Description

When I want to load a table from SQL editor from DB Manager nothing happened.
In case where my primary key won't be unique, I make a row number but same problem.
When I execute, everything is well display, everything is fine.
Despite indicate primary key and geometric field, it doesn't work when I press load. Nothing, no error indicated, no loading time.

Tested on QGIS 2.8.2 under Windows 7 64 bits (on 2 computer)
And my openSUSE 13.2 64bits with same version.

I see that plateform and version was delete, what should I indicate in plateforme and plateform version ?
About your question, as it didn't work with primary key "oid" define as constraints, I try to generate a serial field rowid ... but it didn't work.
I've done that many times with 2.4 and it was working without any problem.

we usually use this fields to define if an issue is specific of a certain platform/version.

#4 Updated by Saber Razmjooei over 9 years ago

If it doesn't work in Windows and Linux it is likely to be:
- A problem independant of your platform
- (very likely) to be a problem with your database

I can't reproduce your problem on either platforms with my pg database. Could you provide a screenshot of info tab from your database.

#5 Updated by Giovanni Manghi over 9 years ago

Does this happen only if the query contains a WHEN conditional?

Yes only when conditional.

@Saber

Could you have the screenshot from DB Manager in QGIS like the ones I have attached.

#9 Updated by Giovanni Manghi over 9 years ago

Reinstall 2.4 version, it works :S

does this means that the same query with the same tables works on qgis 2.4?

Could you please post the simplest version of the query that does not work for you?

#10 Updated by Nicolas Rochard over 9 years ago

Yes it able to display in QGIS
In attachment, query as simple as possible and both table display in dbmanager.
Result is clearly displayed as working but no way to load it in QGIS (that detect correctly geometry column)

Did anyone spot a WHEN yet? BTW I find the screenshot not very helpful.

Why not the @CREATE TABLE@s for all tables involved, the query that used to work in 2.4 and the message log output of 2.8 (if any) in plain text (quoted with <pre>...</pre>).

There should be a unique column in the query - like the in the first query (ie. row_number() OVER ()). Not sure why it doesn't work. Is there any message log output after trying to load that as a layer?

#12 Updated by Nicolas Rochard over 9 years ago

Sorry, my fault, I was talking about a WHERE clause and not WHEN.
I send most simply query for example. But if my unique column won't be unique, QGIS display me an error. By the way, I've tested with a row number and same problem.
I'me gonna to reinstall QGIS 2.4 and done what you've asked.
