Limiting Inserted Rows by Using TOP

You can use the TOP keyword to limit the number of rows that are inserted.

The following example creates the NewEmployee table and inserts address data for the top 10 employees from the Employee table into it. The SELECT statement is then executed to verify the contents of the NewEmployee table.

USE AdventureWorks2008R2;
GO
IF OBJECT_ID (N'HumanResources.NewEmployee', N'U') IS NOT NULL
    DROP TABLE HumanResources.NewEmployee;
GO
CREATE TABLE HumanResources.NewEmployee
(
    BusinessEntityID int NOT NULL,
    LastName nvarchar(50) NOT NULL,
    FirstName nvarchar(50) NOT NULL,
    PhoneNumber Phone NULL,
    AddressLine1 nvarchar(60) NOT NULL,
    City nvarchar(30) NOT NULL,
    State nchar(3) NOT NULL, 
    PostalCode nvarchar(15) NOT NULL,
    CurrentFlag Flag
);
GO
-- Insert 10 random rows into the table NewEmployee.
INSERT TOP (10) INTO HumanResources.NewEmployee 
    SELECT
       e.BusinessEntityID, c.LastName, c.FirstName, pp.PhoneNumber,
       a.AddressLine1, a.City, sp.StateProvinceCode, 
       a.PostalCode, e.CurrentFlag
    FROM HumanResources.Employee e
        INNER JOIN Person.BusinessEntityAddress AS bea
        ON e.BusinessEntityID = bea.BusinessEntityID
        INNER JOIN Person.Address AS a
        ON bea.AddressID = a.AddressID
        INNER JOIN Person.PersonPhone AS pp
        ON e.BusinessEntityID = pp.BusinessEntityID
        INNER JOIN Person.StateProvince AS sp
        ON a.StateProvinceID = sp.StateProvinceID
        INNER JOIN Person.Person as c
        ON e.BusinessEntityID = c.BusinessEntityID;
GO
SELECT  BusinessEntityID, LastName, FirstName, PhoneNumber,
        AddressLine1, City, State, PostalCode, CurrentFlag
FROM HumanResources.NewEmployee;
GO
