MySQL rejecting parameter

问题

Ok, I'm going crazy on this one. MySQL is throwing a fit about this bit of SQL:

INSERT INTO `test_table` 
  ( `column1`, `column2` ) 
VALUES 
  ( ?COURSEID, ?COURSENAME )

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 'COURSENAME )' at line 1

My debug code is showing both of the parameter values filled.

回答1:

MySQL does not support named parameter placeholders. You can use only positional parameter placeholders. That is, a placeholder is just a ? symbol.

This conforms to the ANSI SQL behavior, by the way. RDBMS like Oracle support named parameters as an extension to the standard.

回答2:

Not sure if that will work. I would change to either

VALUES (?, ?)

OR

VALUES (:COURSEID, :COURSENAME)
