I need to fetch out a portion of a string which comes after  first instance of the predefined string pattern..For instance,in the string "D-Brown" ,I need to fetch whatever which comes after "D-".I tried using whatcomesafterfirst() function but it will accept only character value as a predefined pattern and not string.Can anyone help me to find any existing fuction/way to deal with this ?
