关于 sql:HSQLDB: \\”invalid datetime format\\” for dd/mm/yyyy 但不适用于 yyyy-mm-dd

HSQLDB: "invalid datetime format" for dd/mm/yyyy but not for yyyy-mm-dd

我的表创建如下：

1
2
3
4
5
6
7

CREATE TABLE inventory (
id INTEGER GENERATED BY DEFAULT AS IDENTITY(START WITH 100, INCREMENT BY 1) PRIMARY KEY,
name VARCHAR(30),
department VARCHAR(50),
inventory_type VARCHAR(255),
expiry_date DATE NOT NULL
);

下面是插入到表中的语句：

1
2
3

INSERT INTO inventory (name, department,inventory_type,expiry_date) VALUES ('om', 'Education','Raw', '01/01/2016');
INSERT INTO inventory (name, department,inventory_type,expiry_date) VALUES ('hari', 'HR','Solid' ,'02/02/2016');
INSERT INTO inventory (name, department,inventory_type,expiry_date) VALUES ('hariom', 'Finance','Other', '03/03/2016');

不幸的是，我得到了

Caused by: java.sql.SQLDataException: data exception: invalid datetime
format at org.hsqldb.jdbc.JDBCUtil.sqlException(Unknown Source)

谁能告诉我怎么了？

当我像下面这样更改语句时，它工作正常：

1
2
3

INSERT INTO inventory (name, department, inventory_type, expiry_date) VALUES ('om', 'Education','Raw', '2016-01-01');
INSERT INTO inventory (name, department, inventory_type, expiry_date) VALUES ('hari', 'HR','Solid' ,'2016-02-02');
INSERT INTO inventory (name, department,inventory_type,expiry_date) VALUES ('hariom', 'Finance','Other', '2016-03-03');

Can someone please tell me what is wrong?

答案很简单，如果日期的字符串文字遵循 'yyyy-mm-dd' 格式，HSQLDB 将只接受它们。它愿意提供帮助——在某种程度上——因为它允许我们从"正确的"HSQLDB 日期文字值中省略 DATE 关键字

1	DATE '2016-01-02'

让我们简单地提供

1	'2016-01-02'

但它不会接受 '01/02/2016' (无论如何这是模棱两可的)或我们愚蠢的人类可以表示日期的许多其他方式中的任何一种。
