[R] RODBC problem
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 that corresponds to your MySQL server version for the right syntax to use near '\t_studi(\004 Please note the funny character at the end of the table name in the error message. The Test Data Source option on the ODBC Data Source Name configuration panel report success. Who can help me here?

Hello, as I wrote I call sqlFetch(channel,t_studie) and this function generates in the background the concrete query. How can I view/log/... the concrete query?

[R] RODBC Problem
Hi All, I'm using Microsoft Office 2007 Beta version and I have one file in .xlsx format with size 168MB. How can I use odbcConnectExcel in this as this function only supports .xls format? I have huge data containing 603470 rows in a .csv file. Thanks in advance. Sumanta Basak.

[R] RODBC problem
In a mdb table, I have a text field with values of 1, 2, When I use rodbc to read it into R, it becomes numeric. Is it a bug or something?

[R] RODBC: problem saving a new table in an Excel database
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 some test code which reproduces the error (assuming that c:\test.xls is a standard blank Excel spreadsheet; i.e. Sheet1, Sheet2, Sheet3) con = odbcConnectExcel(c:\\test.xls) df = data.frame(x = rnorm(10), y = rnorm(10), z = letters[1:10]) sqlSave(con, df) Error in sqlSave(con, df) : [RODBC] ERROR: Could not SQLExecute Where am I going wrong? Thanks, Dave __ [EMAIL PROTECTED] mailing list https://www.stat.math.ethz.ch/mailman/listinfo/r-help

The driver does not support writing to Excel: did you check? On Mon, 21 Jul 2003, David Khabie-Zeitoune wrote: Hi I am using package RODBC version 1.0-1 under R version 1.7.1 on Windows XP Pro.
