SQLRF51919Purpose

TO_SINGLE_BYTE returns char with all of its multibyte characters converted to their corresponding single-byte characters. char can be of data type CHAR, VARCHAR2, NCHAR, or NVARCHAR2. The value returned is in the same data type as char.

Any multibyte characters in char that have no single-byte equivalents appear in the output as multibyte characters. This function is useful only if your database character set contains both single-byte and multibyte characters.

This function does not support CLOB data directly. However, CLOBs can be passed in as arguments through implicit data conversion.
