mysql trigger insert in multiple table by condition - mysql
I want to split rows using trigger, to 2 different tables if rows are more then 5 then insert only 5 rows to table leave and others rows to table nonpay_leave . I have a working trigger which insert rows only in one (I included trigger and my database code at the bottom of question).
currently working trigger
I have a table called staff_leave_application which have this columns :
id_staff_leave_application | staff_id_staff | leave_type_id_leave_type | start_date | end_date | joining_date
and it has a trigger called tn_air_staff_leave_application:
DELIMITER $$
USE `mydb`$$
CREATE
DEFINER=`root`#`localhost`
TRIGGER `mydb`.`tn_air_staff_leave_application`
AFTER INSERT ON `mydb`.`staff_leave_application`
FOR EACH ROW
BEGIN
SET #counter := -1;
WHILE (#counter < DATEDIFF(DATE(new.end_date), DATE(new.start_date))) DO
INSERT INTO `leave`(staff_leave_application_id_staff_leave_application, staff_leave_application_staff_id_staff, leave_type_id_leave_type, date, active, date_updated)
VALUES (new.id_staff_leave_application, new.staff_id_staff, new.leave_type_id_leave_type, DATE_ADD(new.start_date, INTERVAL #counter:=#counter + 1 DAY), 1, CURDATE());
END WHILE;
END$$
what above trigger actually do?
This trigger run after insert on staff_leave_application. The trigger split currently inserted row in staff_leave_application by per day per row from date range and then insert rows to the table called leave each day per row.
Then, What i want actually ???
I want to change this trigger, so that if new rows are more then 5 then insert other rows to another table called nonpay_leave. like:
if trigger generates 7 rows, then insert first 5 rows to table leave and other 2 rows to table nonpay_leave.

* ur original counter adjusted to either +4 in the 2nd loop (not sure which one, sorta confused but i think it shud be +4 or it cud be
-6)
Ok i have edited and think this is what the new logic shud b.. many counters have changed
well alrite i get u, now u will have to do what u said.. before u enter any loop.. loop1 (max times it can execute is #balance times).. loop2 (it shud compulsarily execute the remainder times).. i think u shud set a new counter called leave_counter in the beginning itself which will determine how many times the Leave Loop will execute..

BOTTOMLINE::::::
i have edited ur sql command by introducing a new counter called leave_counter which will determine how many times ur leave_loop shud run.. also in the first loop i have made sure that it does not execute more than #balance times by introducing the #balance in the first loop.. u can see the edited reply.. Loop 1: Executes max (#balance) times... Loop 2: Executes (no of days leave taken) - (#balance) times ...

MySQL getting always error 1451 on update a single value in a table
I need a very little help.... I have two tables A and B where B contains a field that is in constraint key with the ID field of table A. Since I needed to update for a record of A the ID taken from another database, equal to the one I am working on, but with the ID in question "correct", so I did: dropped the foreign key of table B on that field referenced to the ID of A updated at all records on the old value of the field in B with the new value of reference ID where that field of B = to the old value then I update the ID of table A with the new value and I get back error 1451 of foreign key on that field of B that I had already updated without problems even if I had dropped the foreign key in B already; then I do SET FOREIGN_KEY_CHECKS = 0; I try to update the ID of table A for that record with the new value but I always get error 1451 ..... since I dropped the foreign key and did the set as well, is there something else or command that I have to consider? thanks everyone in advance to all! EDIT: precisely I followed like this scenario: CREATE TABLE sample_A ( ID bigint(20) UNSIGNED NOT NULL, product varchar(60) COLLATE utf8mb4_unicode_ci NOT NULL DEFAULT '', ) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_unicode_ci; CREATE TABLE sample_B ( ID bigint(20) UNSIGNED NOT NULL, ref_id_sample_A_id bigint(20) UNSIGNED NOT NULL, document_name varchar(300) COLLATE utf8mb4_unicode_ci DEFAULT NULL ) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_unicode_ci; ALTER TABLE sample_A ADD PRIMARY KEY ( ID ) ALTER TABLE sample_A MODIFY ID bigint(20) UNSIGNED NOT NULL AUTO_INCREMENT, AUTO_INCREMENT=211388375; COMMIT; ALTER TABLE sample_B ADD PRIMARY KEY ( ID ); ALTER TABLE sample_B MODIFY ID bigint(20) UNSIGNED NOT NULL AUTO_INCREMENT, AUTO_INCREMENT=158; ALTER TABLE sample_B ADD CONSTRAINT fk_sample_A_sample_B_ref_id FOREIGN KEY ( ref_id_sample_A_id ) REFERENCES sample_A ( ID ); COMMIT; INSERT INTO sample_A (ID, product) VALUES (1, 'product 1'), (211388370, 'product 2'), (211388371, 'product 3'), (211388372, 'product 4'), (211388373, 'product 5'); INSERT INTO sample_B (ID, ref_id_sample_A_id, document_name) VALUES (1, 211388372, 'document 1'), (2, 211388371, 'document 2'), (3, 1, 'document 3'), (4, 211388373, 'document 4'), (5, 1, 'document 5'), (6, 211388370, 'document 6'), (7, 211388371, 'document 7'); via phpMyAdmin , dropped foreign key fk_sample_A_sample_B_ref_id UPDATE sample_B SET ref_id_sample_A_id = 211388369 WHERE ref_id_sample_A_id = 1; <---- OK UPDATE sample_A SET ID = 211388369 WHERE ID = 1; <---- error 1451 SET FOREIGN_KEY_CHECKS = 0; UPDATE sample_A SET ID = 211388369 WHERE ID = 1; <---- error 1451 again next operation would be ALTER TABLE sample_B ADD CONSTRAINT fk_sample_A_sample_B_ref_id FOREIGN KEY ( ref_id_sample_A_id ) REFERENCES sample_A ( ID ); to restore foreign key
Nevermind... I solved... the problem was phpMyAdmin who had the option "check for foreigns enabled"... thanks anyway #Akina!

mysql trigger - update value, value= row count
I want to run a mysql trigger to update value of table leave_taken col num, when a table called leave was updated, inserted or deleted. Like if I insert this rows to leave: INSERT INTO `leave` (`id_leave`, `staff_leave_application_id_staff_leave_application`, `staff_leave_application_staff_id_staff`, `leave_type_id_leave_type`, `date`, `active`, `date_updated`) VALUES (7, 7, 6, 7, '2013-01-21', 1, '2013-01-18'), (8, 7, 6, 7, '2013-01-22', 1, '2013-01-18'), (9, 7, 6, 7, '2013-01-23', 1, '2013-01-18'), (10, 7, 6, 7, '2013-01-24', 1, '2013-01-18'), (11, 7, 6, 7, '2013-01-25', 2, '2013-01-18'); then table leave_taken col num value was updated to 5 where: staff_leave_application_staff_id_staff = currently updated staff_leave_application_staff_id_staff, and leave_type_id_leave_type = currently updated leave_type_id_leave_type I have included the Table below.

First, define a unique key over the identifying columns in your leave table: ALTER TABLE leave ADD UNIQUE (staff_leave_application_staff_id_staff, leave_type_id_leave_type); Then go ahead and define your triggers: CREATE TRIGGER my_insert_trigger AFTER INSERT ON leave FOR EACH ROW INSERT INTO leave_taken (staff_leave_application_staff_id_staff, leave_type_id_leave_type, num) VALUES (NEW.staff_leave_application_staff_id_staff, NEW.leave_type_id_leave_type, 1) ON DUPLICATE KEY UPDATE num = num + 1; CREATE TRIGGER my_delete_trigger AFTER DELETE ON leave FOR EACH ROW UPDATE leave_taken SET num = num - 1 WHERE staff_leave_application_staff_id_staff = OLD.staff_leave_application_staff_id_staff AND leave_type_id_leave_type = OLD.leave_type_id_leave_type; DELIMITER ;; CREATE TRIGGER my_update_trigger AFTER UPDATE ON leave FOR EACH ROW IF NOT ( NEW.staff_leave_application_staff_id_staff <=> OLD.staff_leave_application_staff_id_staff AND NEW.leave_type_id_leave_type <=> OLD.leave_type_id_leave_type ) THEN UPDATE leave_taken SET num = num - 1 WHERE staff_leave_application_staff_id_staff = OLD.staff_leave_application_staff_id_staff AND leave_type_id_leave_type = OLD.leave_type_id_leave_type; INSERT INTO leave_taken (staff_leave_application_staff_id_staff, leave_type_id_leave_type, num) VALUES (NEW.staff_leave_application_staff_id_staff, NEW.leave_type_id_leave_type, 1) ON DUPLICATE KEY UPDATE num = num + 1; END IF;; DELIMITER ;
if with mysql results in syntax error
I need to use a if statment in my mysql trigger. It looks like that: set #countentry = (SELECT count(id) as `id` FROM `tsc_page_have_wildcard` where idwildcard=1 and idpage=5); IF #countentry <> 0 THEN INSERT INTO `tsc_page_have_wildcard` (`idpage`, `idwildcard`) VALUES (#pageid, NEW.id); END IF By executing the trigger i get: Error Code: 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 'IF #countentry <> 0 THEN INSERT INTO `tsc_page_have_wildcard` (`i' at line 1 The table struct is the following: CREATE TABLE IF NOT EXISTS `tsc_page_have_wildcard` ( `id` int(11) NOT NULL auto_increment, `idpage` int(11) NOT NULL, `idwildcard` int(11) NOT NULL, PRIMARY KEY (`id`), KEY `idpage` (`idpage`,`idwildcard`), KEY `idwildcard` (`idwildcard`) ) ENGINE=InnoDB DEFAULT CHARSET=utf8 AUTO_INCREMENT=8 ; ALTER TABLE `tsc_page_have_wildcard` ADD CONSTRAINT `tsc_page_have_wildcard_ibfk_1` FOREIGN KEY (`idpage`) REFERENCES `tsc_page` (`id`) ON DELETE CASCADE ON UPDATE CASCADE, ADD CONSTRAINT `tsc_page_have_wildcard_ibfk_2` FOREIGN KEY (`idwildcard`) REFERENCES `tsc_wildcard` (`id`) ON DELETE CASCADE ON UPDATE CASCADE; INSERT INTO `tsc_page_have_wildcard` (`id`, `idpage`, `idwildcard`) VALUES (1, 1, 1), (2, 1, 2), (3, 1, 3), (4, 1, 4), (5, 1, 5), (6, 41, 4), (7, 41, 5); Does anyone know why this if statment isnt working in my trigger?
This code should work: DELIMITER $$ CREATE /*!50017 DEFINER = 'root'#'localhost' */ TRIGGER `win` AFTER INSERT ON `tsc_page_have_wildcard` FOR EACH ROW BEGIN SET #countentry = (SELECT COUNT(id) AS `id` FROM `tsc_page_have_wildcard` WHERE idwildcard = 1 AND idpage = 5) ; IF #countentry <> 0 THEN INSERT INTO `tsc_page_have_wildcard` (`idpage`, `idwildcard`) VALUES (#pageid, NEW.id) ; END IF ; END $$ DELIMITER ; Semi-colon(;) after END IF :-)
