Learning on demand databases can play the key role for any one who aspire to get into IT jobs. It is easy to learn, adapt, grow your career significantly at multiple levels. Giving you the quick difference between SQL Vs PL SQL as this will help you understand the pros and cons of it in detail.
About SQL
SQL is the structured query language employes in managing the database efficiently via commands. DML and DDL are the two critical commands in SQL that cover different operations to derive the targeted outputs for the users.
About PL SQL
PLSQL is the extended version of SQL developed by Oracle. It is procedural function to display the results executed by SQL. In short, it is the extension of SQL and supports the execution of multiple procedures, triggers, and functions. The excellent data recovery function has examine one of the most sought-after tools in the industry.
The act of retrieving data from a Database Management System (DBMS), such as ODBMS, is known as Data Retrieval. Since there is no uncertainty in the data, it is assumed that it is structured in this instance. The user enters a set of requirements by way of a query in order to obtain the needed data.

Let us look into the key differences between both languages for better visibility of their pros and cons.
Difference Between SQL And PLSQL
| S.No | Comparison Point | SQL | PLSQL |
| 1 | Definition | It is a Structured Query language for fetching information using queries. | It is a procedural language used to handle the queries executed by SQL in an enhanced manner. |
| 2. | Commands | DDL and DML are the two major commands covered under SQL. Queries are written using DDL commands like create, alter, drop, and truncate. The DML commands for queries include select, update, and delete. | PLSQL is known for queries and covers more orders and primary functions. |
| 3. | Execution and Operation | SQL is capable of executing a single query only at a time. | PLSQL is skilful in running multiple operations at once. This in turn tends to reduce the network traffic of the website. |
| 4. | Speed | The speed of SQL is relatively slow while fetching bulk data. | The processing speed of PLSQL is brilliant with heavy data. |
| 5. | Objective | SQL aims at writing queries for fetching information from the database. | The goal of PLSQL is to run triggers, packages, and big blocks of code. |
| 6. | Appending | SQL statements can be appended within PLSQL declarations. | PLSQL Codes cannot be inserted among the SQL code. |
| 7. | Usage | SQL is adapted in companies that involve bulk data for saving and retrieving customer data. It is also the best back-end tool for storing website data. The main application is on web servers and works as a great integration tool with PHP. SQL is useful in generating reports based on the statistical information present on any website. | PLSQL executes logical statements in collaboration with PHP and JAVA languages. It extends support for web apps and server pages. |
