记录Access数据库更新操作大坑一个

　　对于更新Access数据库的操作，必须保持参数数组与sql语句中参数顺序一致，如下：

  public bool Update(MyModel model)
         {
             StringBuilder strSql = new StringBuilder();
             strSql.Append("update table1 set ");
             strSql.Append(" column1 = @column1 , ");
             strSql.Append(" column2 = @column2, ");
             strSql.Append(" where ID=@ID ");

             OleDbParameter[] parameters =
                 {
                     // 必须要这个顺序 ヾ(。￣□￣)ﾂ゜゜゜
                     new OleDbParameter("@column1", OleDbType.Integer, ),
                     new OleDbParameter("@column2", OleDbType.Integer, ),
                     new OleDbParameter("@ID", OleDbType.Integer, )
                 };

             parameters[].Value = model.column1;
             parameters[].Value = model.column1;
             parameters[].Value = model.ID;

             int rows = DbHelperOleDb.ExecuteSql(strSql.ToString(), parameters);
             if (rows > )
             {
                 return true;
             }
             else
             {
                 return false;
             }
         }

　　如果改成下面这样，顺序不一致了，就妥妥的更新失败，还不报任何异常。。。。

         public bool Update(MyModel model)
         {
             StringBuilder strSql = new StringBuilder();
             strSql.Append("update table1 set ");
             strSql.Append(" column1 = @column1 , ");
             strSql.Append(" column2 = @column2, ");
             strSql.Append(" where ID=@ID ");

             OleDbParameter[] parameters =
                 {
                     // 顺序与sql语句不一致了 ヾ(。￣□￣)ﾂ゜゜゜
                     new OleDbParameter("@ID", OleDbType.Integer, ),
                     new OleDbParameter("@column1", OleDbType.Integer, ),
                     new OleDbParameter("@column2", OleDbType.Integer, )
                 };

             parameters[].Value = model.ID;
             parameters[].Value = model.column1;
             parameters[].Value = model.column1;

             int rows = DbHelperOleDb.ExecuteSql(strSql.ToString(), parameters);
             if (rows > )
             {
                 return true;
             }
             else
             {
                 return false;
             }
         }
