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:.

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. FOR column4 IN value1, value2, … : This defines the list of unique values from column4 that will be used to create the new columns in the output.
