存储时间戳值不同PostgreSQL中,当数据类型是WITH TIME ZONE对WITHOUT TIME ZONE？可以用简单的测试用例说明差异吗？
我在PostgreSQL和C#之间搜索了类型转换表,但我找不到任何东西.如果我有空的话,我会在上面的桌子上研究空单元格.但是如果你知道有这些信息的网页,我非常适合你的帮助.
Postgre Type --->C# Type
bigint --->Int64
bigserial --->
bit [ (n) ] --->Byte[]
bit varying [ (n) ] --->Byte
boolean --->Boolean
box --->
bytea --->Byte[]
character varying [ (n) ] ---> String
character --->String
cidr
circle
date --->DateTime
double precision --->Double
inet
integer --->Int32
interval [ (p) ] --->TimeSpan
line
lseg
macaddr
money
numeric [ (p, s) ] --->Decimal
decimal [ (p, s) ] --->Decimal
path
point
polygon
real --->Single
smallint --->Int16
serial
text --->String
time [ (p) ] …我有一个JPA 2应用程序(使用Hibernate 3.6作为JPA实现)使用Postgresql(使用9.0-801.jdbc3 JDBC驱动程序).
我无法将"timestamp with time zone"字段映射到我的JPA实体.
这是一个例子:
CREATE TABLE theme
(
id serial NOT NULL,
# Fields that are not material to the question have been edited out
run_from timestamp with time zone NOT NULL,
run_to timestamp with time zone NOT NULL,
CONSTRAINT theme_pkey PRIMARY KEY (id ),
CONSTRAINT theme_name_key UNIQUE (name )
)
我试图映射如下:
@Entity
@Table(schema = "content", name = "theme")
public class Theme extends AbstractBaseEntity {
private static final long serialVersionUID = 1L;
@Column(name = "run_from") …
