MySQL Finding most frequent value in multiple columns -


i have table this:

  • votingid president_vote vice_president_vote senator_vote ...
  • 1000 1023 1102 1042
  • 1001 1102 1047 1102
  • 1002 1023 1047 1042
  • ...

so need find person(id) has votes each position, outcome ideally looks this

  • president_vote vice_president_vote senator_vote ...
  • 1023 1047 1042

there 5 columns in table possible find frequent value each column , brutally cross join them all. however, lets assume there 5000 columns exist in table. how can write query find out frequent value appears in each columns together? thanks!
