Question

我正在尝试创建存储过程，但它失败了，我不知道为什么？请求：

delimiter //
drop  procedure if exists sp_edit_booking_owner;
create procedure sp_edit_booking_owner(v_pnr varchar(32), v_login varchar(200))

begin 
declare l_iduser int(11) default null; 

SELECT id_user INTO l_iduser FROM users WHERE userlogin = v_login;

if l_iduser is not null then                  

update book set iduser_c = l_iduser where bookingref = v_pnr;
update seg s join book b on s.id_book = b.id_book set s.id_user = l_iduser where b.bookingref = v_pnr;
update segmentown so join seg s on s.id_seg = so.id_seg join book b on s.id_book = b.id_book set so.id_user = l_iduser where b.bookingref = v_pnr;
update historyb hb join seg s on s.id_seg = hb.id_seg join book b on s.id_book = b.idbooking join users u on u.iduser = s.id_user_m set hb.eventowner = u.username where b.bookingref = v_pnr and  hb.event not like '%USER%';
update historyb hb join seg s on s.id_seg = hb.id_seg join book b on s.id_book = b.idbook join users u on u.id_user = s.id_user_m set hb.event = concat(u.username, '(USER)') where b.bookingpnr = v_pnr and  hb.event like '%USER%';

end if;

end;
//
delimiter ;

这可能是一个合成器问题，但我不知道从哪里来...... 有人有想法吗？

感谢。

Answer 1

如果更改分隔符，则需要使用它，直到再次更改

delimiter //
drop  procedure if exists sp_edit_booking_owner //
create procedure sp_edit_booking_owner(v_pnr varchar(32), v_login varchar(200))
...

修复此问题，我可以在MySQL上使用

使用此代码：

它的作品;）


delimiter //
drop  procedure if exists sp_edit_booking_owner//
create procedure sp_edit_booking_owner(IN v_pnr varchar(32),IN v_login varchar(200))

begin 
declare l_iduser int(11) default null; 

SELECT id_user INTO l_iduser FROM users WHERE userlogin = v_login;

if l_iduser is not null then                  

update book set iduser_c = l_iduser where bookingref = v_pnr;
update seg s join book b on s.id_book = b.id_book set s.id_user = l_iduser where b.bookingref = v_pnr;
update segmentown so join seg s on s.id_seg = so.id_seg join book b on s.id_book = b.id_book set so.id_user = l_iduser where b.bookingref = v_pnr;
update historyb hb join seg s on s.id_seg = hb.id_seg join book b on s.id_book = b.idbooking join users u on u.iduser = s.id_user_m set hb.eventowner = u.username where b.bookingref = v_pnr and  hb.event not like '%USER%';
update historyb hb join seg s on s.id_seg = hb.id_seg join book b on s.id_book = b.idbook join users u on u.id_user = s.id_user_m set hb.event = concat(u.username, '(USER)') where b.bookingpnr = v_pnr and  hb.event like '%USER%';

end if;

end//

delimiter ;

感谢您的回复。事实上，我的第一次请求并没有错。

您只需通过终端（命令行中的mysql）执行此请求。

再次感谢。
