But perhap= s there is a way to put the two separate CASE statements together with a || concatenation: CASE WHEN stkeoq(stock.code) =3D -1 THEN '@' ELSE '' END || CASE WHEN stock.kit_pack =3D 'Y' THEN 'K' ELSE '' END AS "flags" Is this what you are looking for? -Aaron Bono ------=_Part_106971_13711775.1152261845998 Content-Type: text/html; charset=WINDOWS-1252 Content-Transfer-Encoding: quoted-printable Content-Disposition: inline On 7/7/06, Phillip Smith <phillips@weatherbeeta.com.au> wr= ote:

= 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=85 Possible?

&= nbsp;    <snip>

&= nbsp;    CASE WHEN stkeoq(stock.code) =3D -1 THEN '@'

&= nbsp;          WHEN stock.kit_pack =3D 'Y' THEN 'K'

&= nbsp;    END AS "flags",

&= nbsp;    <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=85

<= br>With a CASE you will need to provide all possible combinations.  Bu= t perhaps there is a way to put the two separate CASE statements together w= ith a || concatenation:

CASE WHEN stkeoq(stock.co= de) =3D -1 THEN '@'
ELSE ''
END
||
CASE WHEN stock.kit_pack =3D 'Y' THEN 'K'
ELSE ''
END
