This section describes the components
that are used in SQL procedure statements. Components are the items
in PROC SQL syntax that appear in roman type.
Most components are
contained in clauses within the statements. For example, the basic
SELECT statement includes the SELECT and FROM clauses, where each
clause contains one or more components. Components can also contain
other components.
For easy reference,
components appear in alphabetical order, and some terms are referred
to before they are defined. Use the index or the “See Also”
references to refer to other statement or component descriptions that
might be helpful.
