I use the following query to update my database. It does not work, giving me a syntax error. Any Ideas?

UPDATE table
SET browser = CASE ID
WHEN '11' THEN 'Google Chrome 2.0'
WHEN '49' THEN 'Google Chrome 2.0'
WHEN '52' THEN 'Google Chrome 2.0'
END, SET os = CASE ID
WHEN '11' THEN 'Microsoft Windows'
WHEN '49' THEN 'Microsoft Windows'
WHEN '52' THEN 'Microsoft Windows'
END, SET language = CASE ID
WHEN '11' THEN 'US English 5'
WHEN '49' THEN 'US English 5'
WHEN '52' THEN 'US English 5'
END WHERE ID IN (11,49,52)

Thanks,
