NVARCHAR到VARCHAR2插入

Question

我有以下表結構：

UDA_ID (NUMBER) 
Translation (NVARCHAR2) 

我需要在表中插入

UDA_ID (NUMBER) 
Translation (VARCHAR2) 

如何轉換NVARCHAR2到VARCHAR2？

Answer 1

你可以嘗試這樣的：

insert into mytable(Translation) 
(select to_char(Translation) from sometable); 

或類似

insert into mytable(Translation) 
(select to_char('yourValue') from dual);
