Postgres SELECT where the WHERE is UUID or string

I have the following simplified table in Postgres:

  • id (UUID)
  • uid (varchar)
  • name (varchar)

Answer 1

You could check with a regular expression:

SELECT *
FROM user
WHERE ('jsdfhiureeirh' ~ E'^[[:xdigit:]]{8}-([[:xdigit:]]{4}-){3}[[:xdigit:]]{12}$'
       AND id = 'jsdfhiureeirh')
      OR uid = 'jsdfhiureeirh';
