You can avoid that the optimizer choose a INDEX by adding/concatenating a
value

examples :

if ID is datatype INT / etc..

SELECT
*
FROM
TableX
WHERE
ID + 0 = 5


if ID is datatype VARCHAR / etc..

SELECT
*
FROM
TableX
WHERE
ID || '' = 'JOHN'

The question is only if you really need this workaround!
