More than 34 changes?
Hi all,
I just observed a TABLEUPDATE() behavior that suprised me.
If a form has more than 36 controls and user edits 35 control values, TABLEUPDATE() fails. Using AERROR() the message "SQL String too long..." is reported.
If user changes 1-34 controls or changes all controls, TABLEUPDATE() will work. Appending a blank record seems to be immune to the limit/TABLEUPDATE() failure.
Evidently, VFP creates an SQL select... statement containing a list of all modified fields and this exceeds the 255 char string limit for SQL statements. (I think it's 255).
Has anyone else observed this? Is there a way to commit changes without forcing with TABLEUPDATE(0,.t.)? I suppose a loop that finds all CURVAL() = OLDVAL() true and then forces a TABLEUPDATE would be a workaround. That doesn't seem too "elegant" tho.
TIA,
Bill
