MySQL内部连接查询给出错误

Question

我有两张表 - char_items和items。 item_id是两个表中的公共字段。

我想从＆＃39; char_items＆＃39;中读取item_id表格并用于从“＆...”项目中获取其他信息。基于该item_id的表。但我的查询在MySQL中显示为不正确。请帮忙 -

SELECT * FROM `char_items` WHERE char_id=$char_id && isSlotted=1 INNER JOIN `items` ON char_items.item_id=items.item_id

我一直收到消息：

#1064 - 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 'INNER JOIN `items` ON char_items.item_id=items.item_id

LIMIT 0,30＆＃39;在第1行

Answer 1

联接需要在where子句

之前发生

SELECT * 
  FROM char_items c
 INNER 
  JOIN items i
    ON c.item_id = i.item_id
 WHERE char_id = $char_id 
   AND isSlotted = 1 

Answer 2

应该在join子句之后，如下所示。

SELECT * FROM `char_items` INNER JOIN `items` ON char_items.item_id=items.item_id WHERE char_id=$char_id && isSlotted=1;
