Question

I have data such as:

tblBio

bio        bioid
some data  1
some data  2

tblContact

email        email_pub    bioid
[e-mail]    1            1
[e-mail]   0            2

I need to select

bio + 'email: ' + email WHERE email_pub = 1

I currently have:

SELECT b.bio + 'Email: ' + COALESCE(c.email, '')
FROM tblbio b
INNER JOIN tblContact c ON b.bioid = c.bioid
WHERE c.email_pub = 1
AND b.bioid = 1

However, I ALWAYS need to select bio and then append the text ’email: ‘ as well as the email address onto the end ONLY if email_pub is set to 1. Having the ‘WHERE email_pub = 1’ makes it so that if email_pub is 0 then nothing is selected.

As well, the text ‘Email: ‘ will always show even if there is no published email.

Thank you,

Thomas

Use a CASE:

SELECT b.bio + case when email_pub = 1 then 'Email: ' + COALESCE(c.email, '') else '' end
FROM tblbio b
INNER JOIN tblContact c ON b.bioid = c.bioid
WHERE b.bioid = 1
