Understanding SQL Server Line Numbers

Hello Dev, are you struggling with understanding SQL Server line numbers? It’s not uncommon for developers to encounter issues with line numbers in SQL Server. In this article, we will explore everything about SQL Server line numbers and how to work with them in your query.

What are SQL Server Line Numbers?

Before we dive into the details, let’s start with the basics. SQL Server line numbers are the line numbers that are displayed in the query editor of SQL Server Management Studio (SSMS). These line numbers help you in identifying the line on which the error occurred while running the query.

Line numbers are not part of the SQL language and hence, they are not saved in the database. They are simply an aid to the developer and are only visible in the SSMS query editor.
