Trying to get a select statement to behave

[ghbeers]

I have a table XYZ which looks something like:

ID POS DO_THESE INQUIRY_ONLY
-- --- -------- ------------
AX 1 A A
AX 2 B C
AX 3 C E
AX 4 D
AX 5 E

AZ 1 U V
AZ 2 V
AZ 3 W

...

I have a list statement with several columns like

ID, NAME, DO_THESE, INQUIRY, ETC

So for the MAINT Column, I want all of the DO_THESE values to appear ONLY when they DO NOT appear in INQUIRY_ONLY for each If and POS.

So if ID = AX, and POS = 1 and DO_THESE is A, I DO NOT want A to appear in the DO_THESE column in that row.

When ID = AX and POS = 2 and DO_THESE is B, I DO want B to appear in the DO_THESE column in that row.

When ID = AX and POS = 3 and DO_THESE is C, I DO NOT WANT C to appear in the DO_THESE column in that row.


So on the final output I want it to appear

ID NAME DO_THESE INQUIRY_ONLY
-- ---- -------- ------------
AX SAM B A
AX SAM D C
AX SAM E

AZ SUE U V
AZ SUE W

...

So when I use EXISTS or NOT EXISTS to populate the D0_THESE column as described above, I either get all or none of them.
Have tried several approaches without success. Tried a CTE and then got duplicate rows for the other columns.

I'm hoping someone can help me find the solution to this problem.

Thank you.

Hi.

Please use TGML tags to FORMAT BOTH your examples. We have no idea where your [highlight #FCE94F]data values[/highlight] go; in the DO or INQ column...

ID	POS	DO_THESE	INQUIRY_ONLY
--	---	--------	------------
AX	1	A       	A
AX	2	B       	C
AX	3	C       	E
AX	4	[b][highlight #FCE94F]D[/highlight][/b]         
AX	5	[b][highlight #FCE94F]E[/highlight][/b]
AZ	1	U       	V	
AZ	2	[b][highlight #FCE94F]V[/highlight][/b]
AZ	3	[b][highlight #FCE94F]W[/highlight][/b]
