PL/SQL is a procedural language designed particularly to embrace SQL statements inside its syntax. PL/SQL program models are compiled by the Oracle Database server and saved contained in the database. And at run-time, each PL/SQL and SQL run inside a similar server course, bringing optimum effectivity. PL/SQL mechanically inherits the robustness, safety, and portability of the Oracle Database.

The PL/SQL programming language was developed by Oracle Corporation in the late 1980s as a procedural extension language for SQL and the Oracle relational database. Following are sure notable info about PL/SQL −

  • PL/SQL is a very moveable, high-performance transaction-processing language.
  • PL/SQL offers a built-in, interpreted, and OS-independent programming setting.
  • PL/SQL may immediately be known as from the command-line SQL*Plus interface.
  • The direct name will also be constituted of exterior programming language calls to databases.
  • PL/SQL’s basic syntax is predicated on that of ADA and Pascal programming language.
  • Other than Oracle, PL/SQL is offered in TimesTen in-memory database and IBM DB2.

 

Features of PL/SQL

PL/SQL has the next options −

  • PL/SQL is tightly built-in with SQL.
  • It affords intensive error checking.
  • It affords quite a few data types.
  • It affords a range of programming constructions.
  • It helps structured programming by features and procedures.
  • It helps object-oriented programming.
  • It helps the event of internet functions and server pages.

 

Advantages of PL/SQL

PL/SQL has the next benefits −

  • SQL is the usual database language and PL/SQL is strongly built-in with SQL. PL/SQL helps each static and dynamic SQL. Static SQL supports DML operations and transaction management from PL/SQL block. In Dynamic SQL, SQL allows embedding DDL statements in PL/SQL blocks.
  • >PL/SQL permits sending a whole block of statements to the database at one time. This reduces community site visitors and offers excessive efficiency for the functions.
  • PL/SQL provides excessive productiveness to programmers as it could possibly question, remodel, and replace data in a database.
  • PL/SQL saves time on design and debugging by strong features, equivalent to exception dealing with, encapsulation, information hiding, and object-oriented information varieties.
  • Functions written in PL/SQL are absolutely moveable.
  • PL/SQL offers high-security stage.
  • PL/SQL offers entry to predefined SQL packages.
  • PL/SQL offers assist for Object-Oriented Programming.
  • PL/SQL offers assist for growing Net Functions and Server Pages.
