Question

I need a SQL Server and Oracle compatible query to get the following result

Table:

PRIMARY IDN   SECONDARY_IDN    STATUS 
1             47               Pending
2             47               Completed
3             47               Error
4             57               Pending
5             59               Completed
6             60               Pending
7             60               Completed

My input would be either Pending, Completed, or Error.

I need to list out all the secondary IDN with just 1 status and that is the input status.

For example my input is Pending: it should show up 57 ONLY. Others might have Pending but it also has completed and error records .

Can you please help me ?

Answer 1

SELECT  SECONDARY_IDN
FROM    tableName
GROUP   BY SECONDARY_IDN
HAVING  SUM(CASE WHEN Status = 'Pending' THEN 1 ELSE 0 END) = COUNT(*)
