How to Describe Table in SQL Server – A Guide for Devs

Hello Devs, if you’re working with SQL Server, you need to know how to describe a table. In this article, we’ll cover the basics of describing a table in SQL Server. Whether you’re new to SQL or an experienced developer, this guide will help you understand the importance of describing tables and how to do it properly.

What is Describing a Table in SQL Server?

Describing a table in SQL Server means retrieving information about a table’s structure and properties. This information includes the table’s columns, data types, constraints, indexes, and more. It’s essential to describe a table before you start working with it because it helps you understand how the table is organized and what data it contains.

Describing a table is also useful when you need to modify the table or create a new table based on the existing one. By knowing the table’s structure and properties, you can make informed decisions about how to change it or use it as a template for a new table.

How to Describe a Table in SQL Server

Using the SQL Server Management Studio

The easiest way to describe a table in SQL Server is to use the SQL Server Management Studio (SSMS). Here’s how:

1. Open SSMS.
2. Connect to the SQL Server instance where the table is located.
3. Expand the Databases node and select the database that contains the table.
4. Expand the Tables node and select the table you want to describe.
5. Right-click the table and select Script Table as > CREATE To > New Query Editor Window.

This will generate a SQL script that creates the table. You can see the table’s structure and properties in the script.

Using the Transact-SQL Query Language

If you prefer to use the Transact-SQL (T-SQL) query language, you can describe a table using the sp_help system stored procedure. Here’s an example:

USE MyDatabase;EXEC sp_help 'MyTable';

This will display the same information as the SSMS method in a result set.
