java sql query on data imported from csv file

Question

I am planning a Java program which is working with data in csv files which I will load into 2D arrays or a hash map or some other object. I am curious if Java has any library or anything that would permit the implementation of SQL statements to query subsets from internally stored data objects.

I am wondering if maybe the JBDC drivers that allow Java to connect with or control relational SQL databases can be applied to internal data objects.

Answer 1

Your best bet would be to use h2 with the inbuilt csv support. You can find more details here http://www.h2database.com/html/tutorial.html#csv . I like this approach since this allows you to query / manipulate the data in a way a jdbc statement allows you to.

Answer 2

还有一个JDBC驱动程序 ，使您可以直接使用SQL查询CSV文件。
