'Illegal mix of collations' with PHP 4.3.10 and MySQL 4.1.7

I have noticed a very peculiar behavior when I upgraded my PHP revision from 4.3.9 to 4.3.10 (I use Debian Linux). Suddenly, the PHP MySQL client stopped accepting the default encoding / collation when connecting to the server. When issuing any query containing text field comparisons, I get the following error message: Illegal mix of collations (latin2_general_ci,IMPLICIT) and (latin1_swedish_ci,COERCIBLE) for operation '=' The appropriate values when using mysqladmin to check the variables are as follows: | character_set_client | latin2 | character_set_connection | latin2 | character_set_database | latin2 | character_set_results | latin2 | character_set_server | latin2 | collation_connection | latin2_general_ci | collation_database | latin2_general_ci | collation_server | latin2_general_ci All the tables are converted to the latin2 charset, all the relevant columns have "latin2_general_ci" set as the default collation. The following entry in the my.cnf file also doesn't help: [client] character_set = latin2 The webserver is set to use ISO-8859-2 (latin2) as the base charset: AddDefaultCharset iso-8859-2 The appropriate php packages are version 4.3.10-1 from dotdeb.org. The libmysqlclient package is version 4.1.7-1 from the same source. Same goes for the mysql-server package. This problem has appeared only when migrating from PHP 4.3.9 to 4.3.10, before that everything worked fine. I have partially remedied the problem by putting the 3 queries: set names latin2; set character set latin2; set collation_connection='latin2_general_ci'; after the initializing code of every MySQL connection I make. However, since I host multiple sites on the server and possibly have multiple PHP applications that use SQL client connections, I cannot use this as a final solution. Downgrading is also not a good option because I cannot find the old .deb packages anywhere (besides, it might be caused by some bizarre change done to the configuration file by the 4.3.10 preinstall script, but I've done a quite thorough search through the config files and found naught). Do you perhaps know how would I be able to 'force' the PHP MySQL client to accept the latin2 encoding as default? -- Greetings, Piotr Wilkin pwl@druid.com.pl PGP key: http://pwl.yz.pl/pwlpgp.txt
