No type2 like "% 2" directly, you can try:
SELECT "22,33" LIKE "%2%";the result is not 0.
need to use FIND_IN_SET:
where FIND_IN_SET('2', type2) > 0;like is a wide range of fuzzy matches, with no delimiter in the string, find_in_set is an exact match, and field values are in English "," delimited
SELECT * FROM A where find_in_set (type2,2);
several solutions

select * from table_name t where t.type2 like'% 2%'
$selectTip = $pdo->query("SELECT * FROM `tips_rate` WHERE `tip_id` = ".$row[ id ]." " ); $selecttotal = mysqli_num_rows($selectTip); $rate = $pdo->query("SELEC...
