Concurrency error when deleteing or updating multiple primary key fields

They are structurally similar to the table on which the trigger is defined, that is, the table on which the user action is attempted, and hold the old values or new values of the rows that may be changed by the user action.

For example, to retrieve all values in the deleted table, use: I haven't tested it, but logically it looks like it should dp what you're after...rather than deleting the inserted data, prevent the insertion completely, thus not requiring you to have to undo the insert.

It should perform better and should therefore ultimately handle a higher load with more ease.

Edit: Of course, there the potential that if the insert happened inside of an otherwise valid transaction that the wole transaction could be rolled back so you would need to take that scenario into account and determine if the insertion of an invalid data row would constitute a completely invalid transaction...

Truly nasty for performance, but if you can't let the insert fail, it does work.In the specific case in the question, it is not really a problem, because the result is to delete the record, which won't refire this particular trigger, but in general that could be a valid approach. The code for your trigger that could be used in this way would be: every 1 second or so.While you're at it, how about writing a nice little SP to stop the programming folk from inserting errors into your table.Recursive triggers are off by default, and there's no talk of a limit - but frankly, I've never turned them on, so I don't know what happens with the inevitable stack overflow.I suspect MSSQL would just kill your spid (or there is a recursive limit).

One option would be for the trigger to roll back the transaction.
