pl sql programs examples

The Oracle tutorial you are looking at is that Oracle uses Pl/sql to manipulate COM objects. The Pl/sql is extended by Oracle company to standard SQL, dedicated to programming in Oracle databases, and is a third-generation process programming language. Starting from Oracle8,

This is basically called "Modular design". A subroutine can be called by another subroutine or program that is called a calling program. Subroutines can be created:1. At the pattern level2.

(7) The user name and password of the current login, the result of the test and the reason are displayed after entering. After entering, click the Change Login button to modify the user name and password. The user name starts with the LC , the middle is the instance name (m572)in the GS Suite, and finally the 9999. The password is the password that is connected

Modular, decomposition of the program into a logical module; 2. reusability, which can be called by any number of programs; 3, maintainability, simplify maintenance operation; 4. Security: Mak

The current PL/SQL includes two parts, part of the database engine, and a separate engine that can be embedded in many products, such as the C language, the Java language, and so on. You can call these two parts: database PL/SQL and tool PL/SQL.The basic unit in

Label:  Pl-sql storage functions and stored procedures ORACLE provides the ability to store PL/SQL programs in a database and to execute them wherever they are. This is called a stored procedure or function.Procedures and functions are collectively referred to as

of an element in an array that matches the COUNTRY_ID key value, and if such an element exists in the array, the country_name is fetched from the array withoutTo perform a lookup query. If there is no such element, then a lookup query is performed and the results are stored as a new element in the array. You also need to understand that this technique is well suited for different statements with very few key values, in this case, the less the number of unique values in the country_id column, th
