I"m continiously receiving this error when trying to create this stored procedure. I'm trying to write a procedure that splits a comma delimited string. Similar to explode. I feel I'm close.
This is the 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 'DECLARE start_pos, end_pos INT;
SET start_pos = 1;
SET end_pos = Locat' at line 6
I copied the logic from a SQL Server example and did my best translate it to MySql syntax.
This is the entire procedure from start to finish. I'm hoping a well trained eye can explain why I'm getting an error.
DELIMITER $$
CREATE procedure split_string (in p_string_to_split VARCHAR(255),in p_delimiter CHAR(1) )
BEGIN
DROP TEMPORARY TABLE IF EXISTS split_channel_ids;
CREATE TEMPORARY TABLE split_channel_ids (p_channel_id int);
DECLARE start_pos, end_pos INT;
SET start_pos = 1;
SET end_pos = Locate(p_delimiter, p_string_to_split);
WHILE (start_pos < CHAR_LENGTH(p_string_to_split) + 1) DO
IF (end_pos = 0) THEN
SET end_pos = CHAR_LENGTH(p_string_to_split) + 1;
END IF;

END WHILE;

DECLARE statements (in MySQL) must be at the beginning of their enclosing BEGIN...END block.
In MS SQL, they can be anywhere; but it is annoying there because they do not have block scope, they have procedure scope, so you can't "re-use" names in independent blocks.

I tried to make a simple procedure in MariaDB 10.2 but I encountered an issue regarding variables defining.
I am receiving (conn:107) You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near '' at line 3 message when I declare a variable.
I read the MariaDB documentation and I it says that a variable is defined like this DECLARE var_name [, var_name] ... type [DEFAULT value]
Where I am wrong? I am coming from Oracle SQL and some sintax is wired for me.
I use Eclipse with MariaDB JDBC to connect on SQL.
CREATE PROCEDURE nom_jobs_insert(IN p_name varchar(100) CHARACTER SET 'utf8')
BEGIN
DECLARE counter INT DEFAULT 0;
SELECT count(*) INTO counter
FROM nom_jobs
WHERE lower(name) = lower(p_name)
IF counter = 1 THEN
INSERT INTO nom_jobs(name) VALUES (p_name);
END IF;
END;
I found the solution.
In MariaDB you have to define a delimiter before create a procedure and you need to mark where the procedure code is finished.
DELIMITER //
CREATE PROCEDURE nom_jobs_insert(IN p_name varchar(100) CHARACTER SET 'utf8')
BEGIN
DECLARE counter INT DEFAULT 0;
SELECT count(*) INTO counter
FROM nom_jobs
WHERE lower(name) = lower(p_name);
IF counter = 1 THEN
INSERT INTO nom_jobs(name) VALUES (p_name);
END IF;
END; //
You have error not in DECLARE expression, add ; after SELECT statement
Here are the clues that point to a missing DELIMITER:
near '' at line 3
Line 3 contains the first ;
When the error says near '', the parser thinks it has run off the end of the "statement".
Put those together -- it thinks that there is one 3-line statement ending with ;. But the CREATE PROCEDURE should be longer than that.
CREATE PROCEDURE nom_jobs_insert(IN p_name varchar(100) CHARACTER SET 'utf8')
IS
DECLARE counter INTEGER DEFAULT 0;
BEGIN
SELECT count(*) INTO counter
FROM nom_jobs
WHERE lower(name) = lower(p_name)
IF counter = 1 THEN
INSERT INTO nom_jobs(name) VALUES (p_name);
END IF;
END;
I have a stored procedure in Mysql database like this:

This documentation refers to having the DECLARE statements at the top and also before the creation of any CURSORS and HANDLERS, which you are following but not at the beginning of the BEGIN... END block.
This documentation clarifies the question that OP had posted!
It is mandatory to have your declarations at the begin of your BEGIN... END block, but not under an UPDATE statement.
Additional reference to a similar issue can be found on this question, even which refers to the same solution.
Hope this helps!
I am trying to create a trigger that marks items as deleted when they are inserted into the database.
Sadly I can't get my DECLARE to stop erroring, I have looked at the DECLARE docs and also at a few examples but I must be missing something.
The query I have so far is:
CREATE TRIGGER set_deleted BEFORE INSERT ON customercontact
FOR EACH ROW
BEGIN
DECLARE numrow INT; /* line 4 */
SELECT COUNT(*)
INTO numrow
FROM orders
WHERE NEW.order_id = 1;
if numrow >= 1 THEN
SET new.deleted = 1;
END IF;
END
The error message is showing:
#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 4
Thanks for your help and preventing me from defenestrating myself!
Try this:
DELIMITER $$
CREATE TRIGGER set_deleted BEFORE INSERT ON customercontact
FOR EACH ROW
BEGIN
DECLARE numrow INT; /* line 4 */
SELECT COUNT(*)
INTO numrow
FROM orders
WHERE NEW.order_id = 1;
if numrow >= 1 THEN
SET new.deleted = 1;
END IF;
END$$
DELIMITER ;
You need to change the delimiter when you create TRIGGER or STORED PROCEDURE.
By default, MySQL itself recognizes the semicolon as a statement delimiter, so you must redefine the delimiter temporarily to cause MySQL to pass the entire stored program definition to the server. Otherwise, MySQL breaks CREATE TRIGGER, before it reaches the END statement (on the first semicolon, which, in your case, is DECLARE statement).
You can see the documentation for more details:
http://dev.mysql.com/doc/refman/5.5/en/stored-programs-defining.html
I found this function for capitalizing the first letter of words in a string, but it is giving me a syntax error on line 8 when I try to run it in SQL in PHPMyadmin. Can anyone help me sort out what the problem is?
Here is the code:
CREATE FUNCTION CAP_FIRST (input VARCHAR(255))
RETURNS VARCHAR(255)
DETERMINISTIC
BEGIN
DECLARE len INT;
DECLARE i INT;
SET len = CHAR_LENGTH(input);
SET input = LOWER(input);
SET i = 0;
WHILE (i < len) DO
IF (MID(input,i,1) = ' ' OR i = 0) THEN
IF (i < len) THEN
SET input = CONCAT(
LEFT(input,i),
UPPER(MID(input,i + 1,1)),
RIGHT(input,len - i - 1)
);
END IF;
END IF;
SET i = i + 1;
END WHILE;
RETURN input;
END;
And this is the error:
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 8
The delimiter signals the DB engine the end of your statement. Normally it is ;. But that would end the stored procedure at the first ;. And its definition would be incomplete.
You can change the delimiter and add it to the end of your procedure. After that change the delimiter back to ;
delimiter |
CREATE FUNCTION CAP_FIRST (input VARCHAR(255))
...
END;
|
delimiter ;
I am trying to create a simple Stored procedure that allows me to conduct mass inserts, However I am running into syntactical troubles and unable to figure out where what's going wrong, despite comparing my procedure syntax to existing examples, and it seems to be correct.
CREATE PROCEDURE populateUserTable()
BEGIN
DECLARE counter int(10);
SET counter = 1;
WHILE counter < 101 DO
INSERT INTO user(userid) values(counter);
SET counter = counter + 1
END WHILE;
END
Upon running, MYSQL states:
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
and highlits this guy:
CREATE PROCEDURE populateUserTable( ) BEGIN DECLARE counter INT( 10 ) ;
What's up here?
Have you used
DELIMITER $$
At the start?
Try
DELIMITER $$
CREATE PROCEDURE populateUserTable()
BEGIN
DECLARE counter int(10);
SET counter = 1;
WHILE counter < 101 DO
INSERT INTO user(userid) values(counter);
SET counter = counter + 1
END WHILE;
END $$
DELIMITER ;
