在 odp.net 上使用带有 number 属性的 oracle 对象类型

【中文标题】在 odp.net 上使用带有 number 属性的 oracle 对象类型【英文标题】：using oracle object type with number attribute on odp.net 【发布时间】：2013-06-17 12:10:12 【问题描述】：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)，所有值都是 null。
在下面的示例中，插入后下面的列是空的：
-
ON_ORDER
ON_VERSION
ON_VERSION1
ON_VERSION
但其他变量已完全插入。
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 VARCHAR2(5), OV_OBJECT_REGION VARCHAR2(5), OV_OBJECT_TYPE VARCHAR2(3), ON_VERSION2 号， ON_VERSION3 VARCHAR2(20) ); /

【问题讨论】：
您是否考虑过仅使用您遇到问题的字段类型制作一个较小的表和 proc？你会更容易缩小你的问题范围，让人们通过一个小代码 sn-p 比你发布的大量代码更合理。 @TomHalladay，感谢汤姆的回复，Juat 检查 int 值，我所有的 int 值都以 ON_ 开头，我知道我所有的 num 变量都没有插入 :( 看起来像一些铸造有问题。 @TomHalladay：我的问题是除了 int column(number) 之外的所有内容都正确插入 【参考方案1】：执行你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布尔类型。这个变量以你的列名开始，以 IsNull 结束
OD_SUBMITTEDIsNull
在设置 DATA 或 Number 变量的值后，应将此参数设置为 true。
就是这样:)
OD_SUBMITTEDIsNull = true;
