In MySQL, certain words like SELECT, INSERT, DELETE, and KEY are reserved words. Reserved words have special meaning within the database and cannot be used as table names, column names, or other identifiers unless you quote them with backticks (`).
The following query will result in a syntax error because KEY is a reserved word in MySQL:
<br>INSERT INTO user_details (username, location, key)<br>VALUES ('Tim', 'Florida', 42)<br>
To fix the issue, you can either avoid using reserved words as table or column names or wrap the reserved word in backticks when referring to it. Here's how:
The simplest solution is to use a different name for the column that is not a reserved word.
If you must use a reserved word, wrap it in backticks. For example, to fix the query above, change:
<br>key<br>
to:
<br>key<br>
The resulting query will be:
<br>INSERT INTO user_details (username, location, key)<br>VALUES ('Tim', 'Florida', 42)<br>
