>I guess it's the shortest way but I never change SET EXACT in my programs because i got burned by it very badly a long time ago. <s>

In our case, it's for a Web framework. So, at first, for every transaction, we issue SET DELETE ON and SET EXACT OFF. We found that 4 times in one year, SET DELETE has been turned off just like that. We also add SET EXACT OFF here in case something would happen. By that, every new transaction is ok with those settings. But, again, I don't like it. :)
