    You can select the fields into multiple variables:

    DECLARE @A int, @B int
    
    SELECT
      @A = Col1,
      @B = Col2
    FROM SomeTable
    WHERE ...
    

    Another, potentially better, approach would be to use a table variable:

    DECLARE @T TABLE (
      A int,
      B int
    )
    INSERT INTO @T ( A, B )
    SELECT
      Col1,
      Col2
    FROM SomeTable
    WHERE ...
    

    You can then select from your table variable like a regular table.
