Question

Was trying to select…into a temp Table #TempTable in sp_Executedsql.
Not its successfully inserted or not but there Messages there written
(359 row(s) affected) that mean successful inserted?
Script below

DECLARE @Sql NVARCHAR(MAX);
SET @Sql = 'select distinct Coloum1,Coloum2 into #TempTable 
            from SPCTable with(nolock)
            where Convert(varchar(10), Date_Tm, 120) Between @Date_From And @Date_To';

SET @Sql = 'DECLARE @Date_From VARCHAR(10);
            DECLARE @Date_To VARCHAR(10);
            SET @Date_From = '''+CONVERT(VARCHAR(10),DATEADD(d,DATEDIFF(d,0,GETDATE()),0)-1,120)+''';
            SET @Date_To = '''+CONVERT(VARCHAR(10),DATEADD(d,DATEDIFF(d,0,GETDATE()),0)-1,120)+''';
            '+ @Sql;

EXECUTE sp_executesql @Sql;

After executed,its return me on messages (359 row(s) affected).
Next when trying to select out the data from #TempTable.

Select * From #TempTable;

Its return me:

Msg 208, Level 16, State 0, Line 2
Invalid object name '#TempTable'.

Suspected its working only the ‘select’ section only. The insert is not working.
how fix it?

Answer 1

Local temporary table #table_name is visible in current session only, global temporary ##table_name tables are visible in all sessions. Both lives until their session is closed.
sp_executesql – creates its own session (maybe word “scope” would be better) so that’s why it happens.
