I am using php/mysql


UC is email1

INSERT INTO renters (first_name,last_name,email1,email2,email3,phone1,phone2,phone3,information,description) VALUES ('TEST','','derrickjmiller1@gmail.com','','','','','','','
\r\n	ADD THIS PLEASE

\r\n') ON DUPLICATE KEY UPDATE renters set description=concat (description,'
\r\n	ADD THIS PLEASE

\r\n');

Open in new window


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 'set description=concat (description,' \r\n ADD THIS PLEASE  \r\n')' at line 1

Well your query isn't quite finished in the code you posted. This should do it:

ON DUPLICATE KEY UPDATE renters set description=concat (description,'somthing to add to description')";

Open in new window

what is difference between your code

ON DUPLICATE KEY UPDATE renters set description=concat (description,'somthing to add to description')";

and

INSERT INTO renters (first_name,last_name,email1,email2,email3,phone1,phone2,phone3,information,description) VALUES ('TEST','','derrickjmiller1@gmail.com','','','','','','','
\r\n      ADD THIS PLEASE

\r\n') ON DUPLICATE KEY UPDATE renters set description=concat (description,'
\r\n      ADD THIS PLEASE

\r\n');

your syntax is wrong.
instead of adding the table name again,
ON DUPLICATE KEY UPDATE renters set description=concat (description,'
 it should be
ON DUPLICATE KEY UPDATE  description=concat (description,'
