CREATE TRIGGER agecheck AFTER INSERT ON student
FOR EACH
ROW
BEGIN
IF (CURRENT_DATE-Dateofbirth) > 16
THEN dbms_output.put_line('Age must be greater than 16');
END IF;
END;
I am trying to write this trigger in phpmyadmin but it gives an error on dbms_output.put_line. It says "you have an error in your sql syntax". Can anyone please help me out with this?
dbms_output.put_line is an Oracle pl/sql call, it is not available in mysql. There is no direct equivalent in mysql's procedural language. The closest thing to this call is perhaps SIGNAL command with class 01 (warning) or you can create a table into which the trigger can insert its messages.

I've been trying to create a simple BEFORE INSERT trigger on a database table (MySQL v 5.7 ) but I keep receiving a vague "#1064 ... syntax error" message which doesn't help resolve the issue.
Here's the SQL:
CREATE OR REPLACE TRIGGER `CREATE_QUIZ_TRIG` BEFORE INSERT ON `quiz`
FOR EACH ROW BEGIN
SET NEW.ACTIVE = UPPER(NEW.ACTIVE);
SET NEW.CREATED = NOW();
END
/
All I'm trying to do is enforce a column to uppercase and then insert the current date & time into a timestamp column. I've been following the documentation from:
https://dev.mysql.com/doc/refman/5.7/en/trigger-syntax.html
and realise that for multi-statement expression I have to redefine the delimiter at the beginning of the trigger's creation but the same '#1064' error occurs.
This is made even more confusing because when I use phpmyadmin's interface for creating the same trigger it works fine - but won't when I export the generated SQL and try to create the trigger using that!?
Thanks for any help
I didn't realise that, by default, phpmyadmin adds a ; delimiter which was breaking the ; used to end a statement within the BEGIN END block.
Here i am trying to insert into payment_table after updating the review_table only after the status in review_table is updated to 2 .But there is error after running this trigger i.e,
1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the
Trigger is:
CREATE TRIGGER payment_details_trig AFTER UPDATE ON review_table
FOR EACH ROW
BEGIN
IF NEW.status=2
INSERT INTO payment_table(paper_id, payment_mode, payment_refNo, payment_image,status)
VALUES (0,0,0,0,0);
END IF;
END;
Nothing sticks out except for the missing THEN. You might need delimiter statements:
DELIMITER $$
CREATE TRIGGER payment_details_trig AFTER UPDATE ON review_table
FOR EACH ROW
BEGIN
IF NEW.status = 2 THEN
INSERT INTO payment_table(paper_id, payment_mode, payment_refNo, payment_image,status)
VALUES (0, 0, 0, 0, 0);
END IF;
END;
$$
DELIMITER ;
The issue 1064 in SQL comes in following four cases:
1) Use of reserved words:
Every version of MySQL has its own list of reserved words. These are words that are used for specific purposes or perform specific functions within the MySQL engine. If you attempt to use one of these reserved words, you will receive the 1064 error.To fix the issue, you will want to surround the word with backticks “`”.
2) Missing Data:
Sometimes data in the database is missing. This can cause issues when this data is required for a query.
3) Mistyped or missing Commands:
One of the most common causes for the 1064 error is when a SQL statement uses a mistyped or missing command.
4) Deprecated Commands:
Some commands that were deprecated (slated for removal but still allowed for a period of time) eventually go obsolete. This means that the command is no longer valid in the SQL statement.
In your case third option is the answer is the reason of your error. You have missed writing THEN after IF.
CREATE TRIGGER question_preserver BEFORE UPDATE ON bank
FOR EACH ROW
BEGIN
IF TRIM(NEW.question) != TRIM(OLD.question) THEN
INSERT INTO bank_question_history (id,old_question) VALUES (OLD.id,OLD.question)$$
END IF$$
END$$
I am inserting that query into Mysql using PHPMyAdmin's SQL window, using a delim of $$. I get an 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 5
I'm sure it's something obvious and I'm just missing it, but no matter what I try I can't get it to work. The error is not helpful at all, and from what I have researched I am doing this exactly like 4-5 examples I found.
Any help would be greatly appreciated, thank you!
Go figure I figured it out right after asking.
CREATE TRIGGER question_preserver BEFORE UPDATE ON bank
FOR EACH ROW
BEGIN
IF TRIM(NEW.question) != TRIM(OLD.question) THEN
INSERT INTO bank_question_history (id,old_question) VALUES (OLD.`id`,OLD.`question`);
END IF;
END$$
You have to use ; to break each statement/command and your delim $$ to end the entire trigger.
Being a complete newbie to this, I thought I might be able to save my self a lot of headache by just asking for help...
When I try to run this I'm getting an Error 1064: You have an error in your SQL Syntax...
CREATE TRIGGER payroll_lock BEFORE DELETE OR INSERT OR
UPDATE ON timesheet_entry FOR EACH ROW IF entry_date < '2013-07-25'
THEN raise_application_error(-20001, 'Cannot modify old records.');
I would also consider other options for stopping the insert/update/delete if the record is before a given fixed date.
Thanks for any help in fixing this! And explanations are appreciated, I don't know much in this particular area.
you should CALL keyword before raise_application_error function.
another tip is you should use NEW or OLD keyword for update trigger.
I'm not sure but I don't think you can create multiple trigger at same command with OR(this is first time I see that).
DELIMITER //
CREATE TRIGGER payroll_lock BEFORE UPDATE ON wp_links
FOR EACH ROW
BEGIN
IF NEW.entry_date < '2013-07-25' THEN
CALL raise_application_error(-20001, 'Cannot modify old records.');
END IF;
END//
Need some help for this error message that appears on delphi 7
First, i will describe some script:
On mySQL procedure script:
CREATE PROCEDURE ActualStok()
NOT DETERMINISTIC
CONTAINS SQL
SQL SECURITY DEFINER
COMMENT ''
BEGIN
SELECT B.KD_BRG, B.NAMA_BRG, B.UKURAN, B.SATUAN,
(B.JUMLAH_BRG-(SELECT IFNULL(SUM(D.JUMLAH_PAKAI_BRG),0)
FROM DETAIL_PAKAI_BRG D
WHERE (D.STATUS_AMBIL='0') AND (D.KD_BRG=B.KD_BRG) AND (D.UKURAN=B.UKURAN)
AND (D.SATUAN=B.SATUAN))),
B.KETERANGAN_BRG
FROM BARANG B;
END;
Then i check that procedure --> CALL ActualStok();
And it's work. mySQL show me the expected result, and fine. There is no error.
So on delphi program, i try to execute this script:
procedure TFrmPersediaan.Button1Click(Sender: TObject);
begin
FrmDtm.ADOQBarang.Close;
FrmDtm.ADOQBarang.SQL.Clear;
FrmDtm.ADOQBarang.SQL.Add('CALL ActualStok()');
FrmDtm.ADOQBarang.Open;
end;
Delphi shows me a error message "Multiple-step operation generated errors. Check each status value."
Please somebody to help me to solve this problem.
Thank you for any participant.
This might due to unsupported date values by ADO. In my case the error was caused by date value 01-01-0020 in my Oracle database, which isn't recognized by ADO.
