It looks to me like sqldf is unaware of the rules about identifier
case-folding in Postgres. That column would come back named
"broedselid", but it's probably looking for "BroedselID".
Or possibly it's expecting the qualifier "dbo_tbl_Broedsels."
to be included in the returned column name. Either way, you
need to bug sqldf's authors to fix it.

I thing, you have a problem with data. Probably some creating script
was broken or some similar. The message is clean. Your database has
not column BroedselID. Recheck your query, please. Im not sure - maybe
SQLite identifiers are case sensitive. Maybe are defined as case
sensitive.

p.s. Your style is strange. Don't use useless parentheses
SELECT dbo_tbl_Terrein.RingCentraleNaam, dbo_tbl_Broedsels.BroedselID FROM dbo_tbl_BroedselLocatie INNER
JOIN dbo_tbl_Broedsels ON dbo_tbl_BroedselLocatie.BroedselID =
dbo_tbl_Broedsels.BroedselID INNER JOIN dbo_tbl_Nestkasten ON

dbo_tbl_Nestkasten.TerreinNummer=dbo_tbl_Terrein.TerreinNummer WHERE dbo_tbl_Terrein.RingCentraleNaam ='Oosterhout a/d
Waal'
Query is same and little bit more readable.

Nothing is wrong with the data... Everything is there in the dataframe. All the names are case sensitive, but the way
itis spelled is correct.... So that cant be the problem

I think you (or I) might misunderstand TL's comment. The sql is
probably being sent by some late-in-the-client-side-game driver with
names quoted with double-quote marks, but the database does not have the
column names etc in mixed case. Can you connect directly to the
postgres server (psql -h dbservername -U dbusername) to see the
definition of the tables in question (\d dbtablename)?

It is more complicated than that see:
http://code.google.com/p/sqldf/
It is a framework sqldf over a framework rsqlite over sqlite. The data frames
the OP is talking about are variables that are coerced to being 'tables'. I can
see no mailing list for sqldf itself. The closet I could come is
https://stat.ethz.ch/mailman/listinfo/r-help
which seems to have quite a few discussions on sqldf and would probably be the
better place to ask this question.

Luc,
You need to contact Gabor Grothendieck (cc'd) about this issue. He is
the package author. I'm sure he will be happy to help.
