RODBC package -- sqlQuery(channel,.....,nullstring=0) stillgives NA's
There is something strange in R behaviour (perhaps). I have run the same select in Oracle SQL*Plus (version 10.1.0.2.0) and the output comes out with NULLs (which is what it ougth to be). But in R I still get the same result with NAs (no matter I use na.strings or nullstring arguments) An output example follows below: Using na.string="0" and nullstring="0" (sorry by the

R-help, I'm using the RODBC package to retrieve data froma ODBC database which contain NA's.

RODBC and NULL values
Dear All, Writing sooner than I thought I'd need to. I'm using R 2.4 on Mac OS X, with RODBC, PostgreSQL 8.1 and Actual's ODBC driver. I have all my data in Filemaker 8.5, but it is automatically exported into PostgreSQL for analysis as Filemaker's ODBC and JDBC access is awful, slow and has a tendency to crash. I have disability data where for each patient there is a survival

RODBC repeated rows problem
Hello everyone! I'm having the dreaded repeated rows problem in RODBC. Specifically, when I have a NULL value in a column, odbcFetchRows reads the value not as NULL or NA but as the most recent non-NULL value in the column. If there is no such non-NULL column, odbcFetchRows reads the value as 0. Let me give you an example (though you won't be able to run it with the "product"

quoting a table name due to a special character in sqlQuery (RODBC)
Dear List, I have a problem with RODBC on a Paradox-DB, sqlQuery, and special characters in table names. Unfortunately, some of the latter include the underscore <_>. And I am not able to change them. That's not a problem, when I quote the table name: > sqlQuery(channel2, 'SELECT * FROM "anmeldung-alt"') Btw, if I swap ' and " it does not work: >

subqueries in sqlQuery function (package RODBC)
Hi R users. sorry for missing example and if question is to general but I am wondering if it is possible to execute subqueries in function sqlQuery (package RODBC) with opened connection with Excel or SQL server 2000. I couldn't find any example of this. And if it is possible what should be a correct syntax for this query: SELECT ct,COUNT(*) as n FROM (SELECT COUNT(*) AS ct FROM children

RODBC sqlQuery insert slow
Large for loops are slow. Try to avoid them using apply, sapply, etc. I've made the paste statements a lot shorter by using collapse. See ?paste for more info.

RODBC Excel sqlQuery insert into
I have searched the archives for using insert into to update spreadsheets using RODBC and have come up short. So, first off, is it possible? I have put together a dummy xls table (c:\foo.xls)for exploring possibilities of RODBC. Ultimately, I am interested in replacing much of our previous use of vba macros with R ( I'd prefer elimination, but will take what I can get ). In order to
