Question

Using MySQL, How do I import a user defined database function from one db server to another db server using phpmyadmin?

A list of user defined functions can be fetched using this SQL:

select * from information_schema.routines;

Here is My function I want to move to a different database server:

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

But I get an error:

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 

Answer 1

Hope this is possible in phpmyadmin:

• Execute SHOW CREATE FUNCTION
• You will see CREATE FUNCTION statement, execute it against another MySQL server
• Repeat this steps for each function.

Note, that functions may have security options (DEFINER, SQL SECURITY), read about these options in the documentation (CREATE PROCEDURE and CREATE FUNCTION Syntax); if you want to use them, check that specified users are created on another server.

SHOW CREATE FUNCTION Syntax.
