Reserved words

Some keywords in SQL are also reserved words. To use a reserved word in a SQL statement as an identifier, you must enclose it in double quotes. Many, but not all, of the keywords that appear in SQL statements are reserved words. For example, you must use the following syntax to retrieve the contents of a table named SELECT.


Because SQL is not case sensitive with respect to keywords, each of the following words may appear in uppercase, lowercase, or any combination of the two. All strings that differ only in capitalization from one of the following words are reserved words.

If you are using embedded SQL, you can use the sql_needs_quotes database library function to determine whether a string requires quotation marks. A string requires quotes if it is a reserved word or if it contains a character not ordinarily allowed in an identifier.

For more information, see sql_needs_quotes function.

The reserved SQL keywords in SQL Anywhere are as follows:
