SQL Case Syntax Issue

[Yu Ong]

Hi

I need help in writing a case script in SQL but I am a beginner so I am doing a lot of cutting an pasteing from existing scripts and changing the variables

I have been trying to get this to work for awhile but being unsuccessful so far.

SELECT OMCOMP, AccountFrom =
CASE
when OMCOMP = 'SG1' and OMDIM1 = 1000 or OMCUST = (SELECT Account FROM Finance.dbo.tes tAccount WHERE Country = 'SG1' THEN '1')
when OMCOMP = 'SG1' and OMDIM1 = 1234 or OMCUST = (SELECT Account FROM Finance.dbo.tes tAccount WHERE Country = 'SG1' THEN '2')
ELSE 'OTHERS'
END
FROM Finance.dbo.tes tFMOSAL

Basically I want to create a table that would show 'AccountFrom' either in '1' or '2' or ' Others'

In the first instance, if OMCOMP is 'SG1' and OMDIM1 is 1000 or if OMCOMP is 'SG1' and OMCUST is equal to a number in another table where country is SG1 then Accountfrom will be equal to 1

Thanks very much in advance for any expertise anyone can offer on my issue.

I don't think

In the first instance, if OMCOMP is 'SG1' and OMDIM1 is 1000 or if OMCOMP is 'SG1' and OMCUST is equal to a number in another

Is the same as this

when OMCOMP = 'SG1' and OMDIM1 = 1000 or OMCUST (SELECT ...

Think about the logic!
I have not looked at the second statement but the first will return true if OMCOMP is 'SG1' and OMDIM1 is 1000
and return true if OMCUST is equal to a number in another.
No other condition will return true
