Using the package /RMySQL/ I have established a connection ('con1') to a MySQL-Database called 'mc'. This database contains a table called 'mc_2000' which has 200000 observations on several variables. One of these variables is called 'B5' (type 'double'). When I generate a numeric vector in R called 'B6' that has the same length as 'B5': How can I replace the values of 'B5' with the values of 'B6'? I tried
dbGetQuery(con1, "UPDATE mc_2000 SET B5 = B6", B6) but this doesn't work. The same applies to: dbGetQuery(con1, "REPLACE mc_2000(B5) VALUES(B6)", B6) Any help would be appreciated very much.
