Open https://bugs.documentfoundation.org/attachment.cgi?id=153015 Open the query "View_Bericht_Ware_gruppiert" for editing in SQL. Copy the code. Go to Tables → Create View Switch the design-view off and insert the code. Save the view "Bericht_Ware_gruppiert". Close the editor for creating a view. The view doesn't appear in the list of tables. Go to View → Refresh Tables. The view appears. This bug only appears with internal Firebird, not with internal HSQLDB. Tested with LO 6.3.0.2 on OpenSUSE 15, 64bit rpm Linux.
I imagine that this is a duplicate in effect of bug 126580, at least insofar as the lack of display of the newly created View is concerned. Confirming anyway, as I can reproduce this in Version: 6.2.4.2 Build ID: 2412653d852ce75f65fbfa83fb7e7b669a126d64 CPU threads: 4; OS: Mac OS X 10.14.5; UI render: default; VCL: osx; Locale: fr-FR (fr_FR.UTF-8); UI-Language: en-US Calc: threaded
