I am getting a syntax error with this simple sample script in MySql 5.6.17 :
CREATE FUNCTION sampldb.fn_x(param VARCHAR(20))
RETURNS int
BEGIN
return 1;
END
What am i doing wrong? In Sql workbench, the error is shown in the last 2 lines.
use DELIMITER
DELIMITER //
CREATE FUNCTION sampldb.fn_x(param VARCHAR(20))
RETURNS int
BEGIN
return 1;
END

i have a problem with the next code:
create function proc1 (id int)
returns float
begin
declare sum float
select sum = (note1+note2+note3)/3 from test1.note where note.id=id;
return sum;
end
I got this 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 'select sum = (note.note1+note.note2+note.note3)/3 from test1.note where note.id=' at line 5
I've spent much time searching for a solution but no solution was found :(
delimiter |
create function proc1 (id int)
returns float
begin
declare sum float;
select (note1+note2+note3)/3 into sum from test1.note where note.id=id;
return sum;
end
|
delimiter ;
You had multiple errors:
no delimiter defined. Otherwise the DB thinks your function definition stops at the first ; which is wrong
you need to use select ... into. Otherwise you get a "not allowed to return a resultset from a function" error
you forgot a semicolon after your declare
Use set instead of select or better return without declaring a variable:
delimiter //
create function proc1 (id int)
returns float
begin
return (select (note1+note2+note3)/3 from test1.note where note.id=id);
end
//
delimiter ;
or with variable:
delimiter //
create function proc1 (id int)
returns float
begin
declare sum float;
set sum = (select (note1+note2+note3)/3 from test1.note where note.id=id);
return sum;
end
//
delimiter ;
I'm getting the following error whenever i'm trying to create the following function in mysql.
error : 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 4
And my function is
CREATE FUNCTION GET_HOUR_MINUTES(seconds INT)
RETURNS VARCHAR(16)
BEGIN
DECLARE result VARCHAR(16);
IF seconds >= 3600 THEN SET result = TIME_FORMAT(SEC_TO_TIME(seconds),'%kh %lm');
ELSE SET result = TIME_FORMAT(SEC_TO_TIME(seconds),'%lm');
RETURN result;
END
You need to change the delimiter before creating a function. If you don't your CREATE statement terminates at the first semi-colon.
Try this:
DELIMITER $$
CREATE FUNCTION GET_HOUR_MINUTES(seconds INT)
RETURNS VARCHAR(16)
BEGIN
DECLARE result VARCHAR(16);
IF seconds >= 3600 THEN SET result = TIME_FORMAT(SEC_TO_TIME(seconds),'%kh %lm');
ELSE SET result = TIME_FORMAT(SEC_TO_TIME(seconds),'%lm');
END IF
RETURN result;
END$$
DELIMITER ;
Thanks to #Ravinder for catching the missing END IF.
Here is my code:
create function getten() returns integer
begin
return 10;
end
giving me error message:
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 3
I have no idea what the '' is all about. Any help please?
First of all, SQL code is written in big letters.
Second, please remember indention.
DELIMITER $$
CREATE FUNCTION getten()
RETURNS INTEGER
LANGUAGE SQL
BEGIN
RETURN 10;
END;
$$
DELIMITER ;
should work like this.
This works for me...
DELIMITER $$
CREATE FUNCTION getten()
RETURNS INTEGER
BEGIN
RETURN 10;
END;
$$
DELIMITER ;
SELECT getten();
+----------+
| getten() |
+----------+
| 10 |
+----------+
Try this you need to define the type of return in function
DELIMITER $$
CREATE
FUNCTION `getten`()
RETURNS INTEGER
BEGIN
RETURN 10;
END$$
DELIMITER ;
And after creation you can use it like
SELECT `getten`()
When you have only one statement to be executed, you need not use begin - end.
create function getten() returns integer return 10;
Otherwise you need default syntax to bind multiple statements within begin - end block.
And to restrict the database engine interpret the statements immediately when it finds a default statement close instruction by a semi colon, we use custom delimiter.
delimiter //
create function getten() returns integer
begin
return 10;
end;
//
delimiter ;
It would be a good practice to follow using the block type body rather than using an inline single statement.
All your answers were great, but only worked after I added 'deterministic' before 'begin'.
Thanks a lot.
I try to write mysql function. I have mysql 5.6, and I don`t know why every time i try do it:
CREATE FUNCTION do_it (s INT) RETURNS INT
BEGIN
DECLARE k INT;
SET k= s + 2;
RETURN k;
END;
I get:
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 1 */
I know it is basic mistake, but I don`t know how I can fix it...
You need to change the delimiter that MySQL is using or it will stop processing the CREATE request after the first semi-colon.
Do this:
DELIMITER $$
CREATE FUNCTION do_it (s INT) RETURNS INT
BEGIN
DECLARE k INT;
SET k= s + 2;
RETURN k;
END$$
DELIMITER ;
I have a problem. I created a function in MySQL which returns a String (varchar data type).
Here's the syntax:
DELIMITER $$
USE `inv_sbmanis`$$
DROP FUNCTION IF EXISTS `SafetyStockChecker`$$
CREATE DEFINER=`root`#`localhost` FUNCTION `SafetyStockChecker`
(jumlah INT, safetystock INT)
RETURNS VARCHAR(10) CHARSET latin1
BEGIN
DECLARE statbarang VARCHAR(10);
IF jumlah > safetystock THEN SET statbarang = "Stabil";
ELSEIF jumlah = safetystock THEN SET statbarang = "Perhatian";
ELSE SET statbarang = "Kritis";
END IF;
RETURN (statbarang);
END$$
DELIMITER ;
When I call the function like call SafetyStockChecker(16,16), I get this error:
Query : call SafetyStockChecker(16,16)
Error Code : 1305
PROCEDURE inv_sbmanis.SafetyStockChecker does not exist
Execution Time : 00:00:00:000
Transfer Time : 00:00:00:000
Total Time : 00:00:00:000
What's wrong with the function?
That is not the correct way to call a function. Here's an example to call a function:
SELECT SafetyStockChecker(16,16) FROM TableName
The way you are doing now is for calling a STORED PROCEDURE. That is why the error says:
PROCEDURE inv_sbmanis.SafetyStockChecker does not exist
because it is searching for a Stored procedure and not a function.
You should use
SELECT SafetyStockChecker(16,16)
