You're right. My mistake!
Fixed in 2.9.2
from openrecord.
This is normal SQL behavior. OFFSET
and LIMIT
will be applied to the result set.
So a SELECT COUNT(*) FROM your_table
will return one row. With an offset of 1 you will skip the result and get nothing... This is the behaviour of postgres an sqlite. MySql will ignore the offset and return the count.
regarding updateAll
: Yes, that's not implemented. It's not very precise to updated your records this way. It's better to use a where
clause to limit the number of affected rows.
e.g.
await Model.where({id_between: [1, 5]}).updateAll({ updatedAt: new Date() })
from openrecord.
Yes the count part was more of a wish the framework could bend the query and make it work as length but you are right.
About updateAll, in my app i was already filtering with where but wanted to do something like: where userId = ... and ..., after ordering by updatedAt desc, offset 5 and update the rest removing a premium flag feature as the user will only be able to keep 5 records with the flag after losing the premium status.
I could fetch the records first and then update them but tried to use updateAll to update them with only one trip do database.

ahhh, okay!
UPDATE your_table SET foo = 'bar' LIMIT 2
is also no valid SQL. But we could imitate it via
UPDATE your_table SET foo = 'bar' WHERE id IN (SELECT id FROM your_table ORDER BY id LIMIT 2)
I've added the possibility to do this kind of subqueries in UPDATE
and DELETE
queries.
Checkout the latest version!

Thx that is great! I was about to do it using a mix of .toSql and .raw but now it's way easier.
But i'm getting error at this line if i use .delete or .deleteAll without any filter (where or limit etc), like await Model.deleteAll()
to help clear DB on tests
Similarly, also here if using await Model.updateAll({ ... })
TypeError: this.getInternal is not a function
