Thread: Sub SELECTS

Sub SELECTS

I have a select query with 2 sub selects.
When I run that query CPU usage goes to 98% for postgres.
Does sub selects eat more resources and slower the queries?
Is there any alternatives to sub selects?

It depends on what you're doing.  The query and table schema
would be useful.
