    I have a boolean value want to save to Oracle database. Since Oracle does not support "bit" type, I have to use Number(0,1) and I can't map it to a boolean property in my mapping class. I used int type to map to database and convert it to boolean when I use it in my code.

    Is there a way I can map the boolean property to the Oracle database table directly?

    Thanks in advance.

    Hello Chen,

    You can specify you property as boolean directly. There is no need for you to do some extra casts in your project. 
    Please see the attached sample project, where I have an example for a forward mapped boolean, which is translated to the db type number. Also you can find a reverse project, where I used a number(1) db type that is mapped to a boolean in my domain class. Please adjust the connection string in the app.config to work with the projects.

    I hope this information is useful for you.
    Feel free to ask if you have any other question.
