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;

}

}
