Hi list,
I have code which reads data from sql server using RODBC in R version
2.12.1. The code used to be ok, till today when I get the following error.
The data does not have any problem, but if I run the code in differnt pc, it
runs till different number of trial then it fails, for example on one pc, it
runs up to 30 times, other pc up to 66 times, then it fails. Any help
please?

[1] "so far 66 accounts out of 936 have been done!"
Loading required package: RODBC
Failed with error:  ‘subscript out of bounds’
In addition: There were 50 or more warnings (use warnings() to see the first
50)
Error in `[.data.frame`(mydata, , epcol) : undefined columns selected


thanks
Alireza
