Meaning, in the above source table, if we have sales amount only, or profit amount only, we can use pivot. It needs to be pivoted for type1 and type2 too. When we run the above pivot statement SQL Server gives these 4 errors:.

The following diagram illustrates what PIVOT can do where we take 4 rows of data and turn this into 1 row with 4 columns. For a certain report, the desired output is actually as follows apologies for the messy arrows :. Another scenario is when we want to export data and we need it in a different format and table structure. Most of the scenarios to swap rows to columns is to deliver a report with a specific format. The data analyst or someone in the company requires the information in a different way than the table structure. If it is a one-time requirement, a query can help. Otherwise, a view could be used.

Well, as a developer or analyst who has to wrestle with loads of data, SQL Pivot could soon become your new best friend. SQL Pivot is a relational operator that transforms data from row level to column level. The magic of SQL Pivot lies in its ability to rotate a table-valued expression, turning unique values from one specified column into multiple columns in the output and performing aggregations where they are required. SQL Pivot is a powerful tool used in SQL Server to rotate table-valued expressions and convert rows into columns and perform aggregations on specific columns. The PIVOT relational operator turns the unique row values in one column into multiple pivot columns in the output. This operation is also known as a cross-tabulation. The list of values provided in the IN clause should be exhaustive and static. In the above example, the query will return a result set where each product has a separate row, and the sales for each year are shown in separate columns. Suppose we have a Scores table that stores the scores of students in different subjects:. This SQL query will provide a summary of the scores each student has achieved in the subjects Math and English. In this row, there will be two columns for math and English. The values in these columns will be the total scores summed up if there are multiple entries the respective student achieved in these subjects. In SQL Server, a pivot table is a feature or concept that allows you to change the data from being displayed in rows to columns. A pivot table is essentially a piece of summarized information that is generated from a large underlying dataset. This helps in data analysis, especially when you need to convert columns into rows for easier interpretation and presentation.

Pivoting in SQL can become increasingly complex with advanced techniques, but mastering these concepts will enable you to create more sophisticated reports, manipulate data, and perform data transformations like dynamically converting rows to columns with ease.

SQL PIVOT is a powerful operation that allows you to transform rows of data into columns, providing a more structured and readable format for reporting and analysis. The PIVOT operator takes a table-valued expression as input and rotates it by turning the unique values in one column into multiple columns in the output. This transformation typically involves aggregating the values in another column based on the pivoted dimensions.
