在使用 odp.net 将 Oracle 对象类型映射为 C# 中的类后,将类传回存储过程以将数据插入到表中,所有具有数字数据的属性为空。我们没有收到任何例外。附上代码如下。我正在使用 oracle 9i 和 asp.net v2。

新观察: 我观察到,如果我的变量的类型是 number(1),它会以与以下相同的结构正确插入,但对于其他情况,如 Number、Number(4)、Number(3,2),所有值都是空的。

在下面的示例中,插入后下面的列是空的:

  1. 订购
  2. ON_VERSION
  3. ON_VERSION1
  4. ON_VERSION

但其他变量完全插入。

  • 当我在 oracle DB 中读取发送项目到我的函数时,不包括数字。类型结构:

    创建或替换类型 CMMT_OBJECTS_TYPE 是对象(OV_FIX_REF_NO VARCHAR2(40)、ON_ORDER NUMBER(4)、OV_OBJECT_NAME VARCHAR2(100)、OV_CATEGORY VARCHAR2(12)、OV_SCOPE VARCHAR2(12)、OV_TYPE VARCHAR2(12)、OV_LASTUPD_USER VARCHAR2(40)、 OV_LASTUPD_PROG VARCHAR2(40)、OD_LASTUPD 日期、OV_LOCATION VARCHAR2(40)、OV_REMARKS VARCHAR2(4000)、ON_VERSION NUMBER(10,3)、ON_VERSION1 NUMBER(10,3)、OV_OBJECT_CLASSIFICATION VAR_CHAR2(5)、OV_OBJECT_REGION VARCHAR2(5) VARCHAR2(3), ON_VERSION2 NUMBER, ON_VERSION3 VARCHAR2(20) ); /

执行您的参数后,我找到了答案

cmd.ExecuteNonQuery();

它导致您的类型类中的 ToCustomObject 函数由 odp.net 在 VS 中生成,并且在该函数中为所有数据和数字您有一个与您的数字或数据参数名称相同的参数作为 bool 类型。此变量以您的列名开头并以 IsNull 结尾

OD_SUBMITTEDIsNull

设置 DATA 或 Number 变量的值后,应将此参数设置为 true。

就这样 :)

OD_SUBMITTEDIsNull = 真;
