sqlserver 通用存储过程分页代码(附使用ROW_NUMBER()和不使用ROW_NUMBER()两种情况性能分析)

CREATE TABLE [dbo].[Xtest](
[ID] [bigint] IDENTITY(1,1) NOT NULL,
[XName] [nvarchar](50) NULL,
[XDemo] [nvarchar](500) NULL,
CONSTRAINT [PK_xtest] PRIMARY KEY CLUSTERED
(
[ID] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY]

declare @i int
set @i=1
while(@i<500001)
begin
insert into dbo.Xtest(XName,XDemo) values(CAST(@i as varchar)+name+CAST(@i as varchar),这是第+CAST(@i as varchar)+的内容)
set @i=@i+1
end
