调用方法：

有用的朋友请自己慢慢调试吧，总记录是用ASP来取的，存储在SESSION里边，如果每次都统计一次总记录，将会非常费时，当然，如果你想在存储过程里来取总记录和总页数然后返回也是可以的，下边是代码：
--获取记录总数--
SET @tmpSQL='SELECT @getRecordCounts=COUNT('+@strKeyField+') FROM '+@strTable+@tmpWhere
EXEC sp_executesql @tmpSQL,N'@getRecordCounts int output',@getRecordCounts OUTPUT
--获取总页数--
SET @tempFolatNumber=@getRecordCounts%@IntPageSize
IF @getRecordCounts<=@IntPageSize
SET @getPageCounts=1
ELSE
BEGIN
IF @tempFolatNumber != 0
SET @getPageCounts=(@getRecordCounts/@IntPageSize)+1
ELSE
SET @getPageCounts=(@getRecordCounts/@IntPageSize)
END
别忘了返回定义参数：
@getRecordCounts int output,--返回总记录
@getPageCounts int output--返回总页数 |
