[postgis-users] RE : QGis 2.0 Copy/Paste from shapefile to Postgis issue if the primary key is a string

[F T]

Hi,

QGis should not deal with Postgre SQl explicit primary keys.

It is postgreSQL to manage the explicit primary key.

With Qgis 1.7.4, copy/paste with explicit primary keys where ok

If QGis 1.7.4 sends a unique primary key, PostgreSQL accept it, if the
explicit key is not unique, it reject it.

QGis 2.0 brings a regression, it put all the primary keys to null...

Denis 's workaround to add a serial to the table and a constraint
(unique not null) to the explicit primary key is not a solution for
us.

We have a lots of tables that are used not only with QGis...

Changing all the tables just because QGis 2.0  needs a non-standard
feature is a pain.

And QGis 1.7.4 was doing this copy/paste job fine.

However, this is a QGis 2.0 pb and not a postgis pb.

I will continue on the QGis List

Thanks

Fabrice

Hi,

QGIS prevent to overwrite the primary key field when it copies/pastes,
this is why it leaves the field empty.
One way would be to add the constraint after the copy/paste if it's for
a single shot.
Otherwise, just add a unique constraint on f1 and add a serial as
primary key.

Cheers,

Denis
