问题
I have a project with a derby database in it.
I want to be able to make a backup or export the database so I can give it with the project files to my lecturer.
回答1:
By default, the database resides in your home folder under .netbeans-derby (this folder may be hidden under Windows). Copying this folder will work, but your lecturer will have to "register" this copied location with his IDE. To do this:
- Under
Services, open theDatabasesnode. - Right-click on
Java DBand select properties. - In the
Database Locationfield, enter the path to the copied folder.

There are lots of ways to backup and/or export data in a Derby database: here's a link to the docs: http://db.apache.org/derby/docs/10.9/adminguide/cadminparttwo.html
In order to make the backup, you have to find the database data on disk. It will all be located in a single folder/directory; that folder/directory is named using the name of your database. So if your database is jdbc:derby:brydb, look for a folder named 'brydb'.

Late, but it may be useful for others:
- In Netbeans, start a connection to your database.
- Right click on it and select 'Execute command'
- Write this:
CALL SYSCS_UTIL.SYSCS_EXPORT_TABLE (null, 'YOURTABLE', 'PATHTODUMPFILE', null, null, null)
Remember to write the name of your table and path between simple quotation marks ' '

For 2017 NetBeans.
Let me suggest how to export sql scripts' file(after connection to db). So that,go to
1. Services -> Data base -> link -> Schema ->tables -> MYDB.
2. Rightclick on MYDB and select 'Browse data'. And then click 'execute sql' first icon/button
3. In the list of rows below rightclick any of them, and choose "Show scenario for Create.." Sometimes output/logs window may overlay that list though. In such case close it please.
4. Copypast(cntrl-c,cntrl-v) instruction from popup window to a prepared by you previously txt file
5. Again click any of bottom list's rows. Select all of them by cntrl-a keys' combination. Rightclick and select "Show scenario for INSERT.."
6. Copy instruction from popup window and past/add them to mentioned above txt file
You are done with sql scripts' file.
