Any new release plan?
Is there any release plan for the next version of the ibatis for .NET ?
Re: Next Release
For me: 1) for 1.6.2 beta, I'd like to see a GA version with JIRA checked if there's any bug for it. 2) an new version with 1.6.x with QueryForDataTable, Castle.DynamicProxy2 is a bouns but not a must. 3) I don't mind the breaking changes currently in V3. ISqlMapper is designed to be singleton-per-thread in 1.6.x, the 3.x code in repository addresses this issue and provides a more flexible connection management model. It will be better to keep these broken changes and I think it is easy to add a wrapper that acts as ISqlMapper in 1.6.x. 4) I think the IMapperFactory interface in V3 can be discarded for some reasons: a) to keep the simplicity of iBATIS.NET b) Visual Studio provides powerful DSL tools. IMapperFactory can be easily complished with generative programming by user rather than in iBATIS.NET. 5) NUnit 2.5 enables generic test, it will simplifies writing tests for testing iBATIS on different database.

Re: Oracle Return SYS_REFCURSOR Issue
I have used oracle in serveral years but not with iBATIS.
The GetWidgets function has a return parameter. As Oracle support function
overloads, it can not find a function named as GetWidgets with no
parameter.
I guess you should define a parameterMap.
You may also try the ODBC call syntax.

Re: Castle.DynamicProxy2

I managed to port it and in addition remove the CachedProxyGenerator class ( and a couple others) because DynamicProxy2 seems to do its own TypeCaching. It works and all the nunit tests pass.

Re: IBATIS.NET - V3- Gets the IDataMapper from an IMapperFactory looks very strange
After reading
http://opensource.atlassian.com/confluence/oss/display/IBATIS/iBATIS+3.0+Whiteboard
and the iBATIS v3 java code, I think:
MapperFactory.GetMapperT is intended to create proxies of Mapper
interfaces. A mapper interface is a interface that defines data access
methods for a specific data object type. Such as:
public interface ICustomerMapper
{
IListCustomer FindByName(String name);
}
The implementation of GetMapperICustomerMapper will create a dynamic proxy
that implements FindByName as to invoke
IDataMapper.Select(ICustomer-FindByName, new Hashtable(name,
nameValue)).
The ICustomer-FindByName may be defined as something like:
select id=ICustomerMapper-FindByName
parameterClass=Hashtable/select

Re: Dirty Tracking Issue
I have a new solution based on a custom ISetAccessor rather than the
IObjectFactory.
As the IBatisNet use ISetAccessor to set the value of a property, we can use
a custom ISetAccessor saves the IsDirty state before actually set the
property value and restore it later.
I attach the unit test.
Hope it works for you.

If you wanna to use the constructor solution, note that all auto-properties
must be replaced by a normal property with a backend field. for example:
public String Name { get; set; }
must be replaces with a normal property like:
private String m_Name;
public String Name { get { return m_Name;} set { m_Name = value;}}
and the constructor should set the value to the m_Name field instead of
the property.

I also imagine that it would limit iBATIS.NET's evolution options in the future, such as precluding the ability to pre-generate code files instead of inspecting an XML configuration at start up.

Re: Dirty Tracking Issue
We can bypass to set 'dirty' if the AOP generation mechanism can know an
object is in 'loading' state.
We can use a custom IBatisNet.Common.Utilities.IObjectFactory to mark an
object 'loading'.
And we can use a wrapped ISqlMapper to clean the 'loading' flag as:
public object QueryForObject(string statementName, object parameterObject) {
Object result = originalSqlMapper.QueryForObject(...);
result.IsLoading = false;
return result;
}

In the code snippet below (bold text), ANSWERTEXT field is of type Varbinary. While inserting data to this field, I used convert function. INSERT INTO SecretAnswer(ParticipantId, QuestionId, QuestionCode, ANSWERTEXT) SELECT ParticipantId, #questionId#, #QuestionCode#, CONVERT(varbinary(255),#Answer#) From table.(some join conditions) Case 1. In case of 'Answer' being a normal alpha numeric string test123, it converts the string to varbinary properly and while validating, I am able to validate properly. select convert(varchar(100), answer) from table Result: test123 Case 2. In case of 'Answer' having any special character (e.g. apostrophe), it does the same. However, when I execute the following in query analyzer, the result is not equal to the original string. E.g. Answer = test'123 Inserted this using above insert statement. Executed following: select convert(varchar(100), answer) from table The result comes only single char: t While select convert(nvarchar(100), answer) from table, returns test'123, which is a problem. Can someone look into this and respond accordingly?

Embed inline-parameter-map in simple-dynamic-sql element?
Hi, How to make the IBatis.NET support embedding inline-parameterpmap in simple-dynamic-sql element ? For example, I have the following pseudocode: == in the sql map: select id=DynamicSqlStatement resultClass=System.Collections.IDictionary parameterClass=String $__DynamicSql$ /select and in code: Hashtable paramObject = new Hashtable(); paramObject.Add(__DynamicSql, SELECT CATALOG_NAME, SCHEMA_NAME FROM INFORMATION_SCHEMA.SCHEMATA WHERE (CATALOG_NAME = #CatalogName,dbType=NVarChar#); paramObject.Add(CatalogName, master); Mapper.QueryForListIDictionary(DynamicSqlStatement, paramObject); = Currently, this result is a sql exception as the IBaits.NET send the text of __DynamicSql directly to the sql server and so the #CatalogName,dbType=NVarChar# is not a valid sql fragement. I want the IBatis.NET treat the CatalogName as an inline-parameter-map instead of send the original text of __DynamicSql directly to sql server. It's may require the IBatis.NET parse the content of a mapped-statement recursively?
