string - SELECT statement from two dataframes using RMySQL -
consider 2 data frames, dataframe1
, dataframe2
:
dataframe1
has n columns(colmn1, ..., colmnn)
dataframe2
has 3 columns(col1, col2, col3)
can write statement like:
select colmn1, colmn2, ..., colmnn, col1, col2 dataframe1, dataframe2
using rmysql
?
maybe want package sqldf
instead.
try this:
library("sqldf") sqldf("select colmn1, colmn2, ..., colmnn, col1, col2 dataframe1, dataframe2")
of course must replace ...
actual column names.
