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&quo...

Hi everyone, I connected a data in FileMaker server with odbcConnect. When I call the data "CANCERS" using sqlFetch, it looks okay. However, the number of obs was different with the actual number. If I read the same data from Microsoft Access, there are 656 obs. in it but srt() shows me 600 obs. Does anyone know why this happened and how to read all obs. from R? Thank you in advance.

...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() doesn't accept the name noms[i]. Neither paste(noms[1], sep = ""). Any suggestion for workaround? Thanks in advance Juli -- Juli G. Pausas Centro de Estudios Ambientales del Mediterraneo (CEAM) C/ C.R. Darwin 14, Parc Tecnolog...

Dear R-list, I am trying to import (all) frames from a Microsoft Access database as individual data frames in a fancy loop, but I'm having troubles figuring out how to use the 'sqlFetch' from the RODBS package in a loop (mostly because I can't figure out how to loop over elements (I came from stata) I would very much appreciate if anyone on the list could help me solve this problem, as it is an issue of connecting to a database I can't really make a working example, p...

Dear all, I successfully set up a local MySQL-database. Connecting via RODBC is not problem, the same in fetching 3 of 4 tables. But trying to connect to table 4 fails. > author<-sqlFetch(test,"author") Error in fromchar(unclass(x)) : character string is not in a standard unambiguous format In principle I understand that error message, but I don't know any solution.

This is about R 2.7.0 and related packages on windows NT. I have a mixture of numeric and character data and empty cells in an Excel spreadsheet with several tabs that I'm trying to read with sqlFetch from RODBC. The data that is returned by sqlFetch is unfortunately not identical to the source data in that in columns with character values in the first few rows the subsequent rows of that column which are filled with numeric values are not returned properly but set to <NA>. Specifing as.is...

R 2.0.0 patched under win2000. MS Office Excel 2003. ODBC Drivers? This may not come as a surprise -- sqlFetch() (and perhaps other ?) appear not to handle table/worksheet names with spaces in them in Excel tables. I was not able to find documentation that specifically mentioned this, although the Help pages vaguely hinted that there might be difficulty with Excel's "peculiar handling" of tabl...

Dear all, I've used RODBC a lot to read in files created in MS excel and access but found a strange problem today: a variable in my data file contained both numbers and text; sqlFetch would set text within a row of numbers to NA; but if first 5 or 6 rows would be text then all numbers would be read in as NA. con<-odbcConnectExcel("xample.xls") #the file is attached or at http://psych.ut.ee/~nek/ajutine/xample.xls sqlFetch(con, "TT$") # ID_NO Setting...

...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 with 13 or more characters do not sqlFetch(channel2, 'abcdefghijklm') Fehler in odbcTableExists(channel, sqtable) : ?abcdefghijklm?: table not found on channel I do not have any tables with 12 character names, to check where exactly the bor...

...bL<http://pastebin.com/W6UGKep9>, I connect to a Netezza instance, make a simple table, and query it. Despite sqlSave succeeding without error, sqlQuery tells me the table doesn't exist. Also, when I query the database outside of R, I see that the table doesn't exist. However, using sqlFetch works, and (perhaps, as expected) the table is dropped upon evaluating close(myConn). Also, sqlDrop works as expected. Thanks for your time. Any thoughts are appreciated. Dave Mitchell [[alternative HTML version deleted]]

R users, Hello, I used sqlFetch to import a data table from MS Access 2007 and I set as.is = TRUE to prevent character vectors from becoming factors. However, I can't figure out how to prevent the $ operator from being added by sqlFetch to the end of each character vector(e.g. TD$ and SITE$). This causes subsequent parts of...

I have probably an old question. I have R.3.0.1 installed in 64 bit windows 7. The odbcConnectExcel in RODBC library does not work. Tried odbcConnectExcel2007 still does not work. Any ideas.

I'm using the RODBC library to read in an Excel file using the odbcConnectExcel function. I can read the Excel data prefectly, however all my character variables get converted to factors when using my.data <- as.data.frame(sqlFetch(channel, "Sheet1")) I've tried using my.data <- as.data.frame(I(sqlFetch(channel, "Sheet1"))) but this creates just one column of data. Is there an efficient way to read in the character variables from my Excel data as characters rather than converting them...
