Label:Fmdb is a well-packaged Sqllite class library. The curd of the data can be achieved by simply writing the SQL statement when the project is called. I've tried it. Even handwritten SQL statements are cumbersome, requiring a field to be put together and error-prone. Is there a way to get a field dynamically? Of course there is. In. NET there is a method that gets the name and type of each field in a class. Similarly, I think OC will certainly exist, so the powerful

There are a number of discussions on the web that can be used to delete data files from the Oracle runtime, and for files deleted using the RM operating system command, you can recover files with the copy file descriptor, although the database is still running.However, when the DB is still running, copy the file descriptor directly to recover the file, there are several problems with the operation: Additional storage space required during cop

This article focuses on the runtime mechanisms that are primarily involved in OC development:Run-time work:Runtime work in OC: The design pattern of the OC language determines that the program can be postponed from compile and link to runtime whenever possible. Whenever possible, OC always uses a dynamic approach to solve the problem. This means that the OC language requires not only a compiler, but also a
