The data below are a subset of the Resale dataset provided with the software. This (computer simulated) data. gives the selling price, the number of bedrooms, the total square footage (finished and unfinished), and the size of. the lots for 150 residential properties sold during the last four months in two states.
A common scenario where PIVOT can be useful is when you want to generate cross-tabulation reports to summarize data. For example, suppose you want to query the PurchaseOrderHeader table in the AdventureWorks2008R2 sample database to determine the number of purchase orders placed by certain employees.
If the data source for your pivot table is an external database table created with a separate database management program, such as Access, you need to click the Use an External Data Source button, click the Choose Connection button, and then click the name of the connection in the Existing Connections dialog box.
