In Oracle database, the CONVERT function is used to convert a string from one character set to another. Its syntax is:

CONVERT(string, target_charset, source_charset)

In the code, ‘string’ represents the string to be converted, ‘target_charset’ indicates the target character set, and ‘source_charset’ refers to the original character set for the conversion.

For example, to convert a string from the UTF-8 character set to the GBK character set, you can use the following statement:

SELECT CONVERT('你好', 'GBK', 'UTF8') FROM dual;

This will return a string encoded in the GBK character set. The CONVERT function is very useful for handling special character set conversions, such as converting from the Unicode character set to another character set.
