RODBC: Minor problem, I hope.
Sorry for the numerous posts, I found that an old (~ June) post had the same
title and confused me (and the list server) greatly (and made it hard to get
this as a new thread).
Anyway...
I'm trying to get the RODBC package to work with a MS Sql database
(Wonderware's InSQL). I'm able to connect to the database using the

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

RODBC and RDCOM
I got a table on SQL Server, which has columns EquationId (int) and
Formula (varch(900)).
I need to select Formula with certain EquationId, for example,

RODBC odbcCloseAll odbcClose Windows XP
Hello...
After installing the precompiled version of R 2.1.0 (congratulations
to the R Development Core Team) for Windows XP (Service Pack 2), I'm
having problems with the "odbcCloseAll" and "odbcClose" functions
within the "RODBC" package. I get pretty much the same error message
for both functions:

segfault reading large BLOB from SQL Server
I am getting segfaults when I try to read a large binary object from a SQL
Server database via RODBC. I am using the FreeTDS ODBC driver, and it has

relevant parts of the session below.
Each row of the v_MAFiles view holds a text, html or pdf version of a
document. The FileType entry is one of TXT, PDF, or HTML. If

RODBC with Windows XP
Hi R-Users,
I have very recently switched from using R on windows 2000 to windows XP
Professional. With XP I am having problems
using the "odbcConnect("")" command. I can use the command perfectly well
until I close the database channel
with the command "odbcClose(channel)". When I try and re-establish
connection following the close command no dialog box appears

Package RODBC
I have some questions about the RODBC package.
library(RODBC) # required for those who want to repeat these lines
1st, I noticed that the following sequence does not work:
channel <- odbcConnextExcel("test.xls")
tables <- sqlTables(channel)
name1 <- tables[1, "TABLE_NAME"] # this should be the name
plan1 <- sqlFetch(channel, name1) # bang!

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:

Package for converting R datasets into SQL Server (create table and insert statements)?
Hi,
R contains many good datasets which would be valuable in other
platforms as well. My intention is to use R datasets on SQL Server as
a sample tables. Is there a package that would do automatic conversion
from the dataset "schema" into a SQL Server CREATE TABLE statement
(and INSERT INTO statements)?
For example.

Hi,
May be you can try this:

Pred1<- get(obj_name[1])
Actual1<- get(obj_name[2])

dat<-cbind(melt(Pred1,id.vars="S1"),value2=melt(Actual1,id.vars="S1")[,3])? # to reshape to long form
colnames(dat)[3:4]<- c("Predict","Actual")

Comparing two functions
Hi. I am new to R and facing a problem that I cannot solve.
I am writing some basic functions. Then I would like to have a master function that allows me to call one of the functions which I created, but I cannot figure out how to do so.
Below is an example. The functions rnormIra and runifIra both seem to work fine. I do not get an error message when entering the definition of the master

RODBC Seg Fault
Hi Everyone,
At the end of this email is a transcript of a problem I have found in
RODBC version 2.3-1. It appears that the bug fix in odbcClose for the
memory leak has meant that the garbage collector is falling over when it
tries to free up the extPtr attribute of the RODBC connection pointer.
Any advice on how to fix this?
Thanks for your help,
