Transferred from Sourceforge:
updateSQL ignores precondition & generate SQL even though PreCondition fails. I am having this issue with postgresql database
Patch to add the onUpdateSQL attribute to the <preConditions> element, using RUN | FAIL | IGNORE as options, and changes in the code to use it.
I have committed this patch to the 1.9 branch.
Recategorizing it as feature enhancement. Will apply patch to 2.0 after bugs are worked out.
Added onOutputSql attribute to preconditions tag
