Re: SQL join, limit to one row per employee

Yep S/36 stuff. Did not think it would be that obvious.
doing my best to 'modernize'. I can only do so much.
I really want to get out of this s/36 stuff...

I have an SQL doing an inner join between two tables.
The results have two rows for some employees, due to one table having

two 'active' rows for that employee.

How can I write my SQL to only have one row for that employee?

Whenever you have this situation, you can
- use WITH to construct a testable CTE with the desired cardinality,
desidered row filtering, that you then join to
- or if more idiomatic use a LATERAL (basically with LATERAL you can have
native I/O CHAIN like results... i.e pick the first record etc.).
