Even when I did not use v_status, and assign value 'valid' or 'invalid' to the
output parameter directly, the same error occurred.
Not use v_status where, in the DECLARE block or as an alias in the query?
If it where me and I wanted to keep the variable in the DECLARE block I
would do:
DECLARE
_v_status TEXT;
At least you would be able to track which variable is in play.

An SQL alias for table, column, etc or an alias for a function argument?
