mysql FIND_IN_SET 用法

mysql 中 FIND_IN_SET  是判断某个字符串是否在带逗号的字符串中

例如 

SELECT
  t.group_id,
  COUNT(group_id)    tsum
FROM (SELECT
        group_id
      FROM xx
      WHERE FIND_IN_SET(openid,'qqqwqnfocFq5IL2sXB2Qu0I,oarwerrr-2KRah_TklJEomljhlKg,oaSiouEgtr5t5utLFU8-evmkn5BwQ3_c')
          AND user_uuid = 'xxxxxxxxxxxx') t
GROUP BY group_id;

后者是带逗号的字符
