get(array, index)

​

Arguments

• T is the array element type: BOOLEAN, TINYINT, SMALLINT, INTEGER, BIGINT, FLOAT, DOUBLE, DECIMAL(p, s), STRING, BINARY, DATE, TIME, TIMESTAMP, ARRAY, MAP or STRUCT.

​

Returns

• Type: T
• Possible values: The selected element.
• NULL behavior: Returns NULL for NULL inputs, a NULL selected element, negative index, or an index beyond the end.

Usage notes

• INTEGER and INT mean the same type; STRING means VARCHAR text. NULL can be used with a supported type. Cast NULL explicitly when its type would otherwise be unclear.
