使用 TOP 來限制插入的資料列
您可以使用 TOP 關鍵字來限制插入的資料列數。
下例會建立 NewEmployee 資料表,並在其中插入 Employee 資料表的前 10 位員工的地址資料。然後執行 SELECT 陳述式以驗證 NewEmployee 資料表的內容。
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
