sqsSave() test using Test.R script returning error suggesting no values upon "insert"
Hi. I attempted to use RODBC and decided to execute all the tests provided in "Test.r" under the unpacked package RODBC folder.

RODBC & MS SQL Server: repeated calls to sqlGetResults() problem
Dear list, RODBC is mostly working very well on Windows XP talking to MS SQL Server. However, when trying to retrieve a result set in repeated batches the first batch returns results ok, but then subsequent calls return no data (see code below). I tried setting believeNRows=FALSE both in odbcConnect() and in sqlGetResults() but this doesn't appear to make any difference. Also odbcFetchRows()

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 ) Error in odbcUpdate(channel, query, mydata,

.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 like this:

RODBC sqlSave / append problem (windows XP, R 2.13.2)

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')) DT[col1 ==

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: library(RODBC) d <-

sqlSave reports invalid regular expression '[^[:alnum]_]+' (PR#7704)
Do not use R-bugs for reports on compatibility of obselete versiond of packages with unreleased versions of R! You did not give the RODBC version no. The current version, 1.1-3, is compatible with R-devel. 1.1-2 was not (alongside a dozen or so CRAN packages). The only bugs here are in the report.

problem with looping on sqlSave()

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
