ARRAY_APPENDAppends an element to the end of an array.
ARRAY_AVGReturns the average of all non-null elements of a list.
ARRAY_CATReturns a concatenation of two arrays.
ARRAY_COMPACTReturns the input array without null values.
ARRAY_CONTAINSReturns whether a list contains a given value.
ARRAY_DISTINCTGiven an input array, returns an equivalent array that includes only distinct elements.
ARRAY_GENERATE_RANGEReturns an array of integers in the specified range.
ARRAY_INSERTReturns an array that contains all of the elements from the input array as well as a new element inserted in the specified position.
ARRAY_MAXReturns the maximum value of a list.
ARRAY_MINReturns the minimum value of a list.
ARRAY_POSITIONReturns the index of the first occurrence of an element in an array.
ARRAY_PREPENDPrepends an element to the beginning of an array.

MAP_KEYSReturns all keys from a map expression.
MAP_VALUESReturns all values from a map expression.
SET_UNIONGiven two arrays, returns a single array that includes all of the elements in the given arrays, without duplicates.
SUBLISTReturns an array constructed from the specified subset of elements of the input array.
