I have an issue with the merge options. I want to force the merge to
take the match variable from the master file since it is not an
unique identifier in the using file. In other words, I want to all
all observations that have the same hqduns as those in the master
file. But the option uniqmaster gives me the comment below as if I
never even attached the option. And the output shows that it did not
merge anything from the using file. Any suggestions?
I have up-to-date stata 10.
. merge hqduns using sm_NETS, uniqmaster
variable hqduns does not uniquely identify observations in sm_NETS.dta
===================================================================
The message
variable hqduns does not uniquely identify observations in
sm_NETS.dta
is not an error message, but just informs you about the fact which may
be of interest.
If the -merge- did not happen, there must be other reasons - I will
refrain from guesswork.
Hope this helps
