A stored procedure can return multiple values using the OUT parameter, or return no value. A stored procedure saves the query compiling time. A stored procedure is a database object. A stored procedure is a material object.
A database object is a structure for storing, managing and presenting application- or user-specific data in a database. Depending on the database management system (DBMS), many different types of database objects can exist. [1] [2] The following is a list of the most common types of database objects found in most relational databases (RDBMS):
The mixing and embedding of triggers and stored procedures was one of the breakthrough points up to support the use of PL/SQL in a OO paradigm. [6] The inclusion in the SQL syntax of statements such as [class].[object] , and the implementation of the object type [ 7 ] (like any OO language), completed the minimum requisites to a mapping ...
A database trigger is like a stored procedure that Oracle Database invokes automatically whenever a specified event occurs. It is a named PL/SQL unit that is stored in the database and can be invoked repeatedly. Unlike a stored procedure, you can enable and disable a trigger, but you cannot explicitly invoke it.
For example, instead of using commands such as insert, delete, and update to access a specific table in a database, a class and a few stored procedures could be created in the database. The procedures would be called from a method inside the class, which would return an object containing the requested values. Or, the insert, delete and update ...
An object database or object-oriented database is a database management system in which information is represented in the form of objects as used in object-oriented programming. Object databases are different from relational databases which are table-oriented.
SQL/JRT stored procedures are implemented in HSQLDB. [1] Java stored procedures have also been implemented in Oracle's JServer (or Aurora JVM), which was introduced in the Oracle Database version 8i in 1999; [2] [3] it is now called Oracle JVM. [4] IBM DB2 also supported Java stored procedures since about 1998, although using an external JVM ...
A database trigger is procedural code that is automatically executed in response to certain events on a particular table or view in a database. The trigger is mostly used for maintaining the integrity of the information on the database. For example, when a new record (representing a new worker) is added to the employees table, new records ...
