sql server 带输入输出参数的分页存储过程(效率最高)

it2022-05-07  0

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)asbeginset 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; }

}
