Oracle / PLSQL: TRANSLATE Function

This article is written about how to use the Oracle/PLSQL TRANSLATE feature with syntax and examples.


The Oracle/PLSQL 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 exchange the 1st persona in the string_to_replace with the 1st persona in the replacement_string. Then it will replace the 2nd persona in the string_to_replace with the 2nd character in the replacement_string, and so on.


The syntax for the TRANSLATE function in Oracle/PLSQL is:

TRANSLATE( string1, string_to_replace, replacement_string )

Parameters or Arguments

string1 The string to substitute a sequence of characters with any other set of characters. string_to_replace The string that will be searched for in string1. replacement_string All characters in the string_to_replace will be changed with the corresponding persona in the replacement_string.
