Question

Hi,
    The following query is showing error An INSERT EXEC statement cannot be nested
CREATE PROCEDURE [dbo].[Procedur3]
@para1 int
AS
BEGIN
CREATE TABLE #tem
select * from detialpar where did=@para1
--this code is quite big and is called from many place so we kept it inside this SP , so that we can call the sp to get result.
END
CREATE PROCEDURE [dbo].[Procedur2]
@para1 int
@para2 datetime
AS
BEGIN
CREATE TABLE #tem
insert into #tem (value) exec [dbo].[Procedure3] @para1
exec ('select * from abc
left join #tem on id=temid
where id =' + cast(@para1 as varchar) -- i do not want to change this big dynamic query, because it has many optonal code concatinated by using "if then else".
END
CREATE PROCEDURE [dbo].[Procedure1]
@para1 int,
@para2 datetime
AS
BEGIN
delete from table1 where id=@para1
insert into table1 ( col1,col2) exec Procedure2 @para1,@para2
……. There are many blocks in this SP where we are deleting and inserting with different SP .
select Name,Amount from #Temp1
END
CREATE PROC Procedure
AS
BEGIN
SET TRANSACTION ISOLATION LEVEL SNAPSHOT
SET NOCOUNT ON
LOOP "A" starts here which gests id from a table xyz @para1
begin try
begin trans
exec [Procedure1] @para1
LOOP "A" ents here
COMMIT TRANSACTION;
END TRY
BEGIN CATCH
IF @@trancount > 0 ROLLBACK TRANSACTION;
END CATCH;
END
GO
Please tel me some good way of solving the error.
yours sincerly

Answer 1

You can not do like above:
Try the below:(Not tested), Below, we do not change the code, however, we placed your dynamic execution to different procedure.
CREATE PROCEDURE [dbo].[Procedur3]
@para1 int
AS
BEGIN
CREATE TABLE #tem
insert into #tem (value)
select * from detialpar where did=@para1
--this code is quite big and is called from many place so we kept it inside this SP , so that we can call the sp to get result.
END
CREATE PROCEDURE [dbo].[Procedur2]
@para1 int
@para2 datetime
AS
BEGIN
CREATE TABLE #tem
exec [dbo].[Procedure3] @para1
END
CREATE PROCEDURE [dbo].[Procedure1]
@para1 int,
@para2 datetime
AS
BEGIN
delete from table1 where id=@para1
insert into table1 ( col1,col2)
exec ('select * from abc
left join #tem on id=temid
where id =' + cast(@para1 as varchar) -- i do not want to change this big dynamic query, because it has many optonal code concatinated by using "if then else".
……. There are many blocks in this SP where we are deleting and inserting
with different SP .
select Name,Amount from #Temp1
END
CREATE PROC Procedure
AS
BEGIN
SET TRANSACTION ISOLATION LEVEL SNAPSHOT
SET NOCOUNT ON
LOOP "A" starts here which gests id from a table xyz @para1
begin try
begin trans
exec [Procedure1] @para1
LOOP "A" ents here
COMMIT TRANSACTION;
END TRY
BEGIN CATCH
IF @@trancount > 0 ROLLBACK TRANSACTION;
END CATCH;
END
GO
