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.

Syntax

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.
