SQL Vs PL/SQL | Difference between SQL and PL/SQL

SQL and PL/SQL are relational database languages. SQL is a structured query language that inserts, deletes alters or manipulates data in a database. PL/SQL is a procedural language that is an extension of SQL, and it has SQL statements inside its syntax. Let us discuss some more Differences between SQL and PL/SQL with the help of the comparison given below. 

What is SQL?

Data scientists may manage access information from databases using the computer language known as structured quarry language (SQL). Tables, columns, and rows are used to organize and connect data amongst relational databases, which are utilized by many industries to store data, in addition to developing their own databases. SQL is the most widely used technology for creating and maintaining these databases. Furthermore, data scientists use SQL to do data analysis, generate quick data insights, and extract information from large databases. Databases may be used to power websites, applications, and corporate software tools.

What is PL/SQL?

Oracle was founded in 1992 as a programming language based on SQL (PL/SQL), a procedural database language. The capacity of the PL/SQL programming language to handle large faults is widely recognized. It also boasts a lightning-fast processing speed. As a result, it may easily execute several statements at the same time in the form of code blocks. Packages, triggers, functions, and other components that increase the overall usefulness of any particular activity are examples of these. The full form of PL/SQL is SQL procedural language extensions. Its grammar is based on the Pascal and ADA programming languages.

SQL Vs PL/SQL | Difference between SQL and PL/SQL:

  • SQL is a database-structured query language. while PL/SQL is a database programming language using SQL.
  • Variable is not available in SQL. Variable, constraints, and data types features are available in PL/SQL.
  • SQL no supported control structures like for loop, if any other. While PL/SQL is controlled structures are available like for loop, while loop, if any other.
  • SQL is a data-oriented language. While PLSQL is an application-oriented language.
  • Query performs the single operation in SQL. PL/SQL block performs a group of operations as a single block resulting in reduced network traffic.
  • SQL is a declarative language. PL/SQL is a procedure language.
  • SQL can be embedded in PL/SQL. PL/SQL can't be embedded in SQL.
  • SQL directly interacts with the database server. While  PL/SQL does not interact directly with the database server.
  • SQL does not provide error and exception handling. PL/SQL provides error and exception handling.
  • SQL has used write queries DDL and DML. The code block, functions, procedures triggers, and packages can be written using PL/SQL.
  • SQL does not have a fast processing speed for large amounts of data. PL/SQL, on the other hand, has a fast processing speed for large amounts of data.
  • SQL can be used to retrieve, add, remove, or change data in a database. You may use PL/SQL to create apps that display SQL data in a logical manner.
