我希望将来能找到其中的一个

SELECT productname FROM foo WHERE productname LIKE '%myinput%'
UNION
SELECT productnumber FROM foo WHERE productnumber LIKE '%myinput%'
UNION
...

    LIKE '%myinput%' OR lvn(myinput) < 3
UNION
SELECT productnumber FROM foo WHERE productnumber 
    LIKE '%myinput%' OR lvn(myinput) < 3
UNION
...
