Hi @sanderlenselink,
It’s been quite a while since I last used MS Access and have currently no access to the application so I had to google it. It seems that since the MSysObjects is a system table it is not accessible for access via SQL or it has to addressed differently.
What you could try mentioned as solutions in my findings for SQL requests:
a) Address the table as sys.MSysObjects or use
b) “SELECT * FROM information_schema.tables”
After downloading an Access sample db I checked both, while a) gave me an error that “SYS” is an invalid schema name, even after setting sysSchema=true in jdbc parameters b) succeeded and provided useful details.
Hope this helps you,
Best,
Michael
