SQLException when using mysql and vibe-d 0.8.0

[Samael]

I'm not yet sure of the cause but there seems to be a problem with the mysql driver.

the error occured in this try/catch block:

    override ddbc.core.ResultSet executeQuery() {
        checkClosed();

            Prepared p = prepare(conn.getConnection(), to!string(cmd.sql));
            rs = p.querySet();
            resultSet = new MySQLResultSet(this, rs, getMetaData());
            return resultSet;
        } catch (Throwable e) {
            throw new SQLException(e);
        }
    }

I've replicated this in testddbc.d by adding an extra test for prepared statements (it doesn't make a differnece if using vibe-d 0.7.31 or 0.8.0).

I'll look into it further after kids go to bed.
