Question

I have fetching record from table named Pizza_Table.

Pizza_table Schema

id | pizza name | pizza_topping_ids
1  | pizza1     |1,2,3
2  | pizza2     |2,3
3  | pizza3     |4,5,6

Actually my functionality is searching pizza based on pizza_topping_ids
I have work allot in this searching. but I can’t find proper solution. .

I can’t use IN clause for fetching record.

I have tried out :

1)

 SELECT * 
 FROM `pizza_table` 
 WHERE `pizza_topping_id` REGEXP '[[:<:]]2[[:>:]]'

Problem : fetch all record having value 2

2)

SELECT * 
FROM `pizza_table` 
WHERE `pizza_topping_id` REGEXP '[[:<:]]1,2,3,4[[:>:]]' 

but MySQL returned an empty result set,

If comma separated values are not match to any record then return result which is most having value in topping_id column.

EX: If i have run above query for find out pizza having 1,2,3,4 topping_id, but In database no pizza exist having such topping_id combination then result will be most covered id should be displayed like ‘pizza1’ having pizza_topping_id 1,2,3.

Sorry for bad English as well as format, but try to understand my problem.
Thanks in advance.

Please help me.

Answer 1

Just try this-

SELECT * FROM `pizza_table` WHERE  FIND_IN_SET(2,pizza_topping_id)

OR REGEXP

SELECT * FROM `pizza_table` WHERE pizza_topping_id REGEXP '^2,|,2$|,2,' OR pizza_topping_id =2
