Hi, PIVOT rotates a table-valued expression by turning the unique values from one column in the expression into multiple columns in the output, and performs aggregations where they are required on any remaining column values that are wanted in the final output. UNPIVOT performs the opposite operation to PIVOT by rotating columns of a table-valued expression into column values.

PIVOT in SQL Server allows you to write a cross-tabulation. This means that you can aggregate your results and rotate rows into columns.
