我正在使用xml表。我的日期类型列有问题。有人可以查看我的代码并告诉我我的代码有什么问题，因为我无法弄明白。

我的表TBL_EMP_BASIC_PROFILE是：

Name                  Null     Type          
--------------------- -------- ------------- 
EBASP_ID              NOT NULL VARCHAR2(10)  
EBASP_NAME                     VARCHAR2(50)  
B_EBASP_NAME                   VARCHAR2(150) 
EBASP_GENDER                   VARCHAR2(8)   
EBASP_CATEGORY                 VARCHAR2(10)  
EBASP_REGION_TYPE              VARCHAR2(20)  
EBASP_REGION_NAME              VARCHAR2(50)  
EBASP_SUB_REGION               VARCHAR2(50)  
EBASP_LOCATION                 VARCHAR2(100) 
EBASP_DESIGNATION              VARCHAR2(50)  
B_EBASP_DESIGNATION            VARCHAR2(150) 
EBASP_DATE_OF_JOINING          DATE          
EBASP_GRADE                    NUMBER(2)     
EBASP_BASIC                    NUMBER(7)     
EBASP_PHOTO_UPLOAD             VARCHAR2(500) 
EBASP_CREATED_ON               DATE          
EBASP_CREATED_BY               VARCHAR2(10)

我的套餐功能是：

                                          ebasp_created_by VARCHAR2(50) PATH 'ebasp_created_by')temp1;
ret:=to_char(sql%rowcount);  
COMMIT;

RETURN '<result><status affectedRow='||ret1||'>Success</status></result>';
DBMS_OUTPUT.PUT_LINE(ret);
EXCEPTION
WHEN OTHERS THEN
v_code := SQLCODE;
v_errm := SUBSTR(SQLERRM, 1 , 500);
DBMS_OUTPUT.PUT_LINE('Error code ' || v_code || ': ' || v_errm);
RETURN '<result><status>Error'||v_errm||'</status></result>';
END save_emp_basic_profile;

我的输入pl sql是：

declare
  query_result clob;
begin
  query_result := *package_name*.SAVE_EMP_BASIC_PROFILE
  ('<employees>
    <employee>
        <ebasp_id>1234567890</ebasp_id>

        <b_econt_postal_code></b_econt_postal_code>
        <econt_district></econt_district>
    </employee>
</employees>');
end;

仅提供id和1个日期作为输入（id必须作为主键）。但是我收到了这个错误：Error code -1858: ORA-01858: a non-numeric character was found where a numeric was expected。有人可以告诉我在日期类型列中输入日期的正确方法。因为我尝试过to_date（）函数但没有好处。

不要将to_date放在你的xml中;这样，你就可以拔出字符串＆＃34; to_date（＆＃39;＆＃39; 2-2-2016＆＃39;＆＃39;＆＃39;＆＃39;＆＃39; DD-MM -YYYY＆＃39;＆＃39;）＆＃34;您当时希望转换成日期 - 即。 insert into tbl_emp_basic_profile -- where is the list of columns? You should explicitly list the columns you're inserting into, esp in production code! select ebasp_id, ebasp_name, b_ebasp_name, ebasp_gender, ebasp_category, ebasp_region_type, ebasp_region_name, ebasp_sub_region, ebasp_location, ebasp_designation, b_ebasp_designation, to_date(ebasp_date_of_joining, 'dd-mm-yyyy') ebasp_date_of_joining, ebasp_grade, ebasp_basic, ebasp_photo_upload, to_date(ebasp_created_on, 'dd-mm-yyyy') ebasp_created_on, ebasp_created_by from xmltable('/employees/employee' passing xmldata columns ebasp_id varchar2(10) path 'ebasp_id', ebasp_name varchar2(50) path 'ebasp_name', b_ebasp_name varchar2(150) path 'b_ebasp_name', ebasp_gender varchar2(8) path 'ebasp_gender', ebasp_category varchar2(10) path 'ebasp_category', ebasp_region_type varchar2(50) path 'ebasp_region_type', ebasp_region_name varchar2(50) path 'ebasp_region_name', ebasp_sub_region varchar2(50) path 'ebasp_sub_region', ebasp_location varchar2(100) path 'ebasp_location', ebasp_designation varchar2(50) path 'ebasp_designation', b_ebasp_designation varchar2(150) path 'b_ebasp_designation', ebasp_date_of_joining varchar2(10) path 'ebasp_date_of_joining', ebasp_grade number(2) path 'ebasp_grade', ebasp_basic number(7) path 'ebasp_basic', ebasp_photo_upload varchar2(500) path 'ebasp_photo_upload', ebasp_created_on varchar2(10) path 'ebasp_created_on', ebasp_created_by varchar2(50) path 'ebasp_created_by') temp1; 我认为你可以看到它是一个非首发。

相反，将日期保留为字符串，例如：... listener = new TcpListener(System.Net.IPAddress.Any, 4711); listener.Start(); while(true){ TcpClient c = listener.AcceptTcpClient(); } ... ，将xmltable中列的数据类型更改为varchar2，然后将转换作为插入的一部分进行转换，如下所示：

...
TcpClient c = new TcpClient("myip", 4711);
StreamReader inStream = new StreamReader(c.GetStream());
...

更好的做法是将每个日期使用的日期掩码作为XML中每个日期节点的属性，这样您就不必事先知道日期字符串的格式;这样，如果生成的xml想要改变它们格式化日期的方式，它应该对数据库不可见。我知道可能无法让XML生成器添加它。

在您的代码中使用to_char而不是to_date（'2-2-2016'，'DD-MM-YYYY'）。也许这就是错误的来源？
