MySQL查询-语法错误

Question

The following code is an SQL query that I am using in PHP.

$sql = "INSERT INTO updates (update,user_id_fk) 
VALUES ('$post_update','$username')";

It does not work - I get the following error message when it is run.

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 'update,user_id_fk)

This syntax loks fine to me - it is the same as I found on W3Schools.

The mysql verion I am using is 5.5.24

Answer 1

update is a reserved keyword backtick it

INSERT INTO updates (`update`,user_id_fk) 

check the list below and in future do not use these words for your table or column names
