RODBC and Date/Time variables
I do this by having a POSIXct variable in R and using sqlSave in RODBC to write the SQL table. Examples are part of my test suite, so I am sure they do work. It is not at all clear how you are trying to import the data into MySQL.

This is really a query about MySQL which I am trying to use to set up a database which I will then access with RODBC. I have my data in a .csv file, and some of the fields are date/time fields. I tried to create a table using mysql with the definition of the date/time field given by CallDate DATETIME, but I got an error saying that the first row has 28/07/2006 0:00 in that field. What I don't understand is if I open up the .csv file using XEmacs and look at that datum I see 2006-07-28 00:00:00 which mysql should accept as a DATETIME value. If I specify that the field is text with CallDate CHAR(19), then I can create the table without a problem. Then when I issue a query and obtain the value of the field in the first row RODBC gives me 28/07/2006 0:00 which I guess doesn't surprise me. Can anybody offer an explanation, and also can anybody advise how to read the field in as a DATETIME type in MySQL? I have some other date fields too which in XEmacs show as for example 18/01/2007 My understanding is I can't read those into a MySQL table as type DATE. Can anyone offer some advice on that? Some details: Windows XP, R 2.4.1, RODBC 1.1-9, MySQL 5.0.41 Thanks in advance David Scott
