In Oracle/PLSQL, the replace function replaces a sequence of characters in a string with another set of characters.
The syntax for the replace function is:
replace( string1, string_to_replace, [ replacement_string ] )
string1 is the string to replace a sequence of characters with another set of characters.
string_to_replace is the string that will be searched for in string1.
replacement_string is optional. All occurrences of string_to_replace will be replaced with replacement_string in string1. If the replacement_string parameter is omitted, the replace function simply removes all occurrences of string_to_replace, and returns the resulting string.

For example:
replace('123123oracle', '123'); | would return 'oracle' |
replace('123oracle123', '123'); | would return 'oracle' |
replace('222oracle', '2', '3'); | would return '333oracle' |
