Can you explain the concept of Dynamic Pivot in SQL?

edit

The dynamic pivot in SQL is a technique in which an SQL query transforms data from rows to columns on the basis of a specified column. It is achieved by generating a dynamic SQL statement at runtime, as it cannot be predefined due to the changing nature of data.

The dynamic pivot query involves using the 'PIVOT' operator to transform data into the desired format, and 'UNPIVOT' to transform the data back to its original format.

The basic steps involved in creating a dynamic pivot query are:

1. Select the column which will act as the pivot column.
2. Use the 'PIVOT' operator to transform the data into the desired format.
3. Use dynamic SQL to generate the column names based on the data.
4. Execute the dynamic SQL query to get the output.

The dynamic pivot query is useful in situations where the table schema is unknown or the column list is subject to change. It provides a flexible and efficient way to display data in a tabular format.
