  • 0

Is it possible to force a column in a SQL Server 2005 table to a certain value regardless of the value used in an insert or update statement is? Basically, there is a bug in an application that I don’t have access to that is trying to insert a date of 1/1/0001 into a datetime column. This is producing a SqlDateTime overflow exception. Since this column isn’t even used for anything, I’d like to somehow update the constraints on the columns or something in the database to avoid the error. This is obviously just a temporary emergency patch to avoid the problem… Ideas welcome…

  1. If it is a third party application then I will assume you don’t have access to the Stored Procedure, or logic used to generate and insert that value (it is still worth checking the SPs for the application’s database though, to see if you can modify them).

    As Charles suggested, if you don’t have access to the source, then you need to have a trigger on the insert.

    The Microsoft article here will give you some in depth information on creating triggers.

    However, SQL Server doesn’t have a true ‘before insert’ trigger (to my knowledge), so you need to try INSTEAD OF. Have a look here for more information. In that article, pay particular note of section 37.7, and the following example (again from that article):

    CREATE TRIGGER T_InsertInventory ON CurrentInventory INSTEAD OF INSERT AS BEGIN INSERT INTO Inventory (PartNumber, Description, QtyOnOrder, QtyInStock) SELECT PartNumber, Description, QtyOnOrder, QtyInStock FROM inserted END

    Nick.
