stored procedure an insert exec statement cannot be nested - sql

Question

I have the following stored procedure which calls another stored procedure dbo.[spGetResult]
;WITH CTE
AS
(
SELECT 0 AS [Level],PNLId , PNLParentId, PNLName
FROM [dbo].[DimPNL]
WHERE PNLParentId IS NULL
UNION ALL
SELECT CTE.[Level] + 1 ,T1.PNLId,T1.PNLParentId,T1.PNLName
FROM [dbo].[DimPNL] AS T1
INNER JOIN CTE
ON T1.PNLParentId = CTE.PNLId
)
-- order the results into a #temp table
SELECT *
INTO ##temp
FROM CTE
ORDER BY level desc
DECLARE #PNLName As varchar(MAX)
DECLARE db_cursor CURSOR FOR
SELECT PNLName
FROM ##temp
OPEN db_cursor
FETCH NEXT FROM db_cursor INTO #PNLName
WHILE ##FETCH_STATUS = 0
BEGIN
INSERT INTO dbo.[test1]//from here I have a problem
Exec dbo.[spGetResult] #PNLName
FETCH NEXT FROM db_cursor INTO #PNLName
END
CLOSE db_cursor
DEALLOCATE db_cursor
I always get
stored procedure an insert exec statement cannot be nested
I have a look here But I didn't understand very much how to resolve the problem ?

Answer 1

Your best bet is to rewrite the stored procedure to a table function. Performance-wise an inline function works best, but it's usually more difficult to functionally rewrite a procedure like this.
Most stored procs can easily be rewritten to a table valued function though.
Take a look here for more info: http://technet.microsoft.com/en-us/library/ms187650(v=sql.105).aspx
Once you've rewritten it, you can nest the insert into/select statements.
INSERT INTO [TABLE] (col1, col2, ...) SELECT tvfcol1, tvfcol2, ...
from dbo.func_TVF_blabla(#param1, #param2, ...)
