Hi Mariano
I may be wrong, but I don't think that this issue is not related, I have first
checked that reading my data with squeakdbx is ok.
After searching a bit I think that the problem is in Glorp in
DBXPlatform>>createDataTypesMap
"Creates and returns a map that maps Smalltalk classes to SQL datatypes.
The 16r means it is hexadecimal."
^Dictionary new
...
at: 16rFF put: (DBXTypeNotSupported type: #UNKNOWN);
Perhaps a solution would be I think it should be something like
at: 16rFF put: (DBXTypeNotSupported type: UndefinedObject);
with a fromDbxString method defined in UndefinedObject.
fromDbxString: aString
^ convert the string to the true column datatype
The problem here is that there should be a conversion from the string to the
column datatype and the column datatype is unknown here...
I don't know either if it is possible to get it from squeakdbx at this point
(while fetching data) ?

Hi
I 'm writing a small app with pharo +seaside + glorp + squeakdbx + sqlite
and I have a problem reading null values from my database.
Hi Alain. Do you know exactly which query is being sent? Do you think it
can be related to this: http://code.google.com/p/dbxtalk/issues/detail?id=10 ?
It seems that glorp stores a DbxTypeNotSupported in the column description
for null values when the first row has a null value (the column datatype is
varchar).
Any workaround or advice is welcome before I dig into Glorp code
TIA
