Hello everyone.
I am using the RPgSQL package, and am having some trouble using the
db.execute command. I successfully connect to my database, and issue a
simple SQL query, like db.execute("Select * from c0000075"), where
c0000075 is a table in my database. But when I try to fetch from the
buffer, R tells me that the table consists of just a null value! Any
suggestions?
The db.execute()-function has a parameter "clear" with default "T"rue, which causes the buffer to be cleared after command execution. Simply set it to "F"alse. (Yes, it's not very intuitive; I ignore the reasons which might have induced the package writer to do this) -d
