C# 利用聚合函数MIN求销售额、利润最少的商品
C# 利用聚合函数MIN求销售额、利润最少的商品,具体来说是查询利润最少的商品信息,查询销售额最少的商品信息,查询结果将绑定显示于DataGridView数据网格控件中。
下面以查询销售额最少的商品信息为例,帖出具体的代码实现:
private DataTable GetMoney()
{
string P_Str_ConnectionStr = string.Format(//创建数据库连接字符串
@"server=WIN-GI7E47AND9RLS;database=db_TomeTwo;uid=sa;pwd=");
string P_Str_SqlStr = string.Format(//创建SQL查询字符串
"SELECT * FROM tb_Ware WHERE 销价 IN(SELECT MIN(销价) FROM tb_Ware)");
SqlDataAdapter P_SqlDataAdapter = new SqlDataAdapter(//创建数据适配器
P_Str_SqlStr, P_Str_ConnectionStr);
DataTable P_dt = new DataTable();//创建数据表
P_SqlDataAdapter.Fill(P_dt);//填充数据表
return P_dt;//返回数据表
}
其它部分的查询请下载本源码包。
