QSqlQuery, MySQL, "show engines;"

[mbaszczewski]

Hi I have problem with simple query: "show engines;".

QSqlQuery query(database);
query.exec("show engines;"); 
query.size() //always -1 !!
//for "show collation;" everything is ok

QSqlQuery query(database);
query.exec("show engines;"); 
query.size() //always -1 !!
//for "show collation;" everything is ok

To copy to clipboard, switch view to plain text mode 

This is strange because this query work's fine with MySQL Query Browser or phpMyAdmin. Any idea?
