转换日期postgreSQL时出错

Question

我正在尝试使用以下代码将varchar转换为日期，并输出以下错误，任何想法为什么？

ALTER TABLE import.employee
ALTER COLUMN birth_date
TYPE date
USING (birth_date::date);

---

    ERROR:  date/time field value out of range: "05/29/1960"
HINT:  Perhaps you need a different "datestyle" setting.
********** Error **********

ERROR: date/time field value out of range: "05/29/1960"
SQL state: 22008
Hint: Perhaps you need a different "datestyle" setting.

Answer 1

如果您需要从birth_date获取:: date，请先使用Data Type Formatting Functions文档中的给定函数将DATE格式提供给您的字段。
