Question

I am importing a table from an Access database into SAS where the sequence column became corrupted. I need to create a new sequence column in SAS. I don’t want to re-create the sequence number in Access, as the source tables are replenished on a regular schedule. Is there something like an autonumber column that one can add to SAS?

Answer 1

When you read in a data set in SAS, _n_ refers to the observation number. This should work for you:

data new;
 set old;
 seqno = _n_;
run;
