"pdt_list" syntax : sdomain prefix domain

  • '.' (dot) means NULL value and will match anything
  • the comparison operation is 'START WITH' -- if domain is 'a' then all domains starting with 'a' are listed

Examples pdt_list o 2 . - lists the entries where sdomain is starting with 'o', prefix is starting with '2' and domain is anything

pdt_list . 2 open - lists the entries where sdomain is anything, prefix starts with '2' and domain starts with 'open'
