REPLACE Syntax in Oracle

Oracle-Specific Function Signature

REPLACE(source_string, search_string [, replacement_string])
  • source_string: The text value to be searched.

  • search_string: The substring to find.

  • replacement_string (optional): The text to replace search_string with (default: empty string).

Note: In Oracle, omitting replacement_string removes search_string from the source.
