Snowflake array length
array_size¶. 入力配列のサイズを返します。 array_size のバリエーションは、入力として variant 値を取ります。variant 値に配列が含まれる場合、配列のサイズが返されます。それ以外の場合、値が配列でない場合は null が返されます。length . Returns the number of items in the array. The result type is UInt64. The function also works for strings. Can be optimized by enabling the optimize_functions_to_subcolumns setting. With optimize_functions_to_subcolumns = 1 the function reads only size0 subcolumn instead of reading and processing the whole array column. The query …

You can then call ARRAY_SIZE to get the count of values. This approach works for values of any data type (e.g. VARIANT) and does not require “bucketizing”, unless the size of the data in the ARRAY exceeds the maximum size of an ARRAY.

The return value is 0-based, not 1-based. In other words, if the variant_expr matches the first element in the array, this function returns 0, not 1. If the VARIANT value is not contained in the ARRAY, the function returns NULL. If you specify NULL for variant_expr, the function returns the position of the first NULL in the array.Semi-structured Data Types. VARIANT. OBJECT. ARRAY. Geospatial Data Types. GEOGRAPHY. GEOMETRY.

Contiguous split strings in the source string, or the presence of a split string at the beginning or end of the source string, results in an empty string in the output. An empty separator string results in an array containing only the source string.Though this approach will explode really fast size_array_1 * size_array_2 * size_array_3.
