Difference between SQL and T-SQL

Difference between SQL and T-SQL

SQL and T-SQL are both database query languages that allow you to access, manipulate, and store data. However, there are some key differences between the two. In this blog post, we will take a look at those differences and explore why you might want to use one over the other. Stay tuned!

What is SQL?

SQL is a standard database query language that is used for accessing and manipulating data in relational databases. SQL commands are divided into four main categories: Data Manipulation Language (DML), Data Definition Language (DDL), Data Control Language (DCL), and Transaction Control Statements (TCS). SQL can be used to retrieve data from a database, insert new data into a database, update existing data in a database, or delete data from a database.

SQL can also be used to create and drop database objects such as tables, indexes, and views. SQL is a powerful tool that can be used to perform complex queries on large databases. However, SQL can also be used to write simple queries on small databases. SQL is a versatile language that can be used in many different ways.

What is T-SQL?

T-SQL is a Microsoft SQL Server database programming language that adds extensions to the standard SQL commands, making it more powerful and flexible. T-SQL is used to write stored procedures, insert or update data, and query databases. T-SQL can also be used to create user-defined functions, views, and triggers. T-SQL is an important tool for database administrators and developers who work with Microsoft SQL Server. T-SQL is not only used on Microsoft SQL Server but it can also be used on other relational database management systems that support the SQL language. T-SQL is a valuable skill for anyone who works with databases.

Difference between SQL and T-SQL

SQL and T-SQL are both programming languages that are used to manage data in a database. SQL is the standard language for relational database management systems, while T-SQL is a proprietary extension of SQL that is used by Microsoft SQL Server. Both SQL and T-SQL can be used to write stored procedures, create database objects, and query data.

However, T-SQL includes additional features such as support for temporary variables and error handling. In addition, T-SQL is designed specifically for use with Microsoft SQL Server, while SQL can be used with any type of relational database management system. As a result, T-SQL is not portable across different database platforms.


In this blog post, we have looked at the key differences between SQL and T-SQL. We’ve seen that while they share some similarities, there are also some important distinctions. Hopefully, this information will help you make an informed decision about which language to use for your database development needs.
