The expressions do not all need to evaluate to the same data type. Returns¶ The data type of the returned value is ARRAY. Usage Notes¶ SQL NULL values are skipped when building the result array, resulting in a compacted (i.e. dense) array. Examples¶Takes an ARRAY value as input and returns the size of the array (i.e. the largest index + 1). If the array is a sparse array, this means that the size includes the undefined elements as well as the defined elements. A NULL argument returns NULL as a result.
