I am using SCOPE_IDENTITY() to get last generated id in session,scope.
but this is giving me values for all execution at once. I am using it in sp and that is causing some integrity constraint violation . it can be fixed if SCOPE_IDENTITY() give me only one value.
my scenario
.......
WHILE @@FETCH_STATUS = 0
BEGIN
insert into table T1
values ();
SELECT @PageIdIndt = SCOPE_IDENTITY(); --- e.g. it gives 121,123,124
Insert into table T2
values();
SELECT @PageIdIndt_two = SCOPE_IDENTITY();-- its expected values is 321, but it is giving 121,123,321,124
insert into table T3 (col,col2,col3)
values(val1,val2,@PageIdIndt_two);
.......

Really hard to give advice based on incomplete code snippits. I would look at using the OUTPUT clause and table variable(s) to pass information as well as looking at eliminating the use of a cursor. Of cousre, can't give you a full answer with all the necessary information to do so.

Please read the first article I reference below in my signature block regarding what and how to post the relevant information.

SCOPE_IDENTITY cannot be returning multiple values. It doesn't work like that. The return type is numeric(38,0).

As Lynn said, if you can provide some details we can provide some help.

Yeah i thought something looked wrong, when he said it's returning 4 values;

ii had to double check myself and test scope identity to prove it returns one and only one value.

i think that was psuedocode to represent mulitple values inside a *muttering quietly* cursor

CREATE TABLE MYADDRESSES(

EMPNO INT IDENTITY(1,1) PRIMARY KEY,

ENAME VARCHAR(100),

ADDR1 VARCHAR(100),

ADDR2 VARCHAR(100),

CITY VARCHAR(100),

STATECODE VARCHAR(2),

ZIPCODE VARCHAR(100),

PHONE VARCHAR(20),

MOREDATA VARCHAR(100))

--insert some test data

INSERT INTO MYADDRESSES( ENAME, ADDR1, ADDR2, CITY, STATECODE, ZIPCODE, PHONE, MOREDATA)

SELECT 'Kalvin','123 My Imagination St','','Miami','FL','33024','555-1212','likes snowmen'

UNION

SELECT 'Hobbes','123 My Imagination St','','Miami','FL','33024','555-1222','likes to tease calvin'

select SCOPE_IDENTITY()
