No longer seeing Schemas

[This topic is migrated from our old forums. The original author name has been removed]

When I expand the Schemas tree object I am no longer seeing child objects. If I double click I am presented with this error: *An error occurred while performing the operation:* You probably don't have the required privileges to view/manage this object. Edited by: ekaufman on May 15, 2014 4:42 PM

Re: No longer seeing Schemas
Hi, Which DbVisualizer version are you using and what database and driver? To further reveal what is going on, try enable debug of DbVisualizer in Tools->Debug Windows and then re-connect and perform the operation that fail. Post the debug output here. Regards Roger

Re: No longer seeing Schemas
Hi, Thanks for the log. You need to open the Connection properties and choose the Objects Tree category. Select ALL_ for the System Views Prefix. Press Apply and re-connect. I hope this helps. Regards Roger
