今晚我最得意之作——利用Oracle超级无敌强大函数生成“批量生成数据语句”！

语句一：

 

select rownum, a.*
  from (select t.brand_name, wm_concat(t.pd_type), wm_concat(t.brand_id)
          from base_brand t
         group by t.brand_name) a

语句二：

select 'insert into BASE_BRAND_INFO(BRAND_ID, BRAND_NAME, BRAND_NAME_CN) values(' ||
       rownum || ',''' || a.brand_name || ''',''' || a.brand_name || ''');'
  from (select t.brand_name, wm_concat(t.pd_type), wm_concat(t.brand_id)
          from base_brand t
         group by t.brand_name) a

语句三：

 

select 'update BASE_BRAND set BRAND_ID=' || rownum || ' where BRAND_ID in (' || a.BRAND_IDS || ');'
  from (select t.brand_name, wm_concat(t.pd_type), wm_concat(t.brand_id) BRAND_IDS
          from base_brand t
         group by t.brand_name) a

最后：

 

准确！高效！简单！完美！
