执行代码如下:
-- Test Employees Table on Northwind database
EXEC spGetPageOfRecords 5, 2, 'EmployeeID, LastName, FirstName, Title, City, Region, Country', 'Employees', '', 'EmployeeID', 0, 'EmployeeID'
-- Test Customers Table on Northwind database
EXEC spGetPageOfRecords 10, 6, 'CustomerID, CompanyName, ContactName, ContactTitle, Address, City, Region, Country', 'Customers', '', 'CustomerID', 0, 'CustomerID'
