Oracle SQL Developer - Export only constraints - oracle-sqldeveloper

Is it possible to export only constraints with SQL Developer from a table. I right clicked on table that I am interested and clicked on export, but I did not see any option to just export constraints. Wanted to check with the forum, if I am missing something. The version of SQL Developer I am using is 3.2.20.

I found the answer. Hope it helps someone. You can click on the table and then on the right pane click on constraints tab. This will list all the constraints. You can then right click on the list and say export.

Do not see tables in the MySQLWorkBench GUI

I am attaching the image of what I see at opening MySQLWorkBench for a particular connection. Previously, on the left pane I saw the expandable list of the tables, now I see the empty pane.
The change was in the username/password for standard TCP/IP over SSH connection method for connection to AWS RDS.
Is it possible to see the list of the tables again? Maybe I changed accidentally some MySQLWorkBench settings?
I have MySQL Workbench 8.0, version 8.0.19 on my MacBook Pro. Try to hover your mouse in this area shown here (with the red arrow):
Then click, hold, & drag down to reveal the tables:
Go to Edit and open Preferences
Select SQL Editor and check both options under sidebar. Click OK.
Hopefully, it will solve your problem. To answer this question, I took help from here

Truncate table in DBeaver right click menu/GUI

I am trying to find an option to truncate table in the right click menu or somewhere in the GUI of DBeaver. The database is SQL Server.
Is there any other option rather that explicitly writing the truncate script?
In DBeaver 7.2.4 - Right click on a table, that needs to be truncated, choose Tools->Truncate, click 'Start'. That's all.
This feature is not yet available for SQL Server. May be DBeaver will include this in their new versions.

Cannot Add Table (with primary key) to EF Designer

I'm unable to drag a new table onto my entity framework designer. When I drag the table over the designer, the icon of a circle with a line through it shows up and I can't drop the table onto the designer.
From my research, it seems the biggest issue is the table missing a primary key. Well, my table has a primary key.
Another site suggested: "Please remember that your tables should be related to each other instead of isolating themselves from each other." I'm not sure how that makes sense. Some tables just aren't related to others.
Any ideas on what I'm missing?
I think I may have found it. This link states that if the Visual Database Tools DLL gets updated, that could cause the problem. I did indeed just recently install SQL Server Data Tools.
However, instead of trying that fix, I found a decent work-around: I simply right-clicked on the designer and chose Update Model from Database... That worked.
Hope this helps someone else that's having this issue...
