我得到的错误是：

****** 错误 ******

ERROR: column "t001" does not exist
SQL state: 42703
Character: 3637

我该如何解决这个问题？

Answer 1

字符变化或 char 值必须位于单引号中。如下更改您的查询：

INSERT INTO teamequipment( tid, eid, qty, priceUSD) VALUES('t001', 'e04', 33, 9900.00);

Answer 2

使用t00x插入使用引号时，例如＆＃39; t001＆＃39;。您已将该列声明为char（4）。

Postgres功能错误：列＆＃39; t001＆＃39;不存在
