復制代碼 代碼如下:

CREATE PROCEDURE pagination
@tblName varchar(255), -- 表名
@strGetFields varchar(1000) = '*', -- 需要返回的列
@fldName varchar(255)='', -- 排序的字段名
@PageSize int = 10, -- 頁尺寸
@PageIndex int = 1, -- 頁碼
@doCount bit = 0, -- 返回記錄總數, 非 0 值則返回
@OrderType bit = 0, -- 設置排序類型, 非 0 值則降序
@strWhere varchar(1500) = '' -- 查詢條件 (注意: 不要加 where)
AS
declare @strSQL varchar(5000) -- 主語句
declare @strTmp varchar(110) -- 臨時變量
declare @strOrder varchar(400) -- 排序類型
if @doCount != 0
begin
if @strWhere !=''
set @strSQL = 'select count(*) as Total from [' + @tblName + '] where '+@strWhere
else
set @strSQL = 'select count(*) as Total from [' + @tblName + ']'
end
--以上代碼的意思是如果@doCount傳遞過來的不是0，就執行總數統計。以下的所有代碼都是@doCount為0的情況
else
begin
if @OrderType != 0
begin
set @strTmp = '<(select min'
set @strOrder = ' order by [' + @fldName +'] desc'
--如果@OrderType不是0，就執行降序，這句很重要！
end
else
begin
set @strTmp = '>(select max'
set @strOrder = ' order by [' + @fldName +'] asc'
end
if @PageIndex = 1
begin
if @strWhere != ''
set @strSQL = 'select top ' + str(@PageSize) +' '+@strGetFields+ ' from [' + @tblName + '] where ' + @strWhere + ' ' + @strOrder
else
set @strSQL = 'select top ' + str(@PageSize) +' '+@strGetFields+ ' from ['+ @tblName + '] '+ @strOrder
--如果是第一頁就執行以上代碼，這樣會加快執行速度
end
else
begin
--以下代碼賦予了@strSQL以真正執行的SQL代碼
set @strSQL = 'select top ' + str(@PageSize) +' '+@strGetFields+ ' from ['
+ @tblName + '] where [' + @fldName + ']' + @strTmp + '(['+ @fldName + ']) from (select top ' + str((@PageIndex-1)*@PageSize) + ' ['+ @fldName + '] from [' + @tblName + ']' + @strOrder + ') as tblTmp)'+ @strOrder
if @strWhere != ''
set @strSQL = 'select top ' + str(@PageSize) +' '+@strGetFields+ ' from ['
+ @tblName + '] where [' + @fldName + ']' + @strTmp + '(['
+ @fldName + ']) from (select top ' + str((@PageIndex-1)*@PageSize) + ' ['
+ @fldName + '] from [' + @tblName + '] where ' + @strWhere + ' '
+ @strOrder + ') as tblTmp) and ' + @strWhere + ' ' + @strOrder
end
end
exec (@strSQL)
GO

復制代碼 代碼如下:

DECLARE @strSQL varchar(8000)
DECLARE @strWhere varchar(1000)
SET @strWhere = 'UserName LIKE ''%Jim'' dog%'''
set @strSQL = 'SELECT TOP 20 * from [UserAccount] where ' + @strWhere + ' ORDER BY ID DESC'
print @strSQL
exec (@strSQL)
