How do I combine CREATE PROCEDURE scripts in MySQL
In MySQL I want to write a script and put multiple CREATE PROCEDURE
statements into it, the usual ;
won't work for some reason. Is there another way to run multiple CREATE
statements in the same script? If so, ho开发者_如何转开发w?
not much to it really (foo.sql)
you can run this from the mysql command line using \. foo.sql
use foo_db;
-- TABLES
drop table if exists users;
create table users
(
user_id int unsigned not null auto_increment primary key,
username varbinary(32) unique not null,
created_date datetime not null
)
engine=innodb;
-- PROCEDURES
drop procedure if exists list_users;
delimiter #
create procedure list_users()
proc_main:begin
select * from users order by username;
end proc_main #
delimiter ;
drop procedure if exists get_user;
delimiter #
create procedure get_user
(
p_user_id int unsigned
)
proc_main:begin
select * from users where user_id = p_user_id;
end proc_main #
delimiter ;
-- TEST DATA
insert into users (username, created_date) values
('f00',now()),('bar',now()),('alpha',now()),('beta',now());
-- TESTING
call list_users();
call get_user(1);
Before the first procedure/function declaration define a delimiter thus:
DELIMITER |
After the first procedure/function declaration close the delimiter: |
Do the same for each procedure/function and the entire script will run as one.
So you end up with this:
DELIMITER |
script 1 text
|
DELIMITER |
script 2 text
|
DELIMITER |
script 3 text
|
According to the MySQL FAQ:
24.4.8: Is it possible to group stored procedures or stored functions into packages?
No. This is not supported in MySQL 5.1.
If you're not really trying to form a package, you can try (temporarily) redefining the delimiter:
delimiter //
