Reserved Words, Keywords, and Namespaces

Topics in this appendix include:

Reserved Words and Keywords

Some words are reserved by Oracle. That is, they have a special meaning to Oracle and cannot be redefined. For this reason, you cannot use them to name database objects such as columns, tables, or indexes. To view the lists of the Oracle reserved words for SQL and PL/SQL, see the Oracle9i SQL Reference and the PL/SQL User's Guide and Reference.

Like COBOL keywords, you cannot use Pro*COBOL keywords as variables in your program(s). Otherwise, an error will be generated. An error may result if they are used as the name of a database object such as a column. Here are the keywords used in Pro*COBOL.

Reserved Namespaces

Table C-1 contains a list of namespaces that are reserved by Oracle. The initial characters of subprogram names in Oracle libraries are restricted to the character strings in this list. Because of potential name conflicts, use subprogram names that do not begin with these characters.

For example, the Oracle Net Transparent Network Service functions all begin with the characters "NS," so avoid writing subprograms with names beginning with "NS."
