MySQL,phpmyadmin,如何导入用户定义的函数

Question

使用MySQL,如何使用phpmyadmin将用户定义的数据库功能从一个数据库服务器导入另一个数据库服务器？

可以使用此SQL获取用户定义函数的列表:

select * from information_schema.routines;

这是我想要移动到不同数据库服务器的我的函数:

CREATE DEFINER=`XXX`@`%` FUNCTION `BDayDiff`( d1 DATE, d2 DATE ) RETURNS int(11)
   DETERMINISTIC
BEGIN
 DECLARE dow1, dow2, days, wknddays INT;
 SET dow1 = DAYOFWEEK(d1);
 SET dow2 = DAYOFWEEK(d2);
 SET days = DATEDIFF(d2,d1);
 SET wknddays = 2 * FLOOR( days / 7 ) +
                IF( dow1 = 1 AND dow2 > 1, 1,                              
                    IF( dow1 = 7 AND dow2 = 1, 1,              
                        IF( dow1 > 1 AND dow1 > dow2, 2,      
                            IF( dow1 < 7 AND dow2 = 7, 1, 0 )  
                          )
                      )
                  );
 RETURN FLOOR(days - wkndDays);
END

但是我收到一个错误:

Error

SQL query:

CREATE DEFINER = `XXX`@`%` FUNCTION `BDayDiff` (
d1 DATE,
d2 DATE
) RETURNS INT( 11 ) DETERMINISTIC BEGIN DECLARE dow1,
dow2,
days,
wknddays INT;

MySQL said: Documentation
#1064 - You have an error in your SQL syntax; check the manual that 
corresponds to your MySQL server version for the right syntax to use 
near '' at line 5

通过添加$来尝试这个,它对我有用.

DELIMITER $

CREATE DEFINER=`XXX`@`%` FUNCTION `BDayDiff`( d1 DATE, d2 DATE ) RETURNS int(11)
   DETERMINISTIC
BEGIN
 DECLARE dow1, dow2, days, wknddays INT;
 SET dow1 = DAYOFWEEK(d1);
 SET dow2 = DAYOFWEEK(d2);
 SET days = DATEDIFF(d2,d1);
 SET wknddays = 2 * FLOOR( days / 7 ) +
                IF( dow1 = 1 AND dow2 > 1, 1,                              
                    IF( dow1 = 7 AND dow2 = 1, 1,              
                        IF( dow1 > 1 AND dow1 > dow2, 2,      
                            IF( dow1 < 7 AND dow2 = 7, 1, 0 )  
                          )
                      )
                  );
 RETURN FLOOR(days - wkndDays);
END$
