Create a new physical table manually in the repository, set the table type to "Select" and include your sql query.
Are you using a repository variable as input parameter? Assuming ADATE is a repository string variable, the syntax would be
select * from scheme.table_function1( 'valueof(ADATE)' )
You will have to manually add the columns to the new physical table and make sure they match with the sql results.
