RashdSiddique:
Use "Select MAX('coloumnname') from tablename"
This Might help to do the trick.
Happy Programming ;-)

Thanks for the solution.
But i have used your solution.Problem is if any of the row is deleted from the database then it will not give the last identity value inserted.

This gives wrong results if multiple users inserts data at a time.

Solution 2

But it works for me

"SELECT IDENT_CURRENT('Orders')

Ok , Have you tried this SELECT MAX(ID) FROM Orders if id is the identitiy column

No it will give you . Have you tried with the delete scenario ? Let say for example in Orders table there are id 1,2,3,4,5 then above query will return (5) and if row with id 3 got deleted then also above query will return (5)

Plz check that you are using MAX() function not COUNT() function.

Solution 5

use the following statement :

SQL

DBCC CHECKIDENT (‘tablename’, NORESEED)

it works directly in sql server but not sure if it'll work from C#
