mysql施用什么语言编写循环，选择和函数_Sql Server

mysql使用什么语言编写循环，选择和函数？
oracle对应pl/sql,sqlserver对应t-sql，
mysql有类似的语言吗，可以实现像上述2种数据库
的循环，选择和函数等等的语句结构吗？

SQL code

mysql> create procedure pro10()    -> begin    -> declare i int;    -> set i=0;    -> while i<5 do    ->     insert into t1(filed) values(i);    ->     set i=i+1;    -> end while;    -> end;//Query OK, 0 rows affected (0.00 sec)
