Just trial and error ?
I don't think its a very good solution. Then you have to figure out
exactly which error it is and which column caused the violation. (How ? By
parsing the error string ???)
And if the correct error was returned you retry the query... But how many
times ? Just once ? or a 1000 times ?
I'm sorry but I think this solution is just a Q&D hack.
