存储过程变量如何引用

[Ammy_Jiang]

在create table v_ADMIN_TAB as select * from POI_CHINA where poi_province = v_PROVINCE_ID order by display desc; 中，红色字 v_ADMIN_TAB 是变量，不知道在此语句中该如何引用？
请高手指点，谢谢！

BEGIN

  DECLARE v_PROVINCE_ID varchar(100);
  DECLARE v_ADMIN_TAB varchar(100);
  
  DECLARE cur_poi_name CURSOR FOR
         SELECT PROVINCE_ID,POI_ADMIN_TAB FROM PROVINCE_NAME;
  OPEN cur_poi_name;
  cursor_loop:LOOP 
       FETCH cur_poi_name INTO v_PROVINCE_ID,v_ADMIN_TAB;
       #使用fetch到的值创建多个表
       create table v_ADMIN_TAB as select * from POI_CHINA where poi_province = v_PROVINCE_ID order by display desc;  #v_ADMIN_TAB 为变量，不知该如何引用
         
  END LOOP cursor_loop;
  CLOSE cur_poi_name;

END

set @asql=concat('create table ',v_ADMIN_TAB,' as select * from POI_CHINA where poi_province = v_PROVINCE_ID order by display desc');
prepare dd from @asql;
execute dd;

这需要动态执行该语句..
create table v_ADMIN_TAB as select * from POI_CHINA where poi_province = v_PROVINCE_ID order by display desc;
改成

set @str=concat('create table ',v_ADMIN_TAB,' as select * from POI_CHINA where poi_province = v_PROVINCE_ID order by display desc;');
prepare dmt from @str;
execute dmt; 

、试试~

动态语句使用prepare / execute /
