What I need to do is to pass a C# DataTable to an Oracle stored procedure. Here is what I have done: Oracle side: Created a type: create or replace TYPE CUSTOM_TYPE AS OBJECT ( attribute1 VARCHAR(10), attribute2 VARCHAR(10) ); Created a table create or replace TYPE CUSTOM_TYPE_ARRAY AS TABLE OF CUSTOM_TYPE; Created a stored procedure create or replace PROCEDURE SP_TEST (
我需要做的是将C＃DataTable传递给Oracle存储过程。 这是我所做的： Oracle方面： 创建一个类型： create or replace TYPE CUSTOM_TYPE AS OBJECT ( attribute1 VARCHAR(10), attribute2 VARCHAR(10) ); 创建了一张桌子 create or replace TYPE CUSTOM_TYPE_ARRAY AS TABLE OF CUSTOM_TYPE; 创建一个存储过程 create or replace PROCEDURE SP_TEST ( P_TABLE_IN IN CUSTOM_TYPE_ARRAY, P_RESULT_OUT
To call a stored procedure with output parameters from C#, I need to obtain the datatype and the size of the respective parameters. I am using the Oracle.DataAccess library. How can I get this information from stored procedure metadata on an Oracle database? Someone gave the tables to query for SQL Server in this answer (How to determine size property for stored procedure output parameters in
要使用C＃中的输出参数调用存储过程，我需要获取数据类型和各个参数的大小。 我正在使用Oracle.DataAccess库。 如何从Oracle数据库的存储过程元数据获取此信息？ 有人给这个表在这个答案中查询SQL Server（如何确定C＃数据访问层中的存储过程输出参数的size属性），但是我期待在Oracle中调用存储过程。 这是查询select a.OBJECT_NAME, data_type, sequence, in_out, data_length, data_precision, Data_scale, radix from U
i've got an issue in c# executing an Oracle Stored Procedure using Oracle.DataAccess library. In oracle I've got this structure; CREATE OR REPLACE TYPE O_MOV_LST_STA_STATUS AS TABLE OF O_MOV_STATION_STATUS;o_mov_lst_sta_status And the type description is as follows: CREATE OR REPLACE TYPE O_MOV_STATION_STATUS AS OBJECT ( StationT NUMBER(10), StationN
我在使用Oracle.DataAccess库执行Oracle存储过程的c＃中遇到了一个问题。 在oracle中我有这个结构; CREATE OR REPLACE TYPE O_MOV_LST_STA_STATUS AS TABLE OF O_MOV_STATION_STATUS;o_mov_lst_sta_status 类型描述如下： CREATE OR REPLACE TYPE O_MOV_STATION_STATUS AS OBJECT ( StationT NUMBER(10), StationN NUMBER(10), Stat NUMBER(3), Loaded
I have an Oracle stored procedure named CREATE_CASE_EXL : PROCEDURE CREATE_CASE_EXL(P_RICdata RICTab, P_sACTION_TYPE IN VARCHAR2); where RICTab is a custom type: TYPE RICTab IS TABLE OF MMSRRicRec INDEX BY BINARY_INTEGER; TYPE MMSRRicRec IS RECORD ( RIC VARCHAR2(32), FID_NO NUMBER(8), REC_ID NUMBER(8), MMS_ACTION VARCHAR2(1) ); I run this co
我有一个名为CREATE_CASE_EXL的Oracle存储过程： PROCEDURE CREATE_CASE_EXL(P_RICdata RICTab, P_sACTION_TYPE IN VARCHAR2); RICTab是一种自定义类型： TYPE RICTab IS TABLE OF MMSRRicRec INDEX BY BINARY_INTEGER; TYPE MMSRRicRec IS RECORD ( RIC VARCHAR2(32), FID_NO NUMBER(8), REC_ID NUMBER(8), MMS_ACTION VARCHAR2(1) ); 我在PL / SQL中运行这段代码来执
I've seen many people use the following code: Type t = typeof(obj1); if (t == typeof(int)) // Some code here But I know you could also do this: if (obj1.GetType() == typeof(int)) // Some code here Or this: if (obj1 is int) // Some code here Personally, I feel the last one is the cleanest, but is there something I'm missing? Which one is the best to use, or is it persona
我见过很多人使用下面的代码： Type t = typeof(obj1); if (t == typeof(int)) // Some code here 但我知道你也可以这样做： if (obj1.GetType() == typeof(int)) // Some code here 或这个： if (obj1 is int) // Some code here 就我个人而言，我觉得最后一个是最干净的，但有什么我失踪？ 哪一个最好用，还是个人喜好？ 一切都不一样。 typeof需要一个类型名称（在编译时指定）。 GetType获取实例的
With reference to Oracle: Variable number of parameters to a stored procedure I have s stored procedure to insert multiple Users into a User table. The table is defined like: CREATE TABLE "USER" ( "Name" VARCHAR2(50), "Surname" VARCHAR2(50), "Dt_Birth" DATE, ) The stored procedure to insert multiple Users is: type userType is record ( name varchar2(100), ... ); type userL
参考Oracle：存储过程的可变参数数量 我有存储过程将多个用户插入到用户表中。 该表的定义如下所示： CREATE TABLE "USER" ( "Name" VARCHAR2(50), "Surname" VARCHAR2(50), "Dt_Birth" DATE, ) 存储过程插入多个用户是： type userType is record ( name varchar2(100), ... ); type userList is table of userType index by binary_integer; procedure array_insert (p_userList in userList) is be
I'm wondering about how to do validation the mvvm way. I saw lots of content on this topic on the web, but nothing seems to cover my situation, but maybe I'm just approaching it the wrong way. I have a ValidableModel base class from which my other models inherit: public abstract class ValidableModel : IDataErrorInfo { protected Type _type; protected readonly Dictionary<strin
我想知道如何验证mvvm的方式。 我在网络上看到了关于这个主题的大量内容，但似乎没有涵盖我的情况，但也许我只是以错误的方式接近它。 我有一个从其他模型继承的ValidableModel基类： public abstract class ValidableModel : IDataErrorInfo { protected Type _type; protected readonly Dictionary<string, ValidationAttribute[]> _validators; protected readonly Dictionary<string, PropertyInfo&g
I am going through some MVVM articles, primarily this and this. My specific question is: How do I communicate Model changes from the Model to the ViewModel? In Josh's article, I don't see that he does this. The ViewModel always asks the Model for properties. In Rachel's example, she does have the model implement INotifyPropertyChanged , and raises events from the model, but they
我正在浏览一些MVVM文章，主要是这个和这个。 我的具体问题是： 如何将模型更改从模型传递给ViewModel？ 在乔希的文章中，我没有看到他这样做。 ViewModel总是要求模型的属性。 在Rachel的例子中，她的模型实现了INotifyPropertyChanged ，并且引发了模型中的事件，但它们被视图本身所使用（请参阅她的文章/代码以获取更多关于她为什么这样做的更多细节）。 我看不到任何模型提示ViewModel对模型属性所做更改的示例。
I'm trying to learn WPF and the MVVM problem, but have hit a snag. This question is similar but not quite the same as this one (handling-dialogs-in-wpf-with-mvvm)... I have a "Login" form written using the MVVM pattern. This form has a ViewModel which holds the Username and Password, which are bound to the view in the XAML using normal data bindings. It also has a "Login&
我试图学习WPF和MVVM问题，但遇到了一些障碍。 这个问题与这个问题类似但不完全相同（处理-wpf-with-mvvm中的对话框）... 我有一个使用MVVM模式编写的“登录”表单。 这个表单有一个ViewModel，它保存着用户名和密码，它们使用普通的数据绑定绑定到XAML中的视图。 它还有一个“登录”命令，它绑定到表单上的“登录”按钮，使用普通的数据绑定。 当“Login”命令触发时，它会调用ViewModel中的一个函数，该函数将关闭并通过网络发
I have a reportviewer in windows form application which is showing RDLC report. I need to copy a text of that report and save it in notepad. Can anybody help? eg I need to copy the text "LiFTER ASSY" only, but without exporting directly from reportviewer itself. You either export or copy it yourself by typing. It's read-only the generated report. You can export the report t
我在Windows窗体应用程序中显示了一个reportviewer，它显示RDLC报告。 我需要复制该报告的文本并将其保存在记事本中。 任何人都可以帮忙吗？ 例如，我只需要复制文本“LiFTER ASSY”，但不直接从reportviewer本身导出。 您可以通过输入来自行导出或复制它。 它是只读生成的报告。 您可以将报告导出为pdf，excel或word。 从那里你可以尝试复制文本。 自2005年以来，我一直在等待这个功能！ 我发现的唯一工作周是使用R
