--删除 drop procedure if exists up_common_select --创建 CREATE PROCEDURE `up_common_select` ( in t_name varchar(50) ) begin declare v_sql varchar(500); set v_sql= concat('select * from ',t_name); select v_sql; --注意:prepare(预处理)execute stmt using @var,只能跟@var变量,declare和传入的变量不行!!! set @v_sql=v_sql; prepare stmt from @v_sql; EXECUTE stmt ; deallocate prepare stmt; end; --调用 call up_common_select('admin_authority');
