Select data from query1 where option = and != together - sql

Question

help me please.
I having result set (table). To get the this first result set, I make a selection with three joins. To get all the necessary characteristics of the goods ( 05_A and 05_B and some descriptions)
We can see stock items.
for example:
artid | warehousetype
001 | 05_A
001 | 05_B
002 | 05_A
I need to select all artid where warehouse type in 05_A and not in 05_B (ex. 002)
I'm try:
select * from table where warehousetype like 05_A and warehousetype not like 05_A - it's not work.
I'm try
select * from table where warehousetype like 05_A
MINUS
select * from table where warehousetype like 05_B
it's works but i'm see all stock w\o 05_B, but need see only artid where whtype = 05_A and not 05_B
How do make my report?

Answer 1

You can use the NOT EXISTS clause along with a subquery to achieve the desired result.
SELECT artid
FROM table
WHERE warehousetype = '05_A'
AND NOT EXISTS (
SELECT artid
FROM table table2
WHERE warehousetype = '05_B'
AND table.artid = table2.artid
);
You can also use a JOIN with a negation condition on the joined table to get the same result.
SELECT t1.artid
FROM table t1
LEFT JOIN table t2 on t1.artid = t2.artid and t2.warehousetype = '05_B'
WHERE t1.warehousetype = '05_A'
AND t2.artid is null

Answer 2

You can use Oracle's MINUS operator, to subtract all "artid" values that have '05_B' from all records that have '05_A'.
SELECT artid FROM tab WHERE warehousetype = '05_A'
MINUS
SELECT artid FROM tab WHERE warehousetype IN ('05_B')

Answer 3

With your sample data ...
ARTID
WAREHOUSETYPE
001
05_A
001
05_B
002
05_A
...you could use LISTAGG analytic function to get a list of warehouse types per ARTID:
SELECT ARTID, WAREHOUSETYPE,
LISTAGG(WAREHOUSETYPE, ', ') WITHIN GROUP (Order By WAREHOUSETYPE) OVER(Partition By ARTID) "WH_LIST"
FROM tbl
ARTID
WAREHOUSETYPE
WH_LIST
001
05_A
05_A, 05_B
001
05_B
05_A, 05_B
002
05_A
05_A
With this WH_LIST you can use LIKE and NOT LIKE ...
SELECT ARTID, WAREHOUSETYPE
FROM ( SELECT ARTID, WAREHOUSETYPE,
LISTAGG(WAREHOUSETYPE, ', ') WITHIN GROUP (Order By WAREHOUSETYPE) OVER(Partition By ARTID) "WH_LIST"
FROM tbl )
WHERE WH_LIST LIKE '%05_A%' And WH_LIST NOT LIKE '%05_B%'
Result:
ARTID
WAREHOUSETYPE
002
05_A

Answer 4

This is the simplest possible way to do this. In the inner query you get every art id with warehouse '05_B' with it. Then you exclude all those ids from the list of ids where warehousetype '05_A' matches with.
SELECT artid FROM table
WHERE warehousetype = '05_A' AND artid
NOT IN(
SELECT artid
FROM table
WHERE warehousetype = '05_B'
);
I did not test it so please correct if there is any syntax issues or whatsoever. Except for that its should be working perfectly.
