mysql：批量插入不同的UUID

INSERT INTO t_base_role_resource_ref (refID, roleID, resID, orgID, belongTo)

SELECT uuid() AS refID, t1.roleID, t1.resID, '1' AS orgID, 'school' AS belongTo

FROM t_base_role_resource_ref t1

WHERE t1.belongTo = 'school-default'
     AND NOT EXISTS (
         SELECT 1
         FROM t_base_role_resource_ref t2
         WHERE t2.roleID = t1.roleID
             AND t1.resID = t2.resID
             AND t2.orgID = #{schoolID}
     );

UPDATE t_base_role_resource_ref

SET refID = replace(refID, '-', '')

WHERE orgID = #{schoolID};

注意：第一个select时不能直接用replace语句进行替换，否则生成的是同样的UUID，必须先插入后更新。

生成的UUID非常接近，乍一看是一样的。
