| hello....i have a need for an insert trigger...to explicitly update one of table columns regardless if a value has already been passed through during the actual insert operation.the problem i am running into is that there is an primary key ID column, but it is not an Identity data type(i have done this before using the @@IDENTITY function to retrieve the current value)....so I need to figure out how, within my trigger, I can capture the pk id value for the row that is being INSERTed and then do my update based on that pk id. thanks -dw |

You need to use the INSERTED table. Read BOL if you don't know what that is.The @@IDENTITY doesn't work anyway, even if you had an identity column, because you could have inserted more than one row. You have to write a trigger to allow for all cases.This code should do it:update myTableset Col_1 = YourNewValuefrom myTable join inserted on myTable.PK = inserted.PK quote:

| Thanks! That worked great. I completely forgot about the INSERTED table. - dw |
