There are no words that are specifically reserved words in DB2 Version 7.
Keywords can be used as ordinary identifiers, except in a context where they could also be interpreted as SQL keywords. In such cases, the word must be specified as a delimited identifier. For example, COUNT cannot be used as a column name in a SELECT statement unless it is delimited.
IBM SQL and ISO/ANSI SQL92 include reserved words, listed in the following section. These reserved words are not enforced by DB2 Universal Database, however it is recommended that they not be used as ordinary identifiers, since this reduces portability.
