The table in this chapter lists keywords, words reserved from use in SQL programs and isql (Interactive SQL). The list includes DSQL, isql, and gpre keywords.
Keywords are defined for special purposes, and are sometimes called reserved words. A keyword cannot occur in a user-declared identifier or as the name of a table, column, index, trigger, or constraint, unless it is enclosed in double quotes. Keywords are:
- Part of statements
- Used as statements
- Names of standard data structures or data types
