Let me first show you my table:
INSERT INTO my_table(name, brand, source)
VALUES ('Abc', 'Abc', 'Orig'),
('Auchan', 'Auchan', 'Orig'),
('Auchan', 'Auchan', 'Added'),
('dj-auchan-djd', 'Auchan', 'Added'),
('Auchan', 'Other', 'Added'),
('Other', 'oj_auchan', 'Added'),
('Other', 'Other', 'Added');
What I want to do is to delete data where source is 'Added' and brand or name is like brand where source is 'Orig'. For example here we will delete next rows:
('Auchan', 'Auchan', 'Added'), - simply name and brand is 'Auchan'
('dj-auchan-djd', 'Auchan', 'Added'), - brand ad name has 'Auchan'(but name lowercase)
('Auchan', 'Other', 'Added'), - name is 'Auchan'
('Other', 'oj_auchan', 'Added') - brand has 'Auchan' but lowercase.
So what it would be when we manually create this brands comparing:
delete
from my_table
where lower(name) ~~ any
('{%auchan%,
