The names of DB objects are automatically converted into uppercase letters when entered. If you wish to define object names containing lowercase letters or special characters, you must enclose these characters in double quotation marks. The object name does not appear in the specified form until you enter the first double quotation mark. Object names identical to a keyword must also be enclosed in double quotation marks.
The object names or search patterns are specified without double quotation marks in dialog boxes where search patterns are entered. In this case, the characters are case sensitive.
