This section lists the typographic and graphical conventions used in this documentation.

Syntax conventions The following conventions are used in the SQL syntax descriptions:

♦Keywords All SQL keywords appear in upper case, like the words ALTER TABLE in the following example:

ALTER TABLE [ owner.]table-name

♦Placeholders Items that must be replaced with appropriate identifiers or expressions are shown like the words owner and table-namein the following example:

ALTER TABLE [ owner.]table-name

♦Repeating items Lists of repeating items are shown with an element of the list followed by an ellipsis (three dots), like column-constraintin the following example:

ADD column-definition [ column-constraint , . . . ]

One or more list elements are allowed. In this example, if more than one is specified, they must be separated by commas.

♦Optional portions Optional portions of a statement are enclosed by square brackets.

RELEASE SAVEPOINT [ savepoint-name]

These square brackets indicate that the savepoint-nameis optional. The square brackets should not be typed.

♦Options When none or only one of a list of items can be chosen, vertical bars separate the items and the list is enclosed in square brackets.

[ ASC DESC ]

For example, you can choose one of ASC, DESC, or neither. The square brackets should not be typed.

♦Alternatives When precisely one of the options must be chosen, the alternatives are enclosed in curly braces and a bar is used to separate the options.

[ QUOTES { ON OFF } ]

If the QUOTES option is used, one of ON or OFF must be provided. The brackets and braces should not be typed.
