ARRAY_ANY_MATCH

  • Returns TRUE if any element in the array is TRUE.
  • Returns FALSE if all elements in the array are FALSE or if the array is empty.
  • Returns NULL if any element is NULL and no element is TRUE.

When an optional lambda function is provided, ARRAY_ANY_MATCH applies the function to each element and then evaluates the resulting arrayt.

Alias: ANY_MATCH

Syntax 

{ ANY_MATCH | ARRAY_ANY_MATCH }([<expression> -> <condition>], <array> [, <array2>, ...])

Parameters

Parameter Description Supported input types  
  <expression> A lambda function applied to each element of the input arrays, returning a BOOLEAN. If no lambda function is provided, the function can only evaluate a single BOOLEAN array. For more information, see Manipulating arrays with Lambda functions. Same as the element data types of the input arrays.
  <condition> A BOOLEAN expression that evaluates each array value using a comparison operator. See Comparison operators.
  <array> The array to evaluate. ARRAY

Return Types

The ARRAY_ANY_MATCH function returns a result of type BOOLEAN.

Examples

Example The following code example checks if an array contains the value esimpson as the result is_he_playing:

SELECT ARRAY_ANY_MATCH(x -> x = 'esimpson', [ 'kennethpark', 'sabrina21', 'steven70']) AS is_he_playing;

Returns The previous code returns FALSE because the array does not contain the specified value:

is_he_playing (BOOLEAN)
f

Example The following code example checks if each element in the first array is divisible by the corresponding element in the second array in a result labeled divisible:

SELECT ARRAY_ANY_MATCH(x, y -> (x % y) = 0, [ 10, 20, 30, 45 ], [ 12, 3, 42, 15]) AS divisible;

Returns The previous code returns TRUE because each element in the first array is divisible by its corresponding element in the second array:

divisible (BOOLEAN)
t

Example The following code example evaluates multiple arrays using ARRAY_ANY_MATCH:

SELECT ARRAY_ANY_MATCH([])          as empty,
ARRAY_ANY_MATCH([true])         as single_true,
ARRAY_ANY_MATCH([false])        as single_false,
ARRAY_ANY_MATCH([NULL])         as single_null ,
ARRAY_ANY_MATCH([false, NULL])  as false_and_null;

Returns The previous code returns FALSE for the empty array, TRUE for the [TRUE] array, FALSE for the [FALSE] array, NULL for the [NULL] array, and FALSE for the [FALSE, NULL] array:

empty (BOOLEAN) single_true (BOOLEAN) single_false (BOOLEAN) single_null (BOOLEAN) false_and_null (BOOLEAN)
f t f NULL NULL
