sqlSave writes, but only for sqlFetch
I've been having some issues with sqlSave, and I think I've found an clue
that may identify the problem. In the code at

I connect to a Netezza instance, make a simple table, and query it.
Despite sqlSave succeeding without error, sqlQuery tells me the table
doesn't exist. Also, when I query the database outside of R, I

RODBC: sqlQuery is successful, but a similar sqlFetch returns error
Greetings guRus --
I have successfully queried a large (24,445 rows by 281 cols.) in-house
database using the following RODBC query (without the line breaks)
testout <- sqlQuery(channel, "select idSchedule,EXCL_Total from
dbo.vwC1198_2006_RawData_With_CMPL_EXCL")
This returns a dataframe of 24445 rows and two columns (as intended),
but the following command

Fetching data from MySQL via odbcConnect - Error in as.POSIXlt.character(x, tz, ...) :
Hi!
I am trying to retrieve data from a MySQL Database using RODBC with the
commands odbcConnect and sqlFetch. There are different data files in the
database and in some cases it works without any difficulties. Nevertheless I
get an error with some data files. Since I'm not familiar with MySQL I hope
to get some ideas here.
My code looks as follows:

R crashes when using the RODBC Package
Hi,
I've written some code that fetches data from an Access Database (2003),
processes the data, then saves the modified data back into a table in the
Access database.
It works if I only pass through the code once, but if I put a loop around
the code so that I fetch data from a different source table, and then save
it again to a different destination table, the code crashes. It is

sqlSave, fast=F option, bug?
Hi,
Using the fast=F option, sqlSave saves without matching column names.
It looks like a bug to me..........
Here's a simple (artificial) example.
-----------------------------------------
Create a dataframe and save it to a database table "test" as follows:
df <- data.frame(T=1, S=10)
sqlSave(channel, df, "test", rownames=F)
The table now looks like

RODBC and schemas
I have found that the "schema.table" syntax used in Postgresql (and
Oracle) does not work directly with RODBC.
This works

con<-odbcConnect("mydb")
d<-sqlQuery(con,"select * from meso.trees")
However this does not.
d<-sqlFetch(con,"meso.trees")

colnames argument in sqlFetch backwards? (PR#7355)

Submission from: (NULL) (192.12.78.250)
The TRUE/FALSE options of the colnames argument in sqlFetch (RODBC) seem to be

This may not come as a surprise -- sqlFetch() (and perhaps other ?) appear

was not able to find documentation that specifically mentioned this,
although the Help pages vaguely hinted that there might be difficulty with

sqlFetch doesn't read the whole objects.
Hi everyone,
I connected a data in FileMaker server with odbcConnect.
When I call the data "CANCERS" using sqlFetch, it looks okay.
However, the number of obs was different with the actual number.
If I read the same data from Microsoft Access, there are 656 obs. in it but
srt() shows me 600 obs.
Does anyone know why this happened and how to read all obs. from R?
Thank you in advance.

RODBC to import/export xls files
Dear R users,
I've learned today about RODBC package in order to import xls file to
dataframes and export the dataframes to xls files.
However I have some problems. Please excuse me if these are basic but as
I said, I've just begun with this package.
Also this email is quite long, but everything is related, so I don't
think it would be better to split it. Moreover, there's a
