Preamble
The Oracle/PLSQL TRANSLATE function replaces the sequence of characters in a string with another character set. However, it replaces one character at a time.
For example, it replaces the first character in string_to_replace with the first character in replacement_string. Then the second character in string_to_replace with the second character in replacement_string will be replaced, and so on.
