You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: schema_dumper.rb
    path of file: ./repos/activerecord-sqlserver-adapter/lib/active_record/connection_adapters/sqlserver
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

module ActiveRecord
  module ConnectionAdapters
    module SQLServer
      class SchemaDumper < ConnectionAdapters::SchemaDumper
        SQLS
    
        def schema_collation(column)
          return unless column.collation

          # use inspect to ensure collation is dumped as string. Without this it's dumped as
          # a constant ('collation: SQL_Latin1_General_CP1_CI_AS')
          collation = column.collation.inspect
          # use inspect to ensure string comparison
          default_collation = @connection.collation.inspect

          collation if collation != default_collation
        end
