Keywords


Each SQL statement contains one or more keywords. SQL is case insensitive to keywords, but throughout these manuals, keywords are indicated in upper case.

For example, in the following statement, SELECT and FROM are keywords:

SELECT *
FROM employee

The following statements are equivalent to the one above:

Select *
From employee
select * from employee
sELECT * FRoM employee

Some keywords cannot be used as identifiers without surrounding them in double quotes. These are called reserved words. Other keywords, such as DBA, do not require double quotes, and are not reserved words.
