This example shows how to use ARRAY_AGG () to pivot a column of output into an array in a single row: This example shows the use of the DISTINCT keyword with ARRAY_AGG (). This example uses two separate ORDER BY clauses, one of which controls the order within the output array inside each row, and one of which controls the order of the output rows: This example shows how to use ARRAY_AGG () to pivot a column of output into an array in a single row: This example shows the use of the DISTINCT keyword with ARRAY_AGG (). This example uses two separate ORDER BY clauses, one of which controls the order within the output array inside each row, and one of which controls the order of the output rows: select 12.3::FLOAT::NUMBER(3,2); Copy.
