T-Sql getting data from tempdb table

Question

I'm using Microsoft SQL Server 2008 R2 (RTM) - 10.50.1600.1 (X64) and I'm trying to make a SELECT statement to a table that have been created like this:

DECLARE @Sql AS VARCHAR(1500)

SET @Sql = 'SELECT 1 AS id, ''123'' AS value INTO #tmp_prueba'

EXECUTE ( @Sql )

SELECT * FROM #tmp_prueba

But I'm noticed that the table not exists

How can I get the data from the table?

Answer 1

The temporary table that you created in @sql is out-of-scope of the outer query.

Here is one way to do what you want:

DECLARE @Sql AS VARCHAR(1500);

SET @Sql = 'SELECT 1 AS id, ''123'' AS value INTO #tmp_prueba;
            select * from #tmp_prueba'

create table #tmp_prueba (id int, value varchar(255));

insert into #tmp_prueba
    EXECUTE( @Sql );

SELECT * FROM #tmp_prueba

Here are the changes. FIrst, I select everything from the temproary table in the @sql query. Second, I create a temporary table (with the same name in this case) to hold the results. Now, I can insert the results from the execute into the table. Voila! The data is there.
