I thought I did (in the snippet).
I realize now you also would like to see the SQL.
=============
SELECT IMG_PHOTO
FROM CASE_PHOTOS
WHERE PHOTO_ID = :PHOTO_ID -- Key field

Then ,if I may, I would suggest some changes to the help file and FAQ
to enforce that.

The way I understood my reading of those, if you only need a single
row returning a TIB_DSQL is the leanest way to do that. I believe I
read that a TIB_Cursor employs several TIB_DSQL components internally.
I do not recall reading that a TIB_DSQL component should not be used
for a single row select statement.

The current code (as per snippet) is working fine; but I take it that
you recommend changing to a TIB_Cursor anyway.

At least you know I try to do the research first<s>.
