      <p>Unpivot is used to normalize tables that are built for cross tabular reporting purposes. The unpivot operator rotates the column values for all the pivoted columns. A variable column, value column and all columns from the source table except the unpivot columns are projected into the result table. The variable column and value columns in the result table indicate the pivoted column name and values respectively.</p>
      <p>The response is returned as a dynamic schema. For details see: <a href="/content/api/concepts/#dynamic-schemas" target="_top">dynamic schemas documentation</a>. </p>
