Question

I am importing an intermediate result of query into a temp table for further use, so I used a #temp table to maintain the same schema as

select * into # temp from schema.tableName where 1<>1;

insert into # temp from exec(table)

While I am doing this statement as a variable to pass the different tableName its not working

SET @TEMPSCHEMA = 'SELECT * INTO #temp FROM ' + @PKSchema + '.dbo.' + @PKTableName + ' WHERE 1<>1;'

exec(@TEMPSCHEMA)


INSERT INTO #temp

EXEC ( @SELECTSTATEMENT

)

however after exec statement it is not taking the values to the temp table.

it is showing the invalid object id #temp

Answer 1

This is because the scope of the EXEC statement is different to the scope of the containing sproc. That is, your call to EXEC is creating the temporary table, and then it’s being automatically dropped as the scope for the EXEC is left. You basically have to do the whole lot inside the one EXEC statement:

DECLARE @sql VARCHAR(MAX)
SET @sql = 'SELECT * INTO #temp
            FROM ' + @PKSchema + '.dbo.' + @PKTableName + ' WHERE 1<>1
            INSERT INTO #temp ...'

EXEC(@sql)
