Read loops from right to left.
The following conventions apply to loops:
Loop Convention
A maximum number of entries is
allowed.
A minimum number of entries is
required.
A separator character is required
between entries.
A delimiter character is required
around entries.
Description
The number appears in a circle on the return path.
In the example, you may type cname a maximum of 4 times.
The number appears in a square on the return path.
In the example, you must type at least three groups of column
names.
The character appears on the return path.
If the diagram does not show a separator character, use one
blank space.
In the example, the separator character is a comma.
The beginning and end characters appear outside the return
path.
Generally, a space is not needed between delimiter characters
and entries.
In the example, the delimiter characters are the left and right
parentheses.
Excerpts
Sometimes a piece of a syntax phrase is too large to fit into the diagram. Such a phrase is
indicated by a break in the path, marked by (|) terminators on either side of the break. The
name for the excerpted piece appears between the terminators in boldface type.
