I’m still a junior in SQL queries and the Doctrine query builder.
My problem is simple, so simple that I’ve been searching for a few hours.
I’m in a symfony 4.4 LTS project.
I have a table that represents the orders placed on an e-commerce website. There are 4 fields: id, custommer_id, created_at, status
What I want please:
the last 20 past orders that have the status = ‘new’ with ID descendant
If I make a SQL query
SELECT * FROM order o WHERE o.status = 'new'. ORDER BY o.created_at DESC, o.id DESC limit 20
It’s a failure because I don’t get the ids in descending order. I still have trouble understanding why.
Finally I found this solution in SQL:
SELECT * FROM ( SELECT * FROM order o WHERE o.status = 'new'. ORDER by created_at DESC LIMIT 20 ) table_order ORDER by id DESC
Cool!! I’m getting the last 20 commands by descending ID.
Now I have to do it with Doctrine’s createQueryBuilder.
I tried a lot of solutions without success.
Can you please help me?
Thank you in advance
