How in H2DB get sql dump like in MySql?

I have H2DB database which stores data in files. I have 3 files: test.18.log.db, test.data.db, and test.index.db.

I want get SQL dump file like when I use mysqldump. Is it possible?

Yes, there are multiple solutions. One is to run the SCRIPT SQL statement:

SCRIPT TO 'fileName'

Another is to use the Script tool:

java org.h2.tools.Script -url <url> -user <user> -password <password>

Then, there are also the RUNSCRIPT statement and RunScript tool.

By the way, you should consider upgrading to a more recent version of H2. With newer versions, the two files .data.db and .index.db are combined in to a .h2.db file.

If you want to get schema and data, you can use

SCRIPT TO 'dump.sql';

If you want to get only schema, you can use

SCRIPT SIMPLE TO 'dump.txt';
