[R] sqlSave with underscores in table fieldname

[Hoeven, Maarten van der]

Don't understand... What patch do you expect from me? And, I thought my analysis is quite reproducable and thorough. It is im my situation, though.

I'm not patching something, or writing/issueing R-code. I'm 'just' an R-user with a problem/question. 

In short: using underscores in SQL-tablefields  doesnt work, not using underscores in SQL-tablefields does work. See below. 

Question: is my observation correct, that RODBC cannot handle underscores in Mysql-tablefield? If not correct, what is the solution I need to apply?


Thanks,
Maarten
