>>>I cannot change the SELECT part of my query (if understand your suggestion correctly). That is, the SELECT part (before FROM) involves many fields. Unless you mean that SELECT TOP 1 can be part of the LEFT JOIN expression.

>As I mentioned to Naomi, I was showing the case simplified. The resulting query can have more than one record (there is another LEFT JOIN that I didn't mention). But if this LEFT JOIN that I mentioned pulls not 1 but 2 records, then the resulting query has double the number of records. You see what I mean?

That's not what you originally asked
