纯java sqlite库？

Question

I saw Java and SQLite , but what ones are made in pure java and are platform independent? Also which would be the best to start with? I have never used sqlite but I assume it is like mysql. Also do any of them come with a nice command line tool for testing queries?

Answer 1

SQLite is getting quite a lot of hype in other language domains, however with Java you have something else available:

• HyperSQL ( more commonly known as HSQLDB ) is pure Java RDBMS which is specialized around running it as part of your application meaning that you can embed it to your software and it just works.
• H2 is a complete rewrite of HypersonicSQL ( common ancestor for H2 and HyperSQL ) and is also fully Java. One nice feature of this one is RDBMS emulation which allows it to function with SQL written specifically for, say, Oracle RDBMS.
• There's also the almost mandatory Apache Commons variation too, Apache Derby . As with the other two, Derby is also embeddable and has a small JAR file size footprint.

As for tools, well, that varies a lot. Most of the Hypersonic family products for example are mainly meant for unit testing which means that you can unit test your DB Schemas and actual queries quite easily with ( almost ) plain Java code.

Answer 2

sqljet ，它与名称相矛盾，没有SQL，但可以使用SQLlite数据库。

Answer 3

And updated answer, you may want to try Xerial's Sqlite JDBC driver . While its current version is not pure-java, it packages binaries for major operating systems so that it is mostly portable.

Also sqlite4java also currently packages binaries for major OSes.
