Creating a trigger is not working as expected, whenever I try to insert data into master table it give me error that count does't match. I am unable to identify where I'm doing wrong.
I have attached error image please look for further demonstration
DELIMITER $$
DROP TRIGGER IF EXISTS `trg_apl_b_info_after_insert`
CREATE
TRIGGER `trg_apl_b_info_after_insert` AFTER INSERT ON `tbl_appli_basic_info`
FOR EACH ROW BEGIN
DECLARE vApplicant VARCHAR(256);
-- Find appli_basic_info_id & apli_reg_no of Applicant performing the INSERT into table
SELECT USER() INTO vApplicant;
-- Insert record into tbl_appli_basic_info_after_insert table
INSERT INTO tbl_appli_basic_info_after_insert
( appli_basic_info_id,
apli_reg_no,
full_name,
after_insert_datetime)
VALUES
( NEW.appli_basic_info_id,
NEW.apli_reg_no,
NEW.full_name,
SYSDATE(),
vApplicant );
END;
$$
DELIMITER ;
Error in phpMyAdmin
Your insert statement lists 4 fields however you provided 5 values. Hence count not matched.
I have this code for the trigger:
CREATE TRIGGER `insert_after` AFTER INSERT ON `hyk50_0001`
FOR EACH ROW BEGIN
INSERT INTO hyk50_0001_copy(Fecha)
SELECT Fecha FROM hyk50_0001
END;
but doesn't work, it says a syntax error but I didn't see it
I'm using Navicat. And hyk50_0001_copy it's a identical copy of hyk50_0001.
The target is take the new row of hyk50_0001 and INSERT in hyk50_0001_copy
I want put all the database, but if it doesn't work with only a value I can't progress.
I don't see a syntax error, but I assume you intend:
DELIMITER $$
CREATE TRIGGER `insert_after` AFTER INSERT ON `hyk50_0001`
FOR EACH ROW
BEGIN
INSERT INTO hyk50_0001_copy(Fecha)
VALUES (new.Fecha)
END;$$
DELIMITER ;
That is, you probably want to insert only the row that was just created.
I have two tables companies (id,company_name) and users (id,company_id,user_name);
Now I want to create a view when data is inserted in companies table.
I used following two ways but getting same error in both the cases. Error is :
#1422 - Explicit or implicit commit is not allowed in stored function or trigger.
First Query is :
DELIMITER $$
CREATE TRIGGER testInsert
AFTER INSERT ON companies
FOR EACH ROW BEGIN
CREATE VIEW test(user_name) AS
SELECT user_name
FROM users;
END$$
DELIMITER ;
Then I tried creating procedure first and called that procedure in trigger like this
create procedure createView()
create view vt as select * from users;
CREATE TRIGGER `testInsert3` AFTER INSERT ON `companies`
FOR EACH ROW
BEGIN
CALL createView();
END;
Please help me guys.
Thanks All.
please refer this link, i think this will help you
http://stackoverflow.com/questions/16256250/create-view-in-a-trigger
try creating the view like this
DELIMITER $$
CREATE TRIGGER testInsert
AFTER INSERT ON companies
FOR EACH ROW BEGIN
EXECUTE('CREATE VIEW test(user_name) AS SELECT user_name
FROM users')
END$$
DELIMITER ;
i am trying to create a trigger to concatenate my table columns into a single column but i can't find the error.
code:
create trigger molecule_trigger After insert on molecule
For each row
begin
Update molecule
Set molecule_text= CONCAT(mid,',',ULCHEm_ID,',',IUPAC_name,',',Inchi,',',inchi_key,',',smiles,',',can_smiles,',',Molecular_formula,',',Molecular_weight,',',vendor,',',CAS,',',links,',',image);
end;
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 6
You get this error, because you started a "multiple statements" block with begin, but the ; after your update statement terminates the create trigger statement before the end; statement.
You have to either change the delimiter
DELIMITER $$
create trigger molecule_trigger After insert on molecule
For each row
begin
Update molecule
Set molecule_text= CONCAT(mid,',',ULCHEm_ID,',',IUPAC_name,',',Inchi,',',inchi_key,',',smiles,',',can_smiles,',',Molecular_formula,',',Molecular_weight,',',vendor,',',CAS,',',links,',',image);
end $$
DELIMITER ;
Or you remove the begin and end.
create trigger molecule_trigger After insert on molecule
For each row
Update molecule
Set molecule_text= CONCAT(mid,',',ULCHEm_ID,',',IUPAC_name,',',Inchi,',',inchi_key,',',smiles,',',can_smiles,',',Molecular_formula,',',Molecular_weight,',',vendor,',',CAS,',',links,',',image);
Now, you have another problem. You're trying to do an action in the trigger on the same table as your trigger works on. This is not allowed. Change your trigger to this:
create trigger molecule_trigger BEFORE insert on molecule
For each row
SET NEW.molecule_text= CONCAT_WS(',', NEW.mid, NEW.ULCHEm_ID, NEW.IUPAC_name, NEW.Inchi, NEW.inchi_key, NEW.smiles, NEW.can_smiles, NEW.Molecular_formula, NEW.Molecular_weight, NEW.vendor, NEW.CAS, NEW.links, NEW.image);
Note though, that this sets the molecule_text only for the columns inserted. Your trigger updated the whole table each time a row is inserted. And if you insert 3 rows in one statement, your table gets updated 3 times. This is not what you want to do anyway :)
In MySQL I tried to define a trigger like this:
DELIMITER $$
CREATE TRIGGER vipInvite
AFTER INSERT ON meetings
FOR EACH ROW
BEGIN
IF(NOT EXISTS (SELECT * FROM participants
WHERE meetid = NEW.meetid AND pid ='vip'))
THEN
IF(EXISTS(SELECT * FROM meetings WHERE meetid = NEW.meetid AND slot > 16))
THEN
INSERT INTO participants(meetid, pid)
VALUES (NEW.meetid,(SELECT userid
FROM people WHERE people.group = 'tap' GROUP BY invite));
END IF;
END IF;
END $$
DELIMITER ;
Produces this error:
This version of MySQL doesn't yet support 'multiple triggers with the same action time and event for one table.
Is there a way to work around this so I can define multiple triggers?
This error means you already have an AFTER INSERT trigger on meetings table.
If it is the same trigger (meaning vipInvite) that you created earlier and now you want to replace it then you need to drop it first
DROP TRIGGER vipInvite;
DELIMITER $$
CREATE TRIGGER vipInvite
...
END$$
DELIMITER ;
Now if you have some other trigger you have to merge code from both triggers into one, then drop existing trigger, and then create a new one.
To show the list of existing triggers use SHOW TRIGGERS.
SHOW TRIGGERS WHERE `table` = 'meetings';
How to reproduce this error in MySQL:
ERROR 1235 (42000): This version of MySQL doesn't yet support 'multiple
triggers with the same action time and event for one table'
Run the following queries:
DELIMITER //
CREATE TRIGGER mytrigger1 AFTER INSERT ON mytable
FOR EACH ROW
BEGIN
END//
DELIMITER //
CREATE TRIGGER mytrigger2 AFTER INSERT ON mytable
FOR EACH ROW
BEGIN
END//
If you want to hook more than one action onto the same event/table, you will have to cram all of it into one trigger. You could call many stored procedures like this:
DELIMITER //
CREATE TRIGGER mytrigger1 AFTER INSERT ON mytable
FOR EACH ROW
BEGIN
CALL fromulate_the_moobars(NEW.myid);
CALL its_peanut_butter_jelly_time(NEW.myname);
END//
