Hi
The following is the quote describing WHERE clause of SELECT
(pgsql/doc/html/sql-select.html).
"WHERE Clause
The optional WHERE condition has the general form:
WHERE boolean_expr
boolean_expr can consist of any expression which evaluates to a boolean value. In many
cases,
this expression will be:
expr cond_op expr
or
log_op expr
where cond_op can be one of: =, <, <=, >, >= or <>, a conditional operator like ALL,
ANY, IN,
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
LIKE, or a locally defined operator, and log_op can be one of: AND, OR, NOT. SELECT
will ignore
all rows for which the WHERE condition does not return TRUE. "
Please give me hints how can I use "conditional operators ALL, ANY" in
WHERE clause.
Some examples will be appreciated.
Thanks in advance.
