Thanks again for your help.

I am wanting my variable to store a character string exactly as the write.csv function would store as a csv text file;

IE: My goal is to store a data frame of this construction;

x1 x2
1  2
3 4

as "X1","X2",1,2,3,4 (the same format as CSV).

I am aware of the file argument, however that is the problem, storing to a physical text file and then importing into the SQL database is a very inefficient way of doing things, especially when I can use RMySQL to send commands directly to the database.

Kind Regards,

Basically I want to convert R variables (dataframes) into CSV format, store them as another R variable (as a properly formatted text string suitable for csv reading) and then send this to one row in a database.
