I have this query: (1 result)
SELECT idSpecie,nome FROM specienomi
WHERE idspecie=37026 and nome='X Agropogon littoralis (Sm.) C.E. Hubb.';
idspecie | nome
----------+-----------------------------------------
37026 | X Agropogon littoralis (Sm.) C.E. Hubb.
The same query but without one condition: no results.
SELECT idSpecie,nome FROM specienomi
WHERE nome='X Agropogon littoralis (Sm.) C.E. Hubb.';
idspecie | nome
----------+------
(0 rows)
I can't figure why, can someone tell me how investigate?
specienomi is a view
idSpecie is a numeric field (the key of another table)
nome is a text field generated by a custom C function (using 18 fields
(1 enumerate type, 1 boolean, 16 text).
The problem arises only with particular records, when the first
character of the string is generated by my function [1].
When the first character is copied from postgres parameter [2] all works
fine.
[1] buffer[0]='X'; buffer[1]=' ';
[2] memcpy(buffer,VARDATA(part),VARSIZE(part)-VARHDRSZ)
Thank you
Edoardo
