struct sql_db *db = sql_init("mysql", "host=localhost");
struct sql_transaction_context *trans = sql_transaction_begin(db);
sql_update(trans, "INSERT INTO blah");
Plus add the necessary error handling. Also note that most Dovecot
binaries aren't linked with SQL libraries, so you need to do that too.
Another possibility could be to do this via dict proxy. See
lib-dict/dict.h and e.g. how quota-dict uses it. You can then configure
a mapping to SQL database in a similar way.
