MySQL DELIMITER syntax errors

Question

This MySQL script installs multiple triggers.

It works on one machine running MySQL 5.0.51b-community. On another machine running MySQL 14.12 Distrib 5.0.45, for redhat-linux-gnu (i386) it fails, with this error message, which seems to be related to the DELIMITER // ... // DELIMITER; syntax :

ERROR 1064 (42000) at line 272: 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 'DELIMITER; DROP TRIGGER IF EXISTS trigger_name; DELIMITER' at line 1

The script syntax (summarised) is:

DROP TRIGGER IF EXISTS trigger_name;
DELIMITER //
CREATE TRIGGER trigger_name BEFORE UPDATE ON table
FOR EACH ROW BEGIN
  -- Trigger logic goes here
END //
DELIMITER;

-- More trigger drop/create statements follow

What is wrong with the script, and how can I correct it?

Answer 1

Try

DELIMITER ;

not

DELIMITER;

You're actually specifying ; as an argument to the DELIMITER command, so not having the space there may be confusing it.

Answer 2

You need a space between 'DELIMITER' and ';'

DELIMITER ;
# not:
DELIMITER;

Answer 3

Just as an add-on, for someone else:

The delimiter is required to enable the entire definition to be passed to the server as a single statement.

Answer 4

In the version of MySql I use the same error occurs when using the delimiter command, but this version handles the delimiter ";" for statements and delimiter "|" for stored procedures and functions, which i think solves the problem; try this:

DROP TRIGGER IF EXISTS trigger_name;

CREATE TRIGGER trigger_name BEFORE UPDATE ON table FOR EACH ROW BEGIN -- Trigger logic goes here END |

-- other statements or functions here

Answer 5

Hmm I'm having similar problems. I do a mysqldump from Debian Lenny running 5.0.51 and try importing to OpenSolaris running 5.0 and get the same error. And I have DELIMITER ;

Version conflict?

Answer 6

Try the below.

I am sure it should solve the purpose.

DELIMITER +
CREATE TRIGGER STUDENT_INSERT_TRIGGER BEFORE INSERT ON FSL_CONNECTIONS 
FOR EACH ROW BEGIN 
INSERT INTO STUDENT_AUDIT 
SET STUDENT_ID = NEW.STUDENT_ID, 
MAC_ADDRESS = NEW.MAC_ADDRESS,
IPADDRESS = NEW.IPADDRESS, 
EMAIL_ID = NEW.EMAIL_ID , 
START_TIME=NEW.START_TIME, 
END_TIME=NEW.END_TIME, 
STATUS=NEW.STATUS; 
END; +

From the above when we use a DELIMITER. It should be in the form of

DELIMITER +
