I have the fallowing procedure:
DELIMITER $$
CREATE OR REPLACE PROCEDURE add_comments
AS
BEGIN
DECLARE var INT;
SELECT grade INTO var FROM table1;
IF (var <= 7) THEN
UPDATE table2 set comment = not_good;
ELSE
UPDATE table2 set comment = good;
END IF;
END$$
comment, not_good and good are all columns from table2
but it gives me the error:
#1064 - 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 'AS
BEGIN
IF (var <= 7)
BEGIN
UPDATE table2 set comment ' at line 3
Can't find out the problem, can someone help me with this?
Thanks!
Replace
DELIMITER $$
CREATE OR REPLACE PROCEDURE add_comments
AS
BEGIN
With
DELIMITER $$
CREATE OR REPLACE PROCEDURE add_comments()
BEGIN
PS: add brackets and remove "AS"
Remove that AS operator from your procedure code body. Your procedure should look like
DELIMITER $$
CREATE OR REPLACE PROCEDURE add_comments
BEGIN
DECLARE var INT;
SELECT grade INTO var FROM table1;
IF (var <= 7) THEN
UPDATE table2 set comment = not_good;
ELSE
UPDATE table2 set comment = good;
END IF;
END$$

this is my trigger
CREATE TRIGGER `proximo_pago` BEFORE INSERT ON `pago`
FOR EACH ROW BEGIN
declare num_orden integer;
select max(orden) from pago where lote=NEW.lote into num_orden;
if(num_orden is NULL)
then
set NEW.orden=1;
else
set NEW.orden=num_orden+1;
end if;
END
and the ERROR
SQL query:
CREATE TRIGGER `proximo_pago` BEFORE INSERT ON `pago`
FOR EACH ROW BEGIN
declare num_orden integer;
MySQL said: Documentation

I've tried to use DELIMITER but it isn´t works, please help me , thanks
My answer is based only on the necessity of your question which is declaration of the variable.. if the Delimiter doesn't do the trick maybe its an error in your syntax because you didn't SET your SELECT query in a variable. try this first.
DELIMITER $$
CREATE
TRIGGER `proximo_pago` BEFORE INSERT
on `pago`
FOR EACH ROW
BEGIN
DECLARE num_orden int;
SET num_orden = select max(orden) from pago where lote=NEW.lote;
if(num_orden is NULL)
then
set NEW.orden=1;
else
set NEW.orden=num_orden+1;
end if;
END$$
DELIMITER ;
I am writing PLSQL trigger for MySQL database. I am trying to declare variables . So i am writing a declare block in the trigger. Here is my following code
CREATE TRIGGER leave_approve_trigger
AFTER UPDATE ON leave_status
FOR EACH ROW
DECLARE //Syntax error
current_id integer;
BEGIN
if NEW.status == 'APPROVED'
THEN
select id into current_id from leave_request_table;
insert into update_table values(current_id);
ENDIF;
END;
The error I get is syntax error for mysql version 5.5.0. Can we actually declare variables. Thanks in advance
The procedure syntax in a little different in MySQL, you must change some lines:
Declare block must be after begin of code.
the == operator but chanted to =
ENDIF; must change to END IF;
All block must begin with changing the delimiter for statements, and at the end restore it.
If a field name is a reserved word it can be enclosed by ` to avoid syntax error.
Here is the code:
DELIMITER $$
CREATE TRIGGER leave_approve_trigger
AFTER UPDATE ON leave_status
FOR EACH ROW
BEGIN
DECLARE current_id int;
if NEW.`status` = 'APPROVED' THEN
select id into current_id from leave_request_table;
insert into update_table values(current_id);
END IF;
END$$
DELIMITER ;
I think the MySQL version would be more like this:
delimiter $$
CREATE TRIGGER leave_approve_trigger AFTER UPDATE ON leave_status
FOR EACH ROW
BEGIN
if NEW.status = 'APPROVED' THEN
insert into update_table
select id
from leave_request_table;
END IF;
END;
delimiter ;
By the way, you don't need the variable in either Oracle or MySQL. Just use insert . . . select.
I would think that you would also want to match to a specific row in the leave_request_table, but your trigger doesn't do that.
I am trying to create a trigger that marks items as deleted when they are inserted into the database.
Sadly I can't get my DECLARE to stop erroring, I have looked at the DECLARE docs and also at a few examples but I must be missing something.
The query I have so far is:
CREATE TRIGGER set_deleted BEFORE INSERT ON customercontact
FOR EACH ROW
BEGIN
DECLARE numrow INT; /* line 4 */
SELECT COUNT(*)
INTO numrow
FROM orders
WHERE NEW.order_id = 1;
if numrow >= 1 THEN
SET new.deleted = 1;
END IF;
END
The error message is showing:
#1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '' at line 4
Thanks for your help and preventing me from defenestrating myself!
Try this:
DELIMITER $$
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$$
DELIMITER ;
You need to change the delimiter when you create TRIGGER or STORED PROCEDURE.
By default, MySQL itself recognizes the semicolon as a statement delimiter, so you must redefine the delimiter temporarily to cause MySQL to pass the entire stored program definition to the server. Otherwise, MySQL breaks CREATE TRIGGER, before it reaches the END statement (on the first semicolon, which, in your case, is DECLARE statement).
You can see the documentation for more details:
http://dev.mysql.com/doc/refman/5.5/en/stored-programs-defining.html
I am trying to write trigger in Mysql (5.1), but getting following error, please help.
The error is:
SQL Error (1064): You have an error in your SQL syntax; check the
manual that corresponds to your MySQL server version for the right
syntax to use near '' at line 5.
Purpose for writing trigger:
I am writing application where I am assigning users, and I want to store unassigned usercount to field cluster_count in IX_branchdetails table.After updating the base table.
trigger:
DELIMITER $$
CREATE TRIGGER upd_trg AFTER
UPDATE ON DBNAME.BASETABLE
FOR EACH ROW
BEGIN
DECLARE m_branchcode INTEGER;
DECLARE cnt INTEGER;
DECLARE cursor_branch CURSOR FOR
SELECT DISTINCT branchcode
FROM ix_branchdetails;
DECLARE CONTINUE HANDLER FOR NOT FOUND SET done = TRUE;
open cursor_branch;
my_loop: loop
set done = false;
fetch cursor_branch into m_branchcode;
if done then
leave my_loop;
end if;
select count(1) into cnt from (select count(1) from BASETABLE Where IX_BRANCHCODE = m_branchcode) as temp;
update DBANAME.ix_branchdetails set DBANAME.ix_branchdetails.cluster_count = cnt where DBANAME.ix_branchdetails.BRANCHCODE = m_branchcode;
end loop my_loop;
close cursor_branch;
END $$
DELIMITER ;
I don't see a declare for the done variable:
DECLARE done TINYINT DEFAULT FALSE;
The semicolon (;) is the default delimiter for MySQL statements. To get a procedure/function/trigger defined, we normally see the statement delimiter changed to a string that doesn't appear in the statement:
DELIMITER $$
CREATE PROCEDURE ...
END$$
DELIMITER ;
If the delimiter is not changed from the semicolon, then when MySQL encounters the first semicolon in your procedure/function/trigger, it sees that as the end of the statement, which is not what you want. You want MySQL to see the entire block of code as a single statement.
I am trying to create a simple Stored procedure that allows me to conduct mass inserts, However I am running into syntactical troubles and unable to figure out where what's going wrong, despite comparing my procedure syntax to existing examples, and it seems to be correct.
CREATE PROCEDURE populateUserTable()
BEGIN
DECLARE counter int(10);
SET counter = 1;
WHILE counter < 101 DO
INSERT INTO user(userid) values(counter);
SET counter = counter + 1
END WHILE;
END
Upon running, MYSQL states:
You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '' at line 3
and highlits this guy:
CREATE PROCEDURE populateUserTable( ) BEGIN DECLARE counter INT( 10 ) ;
What's up here?
Have you used
DELIMITER $$
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 ;
