sql server - Returning different tables based on parameter? -

-

for example, have function returns table columns follows:

returns table (a character varying, b boolean, c numeric)

then based on parameter result_mode default 'summary', want return different table follows:

returns table (a timestamptz, b boolean, c character varying, d numeric)

originally have stored procedure in ms sql return results 'summary', 'customer item summary', 'item summary' etc. in postgresql, different think.

i might need create multiple functions if can't fit them 1 single function.

so, possible sort of have if-statement or case statement returns table based on parameter input?
