如何在mysql中排除结果

Question

我有这个SQL查询。其中我不想选择Type不等于1的记录。这个查询有什么问题？

SELECT * 
FROM admin_table
WHERE Type !=  '1'
AND Uneym LIKE  '%'
OR Email LIKE  '%'
LIMIT 0 , 30

Answer 1

你必须在where括号中包含where条件：

where `type` <> 1 and (`uneym` like '%%' or `email` like '%%')

Answer 2

SELECT * 
FROM admin_table
WHERE Type <>  '1'
AND Uneym LIKE  '%'
OR Email LIKE  '%'
LIMIT 0 , 30

Answer 3

SELECT * 
FROM admin_table
WHERE NOT Type =  '1'
AND (Uneym LIKE  '%' OR Email LIKE  '%')
LIMIT 0 , 30

Answer 4

一句话你不需要条件

AND Uneym LIKE  '%'
OR Email LIKE  '%'

因为它说给我带来了所有

 Type !=  1

或

 Type <>  1

无关紧要，both syntax work
