I'm working on a very little program and I need to save some data in a database. I've read a lot about JDBC and SQL, and I'm quite sure to know how to query an EXISTING database. My problem is that I need my java program to create this database in run time... Any suggestions? Thanks a lot..

Using the executeUpdate() method send DML statements to the database.

I really don't get it...shouldn't I be sending DDLs instead of DMLs to create the database in runtime? Could you be a little bit more specific? Perhaps some code would clear this out for me. Thanks a bunch

Don't know if this is even possible. Since a connection object needs an existing database to connect to, you can't use a connection if it doesn't exist. So although you may be able to make some sort of system call outside java, there is no way using jdbc. Another solution would be to use text files (like random access files ). "I'm working on a very little program and I need to save some data in a database. " This leads me to believe that the scope is relatively small and that using textfiles might be sufficient. Jamie

You are correct Jamie. It's not possible as far as I know. Harold, are you actually trying to create a table instead of a database? Doing the former is definitely possible at runtime.

Thank you all for your posts! I think I'm going to use some other data structure designed in a class, and serialize objects, or as you (Jaime) say, using a simple text file. But I guess a serialized object representing what I want to save in some data structure would work as well. I will be saving about 700 records in this text file or object (which would contain a list of records). But would be very nice to have the advantages of relational databases... Once again, thanks a lot!!!

Bosun, out of curiosity, how would you create a table in runtime? -Harold

Harold, you just need to execute a create table statement. "CREATE TABLE yourTableName (columnName dataType, ....) You also need to use the createStatement..... Statement statement = connection.createStatement();
