RODBC: sqlSave leave primary key and other columns null
I have an existing table, and I am trying to use sqlSave to append
additional rows to this database. I omit the primary key, which is a
uniqueidentifier type (MS SQL), so that the database can populate that
field. However, I get the following error:
> sqlSave( ch, result, tablename=thetablename, append=TRUE,
rownames=FALSE, colnames=FALSE )

Vignette problem and CRAN policies
Hello, All:
The vignette with the sos package used "upquote.sty", required for R
Journal when it was published in 2009. Current CRAN policy disallows
"upquote.sty", and I've so far not found a way to pass "R CMD check"
with sos without upquote.sty.
I changed sos.Rnw per an email exchange with Prof. Ripley without
solving the problem; see below. The

RODBC sqlSave / append problem (windows XP, R 2.13.2)
Dear All,
Using RODBC I have read in a (429 x 11) dataframe from Access, and would
like to append two columns of transformed data (429 x 2) to the original
table (thereby making it a 429 x 13 table). I would ideally like this to
be the same name etc as the original table in Access.
I have used the following command:

problem with looping on sqlSave()
Dear R users,
I have a follow-up question on sqlSave().
Since most of the output from the tests I use are lists, I would like to
loop to export each element of the list and append it to the sheet.
Here is what I do:

RODBC and datetimes

and redefine the table to incorporate the new column (in the

RODBC, Excel, and data truncation when writing
Hi,
I am hoping to use the RODBC package to write a dataframe to an Excel .xlsx
file. The dataframe contains at least one field with character elements
that exceed 255 bytes, which appears to be the cell width limit in Excel.
Below is example code and the warning message received:

RODBC and 64 bit
Hi all,
I was quite succesfully working with the RODB package on a 32 bit linux
box to connect to a MSSQL Server via the freeTSL driver. After changing
to a 64 bit environment I ran into some segmentation faults using
function sqlUpdate on large database operations (the actual seg faults
occured in the call to the C function ODBCUpdate).
I just briefly looked into the code and found some extensive

.Call and data frames
Hello,
I'm trying to fetch a data frame through the C API,
and have no problem doing this when all columns
are numbers, but when there is a column of
strings I have a problem. On the C-side the
function looks like:
SEXP myfunc(SEXP df),
and it is called with a dataframe from
the R side with:
.Call("myfunc", somedataframe)
On the C side (actually C++ side) I use code

How to use `[` without evaluating the arguments.
Hello R-devel,
I am currently attempting to implement an API similar to data.table wherein single bracket subsetting can accept an unquoted expression to be evaluated in the context of my object.
A simple example from the data.table package looks like this:
DT <- data.table(col1 = c('a', 'b', 'c'), col2 = c('x', 'y', 'z'))

RODBC: follow up
Hi Michael,
Here is the result of my first testing:
(0) Dr. Watson
Sorry, I should have given a more precise description: by default in R
exists a function with the name 'table', if you use this name as in
odbcPrimaryKeys(0, table)
a Dr. Watson occurs, because table does not give a table name.
However, it is always a good idea to prevent Dr. Watsons, even if it is
triggered by a

Problem with ODBC access to SQL database
I have the following problem in getting the "sqlSave" function from the

RODBC under Windows
Hi,
I have been just playing with the ODBC connectivity under Windows. I have
never done this before and I thought I would go through some examples in
the "Data Import/Export" manual and learn how to setup data connections
while doing that. I ran into a small problem and I am not sure if this is
something I am doing wrong or a bug or, perhaps, a feature of the RODBC
package.
