What is the purpose of init.ora. ?
this is used for the start up and maintanence of the
databse also for security purposes.u can hv only 1 init.ora
per database.
what is a fuction based index?
There will be some situation where u always use two colums
of a table in a querey(always combined) for getting rows or
getting some fn ie:getting sal+comm point of a
employee.what we usually do is creating 2 indexes seperately
for sal and comm point.instead u write a fn for adding sal
+comm pt and creating index for that.hope u will be clear
now.but unless and until ur data results is large dont use
it.
