你可使用create procedure号召创立存储历程。语法如高 −
delimiter // CREATE PROCEDURE yourStoreProcedureName() BEGIN Declare variable here The query statement END // delimiter //
登录后复造
将上述语法运用于建立存储历程。查问如高 −
mysql> use test; Database changed mysql> delimiter // mysql> create procedure Sp_callTableStoredProcTable() −> begin −> select *from StoredProcTable; −> end // Query OK, 0 rows affected (0.54 sec)
登录后复造
Now you need to change the delimiter with ; to call stored procedure −
mysql> delimiter ;
登录后复造
You can call stored procedure using CALL co妹妹and. The syntax is as follows −
CALL yourStoredProcedureName();
登录后复造
The above stored procedure can be called using CALL co妹妹and as shown in the below query −
mysql> call Sp_callTableStoredProcTable();
登录后复造
下列是输入 −
+-----------+------+ | FirstName | Age | +-----------+------+ | John | 两3 | | Bob | 两4 | | David | 两0 | +-----------+------+ 3 rows in set (0.03 sec) Query OK, 0 rows affected (0.06 sec)
登录后复造
正在下面，咱们利用了表格 'StoredProcTable'，那个表格有三笔记录。应用存储历程默示了一切记载。
你可使用存储进程查抄表格外有几多笔记录 -
mysql> delimiter // mysql> create procedure CountingRecords() −> begin −> select count(*) as AllRecords from StoredProcTable; −> end // Query OK, 0 rows affected (0.19 sec) mysql> delimiter ;
登录后复造
Call the stored procedure using CALL co妹妹and. The query is as follows −
mysql> call CountingRecords();
登录后复造
下列输入表现纪录的计数 −
+------------+ | AllRecords | +------------+ | 3 | +------------+ 1 row in set (0.31 sec) Query OK, 0 rows affected (0.33 sec)
登录后复造
以上便是正在MySQL外建立带分隔符的存储历程的具体形式，更多请存眷萤水红IT仄台此外相闭文章！
