This used to work fine in Mysql 4.3, but no longer works in 5.5.8:

set [at] txt='needle';
select * from table where field like CONCAT('%', [at] 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).

How can I get this to work in 5.5.x?

Thanks,

-Hank

Hi, I just tried this on a schema I had laying about and it worked fine:

mysql> SET [at] dude='pilgrim';
Query OK, 0 rows affected (0.00 sec)

mysql> SELECT namefield FROM mytable WHERE namefield LIKE
CONCAT('%', [at] dude,'%');
+-----------------------------------------------+
| name |
+-----------------------------------------------+
| Blood Elf Pilgrim |
| Blood Elf Pilgrim |
| Draenei Pilgrim |
| High Elf Pilgrim |
| Pilgrim Gal'ressa |
| Recovering Pilgrim |
| Wounded Blood Elf Pilgrim |
| Young Pilgrim |
+-----------------------------------------------+

I am running 5.5.6 x64 on Mac OS X.
