One can use nested stored procedures by executing one stored procedure from within another. Stored procedures may return result sets, i.e., the results of a SELECT statement. Such result sets can be processed using cursors, by other stored procedures, by associating a result-set locator, or by applications. Stored procedures may also contain ...
A procedure may also be created in a PL/SQL package - this is called a Package Procedure. A procedure created in a PL/SQL anonymous block is called a nested procedure. The standalone or package procedures, stored in the database, are referred to as "stored procedures". Procedures can have three types of parameters: IN, OUT and IN OUT.
SQL/PSM (SQL/Persistent Stored Modules) is an ISO standard mainly defining an extension of SQL with a procedural language for use in stored procedures.Initially published in 1996 as an extension of SQL-92 (ISO/IEC 9075-4:1996, a version sometimes called PSM-96 or even SQL-92/PSM [2]), SQL/PSM was later incorporated into the multi-part SQL:1999 standard, and has been part 4 of that standard ...
6. Use Stored Procedures In the Database. Implementing stored procedures can add a layer of protection by isolating the database from direct user interaction, reducing the risk of certain ...
Often procedures can be used to greatly reduce the amount of information transferred within and outside of a system. For increased security, the system design may grant access to only the stored procedures and not directly to the tables. Fundamental stored procedures contain the logic needed to insert new and update existing data.
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 ...
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.
