Hi,
I want to concat multiple columns into a single column after grouping the
DataFrame,
I want an functional equivalent of Redshift ListAgg function
pg_catalog.Listagg(column, '|')
within GROUP( ORDER BY column) AS
name
LISTAGG Function
: For each group in a query, the LISTAGG aggregate function orders the rows
for that group according to the ORDER BY expression, then concatenates the
values into a single string.
