Concurrency error when deleteing or updating multiple primary key fields datingfriends1 com

I've got a table, some Table, and I'm trying to prevent people from inserting bad records.For the purpose of this question, a bad record has a field "some Field" that is all numeric.

Truly nasty for performance, but if you can't let the insert fail, it does work.Having a system intelligently decide whether to allow such updates is computationally intractable, essentially a variation on the halting problem.The accepted solution to this is not to permit the trigger to alter the changing data, although it can roll back the transaction.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...
