When a stored proc I've created is executed from within my app (Delphi 7,
using FIB components), I

get the err msg:



The insert failed because a column definition includes validation
constraints.validation error for

column ADV_DIR, value "".



The ADV_DIR column, a VarChar(7), does not contain a constraint--the only
constraint on the entire

table is the PK. Adv_Dir is nullable, and the value being rejected is an
empty string.



What could be causing this? Many other empty VarChar values, which are the
same except for varying

specified lengths, precede the assignment of this value without complaint.
