sql server 带输入输出参数的分页存储过程（效率最高）

create procedure proc_page_withtopmax
(
@pageIndex int,--页索引
@pageSize int,--每页显示数
@pageCount int output,--总页数，输出参数
@totalCount int output--总条数
)
as
begin
set nocount on;

declare @sql nvarchar(1000)
set @sql=‘select top 10 * from tb_testtable where (id> (select
max(id) from (select top ‘+str((@pageIndex-1)*@pageSize)+‘ id from
tb_testtable order by id) as temp)) order by id‘
execute(@sql)

declare @sqlRecordCount nvarchar(1000) --得到总记录条数的语句
set @sqlRecordCount=N‘select @recordCount=count(*) from tb_testtable‘
declare @recordCount int --保存总记录条数的变量
exec sp_executesql @sqlRecordCount,N‘@recordCount int output‘,@recordCount output

if( @recordCount % @pageSize = 0) --如果总记录条数可以被页大小整除
set @pageCount = @recordCount / @pageSize --总页数就等于总记录条数除以页大小
else --如果总记录条数不能被页大小整除
set @pageCount = @recordCount / @pageSize + 1 --总页数就等于总记录条数除以页大小加1

set @totalCount = @recordCount

set nocount off;
end

--数据库中执行该存储过程
declare @pageCount int, @totalCount int

exec proc_page_withtopmax 2,95955,@pageCount output,@totalCount output

select ‘总页数:‘+str(@pageCount)
select ‘总条数:‘+str(@totalCount)

C# 代码调用该带输入输出参数的分页存储过程

public static DataSet GetRecordByPage( int pageSize, int pageIndex, out int pageCount, out int totalCount)
{
DataSet ds = new DataSet();
try
{
using (SqlConnection conn = new SqlConnection(@"server=;database=data_test;uid=; pwd=;"))
{
SqlCommand cmd = new SqlCommand();
cmd.Connection = conn;
cmd.Parameters.Add(new SqlParameter("@pageSize", SqlDbType.Int));
cmd.Parameters.Add(new SqlParameter("@pageIndex", SqlDbType.Int));
SqlParameter param = new SqlParameter("@totalCount", SqlDbType.Int);
param.Direction = ParameterDirection.Output;
cmd.Parameters.Add(param);

SqlParameter param1 = new SqlParameter("@pageCount", SqlDbType.Int);
param1.Direction = ParameterDirection.Output;
cmd.Parameters.Add(param1);

cmd.Parameters[0].Value = pageSize;
cmd.Parameters[1].Value = pageIndex;
cmd.Parameters[2].Value = 0;
cmd.Parameters[3].Value = 0;

cmd.CommandType = CommandType.StoredProcedure;
cmd.CommandText = "proc_page_withtopmax";
cmd.CommandTimeout = 180;

SqlDataAdapter adapter = new SqlDataAdapter();
adapter.SelectCommand = cmd;

DataSet source = new DataSet();
adapter.Fill(ds);

object o = cmd.Parameters["@totalCount"].Value;
totalCount = (o == null || o == DBNull.Value) ? 0 : System.Convert.ToInt32(o);

object b = cmd.Parameters["@pageCount"].Value;
pageCount = (b == null || o == DBNull.Value) ? 0 : System.Convert.ToInt32(b);
}
}
catch (SqlException e)
{
throw e;
}
return ds;
}

}
