  • oracel中将子表中一个字段多条数据合并到主表的sql

    select f.* ,g.nsjgName, h.XCJZZZZ, h.XCJFZZZ
      from (select max(t.JGSY_NAMEs) JGSY_NAMEs,
                   max(t.jgsy_gg) jgsy_gg,
                   jgsy_code,
                   sum(t.zcjzs) zcjzs,
                   sum(t.fcjzs) fcjzs,
                   listagg(t.pzwh, ',') within group(order by t.jgsy_code) pzwh,
                   listagg(t.BEIZHU, ',') within group(order by t.jgsy_code) beizhu
              from s_zsys t
             where t.BLRESULT = '3'
               and substr(t.jgsy_code, 0, 6) = '320100'
             group by jgsy_code
             order by t.jgsy_code) f
      left join (select jgsy_parent_code,
                        listagg(jgsy_name, ',') within group(order by gen.jgsy_parent_code) nsjgName
                   from jgsy_common gen
                  where 1 = 1
                    and gen.jgsy_type = '06'
                  group by jgsy_parent_code) g
        on g.jgsy_parent_code = f.jgsy_code
      left join BMLDZS h
        on h.jgsy_code = f.jgsy_code;

    --select * from jgsy_common f where f.jgsy_parent_code='320100-01-10012' and f.jgsy_type='06'


    注意用这个函数可以知道那个是统计列【grouping函数】
    select max(code) code,case when grouping (code) = 1 then '0'  end  orders,max(name) name,
