mysql d递归查询语法解析存在问题

[guojialin520]

String sql ="SELECT N_ID FROM(SELECT @ids AS _ids,( SELECT @ids := GROUP_CONCAT( N_ID ) FROM T_DEPARTMENT" + " WHERE FIND_IN_SET( N_PARENT_ID, @ids ) ) AS cids," + "@l := @l + 1 AS LEVEL FROM T_DEPARTMENT,( SELECT @ids :="+id+" , @l := 0 ) b WHERE @ids IS NOT NULL) ID," + "T_DEPARTMENT DATA WHERE FIND_IN_SET( DATA.N_ID, ID._ids ) "; 1：:=符号解析错误 2：是否支持原始sql语句传递，可以指定放行的sql
