SQL stands for Structured Query Language. It is a database query language used to execute a command or a single query at a time. It is a source of data that needs to be displayed. You can write commands as well as queries using Data Manipulation language (DML) and Data Definition Language (DDL) statements. You can use SQL to add, modify, retrieve, manipulate, or delete data from the database. SQL statements can be embedded in PL/SQL.
PL/SQL, on the other hand, is a procedural language extension to SQL. It is used to execute a single block of code at once. It creates an application that helps to display SQL’s acquired data. You can use PL/SQL to write a block of code with functions, procedures, variables, and packages. Also, you can use PL/SQL to create server pages or applications that can display the data from SQL in a comprehensive format. PL/SQL statements cannot be embedded in SQL.
