RE: verify db with mysql

Hi list,

I'm in the process of adding write support to postfix's mysql client (you will
find a patch against postfix-2.7.1 in the appendix). But I have two problems:
1) the dict_cache_clean_event writes _LAST_CACHE_CLEANUP_COMPLETED_ to the
database. Is this the intended behaviour?

2) If I'm guessing right then the dict_cache_clean_event will iterate with
help of dict->sequence through the database and will look for keys to expire.
But I don't know how to implement this iteration/traverse process with mysql.
My first thought was to use "SELECT * FROM verify" and mysql_use_result() but
I'm wondering if there is a better solution.
Has anyone an idea of how to do this?

Thanks for your help and best regards
