这个查询有什么问题？

Question

这个查询：

SELECT tbl_deliverable.*, user_to_deliverable.* 
where tbl_deliverable.id = user_to_deliverable.d_id 

返回此错误从phpMyAdmin的：

#1064 - 您的SQL语法错误;请检查与您的MySQL服务器版本对应的手册，以便在第1行的'where tbl_deliverable.id = user_to_deliverable.d_id'附近使用正确的语法。

为什么？

Answer 1

你忘了你的 “从表” 中的SQL：

SELECT tbl_deliverable.*, user_to_deliverable.* 
from tbl_deliverable,  user_to_deliverable 
where tbl_deliverable.id = user_to_deliverable.d_id 

只需添加：

from tbl_deliverable, user_to_deliverable 

Answer 2

你没有FROM条款。

应该

SELECT tbl_deliverable.*, user_to_deliverable.* 
FROM tbl_deliverable, user_to_deliverable    -- <== missing 
where tbl_deliverable.id = user_to_deliverable.d_id 

或做ANSI SQL-92

SELECT tbl_deliverable.*, user_to_deliverable.* 
FROM tbl_deliverable INNER JOIN user_to_deliverable    
     ON tbl_deliverable.id = user_to_deliverable.d_id
