mysql检查数字是否在逗号分隔的列表中 [英] mysql check if numbers are in a comma separated list

问题描述

我有一个这样的表:

UID(int) NUMBERS(blob)
----------------------
1        1,13,15,20
2        3,10,15,20
3        3,15

我想测试3和15是否在称为NUMBERS的Blob中.并可以看到无法使用LIKE %%

And I would like to test if 3 and 15 are in the blob called NUMBERS. And can see the LIKE %% cannot be used

仅选择ID为2和三个scoulb的行...

Only row with ID 2 and three scoulb be selected...

推荐答案

此方法也适用:

SELECT * FROM table WHERE 3 IN (NUMBERS) AND 15 IN (NUMBERS)

使用IN将查找以逗号分隔的字符串，例如.这两个

using the IN will look into a comma separated string eg. these two

WHERE banana IN ('apple', 'banana', 'coconut')
WHERE 3 IN (2,3,6,8,90)
