Hi, >Judging by your second comment, would you consider this bug closed? No, since the GENERATE_UNIQUE() function, which relies on a FOR BIT DATA field still won't work. It seems to be the FOR BIT DATA variants of the CHAR fields that PHP has problems with, and even though I haven't bumped into more situations where I need this, It sure will happen at some point - I can imagine I'll encounter the problem when we next month start to store product pictures in the database. A such field type would be convenient to use, as an alternative to xLOB fields..
