Is there a simple way to do Query By Example in iBATIS? - java

I had hoped this was baked into the most recent release, but if it is, I can't find the docs via a simple Google search. Failing that, I'd prefer a simple library, but I'll settle for a tutorial.
Thanks.

Ibator can help you with this. Let it autogenerate everything, and you'll find by-Example Queries in the SQL Maps, as well as corresponding Java bindings in the DAOs.
Check "Example Class Usage Notes" on http://ibatis.apache.org/docs/tools/ibator/ for more information.

Evernote: Get a list of all edits

I am trying to develop a simple statistics tool to analyse various behaviours of collaborators within an Evernote Notebook using the Evernote Java API.
I need the informations which user edited which note and when.
Even though the documentation is quite good, I am still unable to find the required functionality inside the api.
(TLDR:)
Is there a way to access a list of edits of a evernote note using the API?
I am not bound to using the Java SDK so if there is a way, which is limited to using another language, it would be no problem to switch.
Andreas - Did you look into these methods in the API?
NoteStore.GetNote and NoteStore.getNoteApplicationData
It sounds like this would be a decent place to start at the very least. I cannot say for certain if this will return everything you are looking for though.
I hope this helps!
I'm not exactly sure what you are looking for but NoteStore#listNoteVersions might be the one you want. You can get a list of NoteVersionId and then use another API called NoteStore#getNoteVersion to get metadata to see which note is updated when.
Note that the API is probably only for premium accounts.

What does the createTable for DynamoDB in Java with a column containing a JSON value?

I am attempting to use the Java/JSON examples located at this web page (which describes the introduction of JSON as a native type to DynamoDB). And while I understand the examples presented on the page, there is no place on the page showing how to go about defining the "people" table itself in Java.
I did find this link talking in the area. However, it appears to have been asked and answered PRIOR to the article above introducing the "official" version of the new API. And even reviewing the article didn't give me enough clues to figure it out myself.
BTW, I am NOT able to use the "AWS Toolkit for Eclipse" as must use the results of this in IntelliJ+Scala-Plugin using SBT.
Any guidance on this would be greatly appreciated.

Query SqlJet at Low level

I got the following problem and no idea on how to solve it.
I am using SqlJet to access and manage a small Sqlite DB.
It's amazing the simplicity of this library! But now, I have to execute a complex query which cannot be expressed using the methods provided by the library. On the website, they say
SQLJet does not support SQL queries; there is an API to work with the
database on a lower level
And I was wondering, anybody of you know what is this lower level API to execute SQL queries?
As far as I can tell from my research, there is no support for arbitrary SQL queries in SQLJet. I first thought it was a sqlite wrapper, which it isn't, so there is also no way to use JDBC.
Other than the lookup rows by name and index stuff, the "lower level" API they are talking about on their page, seems just to be direct access to the internal DB representation, as mentioned in this post.
From a quick glance at the JavaDoc and sources, it might be the SqlJetDb.getSchema() and getTable() methods. There is no proper API documentation or Tutorials, there is even a complaint about this in the issue tracker.
Maybe you can describe what you want to do. Either there is a way to do it though the limited interface SQLJet offers, or I'm afraid I can't help.
Its also good idea to contact the developers directly, as it seems there is not much information to be found elsewhere.

Java Jackcess Library Documentation?

I need to read and write some data on .mdb Access file and over the web I found the Jackcess library that that does exactly that.
Unfortunately I could't find any documentation to use that. On the library website there are a couple of examples, but no real documentation. Can anyone tell me if there's some sort of documentation somewhere?
The javadoc is intended to be fairly explanatory. The primary classes would be Database and Table. The library is also heavily unit tested, so you can dig into the unit test code to see many examples. There isn't currently a great "getting started" document. It has been discussed before, but, unfortunately no one has picked up the ball on actually writing it. That said, the help forum is actively monitored.
UPDATE:
There is now a cookbook, which is the beginnings of a more comprehensive user-level documentation.
You can use jackcess-orm that use DAO pattern and POJO with annotations.

Guide for http://www.ch-werner.de/javasqlite java wrapper library for SQlite?

I'm working on a large computer science school project using java and SQlite.
After finding out that the zentus.org wrapper errors on databases with ON DELETE and ON UPDATE clauses set, I have changed to the other wrapper found at http://www.ch-werner.de/javasqlite.
However, I find the documentation lacking somewhat when trying to get an overview on how it works and how to use it, and the function descriptions are very very short, and you have to scan through every function and somewhat guess how they work and what they do. I wasn't able to find any guides on google on how to use it.
My question: Does anyone know a link for a guide or tutorial for the ch-werner.de/javasqlite wrapper, or else can give me a basic code example, or give a quick overview of querying the database and the most used functions, and how to use them?
I would look at the JDBC Tutorial
