Multiple rows in a single row separated by comma

In Sql server Combining multiple rows into a single row, separated by commas, is a technique often referred to as "string aggregation" or "concatenation." In this process, data from different rows in a database or spreadsheet is merged into a single row, with each piece of information separated by a comma. This can be useful for creating summary reports, exporting data, or displaying multiple values in a more compact format. It's a method employed to simplify data representation, making it easier to work with and analyze, especially when dealing with large datasets or complex information.
