How to Add a Line Break in a SQL Server Stored Procedure

When writing SQL Server stored procedures, developers often encounter the need to format output strings to improve readability. One common requirement is to insert a line break within a string—especially when concatenating multiple lines of text. In this guide, we will explore how to achieve that effectively, ensuring your stored procedure outputs are clear and structured.

Understanding the Challenge

Imagine you are creating a stored procedure that needs to compile a lengthy message from various records. Without the ability to insert line breaks, the output will appear as one long, unbroken string, making it difficult for users to read and understand. Here’s a brief example of what it might look like:

In this scenario, you want to include a line break after certain parts of your output, but how do you do that in SQL Server?

Adding a Line Break in SQL Server

To effectively add a line break in your stored procedure, you will need to utilize the CHAR function in SQL Server. The CHAR function is used to return the character for a specified ASCII code. For line breaks, you will primarily be using two ASCII values:

CHAR(13): This represents the carriage return (CR).

CHAR(10): This represents the line feed (LF).

When combined, these characters create a new line in your string.

Step-by-Step Solution

Declare a Variable for Line Break: First, you'll need to declare a variable to store your line break sequence.

Conclusion

Adding a line break in a SQL Server stored procedure allows you to format output strings for better readability, making it easier for users to understand the information presented. By using the CHAR function with the appropriate ASCII codes, you can insert line breaks seamlessly into any concatenated string operations within your SQL procedures.

Now, you can confidently craft formatted, multi-line messages in your SQL Server stored procedures that enhance the overall user experience!
