Why doesn't the Oracle optimizer use my index?
Querying too much data
Most Oracle developers know that an index is useful when you can use it to restrict your result set to a small number of the total rows in a table.

Using SQL Scripts we can save all the SQL queries as files that we use very frequently on our database later point of time. This is one of the feature present under SQL Workshop in Oracle Application Express.
