    One option would be to concatenate the values of the rows using for xml path and stuff - along the lines of:

    SELECT DISTINCT ID, 
    STUFF((
            SELECT ', ' + CODE
            FROM #X1
    ORDER BY PrimaryInd DESC
            FOR XML PATH('')
            ), 1, 1, '')
         AS Code
    FROM #X1
