SELECT DISTINCT g.* FROM epms_group g LEFT JOIN epms_member m ON m.saas_group_id = g.saas_group_Id LEFT JOIN epms_visit_country v ON v.saas_group_id = g.saas_group_Id WHERE 1 = 1 <if test="status !=null and status != ''"> and g.status in #{status} </if> order by create_date desc 前端传到后端的状态是多个 比如一,二,三,四, 这里的sql该怎么写

你的 SQL 可以这样写：

SELECT DISTINCT g.*
FROM epms_group g
LEFT JOIN epms_member m ON m.saas_group_id = g.saas_group_Id
LEFT JOIN epms_visit_country v ON v.saas_group_id = g.saas_group_Id
WHERE 1 = 1
  AND g.status IN (
    <foreach collection="status.split(',')" item="item" separator=",">
      #{item}
    </foreach>
  )
ORDER BY create_date DESC

这里使用了 MyBatis 的 foreach 标签，将前端传递过来的状态字符串按照逗号分隔为多个参数，然后在 SQL 中进行 IN 查询。
