Subject Fw: [IBO] Strange behavior of TIBOQuery.Locate method
Author Fernando Deola
Well, after a long wait, it seems that we are in the right way...

The newest release solved the problem with the refreshing of the detail
records, but, using the FIRST clause leads to an error (token unknown line 1
char 14 ID_MEMBER) in the query below:

SELECT FIRST 1 M.ID_MEMBER
FROM
PERSON P
INNER JOIN MEMBER M
ON (M.ID_PERSON = P.ID_PERSON)

ORDER BY
P.SN_PERSON, P.NM_PERSON

Keylinks is ID_MEMBER.

The monitor shows a weird construction of the SQL: SELECT FIRST ID_MEMBER
FROM ... ???

If I set KeylinksAutoDefine to true or remove the FIRST clause, the problem
is gone.

About the related situation in my post of February 26, 2003, I didn't test
with this new release, sorry (I had to do the same thing with a new
approach), but I really want to know more about your suggestion of using the
NOCASE feature with OrderingItems/OrderingLinks for my order by. I simply
don't use OrderingLinks as I supposed they were useful mainly to take
advantage of some features of the TIB_ components (Am I right?).

Thanks,
