We currently can’t make a case insensitive orderBy (using orderBy of querybuilder)

@Ginden I don’t know what I’ve changed but its working fine now (even without LOWER()) But it’s not working if I’m sorting using a field of a joined table

for .orderBy('LOWER(information.streetAddress)') (information is a OneToOne relation in user table)

Error: "LOWER(information" alias was not found. Maybe you forgot to join it?

But the request is working If I printSql() and run it manually. Looks like it consider ‘LOWER(’ as part of the alias

[emsitra]

I’ve found an alternative way to solve the issue with the thrown ‘alias was not found’ error. Just added a temporary field with an alias while building a query which helped me to make case insensitive sorting.

e.g. you wanna use : .orderBy('LOWER(information.streetAddress)')

Change it to these expressions in your QB and it should work:

.addSelect('LOWER("information"."streetAddress")', 'info_st_address')
.orderBy('info_st_address', 'ASC')
