I Want to Use Sequence.NEXTVAL & Sequence.CURRVAL throughout the package. How can i declare the global sequence variable and make them available for all the stored procedures inside the package ?
Any help highly appreciated..
Thank you all in advance

No i know that but using directly SEQUENCE.CURRVAL inside the Insert statement is not a good practice.
We need to declare inside the procedure a variable and then fetch the SEQUENCE.CURRVAL into that variable
and use that variable inside the insert statement. But we that variable scope will be available only inside that procedure.
if i want the same CURRVAL in another stored procedure. How can i get it ..that is my Question.What exactly are you trying to achieve?
If it's a case of needing to know the value of the sequence number assigned to an inserted record you would typically use the RETURNING clause on the insert statement...
