Hi Dawn, This is something which should be handled by the database. In a database where you have auto incrementing the primary keys it shouldn't be the applications responsibility to keep an eye on that, you should be doing simple INSERT statements and allowing the DB to do the work.
In a SQL Server database, provided you're using SQL Server Management Studio to connect to the DB you can set the column to auto-increment by right clicking the table in the object explorer and choosing 'modify' or 'edit' then highlight the PK column and in the 'column properties' pane at the bottom expand the 'identity specification' section, you'll then be able to set the column to an identity and have it auto increment. Hope that helps, Rob -----Original Message----- From: Dawn Sekel [mailto:dse...@ciber.com] Sent: 23 April 2009 17:26 To: cf-talk Subject: CF Code to create AutoIncrement column MS SQL? 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?
