[gdal-dev] ogrinfo on JOINed layer empty

[William Kyngesburye]

While testing some connections for a Mapserver map file, I'm finding  
that ogrinfo is not showing any info (layers, fields, features) on  
JOINed layers.

A connection that works in Mapserver:

CONNECTION "/"
DATA "SELECT * FROM some_shapefile LEFT JOIN  
'MYSQL:some_database 
,host=localhost,user=some_user,tables=some_table'.some_table ON  
some_shapefile.id = some_table.id"

but in ogrinfo (on the Mapserver computer, so it's still local):

ogrinfo -al -so . "SELECT * FROM some_shapefile LEFT JOIN  
'MYSQL:some_database 
,host=localhost,user=some_user,tables=some_table'.some_table ON  
some_shapefile.id = some_table.id"
INFO: Open of `.'
       using driver `ESRI Shapefile' successful.

It does not show any of the fields from the shapefile or the JOINed  
MySQL table.  I get exactly the same output on a bad JOIN (or other  
non-existent shapefile layer).

CPL_DEBUG=ON doesn't show any helpful debug messages, just (there are  
5 shapefiles in the folder):

OGR: GetLayerCount() = 5


Any hints on how to get ogrinfo to show JOINed layer info?  I think  
I've seen this work in the past.


GDAL 1.5.1, OSX, Mapserver 5.0.2.

Theory of the Universe

There is a theory which states that if ever anyone discovers exactly  
what the universe is for and why it is here, it will instantly  
disappear and be replaced by something even more bizarrely  
inexplicable.  There is another theory which states that this has  
already happened.
