PL/SQL First Program - Shikshaglobe

PL/SQL is a procedural language that has been developed by Oracle Corporation. It is a combination of SQL along with the procedural features of programming languages. It is one of the three main languages used in the Oracle Database, alongside SQL and Java.PL/SQL First ProgramWhen you are ready to write your first PL/SQL program, you will need to use a text editor to create a new file. The file should have a .sql extension and can be saved anywhere on your computer. Once you have saved the file, you can open it in any text editor and begin writing your code.Your first PL/SQL program should start with a DECLARE statement. This statement is used to declare any variables that will be used in the program. Following the DECLARE statement, you should write your executable code. This code will be executed when the program is run. Finally, you should end your program with an END statement.Once you have writtenPL/SQL is a procedural extension of SQL that adds control structures, looping, and other programming constructs to the database language. A PL/SQL program consists of blocks, which can be nested within each other. The outermost block is the main or outer block, and is required for all programs. Inner blocks are not required, but they can be useful for modularizing your code. Each block has a header, a declarative part, an executable part, and an exception-handling part. The header begins with the keyword DECLARE (or IS in some cases) and ends with the keyword BEGIN. The declarative part is optional and is used to declare variables and constants. The executable part is required and contains the actual PL/SQL code that will be executed. Finally, the exception-handling part is also optional and is used to handle errors that might occur during execution of the codePL/SQL is a procedural language extension to SQL. It has a syntax similar to that of Ada or Pascal. The name PL/SQL stands for Procedural Language/Structured Query Language.PL/SQL is Oracle's proprietary procedural language extension to SQL. PL/SQL adds procedural constructs like conditionals and loops to the declarative SQL, making it a fully featured programming language.PL/SQL programs are compiled into bytecode which can be stored in the database and executed as needed. PL/SQL is a portable, high-performance, strongly typed, object-oriented language that can be used in a wide variety of programming environments.PL/SQL is a procedural language extension to SQL. It has syntax and semantics similar to other structured programming languages. In PL/SQL, program units are compiled into a library or executable which is then stored in the database. A program unit is a collection of code which can be stored as a named object in the database. The two most common program units are procedures and functionsProcedures are blocks of code which can take input parameters, process them and return an output value. Functions are similar to procedures but they must return a value back to the caller. In addition, there are anonymous blocks which are unnamed pieces of code which cannot be stored in the database and can only be executed on an ad-hoc basis.
