string_agg(expr: string, delimiter: const string, [order_by(...)]?) -> string

Returns concatenated input values, separated by the delimiter.

The expression must be a string column. The delimiter must be a string constant (it may be an empty string). If no ordering is specified, the default ordering is that of the invoking verb, which is generally the 'valid_from' timestamp, ascending.
