB = N'SGCTCENTRAL';
set @SQLCmd = N'SELECT @TESTOUT = MAX(CODIGO) FROM '+@DB+'.DBO.SINCRONISMO');
set @SQLParm = N'@TESTOUT bigint';

exec sp_executesql @SQLCmd, @SQLParm, N'@TESTOUT = @TESTE OUTPUT';
select @TESTE




Not sure if I did all of that correctly as I did it from memory and I have not tested in my sandbox database. At least it gives you an idea of how to proceed if it works.

Cool
