SQL and T-SQL are two different methods of querying a database. There are many resemblances between the two, but significant differences make them each unique. If you’re new to SQL or SSIS (and if you’re reading this article, you likely are), this guide will help clarify the differences between these essential data technologies.

What are the differences between T-SQL and SSIS?

What is Standard SQL?

Standard SQL is a subset of ANSI SQL. It is the most typical and widely used version of SQL, as it is used in most database management systems (DBMS). Standard SQL uses a set of rules defined by the American National Standards Institute (ANSI), which defines standards for many different types of technologies, including computer programming languages.

Standard SQL was first published in 1986 as part of ANSI X3H2, or “Database Language – SQL.” This document included six parts: Data Definition Language (DDL), Data Manipulation Language (DML), Integrity Constraints and Privileges, Transaction Management Features, Data Types, and Schemas; Extension Statements; Application Programming Interface (API) Reference Manuals; Internationalization Considerations

What is T-SQL?

T-SQL is a programming language used to manipulate data in SQL databases. It is the primary language used to work with SQL Server, a Structured Query Language (SQL) dialect.

T-SQL enables you to create, modify and delete tables; insert new records into existing tables; update existing records in a table; and delete records from one or more tables.

What is the difference between SQL and T-SQL?

  • SQL is a standard language for databases.
  • T-SQL is a dialect of SQL that is specific to Microsoft SQL Server. It queries, manipulates, and administers data in Microsoft SQL Server databases.
  • SSIS (SQL Server Integration Services) is a tool for data integration with other systems, such as Excel or Access databases, by extracting data from one system and importing it into another system (or multiple systems).

Which is better to learn?

If you want to do data analysis, T-SQL is the better choice. It’s a good language for writing queries and creating stored procedures.

If you want to automate data transformation, SSIS is the better choice. It’s much more powerful than T-SQL in this area because it allows you to build complex ETL processes using drag-and-drop tools, making it easy for anyone with no programming experience (including nontechnical business users) to create these workflows without having any knowledge of SQL or T-SQL.


T-SQL and SQL are different languages to query data from a database. T-SQL is a more advanced version of SQL with many more features than standard SQL.
