postgresql - Postgres : ERROR: operator does not exist: character varying = bigint

Question

我的查询是这样的。我尝试获取 ID 列表的状态。

select order_number, order_status_name
from data.order_fact s
join data.order_status_dim l
on s.order_status_key = l.order_status_key
where 
order_number in (1512011196169,1512011760019,1512011898493,1512011972111)

虽然我得到了一个错误:

ERROR:  operator does not exist: character varying = bigint
LINE 6: order_number in (1512011196169,1512011760019,1512011898493,1...
                     ^
HINT:  No operator matches the given name and argument type(s). You might need to add explicit type casts.

关于我应该如何修改 ID 以使其正常工作，您是否有任何线索？ 非常感谢!

Answer 1

您的 order_number 是一个 varchar，您不能将它与数字进行比较(123 在 SQL 中是一个数字，'123'是一个字符串常量)

您需要使用字符串文字:

order_number in ('1512011196169','1512011760019','1512011898493','1512011972111')
