通用的可带查询条件的SQL语句的分页存储过程（2）

代码二：

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, – 页尺寸

@PageIndex int = 1, – 页码

@doCount bit = 0, – 返回记录总数, 非 0 值则返回

@OrderType bit = 0, – 设置排序类型, 非 0 值则降序

@strWhere varchar(1500) = ” – 查询条件 (注意: 不要加 where)

AS

declare @strSQL varchar(5000) – 主语句

declare @strTmp varchar(110) – 临时变量

declare @strOrder varchar(400) – 排序类型

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

–以上代码的意思是如果@doCount传递过来的不是0，就执行总数统计。以下的所有代码都是@doCount为0的情况

else

begin

if @OrderType != 0

begin

set @strTmp = ‘<(select min’

set @strOrder = ’ order by [’ + @fldName +’] desc’

–如果@OrderType不是0，就执行降序，这句很重要！

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

–如果是第一页就执行以上代码，这样会加快执行速度

end

else

begin

–以下代码赋予了@strSQL以真正执行的SQL代码

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

/*

– 需要传递的参数

@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, – 页尺寸

@PageIndex int = 1, – 页码

@doCount bit = 0, – 返回记录总数, 非 0 值则返回

@OrderType bit = 0, – 设置排序类型, 非 0 值则降序

@strWhere varchar(1500) = ” – 查询条件 (注意: 不要加 where)

– 调用测试

exec pagination @tblName=’jobs’, @strGetFields=’job_id,job_desc,min_lvl,max_lvl’,

@fldName=’job_id’,@PageSize=3,@PageIndex=1,

@doCount=0,@OrderType=1,@strWhere=”
