I assume they are not strings, but rather numbers, therefore you could try:

. tostring id2, replace
. replace id2=subinstr(id2,"0","",.)

If they are strings then you could use only the second line.

Dear Statalisters,

I need to merge two datasets. The problem I have is that one the id
of the master contains zeros (id2) and the other does not (id1). For
example, for
one observation I have: id1 = 718258, and id2 710820050008. My basic
question is: how can I get rid of the zeros of id2 so that I can do a
one-to-one merge using the id variables? Which is the function I need to
use?

Thanks in advance,

Marcos
