Re: Insert only if not found

I think i spoke to soon. It works. But if i change a letter from capital to
simple it inserts my record 2 times. So i have 2 records for "Shavonne" and
"shavonne". So i thought i would do the select in uppercase.

INSERT INTO MOD48_02 (ID, TE_INDI, TE_COGNOME, TE_NOME, TE_SESSO,
TE_ATTNASC, TE_LUONASC, TE_DTNASC, TE_PROVSTATO, TE_PROV, TE_PATERNITA,
TE_RICHIESTA, USERNAME, DATE_INSERTED, TIME_INSERTED) SELECT
'127001200745114035', '', 'chan', 'micia', 'F', '', '', '01/05/2006', '',
'', '', '', 'demo', '05/04/2007', '11.40.35' WHERE NOT EXISTS (SELECT
upper(TE_COGNOME), upper(TE_NOME), upper(TE_SESSO), TE_DTNASC FROM MOD48_02
WHERE TE_COGNOME='CHAN' AND TE_NOME='MICIA' AND TE_SESSO='F' AND
TE_DTNASC='01/05/2006');

but this doesn't work. I don't know why. If i try only the part

SELECT upper(TE_COGNOME), upper(TE_NOME), upper(TE_SESSO), TE_DTNASC FROM
MOD48_02

it returns me the fields in UPPERCASE. It's really strange why it doens't
work all together.

Anyone?
