Transact-SQL Reference (Database Engine)
Applies to: SQL Server (all supported versions) Azure SQL Database Azure SQL Managed Instance Azure Synapse Analytics Analytics Platform System (PDW)
This topic gives the basics about how to find and use the Microsoft Transact-SQL (T-SQL) reference topics. T-SQL is central to using Microsoft SQL products and services. All tools and applications that communicate with a SQL database do so by sending T-SQL commands.
T-SQL compliance with SQL Standard
For detailed technical documents about how certain standards are implemented in SQL Server, see the Microsoft SQL Server Standards Support documentation.
Tools that use T-SQL
Some of the Microsoft tools that issue T-SQL commands are:
Locate the Transact-SQL reference topics
To find T-SQL topics, use search at the top right of this page, or use the table of contents on the left side of the page. You can also type a T-SQL key word in the Management Studio Query Editor window, and press F1.
Find system views
To find the system tables, views, functions, and procedures, see these links, which are in the Using relational databases section of the SQL documentation.
- System catalog Views
- System compatibility views
- System dynamic management views
- System functions
- System information schema views
- System stored procedures
- System tables
"Applies to" references
The T-SQL reference topics encompass multiple versions of SQL Server, starting with 2008, and the other Azure SQL services. Near the top of each topic is a section that indicates which products and services support subject of the topic.
For example, this topic applies to all versions, and has the following label.
APPLIES TO: SQL Server Azure SQL Database Azure Synapse Analytics Parallel Data Warehouse
Another example, the following label indicates a topic that applies only to Azure Synapse Analytics and Parallel Data Warehouse.
Applies to: Azure Synapse Analytics Analytics Platform System (PDW)
In some cases, the topic is used by a product or service, but all of the arguments are not supported. In this case, other Applies to sections are inserted into the appropriate argument descriptions in the body of the topic.
