Hi All,

I have a table with organizations. Within that table there are Organization_IDs and Organization_Parent_IDs. These two values should correspond to each-other or the Organization_Parent_IDs value should be null. Can you please tell me how I can go about searching for orphaned organizations?

Thanks,
Mark

SELECT *
FROM <Table>
WHERE (Organization_Parent_ID NOT IN (SELECT DISTINCT Organization_ID FROM <table>))
AND Organization_Parent_ID IS NOT NULL

HTH,

SELECT *
FROM Organizations o
WHERE NOT EXISTS (SELECT 1
FROM Organizations
WHERE Organization_IDs = o.Organization_Parent_IDs 
)
AND Organization_Parent_IDs IS NOT NULL
