通用SQL存儲過程分頁以及asp.net后臺調(diào)用的方法

創(chuàng)建表格并添加300萬數(shù)據(jù)

use Stored
CREATE TABLE UserInfo( --創(chuàng)建表
id int IDENTITY(1,1) PRIMARY KEY not null,--添加主鍵和標識列
UserName varchar(50) 
)
 
declare @i int --添加3百萬數(shù)據(jù)，大概4分鐘時間
set @i=1
while @i3000000
begin
insert into UserInfo (UserName) values(@i)
set @i=@i+1
end

存儲過程T-SQL

create PROCEDURE [dbo].[GetDataList]
(
 @TableName varchar(5000),    --表名
 @Fields varchar(5000) = '*',   --字段名(全部字段為*)
 @OrderField varchar(5000),    --排序字段(必須!支持多字段)
 @OrderType varchar(5000),    --排序類型
 @sqlWhere varchar(5000) = Null, --條件語句(不用加where)
 @pageSize int,          --每頁多少條記錄
 @pageIndex int = 1 ,       --指定當前為第幾頁
 @TotalPage int output,      --返回總頁數(shù) 
 @totalRecord int output    --計算總記錄數(shù)       --返回總記錄數(shù)
 )
as
begin  Begin Tran --開始事務  
  
  Declare  @sql nvarchar(500); 
  if (@SqlWhere='' or @sqlWhere=NULL)
    set @sql = 'select @totalRecord = count(*) from ' + @TableName
  else
    set @sql = 'select @totalRecord = count(*) from ' + @TableName + ' where ' + @sqlWhere  
      EXEC sp_executesql @sql,N'@totalRecord int OUTPUT',@totalRecord OUTPUT--計算總記錄數(shù) 
        
  
  --計算總頁數(shù)

    set @sql = 'Select * FROM (select ROW_NUMBER() Over(order by ' + @OrderField +' ' + @Ordertype+' ) as rowId,' + @Fields + ' from ' + @TableName
