You need to use a paramaterized view. Client server networks are designed
to return a small subset of data, not the entire table contents. If you
have a paramerized view set up to use a primary key you should be returning
a single row. Since a PK uses an index, the response time will be much
better than pulling down the entire table (sub second versus 30 mintues).

Even in the case of using a foreign key returning say a 1,000 rows (again
assuming the column is indexed) the respons time should not take more than 2 seconds.
