Thank so much!

There are only a handful of commands executing in this gist. I'd recommend stepping through each of them manually and then verify that the restore command on line 32 functions. If that works you should have a .sql file. This script is years old and may need updating. We've since migrated to the SaaS platform so I don't have anywhere to test and validate this script anymore. Best of luck recovering your data! Thanks, - Chris

Thank you! I will try again.

hi Team, java -cp /lib/h2-*.jar org.h2.tools.Recover step is creaing a .sql file with table names O_Number instead of actual table names.

INSERT INTO O_87 VALUES(10606544, TIMESTAMP '2022-11-28 13:44:14.143', 1, 'comments ', NULL, 635, 188, NULL);

please let me know how to fix this
