Question

我正在使用talend将数据插入Amazon Redshift上的表中。 talend产生了Java代码，但是Amazon Redshift不支持today()函数。

我正在尝试从Salesforce加载表，并使用talend将其放入Redshift。当我从talend运行作业时，出现以下错误：

Exception in component tRedshiftOutput_1

Amazon Redshift似乎不支持today()功能。

我想知道如何解决这个问题？

您可以改用CURRENT_DATE函数。您可以在Redshift日期和时间功能文档中找到更多信息：https://docs.aws.amazon.com/redshift/latest/dg/Date_functions_header.html
