This used to work fine in Mysql 4.3, but no longer works in 5.5.8:
set @txt='needle';
select * from table where field like CONCAT('%',@txt,'%');
--returns the null set. If I substitute like this:
select * from table where field like '%needle%';
it works perfectly (and as it did in 4.x).
Hi, I just tried this on a schema I had laying about and it worked fine:
mysql SET @dude='pilgrim';
Query OK, 0 rows affected (0.00 sec)
mysql SELECT namefield FROM mytable WHERE namefield LIKE
CONCAT('%',@dude,'%');
+---+
| name
