I have a Postgres database that I am connecting to with the Postgres ODBC driver on Windows XP in R 2.1.0. In the database is a database with two schemas (public and X). With RODBC (1.1-4) , I can connect to the database and get the tables with sqlTables(db). I can query tables in the schema with sqlQuery("SELECT * FROM X.test"). However, I can't get the columns in table X.test

Hello, I am trying to play with RODBC library and Excel Files.

Hi, I am running the RODBC examples form the help guide.

All, I am new in R. I found sqlSave() doesn't work for our Oracle9i. The following was the message: > sqlSave(channel, USArrests, rownames="state") Error in sqlColumns(channel, tablename) : USArrests : table not found on channel Check case parameter in odbcConnect > sqlQuery() works OK. Please help. Thanks. -MY

Hola Javier, si no estoy entendiendo mal, lo q deseo hacer no se trata de configurar los parametros SQL, sino solo de colocar un vector en el argumento VarTypes de la funcion sqlSave. El manual especifica esa opcion, pero no da ningun ejemplo de como usarla. *varTypes an optional named character vector giving the DBMSs datatypes to be used for* *some (or all) of the columns if a table is to be

I can create a temp table with MySQL and R DBI[1], but I don't see how to do the same with Microsoft SQL 2005 and RODBC. R 2.8.1 creates the table, but then it can never see it. I'm looking to avoid replacing the convenience functions like sqlSave(). [1] https://stat.ethz.ch/pipermail/r-help/2009-March/190033.html > library(RODBC) > channel <-

Dear all, I'm working with R 1.2.2 on win98 (256Mb RAM) with ESS 5.1.18. It happens that the start-up is very slow. I don't know exactly how to measure, but with a simple watch I recorded 15 seconds, while the startup of S+ 2000 (Sqpe+4 under ESS) takes around 3 seconds. Tha fact is that sometimes it takes almost a minute (58.30 sec recorded) for the prompt to appear! And ESS gives me an

Dear R users, I've learned today about RODBC package in order to import xls file to dataframes and export the dataframes to xls files. However I have some problems. Please excuse me if these are basic but as I said, I've just begun with this package. Also this email is quite long, but everything is related, so I don't think it would be better to split it. Moreover, there's a

Is there a way to get a table in a certain schema? The Oracle database I am using has a table by the same name in two different schemas. This creates problems in sqlUpdate because to sqlUpdate there are duplicate columns. The following is part of the output of sqlColumns: sqlColumns(eids, "TEST_ARTCL_INST")[,1:4] TABLE_CAT TABLE_SCHEM TABLE_NAME COLUMN_NAME 1

Hi, I have been just playing with the ODBC connectivity under Windows. I have never done this before and I thought I would go through some examples in the "Data Import/Export" manual and learn how to setup data connections while doing that. I ran into a small problem and I am not sure if this is something I am doing wrong or a bug or, perhaps, a feature of the RODBC package. Here is

Hi all, I am currently trying to read, write and append data between R and MS access using the RODBC library functions. I have no problems reading in the data but when using sqlSave and sqlAppend it doesn't seem to work. I have made sure that all the column names are sensible and there are no gaps etc in the variables. My call looks like this: sqlSave(channel,treatlist,test=F) I've

Hi, I've got a problem with RODBC and saving (sqlSave) of a dataframe in Access. R 2.0.1 is running on windows XP. When executing the examples in R help for the "USArrests" data set "sqlSAve" works fine, but running sqlSave() for a dataframe "Adat" > str(Adat) `data.frame': 1202 obs. of 18 variables: containing 18 columns and ca. 1200 rows fails.

Hi, I noticed that if a column is named "end" in a data frame (table.df below), it leads to errors when trying to sqlSave()'it to a postgresql connection: ---<---------------cut here---------------start-------------->--- con <- odbcConnect("PostgreSQL-DB", uid="user", pwd="password", case="postgresql") R>

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

I'm changing some functions from storing data in SQLite (using RSQLite) to storing it in PostgreSQL (using RODBC). When trying to store very long character fields I get the following message: > sqlSave(pg, Grids, rownames = FALSE, append = TRUE) Warning messages: 1: In odbcUpdate(channel, query, mydata, paramdata, test = test, verbose = verbose, : character data truncated in column

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

Hi I am using package RODBC version 1.0-1 under R version 1.7.1 on Windows XP Pro. I am having problems writing a new table to an (Excel) database using sqlSave. I connect to an empty Excel spreadsheet using odbcConnectExcel (which, I believe, uses the Microsoft Excel Driver DSN). Then I try and save a new table to the database(spreadsheet) using SqlSave, but obtain an error message. Below is

Hi, i get error after using a data.frame with subset for "sqlSave". What can i do ?

Dear list, Being new to both the postgres database, ODBC and the RODBC interface, I am somewhat confused by some of the problems I am experiencing trying to connect R to the database.
