Hello @ARNDUP,

The issue you faced is not related to the ifs itself; it is due to an incorrect query expression. Please use ‘ip.part’ after the ‘group by’ statement and and include a ‘having’ statement before the ‘case when’ expression in the last line. As follows;

SELECT 
CASE WHEN ip.PART_NO LIKE concat(&Type1, '%') THEN 'Electrique'
WHEN ip.PART_NO LIKE concat(&Type2, '%') THEN 'Roulement'
ELSE 'Autres' 
END type_article,
count(ip.PART_NO)
FROM INVENTORY_PART ip 
WHERE SECOND_COMMODITY = '300'
GROUP BY ip.PART_NO having CASE WHEN ip.PART_NO LIKE concat(&Type1, '%') THEN 'Electrique'
WHEN ip.PART_NO LIKE concat(&Type2, '%') THEN 'Roulement'
ELSE 'Autres'
END

Regards,

Umran

Hello;

If you try this way you won't get any errors

select
ab.type_article,
count(ab.part_no) as part_count
from
(
SELECT 
CASE WHEN ip.PART_NO LIKE concat(&Type1, '%') THEN 'Electrique'
WHEN ip.PART_NO LIKE concat(&Type2, '%') THEN 'Roulement'
ELSE 'Autres' 
END type_article,
ip.PART_NO
FROM INVENTORY_PART ip 
WHERE ip.SECOND_COMMODITY = '300'
) ab
group by
ab.type_article
