Not sure about efficiency, but if the criterion number is @n, do you
mean ...
SELECT LEAST( ABS(MIN(@n-col1)),

I think the formula is just right - very clever. But is it
possible to make
sure that col1, col2 and col3 are all from the same record?
Different question, different answer I ween
:-)
SET @n = ?;
SELECT
id,
MIN( LEAST( ABS(@n-col1), LEAST( ABS(@n-col2), ABS(@n-cl3) ))) AS min

Is there an efficient way to find the closest numerical value, across
three columns? I do not know if there is a way to find it across one.
I thought about plotting the values in a geometric space, but that would
seem to require more dimensions that the server can handle. I thought
about
