无法将过程存储到动态临时表中

Question

I have a stored procedure that returns columns . This stored procedure is mainly being used by other query for functional reasons

So my stored procedure:

IF OBJECT_ID ( 'dbo.ProcDim', 'P' ) IS NOT NULL 
    DROP PROCEDURE dbo.ProcDim;
GO
CREATE PROCEDURE dbo.ProcDim
                            @Dim1 nvarchar(50), 
                            @Dim2 nvarchar(50) 
AS 
    SET NOCOUNT ON;
    IF OBJECT_ID('tempdb..#TMP1') IS NOT NULL
    DROP TABLE #TMP1

    SELECT  
    INTO    #TMP1           
    FROM  DBase.dbo.Table1  AS Parameter
    WHERE Parameter.Dim1    = @Dim1 
    AND   Parameter.Dim2    = @Dim2;
GO

EXECUTE dbo.ProcDim N'value1', N'value2';
SELECT * from #TMP1

So when i excute my procedure without #TMP1 work fine but i want to insert the result into temp table

Answer 1

You can't use temporary table in such a manner.

By this code: SELECT INTO #TMP1 you're implicity creating temporary table, and it is accessible in the scope of your stored procedure - but not outside of this scope.

If you need this temporary table to be accessible outside of stored procedure, you have to remove INTO #TMP1 from stored procedure and explicitly create it outside:

create table #tmp1 (columns_definitions_here)

insert into #tmp1
exec  dbo.ProcDim N'value1', N'value2';

select * from #TMP1

Notice you have to explicitly create temporary table in this case, supplying all column names and their data types.

Alternatively you can change your stored procedure to be user-defined table function, and in this case you will be able to implicitly create and populate your temporary table:

create function dbo.FuncDim
(
    @Dim1 nvarchar(50), 
    @Dim2 nvarchar(50)
)
returns @result TABLE (columns_definition_here) 
as
begin
    ... your code
   return
end

select  *
into  #TMP1
from dbo.FuncDim(@Dim1, @Dim2)

Answer 2

Temp tables are scoped (in this case) to the stored procedure in which they're created. That is, when your stored procedure completes, the temp table is dropped.

If you need the contents of the temp table, select from it before the end of the procedure - IOW, select * from #TMP1 should be the output of the procedure, not a separate statement executed outside of it.

While @AndyKorneyev is good enough, there're some caveats in it. For example, you have to keep structure of the table and dataset returned by procedure synchronized, also insert into exec calls cannot be nested.

So, as far as I know - there're no silver bullet in terms of sharing data between procedures, so you have to think about best suitable solution for you case.

Just to give your more information about topic - here's nice article by Sommarskog concerning sharing data between stored procedures.

For example, I also sometimes use 'shared table' solution (be warned it could lead to recompilations):

create procedure dbo.p_test
as
begin
    set nocount on

    insert into #temp_shared (col1, col2)
    select col1, col2 from <...>
end
go

-- creating table so it'll be used inside temp
create table #temp ...

exec dbo.p_test

-- now you have data in your table
select * from #temp

--#TMP1 is a local temp table its, Scope is limited to its query layer only.

if you want to access it out side its query layer use global temp table as ##TMP1

IF OBJECT_ID ( 'dbo.ProcDim', 'P' ) IS NOT NULL 
    DROP PROCEDURE dbo.ProcDim;
GO
CREATE PROCEDURE dbo.ProcDim
                            @Dim1 nvarchar(50), 
                            @Dim2 nvarchar(50) 
AS 
    SET NOCOUNT ON;
    IF OBJECT_ID('tempdb..##TMP1') IS NOT NULL
    DROP TABLE ##TMP1

    SELECT  
    INTO    ##TMP1           
    FROM  DBase.dbo.Table1  AS Parameter
    WHERE Parameter.Dim1    = @Dim1 
    AND   Parameter.Dim2    = @Dim2;
GO

EXECUTE dbo.ProcDim N'value1', N'value2';
SELECT * from ##TMP1

Temp tables are scoped to current connection. So that is the reason why you are not able to get the result.

If you want query the temp table, then query in procedure itself.

IF OBJECT_ID ( 'dbo.ProcDim', 'P' ) IS NOT NULL 
DROP PROCEDURE dbo.ProcDim;
GO
CREATE PROCEDURE dbo.ProcDim
                        @Dim1 nvarchar(50), 
                        @Dim2 nvarchar(50) 
AS 
SET NOCOUNT ON;
IF OBJECT_ID('tempdb..#TMP1') IS NOT NULL
DROP TABLE #TMP1

SELECT  *
INTO    #TMP1           
FROM  DBase.dbo.Table1  AS Parameter
WHERE Parameter.Dim1    = @Dim1 
AND   Parameter.Dim2    = @Dim2;

---Here write query to fetch the data from temp table.
SELECT * FROM  #TMP1 

GO

Now give a try to execute statement.

  EXECUTE dbo.ProcDim N'value1', N'value2';

I don't prefer Stored procedures to use in this way. For your requirement you can go for Functions instead.
