I'm trying to insert records to a table with identity column. I first set it to on and try to insert which fails with the error
cannot explicitly insert identity. This was within a stored proc and I thought I needed a "go" statement and have learnt that I cannot use a "GO" within a stored proc. Try to execute the "Set identity_insert tablename on GO" using exec() function and got an error.
The syntax is not an issue here, I can execute the insert statement successfully without inserting identity. The problem is when I want to insert identity.
Thanks in advance,
Thulani

You can use that in your stored proc withOUT the need for a GO or dynamic sql. Just make sure to set it off again before you exit.

--edit correction thanks to Phil.

Like this:

create table InsertTest

(

ID int identity not null,

SomeValue varchar(10)

)

go

create procedure IdentityTest

as begin

set identity_insert InsertTest on

insert InsertTest (ID, SomeValue) Values (10, 'MyValue')

set identity_insert InsertTest on

end

go

exec IdentityTest

select * from InsertTest

For real code you should put this inside a try catch.

Thanks for prompt response. The issue here is, the identity_insert is ignored thus the error. Even if I run it on ssms.

Thanks everyone. The problem is sorted. I had two databases and was trying to move data across. I was setting Identity_isert on for the current database instead of the destination database.
