In Oracle, you can use the CAST function to convert NVARCHAR to VARCHAR or VARCHAR to NVARCHAR. Here is an example:

Convert NVARCHAR to VARCHAR.

SELECT CAST(N'你好' AS VARCHAR2(10)) AS converted_text FROM dual;

Convert VARCHAR to NVARCHAR.

SELECT CAST('hello' AS NVARCHAR2(10)) AS converted_text FROM dual;

In the previous example, we used the CAST function to convert NVARCHAR to VARCHAR, or VARCHAR to NVARCHAR, and display the converted results in the query.
