If a has a "mixed" value, for example a='appmic', then the order of the WHEN clauses is important.

     select case
     when a like '%app%' Then 'Apple'
     when a like '%mic%' Then 'Microsoft'
     end

will return 'Apple', whereas

     select case
     when a like '%mic%' Then 'Microsoft'
     when a like '%app%' Then 'Apple'
     end

will return 'Microsoft'.

Perhaps something worth being aware of?
