What is Unpivoting?
Unpivoting is a data transformation process that involves turning columns of data into rows. In other words, it involves reorganizing a dataset so that each observation is represented as a single row, rather than multiple columns.
Unpivoting is often used in data analysis and business intelligence to make it easier to work with data in certain scenarios. For example, if you have a dataset where each column represents a different month of data, you may want to unpivot the data so that each row represents a single month. This can make it easier to calculate trends and perform other types of analysis.
In SQL, unpivoting can be achieved using the UNPIVOT operator. In other data analysis tools such as Excel, unpivoting can be achieved using the “Unpivot” function or by using the Power Query feature.
- Unpivot Other Columns: This trick allows you to quickly unpivot multiple columns of data in a single step. To do this, you'll need to select the columns you want to unpivot, right click, and select Unpivot Other Columns. This will convert the data into a single column, while keeping all of the data in the same row.
- Unpivot All Columns: This trick allows you to quickly unpivot all columns in a table in a single step. To do this, you'll need to select the table, right click, and select Unpivot All Columns. This will convert the data into a single column, while keeping all of the data in the same row.
