What are the common uses of stored procedures?
Many databases use stored procedures and/or triggers to implementreferential integrity [ensuring that data referenced by another tabledoesn’t get deleted or updated in such a way as to compromise data integrity].Even databases that directly support referential integrity use stored proceduresand triggers for situations that can’t be handled with the “standard” options(Cascade, Set Default, Set Null, No Action).
Other uses of stored procedures include:
- moving global or commonly used procedures onto the server, resulting in improved performance
- optimizing and storing complex procedures to reduce run time overhead
- increased security (since users could be given authorization to invoke a stored procedure, but would not have authorization to directly affect the underlying data), to name a few.
