If there isn't an index on the EMPID column, create one. Since you're selecting just a few rows, the database should use the index and it should be quite fast.
The query itself is so simple that there isn't much to optimize. However, you should explicitly name columns instead of specifying SELECT *. It won't help much, but (depending on the database, your indexes and network) it might be a bit faster, especially if you select more than just a few rows and/or there is an index containing all columns you're selecting.
