mysql - 选择 WHERE 子句，拆分列值并检查

Question

我有以下表架构

id   name     type
1    ABC      1,2,3,4
2    PQR      2,3,5 
3    XYZ      1,4
4    TCS      3,1
5    PPP      2,3

这里我想要如下显示结果，即类型为 1 和 4。
结果:-

id   name     type
1    ABC      1,2,3,4
3    XYZ      1,4
4    TCS      3,1

Answer 1

您可以使用FIND_IN_SET()功能:

Returns a value in the range of 1 to N if the string str is in the string list strlist consisting of N substrings. A string list is a string composed of substrings separated by “,” characters.
Returns 0 if str is not in strlist or if strlist is the empty string.

SELECT * FROM Table1
WHERE
     FIND_IN_SET(1, type)
  OR FIND_IN_SET(4, type)

输出:

╔════╦══════╦═════════╗
║ ID ║ NAME ║  TYPE   ║
╠════╬══════╬═════════╣
║  1 ║ ABC  ║ 1,2,3,4 ║
║  3 ║ XYZ  ║ 1,4     ║
║  4 ║ TCS  ║ 3,1     ║
╚════╩══════╩═════════╝
