I am trying to create a dump of an Oracle 9i schema. I know how to create a .dmp file that includes all of the tables in the schmea but the problem is I want to exclude 2 tables from the dump file. Well that is not entirely true. I want the table structures to come along just not the data.
Have you ever had to make fundamental changes to a table in Oracle, but haven't been able to get any downtime? I'm talking things like:
* Dropping columns
* Shrinking allocated space
* Removing chained blocks and restoring the PCTFREE
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.
