选择多个表时使用多个LIKE

Question

我在选择多个表时尝试使用多个LIKE。我的SQL查询如下。

SELECT users.*, threads.* 
FROM users, threads 
WHERE users.Username LIKE ? 
OR threads.Name LIKE ?

然而，如果我只有一个LIKE，就像这样......

SELECT users.*, threads.* 
FROM users, threads 
WHERE users.Username LIKE ?

我应该如何多次使用LIKE？

Answer 1

尝试此查询：

SELECT users.*, threads.* FROM users, threads WHERE (users.Username LIKE ? OR threads.Name LIKE ?)

Answer 2

检查下面的查询，我试过下面的例子。它对我来说很好，

SELECT users.*, threads.* 
FROM users, threads 
WHERE users.Username LIKE '?' 
OR threads.Name LIKE '?'

例如

select p.name,bi.mrp 
from billitem bi,product p 
where p.name like 'a%' 
or bi.productname like 'ta%'
