字段组合查询

刚有网友问及，数据表的姓与名是分开存储，但查询时，传入的是全名，怎样实现查询。

Insus.NET简单写了一个例子，可以参考之：

IF OBJECT_ID('[dbo].[Employee]') IS NOT NULL
    DROP TABLE [dbo].[Employee]

CREATE TABLE [dbo].[Employee]
(
    [FirstName] NVARCHAR(40),
    [LastName] NVARCHAR(40)
)
GO
INSERT INTO [dbo].[Employee] ([FirstName],[LastName]) VALUES (N'张',N'三'),(N'李',N'四'),(N'黄',N'五')


SELECT [FirstName],[LastName] FROM [dbo].[Employee] WHERE ([FirstName] + [LastName]) = N'李四'
