      You also can use table aliases, however the setup is a bit hairy:

      # searching for `true` result
      users.select_append { string::case(id.is(1) => 'one', else: 'else').as(:one_or_else) }
      ```
  - |-

        gateway.(:pg_advisory_xact_lock, 1234) # => nil
      ```
  - |-

        end
      ```
  - |-
    `SQL::Relation#import` inserts data from another relation using the `INSERT ... AS SELECT` syntax which is often far more effective than row-by-row processing and an ordinary multi-insert.

         users.where { lower(name).not('John') }
      ```

  - |-
    Support for`EXISTS` (v-kolesnikov)
