How Can I Inspect Table Variable Values During T-SQL Debugging?

Inspecting Table Variable Values During Debug Time in T-SQL

Many developers face challenges in visualizing the contents of table variables during debugging in SQL Server Management Studio (SSMS). Fortunately, there is a method to display these values, allowing for easier troubleshooting and analysis.

To view the data stored in a table variable, utilize the following code snippet:

DECLARE @v XML = (SELECT * FROM <tablename> FOR XML AUTO)

Place this statement at the point in your code where you want to inspect the table's contents. The output, though represented in XML format, will display within the locals window as a table, providing a clear representation of the rows and cells.

You can further enhance the debugging process by adding @v to the watch window. This creates a dynamic display that updates whenever the table variable's values change, offering continuous visibility throughout your debugging session.
