❶ SQL如何實現數據分頁,要具體語句,謝謝
可以的，用存儲過程
分頁存儲過程如下
CREATE PROCEDURE GetRecordFromPage
@tblName varchar(255), -- 表名
@RetColumns varchar(1000) = '*', -- 需要返回的列，默認為全部
@Orderfld varchar(255), -- 排序欄位名
@PageSize int = 10, -- 頁尺寸
@PageIndex int = 1, -- 頁碼
@IsCount bit = 0, -- 返回記錄總數, 非 0 值則返回
@OrderType varchar(50) = 'asc', -- 設置排序類型, 非 asc 值則降序
@strWhere varchar(1000) = '' -- 查詢條件 (注意: 不要加 where)
AS
declare @strSQL varchar(1000) -- 主語句
declare @strTmp varchar(300) -- 臨時變數
declare @strOrder varchar(400) -- 排序類型
if @IsCount != 0 --執行總數統計
begin
if @strWhere != ''
set @strSQL = "select count(*) as Total from [" + @tblName + "] where " + @strWhere
else
set @strSQL = "select count(*) as Total from [" + @tblName + "]"
end
else --執行查詢操作
begin
if @OrderType != 'asc'
begin
set @strTmp = "<(select min"
set @strOrder = " order by [" + @Orderfld +"] desc"
end
else
begin
set @strTmp = ">(select max"
set @strOrder = " order by [" + @Orderfld +"] asc"
end
set @strSQL = "select top " + str(@PageSize) + " " + @RetColumns + " from ["
+ @tblName + "] where [" + @Orderfld + "]" + @strTmp + "(["
+ @Orderfld + "]) from (select top " + str((@PageIndex-1)*@PageSize) + " ["
+ @Orderfld + "] from [" + @tblName + "]" + @strOrder + ") as tblTmp)"
+ @strOrder
if @strWhere != ''
set @strSQL = "select top " + str(@PageSize) + " " + @RetColumns + " from ["
+ @tblName + "] where [" + @Orderfld + "]" + @strTmp + "(["
+ @Orderfld + "]) from (select top " + str((@PageIndex-1)*@PageSize) + " ["
+ @Orderfld + "] from [" + @tblName + "] where (" + @strWhere + ") "
+ @strOrder + ") as tblTmp) and (" + @strWhere + ") " + @strOrder
if @PageIndex = 1
begin
set @strTmp = ""
if @strWhere != ''
set @strTmp = " where (" + @strWhere + ")"
set @strSQL = "select top " + str(@PageSize) + " " + @RetColumns + " from ["
+ @tblName + "]" + @strTmp + " " + @strOrder
end
end
exec (@strSQL)
