The following example shows how to use SQL Server Output with an insert statement:

Code
Description
CREATE TABLE Employee (Id INT PRIMARY KEY, Name VARCHAR(50), Salary FLOAT)

UPDATE Employee SET Salary = Salary + 1000
Update Employee Salary
OUTPUT INSERTED.Id, INSERTED.Name, INSERTED.Salary INTO @UpdatedData
Capture Updated Data into Temporary Table
