Question

Table 1

Mail              Special Quote (Y/N)

[e-mail]     Blank 
[e-mail]          Blank
[e-mail]         Blank

Table 2

Email Address     Dept

[e-mail]     Config 
[e-mail]          Finance
[e-mail]         Marketing 

Now I want Table 1 updated to Y where the matching email address in Table 2 is coming from Finance or Marketing .

UPDATE TABLE 1 
Set Special Quote to be Y 
where in TABLE 2 the Dept is Finance or Marketing for the matching email address.

Probably just having a brain freeze and need some coffee .

Thinking left join on email address then throw in a bit of a case statement perhaps for the Y and N bit ?

Answer 1

Try the following:

UPDATE A
SET A.SpecialQuote = 'Y'
FROM Table1 A
INNER JOIN Table2 B
ON A.Mail = B.EmailAddress
WHERE B.Dept IN ('Finance','Marketing')
