The LISTAGG function is used to aggregate a set of string values within a group into a single string by appending the string-expression values based on the order that's specified in the 'WITHIN GROUP' clause.

As a group-set aggregate, the function operates on and returns an output row for each group defined by the GROUP BY clause. As an analytic function, LISTAGG partitions the query result set into groups based on one or more expression in the query_partition_clause.
