I am trying to create a function in MySQL:
Here is the SQL code:
CREATE FUNCTION F_Dist3D (x1 decimal, y1 decimal)
RETURNS decimal
DETERMINISTIC
BEGIN
DECLARE dist decimal;
SET dist = SQRT(x1 - y1);
RETURN dist;
END;
I am getting the following error:
#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 10
I am running this create statement in phpMyAdmin. What is wrong with this function?
You have to override your ; delimiter with something like $$ to avoid this kind of error.
After your function definition, you can set the delimiter back to ;.
This should work:
DELIMITER $$
CREATE FUNCTION F_Dist3D (x1 decimal, y1 decimal)
RETURNS decimal
DETERMINISTIC
BEGIN
DECLARE dist decimal;
SET dist = SQRT(x1 - y1);
RETURN dist;
END$$
DELIMITER ;
MySQL create function syntax:
DELIMITER //
CREATE FUNCTION GETFULLNAME(fname CHAR(250),lname CHAR(250))
RETURNS CHAR(250)
BEGIN
DECLARE fullname CHAR(250);
SET fullname=CONCAT(fname,' ',lname);
RETURN fullname;
END //
DELIMITER ;
Use This Function In Your Query
SELECT a.*,GETFULLNAME(a.fname,a.lname) FROM namedbtbl as a
SELECT GETFULLNAME("Biswarup","Adhikari") as myname;
