I work in a large scale IT support environment. Twice now we have seen an invalid date of 02/31/2157 being inserted in an Oracle DATE column. So far I have not been able to reproduce this problem, but it appears to be happening occasionally when a user attempts to save ’00/00/0000′ into the column. I believe the value is originating from a PowerBuilder DataWindow update.

The application uses myriad libraries for all sorts of technologies, so this question may be a bit vague, but…

Has anyone seen the date 02/31/2157 in some established library that Oracle could be defaulting to when some other invalid date is entered? Perhaps an end-of-time concept analogous to the beginning-of-time date of 1/1/1970?

    Turns out this was a powerbuilder issue. The field was created in the datawindow as required, but was programmatically changed to be non-required before saving. So a null value was being saved to a non-null database column, and powerbuilder inserted some dummy date instead of just throwing an error.
