Rade,

it's the same problem you encountered already some weeks ago (IBO 4.7.16
wrong update SQL with alias, 05/01/2007).
At that time I have sent you a changed IBF_Query.pas. Did you get and try
it? (I asked you for a feedback but I didn't receive one.)

This version you may have was not yet correct in building the UpdateSQLs
with queries where only key fields where involved
(if I remember accurately; the right parenthesis were not set). In the
meantime I have patched this.

KeyLinks don't play any role in building the UpdateSQLs. IBO looks for key
fields (primary keys) when it generates the SQLs.

Herbert
