How Do I Escape Reserved Keywords Like 'order' When Creating MySQL Table Names?

Escaping Reserved Keywords in SQL Table Names

When working with MySQL, certain words are reserved and cannot be used as table names without special handling. One such reserved word is "order." Attempting to use it as a table name without escaping will result in an error.

Resolving the Error with Escape Characters

To avoid this error, table names containing reserved keywords must be enclosed in escape characters. In MySQL, the backticks ( ) are commonly used for this purpose. So, to query the table named "order," you should write:

mysql_query("SELECT * FROM `order` WHERE orderID = 102;");

Avoiding Reserved Keywords

While escaping can resolve the error, it is generally advisable to avoid using reserved keywords as table or field names. This helps prevent unexpected behaviors and errors in the future.
