What is a stored procedure and what are its advantages and disadvantages?
Advantage: Stored procedures can be used to maintain data integrity and enforce database policy without relying on an external program to do so. Disadvantage: Can make debugging more complex. Can also be sensitive to being dropped during copy operations, if not done correctly.
What is a stored procedure and why is it particularly useful?
A stored procedure is a named block of PL/SQL and SQL statements. One of the major advantages of stored procedures is that they can be used to encapsulate and represent business transactions.
