NOT Operator at SAS BASE 9.4

[cons]

Hello everybody.

IS it possible to combine the WHERE and NOT statement with operator IS NULL or IS MISSING?

IN Base 9.2, it isnt. But I did try it and it works. Please help me.

Thanks.

Hello @cons,

Yes, you can combine the NOT operator with the IS NULL or IS MISSING operator in a WHERE statement.

I don't see a difference between the tables of WHERE statement operators for SAS 9.2 and SAS 9.4. There can be no doubt that a combination as in

where not (x is null);

is valid. Even the notation

where x is not null;

works and it is mentioned in the section "Use of Indexes" of the WHERE statement documentation of both SAS 9.2 and 9.4 (see links above).
