ARRAY_AGGREGATE (Lakehouse v1)

Aggregates elements in the array with an aggregate function.

Analyze Syntax

func.array_aggregate( <array>, '<agg_func>' )

• Supported aggregate functions include avg, count, max, min, sum, any, stddev_samp, stddev_pop, stddev, std, median, approx_count_distinct, kurtosis, and skewness.

• The syntax can be rewritten as func.array_<agg_func>( <array> ). For example, func.array_avg( <array> ).

Analyze Examples

func.array_aggregate([1, 2, 3, 4], 'sum'), func.array_sum([1, 2, 3, 4])
