Where is the implicit conversion from Query to UnitInvoker comming from?

Question

In these examples ( https://github.com/szeiger/scala-query/wiki/Queries) foreach (via for comprehension) is used on a scalaquery Query.

But foreach doesn't seem to be present in Query, but only in UnitInvoker.

Where is the implicit conversion comming from that converts from Query to UnitInvoker?

Answer 1

Short answer: from the BasicImplicitConversions trait.

Usually with ScalaQuery you'll bring these conversions into scope by importing the contents of the Implicit field of the profile for your driver:

import org.scalaquery.ql.extended.H2Driver.Implicit._
