similar to: Passing dynamic sql statement to RODBC functions

You could construct your SQL statement as a character string using paste() and pass this as an argument to sqlQuery. Maybe something like this will work for you: >data1<-2.5 >sql.statement <- paste("SELECT * FROM somewhere WHERE something=", data1, ";", sep="") >library(RODBC) >channel <- odbcConnect(...) >sqlQuery(channel, query =

Hello, I am new to the RODBC package, but I have looked over the PDF as well as a few websites that go over the SQL language. I can connect to my database fine using >channel<-odbcConnect("Oracle ODBC") # then am prompted to enter my user id and password After that I'd like to use the odbcQuery function and the SQL statement: SELECT * FROM table_name WHERE SAMPLE_YEA LIKE

I am trying to connect to an internal database and use the sqlQuery command to reduce and retrieve data using the following code: channel <-odbcConnect("some_dsn", uid="", pwd="") txt<-'SELECT Date, Region, Price FROM TableXYZ WHERE Type="Domestic"' sqlQuery(channel, cat(txt,"\n"),errors=TRUE,) close(channel) However, I get the

Dear R-SIG-Debian, while trying to query data from an SQLite database through RODBC on Debian testing, R crashes with the following message: library(RODBC) con3 <- odbcConnect("test3") # 'test3' being an ODBC datasource configured with SQLite3 driver, # but the same happens with SQLite driver sqlQuery(con3, "select * from test") # 'test' being any table

Howdy, I'm trying to use R to access Oracle 8i using the RODBC package On Linux Red Hat 7.3. Specs R version 1.51 Driver: Easysoft ODBC - Oracle driver Driver Manager: unixODBC I get the following error when trying to executing RODBC commands. Can anybody give me pointers as to what I'm missing or doing wrong > library(RODBC) > channel <- ("DSNName") >

Dear R users, I am trying to connect R to data that is in a Access Database but I have problem with the construction of queries using special characters. I am using RODBC package. The following is working : > MyQuery<-paste("SELECT first( (DateHeure) ) , avg(NNO3_AT322_OUT_moy) AS Cond FROM Colonne_3 ") > Col3<-sqlQuery(con, query=MyQuery) > Col3

Dear all, I have some problems with importing data from an Access data base via RODBC to R. The data base contains several tables, which all are imported consecutively. One table has a column with column name "NO". If I run the code attached on the bottom of the mail I get no complain, but the column name (name of the respective vector of the data.frame) is "Expr1014" instead

Hi WizaRds, I'm experiencing a problem connecting to an Oracle 10g database via RODBC (I'm getting this on Microsoft XP). The same SQL queries via PL/SQL Developer work just fine, but when I pump the query through sqlQuery in RODBC then I get a data frame back with 0 rows. I cut the query down alternating between PL/SQL and RODBC until I figured that it's some kind of row limit or

Hi everyone, I am desperately looking for a method to interpolate strings within an SQL statement as follows: I get a lot of rows out of a database (in my example POSITION_to_ZIPCODE Database with holds records for German ZIP Code <--> Gauss-Krueger Coordinate System ) and want this to be selected and computed individually row by row as follows: library(RODBC) channel <-

Dear List, Would anyone know how to perform prepared queries with ROBC ? I had a shot with some of the internal (non-exported) functions of the package but ended up with a segfault, so I prefer asking around before experimenting further... Thanks, Laurent

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()

1. Can I avoid having RODBC use so much memory (35 times the data size or more) making a data.frame & then .rda file via. sqlQuery/save? 2. If not, is there some more appropriate way from w/in R to pull large data sets (2-5GB) into .rda files from sql? [R] reducing RODBC odbcQuery memory use?

I have a question for RODBC users out there. I have used the package with good results for some time. However, I have just switched from an OpenLink proprietary driver for MS SQL to the FreeTDS driver (I think it is MS SQL Server 2000 I'm connecting to if it matters). I was/am running them from unixODBC on a Linux Client. I think I have it set up fine since I can use "isql"

I have an MS Access database with one table and one column holding rep(1:10) I use: library(RODBC) channel <- odbcConnect("test") sqlQuery(channel, paste("SELECT col FROM tblTest"), believeNRows=FALSE) and get: 49 50 51 52 53 54 55 56 57 12337 What? The above should, of course, read: 1 2 3 4 5 6 7 8 9 10 I tried the 'odbcQuery' /

I have compiled and linked a 64 bit version of R (R 2.9.2) and the corresponding unix ODBC 64 bit package When issuing a SqlQuery, I get the following error > library(RODBC) > channel <- odbcConnect("OraLSH", <user>, <password>) > sqlQuery(channel,"select sysdate from dual") Error in .Call(C_RODBCFetchRows, attr(channel, "handle_ptr"), max,

I have found that the "schema.table" syntax used in Postgresql (and Oracle) does not work directly with RODBC. This works library(RODBC) con<-odbcConnect("mydb") d<-sqlQuery(con,"select * from meso.trees") However this does not. d<-sqlFetch(con,"meso.trees") Error in odbcTableExists(channel, sqtable) : ?meso.trees?: table not found on channel

Hi, I'm using R-2.8.1 for windows. I wrote a script calls the RODBC package to run sql queries against an oracle database. It runs fine when run from the rconsole and returns a data.frame with a summary for a set of experiments. I want to run this script using the rinterface.RunRFile command in an excel plugin, using the rexcel package. When I run the code from my excel plugin I
