The first COMBO function combines two integers by adding them and returns the sum. The second COMBO function combines three integers the same way. The third COMBO function combines two character strings by concatenating them. The standard allows both of these functions named COMBO to be defined at the same time within the database. When the DBMS encounters a reference to the COMBO function, it examines the number of arguments in the reference and their data types, and determines which version of the COMBO function to call. Thus, the overloading capability allows a SQL programmer to create a family of routines that logically perform the same function and have the same name, even though the specifics of their usage for different data types is different. In object-oriented terms, overloading is sometimes called polymorphism, meaning literally that the same function can take many different forms. To simplify the management of a family of routines that share an overloaded name, the SQL/PSM standard has the concept of a specific name: a second name that is assigned to the routine that is unique within the database schema or module. It uniquely identifies a specific routine. The specific name is used to drop the routine, and it is reflected in the Information Schema views that describe stored routines. The specific name is not used to call the routine; that would defeat the primary purpose of the overloaded routine name. Support for specific names or some similar mechanism is a practical requirement for any system that permits overloading or polymorphism for objects and provides a capability to manage them by dropping or changing their

The bulk of the SQL/PSM standard is concerned with the extensions to the SQL language that are used to define SQL-procedures and SQL-functions. Note, however, that the method used to invoke a SQL-procedure (the CALL statement) or a SQL-function (a reference to the function by name within a SQL statement) are not particular to procedures defined in the SQL language. In fact, the SQL/PSM standard provides for external stored procedures and functions, written in some other programming language such as C or Pascal. For external procedures, the CREATE PROCEDURE and CREATE FUNCTION statements are still used to define the procedure to the DBMS, specifying its name and the parameters that it accepts or returns. A special clause of the CREATE statement specifies the language in which the stored procedure or function is written, so that the DBMS may perform the appropriate conversion of data types and call the routine appropriately.

The SQL/PSM standard treats SQL-procedures and SQL-functions as managed objects within the database, using extensions to the SQL statements used to manage other objects. You use a variation of the DROP statement to delete routines when they are no longer needed, and a variation of the ALTER statement to change the definition of a function or procedure. The SQL2 permissions mechanism is similarly extended with additional privileges. The EXECUTE privilege gives a user the ability to execute a stored procedure or function. It is managed by the GRANT and REVOKE statements in the same manner as other database privileges. Because the stored routines defined by SQL/PSM are defined within SQL2 schemas, many routines can be defined in many different schemas throughout the database. When calling a stored routine, the routine name can be fully qualified to uniquely identify the routine within the database. The SQL/PSM standard provides an alternative method of searching for the definition of unqualified routine names through a new PATH concept. The PATH is the sequence of schema names that should be searched to resolve a routine reference. A default PATH can be specified as part of the schema header in the CREATE SCHEMA statement. The PATH can also be dynamically modified during a SQL session through the SET PATH statement. The SQL/PSM standard also lets the author of a stored procedure or function give the DBMS some hints about its operation to improve the efficiency of execution. One example is the ability to define a stored routine as DETERMINISTIC or NOT DETERMINISTIC. A DETERMINISTIC routine will always return the same results when it is called with the same parameter values. If the DBMS observes that a DETERMINISTIC routine is called repeatedly, it may choose to keep a copy of the results that it returns. Later, when the routine is called again, the DBMS does not
