To recreate the auto increment key: If you can go to table - design - set Identity Specification (or Identity for SQL Sever 2000) to Yes.
Also, if you need to reset the identity value of the table: DBCC CHECKIDENT can reseed (reset) the identity value of the table. For example, YourTable has 25 rows with 25 as last identity. If we want next record to have identity as 35 we need to run following T SQL script in Query Analyzer. DBCC CHECKIDENT (yourtable, reseed, 34) Hope this helps.

To: "sql" <[email protected]> Date: Thursday, April 23, 2009, 9:10 AM Hi: I have a customer whose programmer has vanished and he is trying to get his application back on line. I'm an intermediate CF programmer and I've managed to get everything working again except for one problem. His database is hosted - and somehow, when he restored his application, the fields in his database lost their autonumbering capability. I tried creating the next number right before the insert by getting the max value of the field and then adding 1 to it, and that works for the most part, but occassionally, we are seeing the old "Violation of PRIMARY KEY constraint 'PK_TblTestAnswers'. Cannot insert duplicate key in object 'dbo.TblTestAnswers' - and I can't figure out why unless to users are somehow hitting the same page at exactly the same time and clicking submit. So the only thing I can think of to fix the problem is to recreate the autoincrment key fields somehow. Does anyone have any Coldfusion code to insert a new autoincrement key field in to a MS SQL table and then remove the old one? Or is there a way to modify a key field to autoincrement?
