I am looking for a Java source code that implements some of the functionalities that exist in SQL, for example some basic table operations (joins etc.). This Java program should ideally be command line based. Note, there should not be any JDBC stuff; the program does not have to interact with an ORACLE database. I'm just looking for an implementation of (a part of) the SQL syntax in Java. Does anybody know if such an application exist and if it is available? - Thanks a lot!
