coalesce (per.KNOWN_AS,per.FIRST_FORNAME) FNAME,

Hi guys,

coalesce (per.KNOWN_AS,per.FIRST_FORNAME) FNAME,

Open in new window

I was expecting the above to:

- Use the known_as name if there is a known as name
- Use the FIRST_FORNAME if there is no KNOWN_AS name


The known_as name is populated if its there, although the FORENAME isnt being populated if there is no KNOWNAS name, despite FORENAME being avaiable.

Why is this?

Can you provide some sample data?

COALESCE works with NULLs, if the value of KNOWN_AS is not NULL (if it contains spaces), then it will be used.

If the field does contain spaces, just trim it:
coalesce (trim(per.KNOWN_AS),per.FIRST_FORNAME) FNAME,
