What is PL/SQL?

Procedural Language/structured question language (PL/SQL) is Oracle’s Implementation of a established Query Language (SQL) Programming Language Extension. PL/SQL is a effective tool that combines SQL’s Querying ability with the added bonus of Programming Functions.

What Does Procedural Language/Structured Query Language Mean?

Beginning with Oracle7 in the early Nineties, Oracle first advanced and presented PL/SQL. Since that time, PL/SQL has been blanketed anyplace SQL is offered. A separate Oracle PL/SQL Engine inside the Software Program is used to technique the PL/SQL Code.

Like SQL, PL/SQL follows a strict Syntax-conTrolling shape. The PL/SQL code Block consists of 3 principal sections:

Declaration (non-compulsory): Declaration segment creation key-word is DECLARE. Execution (mandatory): Main execution section creation Keyword is BEGIN. Exception (elective): Exception dealing with phase advent keyword is EXCEPTION. Thus, the Format look is established as follows:

DECLARE declaration_section BEGIN Program_execution EXCEPTION Exception_handling

Objects created handiest via the use of PL/SQL, instead of in basic terms SQL, encompass capabilities, programs and processes. However, most applications that run SQL code also support PL/SQL. Thus, Database directors and Builders not often separate SQL and PL/SQL code.
