i think these upper suggestions are right ,
IF NOT then What is your suggestion??You have not said whether you want to fetch a single row or fetch multiple rows. The reasons will differ. The method used will differ.
For example, you have a parameter table for an application. The application needs a call that returns a specific parameter value from the table. Or you have an Invoicing Shipping and Billing process that needs all invoices with the same shipping zip code in order to create the most cost effective shipping orders for the goods. It needs a call that will return a non-processed invoice data set with the same zip code.
Both are very different business needs. One does a single row fetch always. The other does anything from fetching a single invoice to 1000's of invoices.
These will be implemented very differently. There is not single processing and cursor approach for all problems in PL/SQL. The HOW it is done depends on the WHAT needs to be done.
As for fetching multiple rows - that is best done using bulk fetching. This provides the least amount of context switches between the PL/SQL and SQL engines. The basic sample template for bulk fetching is demonstrated in {message:id=9651210}.
