Select CASE Concatenation

Hi All - Smee again!

Two questions but they're unrelated so I'll make 2 posts to keep it clean!

Number one (and I think is the easier one).

I have a SELECT statement, part of which is a "Flags" column which is a CASE
function, but I need to be able to concatenate the results together.
Example: in the below, I need to be show both "@" and "K" if both of the
CASE blocks are true. Possible?

<snip>

CASE WHEN stkeoq(stock.code) = -1 THEN '@'

WHEN stock.kit_pack = 'Y' THEN 'K'

END AS "flags",

<snip>

Note: "stkeoq" is a function

The actual CASE is going to end up with 7 individual tests and therefore 7
difference flags that I'll need to test and concatenate all the true ones.

Thanks,

-p
