[SQL] Sqldf - error message
Hi All!
I just discovered sqldf and im very enthousiastic, as I am a big fan of
R and I often get frustrated using Access for datamanagement.
I tried running some queries from Access in R, and it works very well.
However, I have problems with some queries.
If I run this SQL query:
> sqldf("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_BroedselLocatie.NestkastID =
dbo_tbl_Nestkasten.NestkastID)
+ INNER JOIN dbo_tbl_Terrein ON dbo_tbl_Nestkasten.TerreinNummer =
dbo_tbl_Terrein.TerreinNummer
+ WHERE (((dbo_tbl_Terrein.RingCentraleNaam)='Oosterhout a/d Waal'));")
I get the following message:
Error in sqliteExecStatement(con, statement, bind.data) :
RS-DBI driver: (error in statement: no such column:
dbo_tbl_Broedsels.BroedselID)
( I also tried removing the 'dbo_tbl_' part of the dataframe names, but
still the same problem occurred)
Now ofcoarse I looked on google, because I was sure someone would have
had the same problem.. And yes, I found this website...
http://code.google.com/p/sqldf/
They say:
This happens when you try to use variable with a dot in it (as dots have
special meaning to SQL) or if you try to use SQL92 reserved keywords.
SQLite/RSQLite replaces dots with underscores and changes keywords words
so that they can be used. The keywords in question can be found by
entering the following at the R command line:
.SQL92Keywords
In this list of keywords, i cannot find any word that is close to the
error... So, i was wondering if someone knows how to solve it.
preferably i do not want to change all variable names, as these names
come from the 'big main database' of the institute.
The site also says that SQLite/RSQLite can fix the problem... but then
when i look in their help, i cannot see how i can easily use those
commands...
Anyone?
Kind regards,

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

dbo_tbl_Nestkasten.NestkastID
INNER JOIN
dbo_tbl_Terrein
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.

Re: [SQL] Sqldf - error message
Nothing is wrong with the data... Everything is there in the dataframe. All the
names are case sensitive, but the way it is spelled is correct So that cant
be the problem

Re: [SQL] Sqldf - error message
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.
