Hi,

Please help me, i try to fetch category list as like below, where category ids is passed in inclause, it returns two rows.

mysql> select c_id,c_name from category where c_id in (870,854);
+------+---------------+
| c_id | c_name        |
+------+---------------+
|  854 | Telugu        |
|  870 | Telugu Events |
+------+---------------+


Whereas same category id is concatenated and passed to inclause as parameter, but its returning only one row insted of two rows.

mysql> select c_id,c_name from category where c_id in (select concat(870,',',854) as c_id);
+------+---------------+
| c_id | c_name        |
+------+---------------+
|  870 | Telugu Events |
+------+---------------+

Please clarigy me.

Thanks.

CONCAT is a string function, am surprised you even get that one row. The query you get is:

select c_id,c_name from category where c_id in ('870,854');

My guess is that the string is being casted to an int again, resulting in 870.

Hi,

Its returnig only one result as you mentioned, is it possible to get two rows by modifying something in the same qyery?

Thanks.

Yes, it's possible, but I recommend using the first one.

This should work I think:

SELECT c_id, c_name 
FROM category 
WHERE FIND_IN_SET(c_id, (SELECT CONCAT(870,',',854) AS c_id))
