sql sever怎么在视图里查询

要在 SQL Server 中创建一个视图，您可以使用CREATE VIEW语句。以下是一个示例：

CREATE VIEW [dbo].[vw_EmployeeDetails]
AS
SELECT 
    EmployeeID,
    FirstName,
    LastName,
    Gender,
    Email,
    Phone,
    AddressLine1,
    City,
    StateProvinceName,
    PostalCode,
    CountryRegionName,
    Title,
    HireDate,
    BirthDate
FROM 
    [HumanResources].[vEmployeeDepartmentHistory]
    INNER JOIN [Person].[Address] ON [HumanResources].[vEmployeeDepartmentHistory].[AddressID] = [Person].[Address].[AddressID]
    INNER JOIN [Person].[StateProvince] ON [Person].[Address].[StateProvinceID] = [Person].[StateProvince].[StateProvinceID]
    INNER JOIN [Person].[CountryRegion] ON [Person].[StateProvince].[CountryRegionCode] = [Person].[CountryRegion].[CountryRegionCode]
    INNER JOIN [HumanResources].[Employee] ON [HumanResources].[vEmployeeDepartmentHistory].[EmployeeID] = [HumanResources].[Employee].[EmployeeID]

在视图中查询数据与在表中查询数据相同。例如，如果你要查询上面的视图，你可以使用SELECT语句：

SELECT * FROM [dbo].[vw_EmployeeDetails]

这将返回视图中的所有列和行。
