如何为列字段获取两行之间的差异？

SELECT 
    column1, 
    column2, 
    column3, 
    column4, 
    column5, 
    column6, 
    column7, 
    column8, 
    column9, 
    column10
FROM 
    table1
WHERE 
    column1 = 'value1'
    AND column2 = 'value2'
    AND column3 = 'value3'
    AND column4 = 'value4'
    AND column5 = 'value5'
    AND column6 = 'value6'
    AND column7 = 'value7'
    AND column8 = 'value8'
    AND column9 = 'value9'
    AND column10 = 'value10'

SELECT DISTINCT 
    column1, 
    column2, 
    column3, 
    column4, 
    column5, 
    column6, 
    column7, 
    column8, 
    column9, 
    column10
FROM 
    table1
WHERE 
    column1 = 'value1'
    AND column2 = 'value2'
    AND column3 = 'value3'
    AND column4 = 'value4'
    AND column5 = 'value5'
    AND column6 = 'value6'
    AND column7 = 'value7'
    AND column8 = 'value8'
    AND column9 = 'value9'
    AND column10 = 'value10'
EXCEPT
SELECT DISTINCT 
    column1,
