The REPLACE function replaces all or part of a text string with another string, based on the number of characters you specify. REPLACEB replaces all or part of a text string with another string, based on the number of bytes you specify.




Note: The REPLACE function is similar to the SUBSTITUTE function, but the REPLACE function replaces text in a specified position of a supplied string, while the SUBSTITUTE function replaces one or more instances of a given text string.

Note: REPLACEB counts 2 bytes per character only when a double-byte character set (DBCS) language is set as the default language. Otherwise REPLACEB behaves the same as REPLACE, counting 1 byte per character.
