Hi, Does anyone know how to pass dynamic sql statement to RODBC function "odbcQuery()" or "sqlQuery()"? eg.: under R session, I did: >library(RODBC) >channel<-odbcConnect(...) >data1<-2.5 >data2<-5.0 I want to construct the INSERT sql statement using variables "data1" and "data2" and pass this statement to odbcQuery() . Can I do this?

Dear r-helpers! I have trouble reading data from an Oracle data base using RODBC Version 1.0-3, R Version 1.7.1, Windows XP, Oracle8 ODBC Driver Version 8.1.6.4.0: > library(RODBC) > channel <- odbcConnect(dsn="PAV32", case="oracle", believeNRows=FALSE) > # ok, this was succesful > x <- sqlTables(channel) > x[37, ] TABLE_CAT TABLE_SCHEM TABLE_NAME

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!

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

Dear all, I'm trying to connect to an MSAccess database (ArcGIS personal geodatabase). I keep getting an error about the channel when using sqlQuery(). However, sqlTables() does not complain about the channel and lists all tables in the database. If I try sqlFetch(), then R crashes. I'm happy to hear suggestions on how to solve this. Best regards, Thierry > MDB <-

Hi List, I used to access a Paradox database using RODBC, but since last week I am not able anymore to fetch any table which has a name longer than 11 or 12 characters. Here is the the pattern of my code, nothing spectacular: library(RODBC) channel2<-odbcDriverConnect('DSN=xxx') #table names with up to 11 characters still work sqlFetch(channel2, 'abcdefghijk') #table names

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 =

Full_Name: Michael Hecht Version: 1.7.1 OS: WinNT Submission from: (NULL) (193.158.76.205) I've got a problem with the RODBC library while trying to access to an MS-Excel file. The Excel file was originally exportet by a commercial software, so I cannot influence it. The problem is, that the names of the tables include spaces, e.g. "Scan 1","Scan 2" etc. If I use RODBC, I

Hello, I use a RODBC connection to a MySQL server on a Debian machine. The call to odbcConnect() seems to be ok, but the result of the first sqlFetch(channel,"t_studie") retrieves this data frame: [1] "[RODBC] ERROR: Could not SQLExecDirect" [2] "42000 1064 [MySQL][ODBC 3.51 Driver][mysqld-5.0.22-Debian_1bpo1-log]You have an error in your SQL syntax; check the manual

Short of uploading a SQL server database, I don't think I can make this example reproducible, but I hope it's not so complicated as to require reproducibility.... I'm using RODBC to get data from Microsoft SQL Server. I can call a parametrized stored procedure without a problem and the proc does indeed execute successfully. However, even though the proc returns the results I found

Calling function "sqlFetch" in library(RODBC) and specifying a character string as 2nd argument, I get an error I don't understand: library(RODBC) channel <- odbcConnect("mydatabase.mdb", case="msaccess") sqlFetch(channel, "mytable") # this works fine tabname <- "mytable"; sqlFetch(channel, tabname) # this gives an error: # Error in

Hi I know that it is very easy to import data from a dbf file to R, by saving the data as csv, for instance. However, I have several hundreds of files to do that. So, I thought of using RODBC to read the dbf files and save it as data.frame. However, I cannot even start (this is my first time using such package): > library(RODBC) > bdades <- odbcConnect("prova.DBF") Warning

A disturbing behaviour of R: an import of data using RODBC library (Windows 98, R 1.1.1) recognizes accented characters in variables names but these can't be manipulated further. See below: > library(Rodbc) > ch<-odbcConnect("Paradox Files") > pollut<-sqlFetch(ch,Pollutio) > pollut Mortalit? Densit? Pollution 1 82 600 110 2 97 960

I'm thoroughly stumped. I've been playing with RODBC and wanted to see if I could retrieve data from text files using this package as well (for the most part, this is an intellectual exercise, but occasionally I do get data files large enough in CSV format RODBC could be helpful) . I set up a DNS called "Text Files" and then ran the following code in R > library(RODBC)

Hello, I am trying to play with RODBC library and Excel Files. In my file (doubs.xls) there are 2 spreadsheets: > library(RODBC) > connection<-odbcConnect("Excel Files") > sqlTables(connection) TABLE_CAT TABLE_SCHEM TABLE_NAME TABLE_TYPE REMARKS 1 F:\\Th?se\\R\\Doubs NA Faune$ SYSTEM TABLE NA 2 F:\\Th?se\\R\\Doubs NA Milieu$

Dear list - I am having a problem using RODBC to access records from tables in a PostgreSQL database. There is no problem establishing the connection using chnl <- odbcConnect (dsn= ... etc. The DSN seems to be properly set up using the PostgreSQL Unicode ODBC driver, and sqlTables(chnl) works OK and produces a list of tables in the database (they are all in a schema called 'source').

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

Hello, i would like import Data from Sybase DataBase to R-1.5.0 via RODBC. With this i get a connection without problems ! channel <- odbcConnect("ODBCName","LoginName","LoginPass") dataSybase <- sqlFetch(channel,"EPORT_XYZ") ,but when i try this i get a message error ? (Perhaps the _ is a problem, i know that's i.e. not usual to name

Hi, Thanks for showing me how to use RODBC and odbcConnect. Now works nicely. The question I've got now is: noms <- list.files(pattern=".DBF") # removing extension names: noms <- sapply(noms, function(x) as.character(strsplit(x,".DBF")) , USE.NAMES=F) for (i in 1:length(noms)) { s <- sqlFetch(bdades, noms[i]) # etc. } But it seems that sqlFetch()
