Distinct and OrderBy Unindexed field
Author: falahatiCreated Oct 12, 2020Updated Oct 12, 2020
A simple query as follow works great:
await db
.select(lf.fn.distinct(table.id))
.from(table)
.orderBy(table.id, lf.Order.ASC)
.limit(10)
.exec();or even by an string field:
await db
.select(lf.fn.distinct(table.id))
.from(table)
.orderBy(table.title, lf.Order.ASC)
.limit(10)
.exec();But ordering by date doesn't work in my case:
await db
.select(lf.fn.distinct(table.id))
.from(table)
.orderBy(table.created, lf.Order.ASC)
.limit(10)
.exec();By not working I mean it gives me a result that doesn't change if I modify the order to DESC or ASC. It just returns a static result as if the date created is zero or the same number for all rows. Checked manually and each row does in fact have a different value.
Removing the distinct function fixes the problem.
If you need any additional information, please ask.
