The oracle database 11g has some new features such as PIVOT and UNPIVOT clauses,By using these clauses we can rotate the rows into column in output from a query.PIVOT and UNPIVOT are useful to see in large amount of data such as trends data over a period of time.Hera Ive shown a simple query to get the income details for three in year
Example:
Example:
SELECT *FROM (SELECT month,id,income FROM all_business WHERE year="2011" and id IN(1,2,3)) PIVOT (SUM(income) FOR month IN(1 AS JUNE,2 AS JULY,3 AS AUGUST)) ORDER BY id CREATE TABLE ALL_Income AS SELECT *FROM (SELECT month,id,income FROM all_business WHERE year="2011" and id IN(1,2,3)) PIVOT (SUM(income) FOR month IN(1 AS JUNE,2 AS JULY,3 AS AUGUST)) ORDERBY id SELECT *FROM ALL_Income UNPIVOT(income FOR month IN(JUNE,JULY,AUGUST))ORDER BY id
