在PostgreSQL中，我们拥有多种日期和时间数据类型，包括Date、Time、Timestamp和Interval。Date类型代表公历中的一天；Time类型则表示一天中的时间；Timestamp类型则结合了日期和时间，并可选地包含时区信息。而Interval类型则用于表示时间段或时间间隔，其单位可以是YEAR、MONTH、DAY、HOUR、MINUTE或SECOND等。此外，日期和...
The PostgreSQL “TIMESTAMP” or “TIMESTAMP WITHOUT TIME ZONE” data type stores a timestamp value without the time zone information. In Postgres, the TIMESTAMP and TIMESTAMPTZ data types are similar; the only difference is that one includes the time zone information while the other doesn’t....

JDBC 之 timestamptz | 链接 PostgreSQL 的 TIMESTAMP WITH ZONE 类型对应 JDBC type 是 java.time.OffsetDateTime,不支持 java.time.Instant,但注意 pgsql 并不存储 timezone,所以查出来的 LocalDateTime 跟 Instant 没区别,都是 UTC 时间。还好各种 ORM 库都会支持 Instant,避免用鸡肋的 OffsetDateTime。
I have a PostgreSql table with timestamp with timezone column. I thought that according to the JDBC 4.2, the JDBC Type TIMESTAMP_WITH_TIMEZONE should be mapped to the OffsetDateTime class. Although, if I use something like create table timestamp_test ( id bigserial primary key, ts_col ti...
query使用自定义 SQL 查询读取数据。 例如:"query": "SELECT * FROM \"MySchema\".\"MyTable\""。否(如果指定了数据集中的“tableName”) queryTimeout终止尝试执行命令并生成错误之前的等待时间,默认值为 120 分钟。 如果为此属性设置了参数,则允许的值是时间跨度,例如“02:00:00”(120 分钟)。 有关详细...
