My bad. The condition on t must be out in the WHERE clause:
SELECT t.variable, t.value, ifnull(d.value, 'off')) state
FROM globals t LEFT JOIN globals d ON (
substr(t.variable,5, length(t.variable)-4) =
substr(d.variable,12, length(d.variable)-11) and
d.variable LIKE 'OUTDISABLE\_%' ESCAPE '\'
)
WHERE t.variable LIKE 'OUT\_%' ESCAPE '\'
ORDER BY t.variable;
Otherwise the result will always include all rows from t.
