I think that you don't have to write a conversion program because MySQL

Hello,
I have upgraded MySQL from 4.0.7 to 4.1.9 (OS Win XP SP2) and now I have a
problem with empty string comparison.
Test case:
CREATE TABLE tb_test (
t1 char(5) NOT NULL default '',
t2 char(5) NOT NULL default ''
) ENGINE=MyISAM DEFAULT CHARSET=cp1250 COLLATE=cp1250_czech_cs;
INSERT IN
I finally found the solution.
It's possible to set everything in MySQL ODBC/Connector on tab Connect
options. I had to write to the field Initial Statement statement SET NAMES
'wanted_character_set' and that solved the problem.
