mysql Trigger for update nex column : Syntax error - mysql

i wat to create this trigger to set a defaul value for a clomn but i get this message 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 '' at line 4
this is my script :
CREATE TRIGGER trg_set_content_val BEFORE INSERT
ON post_table
FOR EACH ROW BEGIN
set NEW.content = 'mu value here';
END;

You need to set the delimiter to something else than semicolon before the stored program and then change it back:
DELIMITER //
CREATE TRIGGER trg_set_content_val
BEFORE INSERT
ON post_table
FOR EACH ROW BEGIN
set NEW.content = 'mu value here';
END//
DELIMITER ;
Reason:
If you use the mysql client program to define a stored program
containing semicolon characters, a problem arises. 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.
To redefine the mysql delimiter, use the delimiter command. The
following example shows how to do this for the dorepeat() procedure
just shown. The delimiter is changed to // to enable the entire
definition to be passed to the server as a single statement, and then
restored to ; before invoking the procedure. This enables the ;
delimiter used in the procedure body to be passed through to the
server rather than being interpreted by mysql itself.

MySql Syntax error when creating trigger to insert calculated value

This is my first time trying to create a MySql trigger but I'm running into syntax errors that I can't identify. I am trying to have the trigger insert a calculated value when a row is updated. Below is my code, but I keep getting syntax errors when I try to execute it, and I cannot see where the error is. Can someone please look, what am I doing wrong?
DROP TRIGGER ins_cop_dhw;
CREATE TRIGGER ins_cop_dhw BEFORE INSERT ON `2017010001_data`
FOR EACH ROW
BEGIN
IF (NEW.`_007E` = 1 AND `_00A2` > 0) THEN
SET NEW.`_00B7` = NEW.`_0096` / NEW.`_00A2`;
END IF;
IF (NEW.`_007D` = 1 AND `_00A2` > 0) THEN
SET NEW.`_00B8` = (NEW.`_0096` / NEW.`_00A2`);
END IF;
END;
Here is the error I get in MySQL Workbench, but it's not much help. :/
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 '' at line 5
MySQL Workbench highlights the end of line 6 as the start of the syntax error.
As said by #Akina I was missing the delimiter statements. Here is fixed code.
delimiter //
DROP TRIGGER ins_cop_dhw;
CREATE TRIGGER ins_cop_dhw BEFORE INSERT ON `2017010001_data`
FOR EACH ROW
BEGIN
IF (NEW.`_007E` = 1 AND NEW.`_00A2` > 0) THEN
SET NEW.`_00B7` = NEW.`_0096` / NEW.`_00A2`;
END IF;
IF (NEW.`_007D` = 1 AND NEW.`_00A2` > 0) THEN
SET NEW.`_00B8` = (NEW.`_0096` / NEW.`_00A2`);
END IF;
END//
delimiter ;
As per the advice of #Akina I read the Create Procedure documentation from the dev.mysql.com site and the below quote highlighted the importance of using delimiter
The example uses the mysql client delimiter command to change the statement delimiter from ; to // while the procedure is being defined. This enables the ; delimiter used in the procedure body to be passed through to the server rather than being interpreted by mysql itself. See Section 25.1, “Defining Stored Programs”.

MySQL Stored Procedure

I'm trying to create a stored procedure in MySQL using Sequel Pro but I keep getting the following 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
Please help
Below is my code:
DELIMITER //
CREATE PROCEDURE custname()
BEGIN
SELECT fname
FROM 062016_CustomerFile
END //
DELIMITER ;
You are missing a semi-colon after the table name.
DELIMITER //
CREATE PROCEDURE custname()
BEGIN
SELECT fname
FROM 062016_CustomerFile;
END //
DELIMITER ;
Note: your table name can be quoted (enclosed with backticks) but it is not required here.
From the documentation: Schema Object Names:
Identifiers may begin with a digit but unless quoted may not consist
solely of digits.

When Creating Trigger I got Error #1064 in Mysql 5

Error:

My Trigger
CREATE TRIGGER `register_notification_after_register`
`AFTER INSERT ON register FOR EACH ROW BEGIN
Set #notification = CONCAT('New Member Register. Membership Code is',' ',new.membership_no,'.');
Set #notificationfor =CONCAT('New Membership');
call notification_masterAddUpdate(1,#notification,#notificationfor,new.reg_date,1);
END
try this:
DELIMITER $$
CREATE TRIGGER `register_notification_after_register`
AFTER INSERT ON register FOR EACH ROW BEGIN
Set #notification = CONCAT('New Member Register. Membership Code is',' ',new.membership_no,'.');
Set #notificationfor =CONCAT('New Membership');
call notification_masterAddUpdate(1,#notification,#notificationfor,new.reg_date,1);
END
$$ -- I am done server, end of block
DELIMITER ;
you had an extra backtick on line two. One needs to set the DELIMITER to block the whole thing. With create event, create stored proc, create trigger, delimiters clue the server into when the whole chunk is done. Remember that the ; ends a statement. The delimiter statement suspends that in favor of something else, then resets at end of block

Syntax error in mysql new version

I have a problem with this, and I keep getting this 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 5.
Do you have any ideas for why I keep getting this error?
DROP PROCEDURE IF EXISTS `prn_insert`;
CREATE PROCEDURE `prn_insert`(id int, name text, description text)
BEGIN
insert into test
select id,name,description;
END
The semicolon is ending the CREATE PROCEDURE statement. To get the entire statement, use a delimiter other than a semicolon. We frequently use $$ (two dollar signs) as a delimiter, but you can use any character sequence that doesn't appear within the statement(s) you want to execute.
For example:
DELIMITER $$
DROP PROCEDURE myproc $$
CREATE PROCEDURE myproc(arg INT)
BEGIN
DECLARE i INT DEFAULT 0;
SET i = 1;
END$$
DELIMITER ;
Once the new delimiter is set, it stays in effect until it's changed to something else. So. we usually want to set it back to semicolon immediately after the `CREATE PROCEDURE' statement.

MySQL Event Scheduler syntax for insert and delete

I was wondering if you can tell me what's wrong with the ff sql statement:
insert into translog
select * from transponder_logs where trans_log_id < 150000;
delete from transponder_logs where trans_log_id < 150000
This statement ran just fine in sql but it gives me a syntax error when I used it on event scheduler.
The error message was:
"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 'delete from transponder_logs where trans_log_id < 150000 at line 3"
Whenever you define code like routines that have multiple executable statements, you MUST define a custom DELIMITER. And your code will be sent to the server along with delimiter instruction. And the server compiles the code as a block before it finds the newly defined custom delimiter.
Read what documentation says:
Defining Stored Programs
If you use the mysql client program to define a stored program containing semicolon characters, a problem arises. 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.
To redefine the mysql delimiter, use the delimiter command. .... The delimiter is changed to // to enable the entire definition to be passed to the server as a single statement, and then restored to ; before invoking the procedure. This enables the ; delimiter used in the procedure body to be passed through to the server rather than being interpreted by mysql itself.
I believe your event scheduler code is just executed as is without defining such delimiter.
Change it as following:
-- set the new delimiter
DELIMITER //
-- include your event scheduler code block here
-- lastly terminate the code block, with new delimiter
-- so that server starts compiling the code
//
-- now reset the delimiter to default
DELIMITER ;
