在SQL Server 2008中做PIVOT表

Question

Seems like it should be really easy to change this one row data:

SalesTotal Refunds  Discount Taxes  
63093.05   -102.52  3905.11  2523.32

Into this:

SalesTotal  63093.05
Refunds      -102.52
Discount     3905.11
Taxes        2523.32

Using the PIVOT in SQL. But... in all the examples I found;

http://www.izenda.com/Site/KB/FAQ/How-do-I-create-a-pivot-table-in-Microsoft-SQL- http://blog.sqlauthority.com/2008/05/22/sql-server-pivot-table-example/ http://www.mssqltips.com/sqlservertip/1019/crosstab-queries-using-pivot-in-sql-server/ http://msdn.microsoft.com/en-us/library/ms177410(SQL.105).aspx Etc....

there was the need of doing addition aggregates in the PIVOT command.
All I am wanting to do is turn the table on its side.

Any way of doing that?

Answer 1

You should be looking for UNPIVOT instead. Here is a way of getting the results you want with CROSS APPLY (this assumes that all of your columns have a compatible data type):

SELECT  x.Col,
        x.Value
FROM YourTable t
CROSS APPLY 
(
    VALUES
        ('SalesTotal', t.SalesTotal),
        ('Refunds', t.Refunds),
        ('Discount', t.Discount),
        ('Taxes', t.Taxes)
) x(Col, Value);

Answer 2

You need UNPIVOT not PIVOT to rotate columns into rows

SELECT Type, value from
(SELECT * from Table1) T
UNPIVOT
( value for Type in ( [SalesTotal], [Refunds], [Discount], [Taxes])
) unpvt
