- 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:
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:
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 |
