php的pdo中对双引号做了什么处理么,为什么这个语句可以执行通过

本帖最后由 pakey 于 2015-06-21 14:19:06 编辑 找了个轻量级的数据库类 medoo,感觉不错,但是使用时发现了一个很奇怪的问题
在使用mysql的时候他组装的sql表名、字段名都是用双引号的,这样生成的语句不能直接执行
mysql> SELECT * FROM "dd_xq_user_info" WHERE "uid" = '1' AND "status" = '1' ORDER BY "id" LIMIT 1;<br />ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '"dd_xq_user_info" WHERE "uid" = '1' AND "status" = '1' ORDER BY "id" LIMIT 1' at line 1<br />
Copy after login

但是用pdo执行这个语句执行成功了,而且没有错误,请问大家这个是为什么呢?pdo做了什么处理?
------解决思路----------------------
SQL_MODE 的默认值是 STRICT_TRANS_TABLES,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION
改成 ANSI_QUOTES 后,如果没有其他的操作,自然是不会有影响的
