Hello,
I have problem which I don't understand.
if I send command (from Query Browser or from C++ Builder application)
SELECT FileName FROM Files WHERE FileName = 'FILE1.TXT' OR FileName =
'FILE2.TXT'
query executes without any problem but command
SELECT FileName FROM Files WHERE FileName IN ('FILE1.TXT', 'FILE2.TXT')
throws error "illegal mix of collations for operation 'IN' "
I thought that IN is somehow by optimizer translated to ORs
Could someone explain me why first query is OK and second not? Please.
I'm using WinXP SP2 and MySQL 4.1.9-nt-log
databases and tables use CHARSET=latin2 COLLATE=latin2_czech_cs
I already read some articles about the topic in MySQL forum but they didn't
helped me much.
Thanks in advance
Dusan Pavlica
