Question

我从未使用过这样的PHP / MYSQL技巧来加入multitables。请谁有此领域的经验帮助：

$qry=mysql_query("select {$table_prefix}user_cv.*, {$table_prefix}advertising.* from {$table_prefix}user_cv, {$table_prefix}advertising where {$table_prefix}user_cv.publish='yes' and {$table_prefix}advertising.publish='Y'");

mysql查询返回0结果。

Answer 1

$qry = "SELECT {$table_prefix}user_cv.*, {$table_prefix}advertising.*
        FROM {$table_prefix}user_cv
        LEFT JOIN {$table_prefix}advertising ON {$table_prefix}advertising.publish='Y'
        WHERE {$table_prefix}user_cv.publish='yes'";
mysql_query($qry);

我没试过这个！我可能错了，但这可能是朝着正确方向迈出的一步。（还是新的自己）
