database:

# plesk db dump psa > /root/psa_dump.sql

Find records in the table
psa.ServiceInstallations
:

# plesk db -e “SELECT * FROM ServiceInstallations”
+—-+—————–+——–+—————+
| id | name            | status | serviceNodeId |
+—-+—————–+——–+—————+
|  1 | PleskDns        |    1   |        1      |
|  2 | PleskFileSystem |    1   |        1      |
+—-+—————–+——–+—————+


Find 
id
of the domain
example.com
.

# plesk db “SELECT s.id, d.name FROM Subscriptions AS s LEFT JOIN domains AS d ON s.object_id=d.id WHERE d.name=’example.com'”
+—-+—————–+
| id |       name      |
+—-+—————–+
