Limitando a inserção de linhas usando TOP

Você pode usar a palavra-chave TOP para limitar o número de linhas que são inseridas.

O exemplo a seguir cria a tabela NewEmployee e insere nela os dados de endereço dos 10 funcionsários no alto da tabela Employee. Depois, a instrução SELECT é executada para verificar os conteúdos da tabela NewEmployee.

USE AdventureWorks;
GO
IF OBJECT_ID (N'HumanResources.NewEmployee', N'U') IS NOT NULL
    DROP TABLE HumanResources.NewEmployee;
GO
CREATE TABLE HumanResources.NewEmployee
(
    EmployeeID int NOT NULL,
    LastName nvarchar(50) NOT NULL,
    FirstName nvarchar(50) NOT NULL,
    Phone 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 TOP (10) INTO HumanResources.NewEmployee 
    SELECT
       e.EmployeeID, c.LastName, c.FirstName, c.Phone,
       a.AddressLine1, a.City, sp.StateProvinceCode, 
       a.PostalCode, e.CurrentFlag
    FROM HumanResources.Employee e
        INNER JOIN HumanResources.EmployeeAddress AS ea
        ON e.EmployeeID = ea.EmployeeID
        INNER JOIN Person.Address AS a
        ON ea.AddressID = a.AddressID
        INNER JOIN Person.StateProvince AS sp
        ON a.StateProvinceID = sp.StateProvinceID
        INNER JOIN Person.Contact as c
        ON e.ContactID = c.ContactID;
GO
SELECT  EmployeeID, LastName, FirstName, Phone,
        AddressLine1, City, State, PostalCode, CurrentFlag
FROM HumanResources.NewEmployee;
GO
