Oracle/PLSQL: Translate Function

In Oracle/PLSQL, the translate function replaces a sequence of characters in a string with another set of characters.
However, it replaces a single character at a time.

For example, it will replace the 1st character in the string_to_replace with the 1st character in the replacement_string.
Then it will replace the 2nd character in the string_to_replace with the 2nd character in the replacement_string, and so on.

The syntax for the translate function is:

translate( 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 - All characters in the string_to_replace will be replaced with the corresponding character in the replacement_string.

Applies To:
Oracle 8i, Oracle 9i, Oracle 10g, Oracle 11g

For example:
translate('1tech23', '123', '456); would return '4tech56'
translate('222tech, '2ec', '3it'); would return '333tith'
