What is pragma restrict_reference in oracle 9i?When we use this?Give me one realtime scenario?..

Answer / bhaskar gouda

First of all ,it is a compiler directive,This is introduced
to avoid the side affect of the function in a package .it
comes in 4 flavors.RNDS,WNDS,RNPS,WNPS.
each out of the above 4 can be implemented against the
packaged function.

If you want the function not to alter the contents of any
database table than you can use WNDS.similarly if you want
the function not to read the contents of any database table
you can use RNDS.If you want the function not to alter any
variables within another package than you can use WNPS.If
you want the packaged function not to read the variables
within another package than you can use RNPS.

Answer / shail

Obsolete in 10g and onwards. Oracle take care at its own.
The reply from Raphael Fernandes is misleading. This type
of misleading replies can cost a interview of a candidate.
Request all to not reply if you are not sure.

Answer / m.nihar

The RESTRICT_REFERENCES pragma asserts that a user-defined subprogram does not read or write database tables or package variables.Subprograms that read or write database tables or package variables are difficult to optimize, because any invocation of the subprogram might produce different results or encounter errors.

Answer / raphael fernandes

pragma restrict_reference is used to associate a user
defined exception to an oracle error. Whenever the
associated error occurs in the pl/sql code, the exception
is raised implicitly by Oracle.
