What Is PL/SQL?
PL/SQL (also known as procedural language extension to the Structured Query Language) is primarily a block-structured, procedural language. In the early 1990s, it was developed by Oracle Corporation. Oracle uses PL/SQL besides the other two languages, SQL and Java. Being an extension of SQL, it embeds the SQL queries in its syntax. PL/SQL also provides several iteration constructs to the SQL to overcome some constraints of SQL Language. It provides a holistic programming language solution for developing crucial applications on Oracle Databases.
It is a well-structured and easily comprehensible language. Its construct is sufficient to express the intention in the code clearly. Besides, PL/SQL is one of the easiest languages to learn. The language is aimed at combining procedural programming language and database language.
PL/SQL is a portable language for Oracle Database development. It’s easy to run PL/SQL apps on any OS and platform where Oracle Database has been deployed. Being an embedded language, it is only executable in an Oracle Database. It was not intended to be used as a standalone language. PL/SQL is a highly productive database language that lets you develop procedural/modular programs in Oracle Database.
