使用odp.net将Oracle Object Type映射为C＃中的Class之后，将类传递回存储过程以将数据插入表中，所有具有数字数据的属性都为空。我们没有收到任何例外。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数字（1），它使用与下面相同的结构正确插入，但对于其他情况，如Number，Number（4），Number（3,2），所有值都为null。
插入后，下面示例中的列为空：
但完全插入了其他变量。
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 VARCHAR2（5）， OV_OBJECT_REGION VARCHAR2（5）， OV_OBJECT_TYPE VARCHAR2（3）， ON_VERSION2 NUMBER， ON_VERSION3 VARCHAR2（20） ）; /

答案 0 :(得分：-1)
执行参数
后，我找到了答案cmd.ExecuteNonQuery();
它导致了你的类型类中的ToCustomObject函数，该函数类是由VS中的odp.net生成的，并且在该函数中，对于所有数据和数字，你有一个与你的数字或数据参数同名的参数作为bool类型。此varriable以列名开头，以IsNull
结束OD_SUBMITTEDIsNull
设置DATA或Number变量的值后，应将此参数设置为true。
这就是全部：）
OD_SUBMITTEDIsNull = true;
