declare 变量名 类型 可选类型 --跟建表差不多
create procedurep()begin
declare age int default(18);declare number int default 1;select age+number;end$/*mysql> create procedure p()
-> begin
-> declare age int default(18);
-> declare number int default 1;
-> select age+number;
-> end$
Query OK, 0 rows affected (0.00 sec)
mysql> call p$
+------------+
| age+number |
+------------+
| 19 |
+------------+
1 row in set (0.00 sec)
Query OK, 0 rows affected (0.01 sec)*/#储存过程 中， 变量可以运算
#运算结果赋修值给变量用:set age :=运算式
#set age := age + 2
#参数传递
mysql> create procedure p2(number int, age int)-> begin
-> select age+number;-> end$
Query OK,0 rows affected (0.00sec)
mysql> call p2(1,2)$+------------+
| age+number |
+------------+
| 3 |
+------------+
1 row in set (0.00sec)
Query OK,0 rows affected (0.01sec)
