Specifies whether a double quote delimiter should be used in DDL statements to identify objects such as schemas, tables, etc.

Unquoted identifiers are case-insensitive. This means that they will recognize customer, Customer, and CUSTOMER as the same object. However, quoted identifiers are case-sensitive. This leads to treating "CUSTOMER" and "customer" as entirely different objects.

You should keep in mind that XDM uses double quote delimiters by default. Turning this feature off can lead to usability issues. If you decide not to use double quote delimiters, you should be aware of how the database you are dealing with handles identifiers. For example, Db2 converts unquoted identifiers to uppercase, whereas PostgreSQL converts them to lowercase. You should avoid mixing tasks with and without double quote delimiters.
