Hi DataLab team, 

I was trying to import a table but I get the message 'Error importing MyDB table: relation "mydb" does not exist' on the xmatch service and Jupiter-notebook. On the other hand there is another issue with the decaps_dr1.object table, since the service does not recognize the columns, so I'm not able to select RA and DEC. 

Thank you in advance!

Hi Andrea,

the decaps_dr1.object table now offers .ra and .dec columns in the x-match web tool. Take it for a spin!

Regarding the issue with a mydb table not being available... Can you please post a minimal code sample here, or send us a minimal notebook file (to datalab@noirlab.edu) that shows what you are trying to do, and how it fails? (It would be much easier for us to diagnose it then.)

Thank you!

Hi Robert!
I'm trying to import the table with this line;

print ('Local file result: '   + qc.mydb_import ('e608', 'VVVX_disk/e608_vosa.csv'))

And the error:
Local file result: Error importing MyDB table: relation "mydb.e608" does not exist

Hi Andrea,

I can't seem to reproduce your issue right away. Can you please confirm that VVVX_disk/ is a directory located at the same level as your notebook file? I.e., from the notebook, in a new cell, you should be able to do

!ls VVVX_disk/e608_vosa.csv

Does that work?
Or is the VVVX_disk/ directory maybe on your VOSpace? Then you would have to import like this:


Let us know if this helped. Otherwise, we will dig deeper.
