将12c代码转换为11g

Question

这是在12 c。如何将此代码转换为11g？ 我尝试使用concat函数但是失败了。任何人都可以帮忙吗？

 CREATE TABLE DimCustomer
(

,FirstName VARCHAR2(50)
,LastName VARCHAR2(50)
,FullName AS (FirstName || ' ' ||LastName)   --calculated column

);

Answer 1

在FirstName

之前删除符号,

CREATE TABLE DimCustomer
(

FirstName VARCHAR2(50)

,LastName VARCHAR2(50)

,FullName AS (FirstName || ' ' ||LastName)   --calculated column


);

它在oracle 11.2.4中工作
