I would like to edit my question to this:
if we have two tables t1 and t2, both of them have a date variable. t2 have another variable say var2 that we would like to do the following with:
if we compare the dates between t1 & t2 and any matching is found then we would copy the value of var2 corrseponding to that date from t2 and add it to t1. How can we do that?
thaks for giving it a look.
