what oracle query return records field mytable.myname contains any characters other

  1. a-z
  2. a-z
  3. 0-9
  4. -/\()

you can use following:

select * mytable regexp_like (myname, '^[^a-za-z0-9\/\\()-]+$');

you can same i modifier:

select * mytable regexp_like (myname, '^[^a-z0-9\/\\()-]+$', 'i');

  • ^ start of string
  • [^___ ] negative character set (which match character other characters specified inside it)
  • + match previous group more once
  • $ end of string
