我有一个关于在SAS中从TeraData执行/* 1 */

函数的问题。例如，在执行下面的代码时，我将在代码下面收到错误消息。在从TeraData创建表后，除了在SAS中使用年份函数之外，还有办法执行year()函数吗？
year()
select * from connection to teradata (
select customer_id
, year(date)
from base.customers a
);
答案 0 :(得分：4)
您收到错误，因为Teradata中没有YEAR功能。相反，您可以使用Extract()：
select * from connection to teradata (
select customer_id
, EXTRACT(YEAR FROM date)
from base.customers a
);
