  I realise that there is a language barrier here, but your statement doesn't really make sense. Cold you try rewording your statement into a question please, and try to be clearer about your goals and problems?

  Thanks.

  The "from [Test $G_L Entry]" is is not necessary here:
  Select '' as Code from [Test $G_L Entry]

  You could do this:
  Select '' as Code
union
Select distinct [Location Code] as Code from [Test $G_L Entry];

  or this:
  Select '' as Code
union all
Select Distinct[Location Code] as Code from [Test $G_L Entry];

  Note that UNION (not UNION ALL) forces a unique result set. DISTINCT does too. That means that you don't need both UNION and DISTINCT.
