Subject [jira] Commented: (DERBY-2888) Useless error message during import: Invalid character string format for type INTEGER.
Date Thu, 16 Aug 2007 20:15:31 GMT

Bryan Pendleton commented on DERBY-2888:
----------------------------------------

What I've done in the past is to use a binary search technique:
- remove half the rows in your input file and see if the problem still occurs
- if it does, remove another half of the remaining rows
- if it doesn't, discard this half of the rows and switch to the other half of the rows

You may have to conduct a few dozen experiments, but you'll find the bad row.

I agree, by the way, that including the actual row and column where the exception occurred
would be extremely helpful. If I get some time this weekend, I'll have a look at that code.
