ANY and ALL

ANY and ALL are logical operators that let you make comparisons on subqueries that return one or more rows.

ANY and ALL are logical operators that let you make comparisons on subqueries that return one or more rows. Both operators must be preceded by a comparison operator and followed by a subquery:

expression comparison-operator { ANY | ALL } (subquery)

ANY returns true if the comparison between expression and any value returned by subquery evaluates to true.
ALL returns true only if the comparison between expression and all values returned by subquery evaluates to true.

Equivalent operators

You can use the following operators instead of ANY or ALL:

This operator...	Is equivalent to:
SOME	ANY
IN	= ANY
NOT IN	<> ALL

NULL handling

Vertica supports multicolumn <> ALL subqueries where the columns are not marked NOT NULL. If any column contains a NULL value, Vertica returns a run-time error.

Vertica does not support ANY subqueries that are nested in another expression if any column values are NULL.

Examples

Examples below use the following tables and data:

=> SELECT * FROM t1 ORDER BY c1;
 c1 | c2
----+-----
  1 | cab
  1 | abc
  2 | fed
  2 | def
  3 | ihg
  3 | ghi
  4 | jkl
  5 | mno
(8 rows)

=> SELECT * FROM t2 ORDER BY c1;
 c1 | c2
----+-----
  1 | abc
  2 | fed
  3 | jkl
  3 | stu
  3 | zzz
(5 rows)

ANY subqueries

Subqueries that use the ANY keyword return true when any value retrieved in the subquery matches the value of the left-hand expression.

ANY subquery within an expression:

=> SELECT c1, c2 FROM t1 WHERE COALESCE((t1.c1 > ANY (SELECT c1 FROM t2)));
 c1 | c2
----+-----
  2 | fed
  2 | def
  3 | ihg
  3 | ghi
  4 | jkl
  5 | mno
(6 rows)

ANY noncorrelated subqueries without aggregates:

=> SELECT c1 FROM t1 WHERE c1 = ANY (SELECT c1 FROM t2) ORDER BY c1;
 c1
----
  1
  1
  2
  2
  3
  3
(6 rows)

ANY noncorrelated subqueries with aggregates:

=> SELECT c1, c2 FROM t1 WHERE c1 <> ANY (SELECT MAX(c1) FROM t2) ORDER BY c1;
 c1 | c2
----+-----
  1 | cab
  1 | abc
  2 | fed
  2 | def
  4 | jkl
  5 | mno
(6 rows)

=> SELECT c1 FROM t1 GROUP BY c1 HAVING c1 <> ANY (SELECT MAX(c1) FROM t2) ORDER BY c1;
 c1
----
  1
  2
  4
  5
(4 rows)

ANY noncorrelated subqueries with aggregates and a GROUP BY clause:

=> SELECT c1, c2 FROM t1 WHERE c1 <> ANY (SELECT MAX(c1) FROM t2 GROUP BY c2) ORDER BY c1;
 c1 | c2
----+-----
  1 | cab
  1 | abc
  2 | fed
  2 | def
  3 | ihg
  3 | ghi
  4 | jkl
  5 | mno
(8 rows)

ANY noncorrelated subqueries with a GROUP BY clause:

=> SELECT c1, c2 FROM t1 WHERE c1 <=> ANY (SELECT c1 FROM t2 GROUP BY c1) ORDER BY c1;
 c1 | c2
----+-----
  1 | cab
  1 | abc
  2 | fed
  2 | def
  3 | ihg
  3 | ghi
(6 rows)

ANY correlated subqueries with no aggregates or GROUP BY clause:

=> SELECT c1, c2 FROM t1 WHERE c1 >= ANY (SELECT c1 FROM t2 WHERE t2.c2 = t1.c2) ORDER BY c1;
 c1 | c2
----+-----
  1 | abc
  2 | fed
  4 | jkl
(3 rows)

ALL subqueries

A subquery that uses the ALL keyword returns true when all values retrieved by the subquery match the left-hand expression, otherwise it returns false.

ALL noncorrelated subqueries without aggregates:

=> SELECT c1, c2 FROM t1 WHERE c1 >= ALL (SELECT c1 FROM t2) ORDER BY c1;
 c1 | c2
----+-----
  3 | ihg
  3 | ghi
  4 | jkl
  5 | mno
(4 rows)

ALL noncorrelated subqueries with aggregates:

=> SELECT c1, c2 FROM t1 WHERE c1 = ALL (SELECT MAX(c1) FROM t2) ORDER BY c1;
 c1 | c2
----+-----
  3 | ihg
  3 | ghi
(2 rows)

=> SELECT c1 FROM t1 GROUP BY c1 HAVING c1 <> ALL (SELECT MAX(c1) FROM t2) ORDER BY c1;
 c1
----
  1
  2
  4
  5
(4 rows)

ALL noncorrelated subqueries with aggregates and a GROUP BY clause:

=> SELECT c1, c2 FROM t1 WHERE c1 <= ALL (SELECT MAX(c1) FROM t2 GROUP BY c2) ORDER BY c1;
 c1 | c2
----+-----
  1 | cab
  1 | abc
(2 rows)

ALL noncorrelated subqueries with a GROUP BY clause:

=> SELECT c1, c2 FROM t1 WHERE c1 <> ALL (SELECT c1 FROM t2 GROUP BY c1) ORDER BY c1;
 c1 | c2
----+-----
  4 | jkl
  5 | mno
(2 rows)
