小编Joa*_*eno的帖子

一直试图解决这个问题几个小时......

string date = "2009-09-23T13:00:00"

DateTime t = new DateTime();
t = DateTime.ParseExact(date, "HH:mm", null);

此例外的结果:

System.FormatException未处理Message ="String未被识别为有效的DateTime."

好的...所以我有一个页面,根据查询字符串列出表格中的产品.

因此,如果我说foo.aspx？fam = 1,将列出来自家庭1的所有产品.

如果查询字符串为空,如何使我的代码列出所有值？

我的SQL命令必须是不同的...不能真正看到我如何做到这一点.

<asp:SqlDataSource ID="ds_produtos" runat="server" 
   ConnectionString="<%$ ConnectionStrings:LocalSqlServer2 %>" 

    SelectCommand="SELECT DISTINCT [IdProduct], [Name], [Description], [IdFamily], [Price],  [Stock] FROM [Product] WHERE ([IdFamily] = @IdFamily )">
    <SelectParameters>
        <asp:QueryStringParameter Name="IdFamily" QueryStringField="fam" Type="Int32" />
    </SelectParameters>
</asp:SqlDataSource>

我收到错误(8,3):PL/SQL:忽略SQL语句和错误(8,10):PL/SQL:ORA-00904:"XMLELEMENT":以下过程中的标识符无效:

    CREATE OR REPLACE PROCEDURE GETXMLTREE
    (
      p_ESTABELECIMENTOID IN NUMBER  
    , MYXML OUT VARCHAR2  
    )
    AS
    BEGIN
    SELECT XMLELEMENT --line 8
    into MYXML
        ("root",
          (select dbms_xmlgen.getxmltype 
            (dbms_xmlgen.newcontextfromhierarchy
              ('SELECT level,
                XMLElement("item",XMLAttributes(osusr_kfa_estabele.id as "id"),
                  XMLElement("content", XMLElement("name", nomecompleto)))          
                  from osusr_kfa_estabele
                  start with osusr_kfa_estabele.id = p_ESTABELECIMENTOID 
                  connect by nocycle prior osusr_kfa_estabele.id = osusr_kfa_estabele.estabelecimetnopaiid' ))
          from dual))
    from dual;

    END GETXMLTREE;

为什么会发生这种情况的任何线索？谢谢
