{ } Braces
Braces enclose required syntax items. For example:
FROM { grantee[, grantee]...}
A group of items enclosed in braces is a list from which you are required to choose one item.
The items in the list can be arranged either vertically, with aligned braces on each side of the
list, or horizontally, enclosed in a pair of braces and separated by vertical lines. For example:
INTERVAL { start-field TO end-field }
{ single-field }
INTERVAL { start-field TO end-field | single-field }
| Vertical Line
A vertical line separates alternatives in a horizontal list that is enclosed in brackets or braces.
For example:
{expression | NULL}
… Ellipsis
An ellipsis immediately following a pair of brackets or braces indicates that you can repeat
the enclosed sequence of syntax items any number of times. For example:
ATTRIBUTE[S] attribute [, attribute]...
{, sql-expression}...
An ellipsis immediately following a single syntax item indicates that you can repeat that
syntax item any number of times. For example:
expression-n…
Punctuation
Parentheses, commas, semicolons, and other symbols not previously described must be typed
as shown. For example:
DAY (datetime-expression)
@script-file
Quotation marks around a symbol such as a bracket or brace indicate the symbol is a required
character that you must type as shown. For example:
"{" module-name [, module-name]... "}"
Item Spacing
Spaces shown between items are required unless one of the items is a punctuation symbol
such as a parenthesis or a comma. For example:
DAY (datetime-expression)
DAY(datetime-expression)
If there is no space between two items, spaces are not permitted. In this example, no spaces
are permitted between the period and any other items:
myfile.sh
