Learn how to use the Oracle/PLSQL REPLACE function with syntax and examples.
The Oracle/PLSQL REPLACE function replaces a sequence of characters in a string with another set of characters.
The syntax for the Oracle/PLSQL REPLACE function is:
REPLACE( 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.
