'GoodsPrice' 附近有语法错误。

源错误:

*行 48:         int i = comm.ExecuteNonQuery();

行 50:         BindData(); system string --------------------编程问答-------------------- string upstr = "update Good set GoodsName='" + GoodsName + "', GoodsPrice= " + GoodsPrice + ", GoodsNumber= " + GoodsNumber + ",GoodsKind= '" + GoodsKind + "' where GoodsID=" + GoodsID;

试试这样还有错误吗 --------------------编程问答-------------------- 你这SQL语法都不对啊

注意数字类型的，不用单引号 --------------------编程问答--------------------   string upstr = "update Good set GoodsName='" + GoodsName + "' GoodsPrice= '" + GoodsPrice + "' GoodsNumber= '" + GoodsNumber + "'GoodsKind= '" + GoodsKind + "'where GoodsID=" + GoodsID;

这要逗号吗
  string upstr = "update Good set GoodsName='" + GoodsName + "'，GoodsPrice= '" + GoodsPrice + "',GoodsNumber= '" + GoodsNumber + "'GoodsKind= '" + GoodsKind + "'where GoodsID=" + GoodsID; --------------------编程问答-------------------- 每个更新字段后要加逗号，数字类型加不加引号都没关系 --------------------编程问答--------------------

--------------------编程问答-------------------- this.GridView1.DataKeyNames = new string[] { "GoodsID" }; 改为 this.GridView1.DataKeyNames = new string[] {GoodsID}; 试试看 --------------------编程问答--------------------



string upstr =

                String.Format(

                    "update Good set GoodsName='{0}', GoodsPrice= '{1}', GoodsNumber= '{2}', GoodsKind= '{3}' where GoodsID={4}",

                    GoodsName, GoodsPrice, GoodsNumber, GoodsKind, GoodsID);

补充：.NET技术 ,  ASP.NET
