Hi. I'm trying to build a query which would return TRUE or FALSE as
'IsRerun' depending on the matching status with another table, as
follows (simplified query):

SELECT ImportedPINS.PIN,
CASE ManagerReport.PIN
WHEN (IS NULL)
THEN 'FALSE'
ELSE
'TRUE'
END AS IsRerun,
FROM
ImportedPINS LEFT OUTER JOIN ManagerReport
ON ImportedPINS.PIN = ManagerReport.PIN

This version returns "Incorrect syntax near the keyword 'IS'"

I have tried a lot of versions..... like
CASE ManagerReport.PIN
WHEN ManagerReport.PIN IS NULL
THEN 'TRUE'
ELSE
'FALSE'
END AS IsRerun

or

CASE ManagerReport.PIN
WHEN IS NULL
THEN 'TRUE'
ELSE
'FALSE'
END AS IsRerun

or

CASE ManagerReport.PIN
WHEN NULL
THEN 'TRUE'
ELSE
'FALSE'
END AS IsRerun

(this one executes, but ALL show as TRUE, and my data says that out of
200 test records I should have 195 Reruns and 5 Not Reruns)

Please, how should I write this ?
Thanks a lot
Alex.
