调用方法:

strTable=" [TableName] " "数据表名称

strKeyField="Field1" "主键:这里假设Field1为主键
strWhere="" "条件:FieldA="b"
strOrderType=1 "排序方式:1为倒序,0为顺序

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
