Timestamp with timezone semantics When reading data, both Redshift TIMESTAMP and TIMESTAMPTZ data types are mapped to Spark TimestampType, and a value is converted to Coordinated Universal Time (UTC) and is stored as the UTC timestamp. For a Redshift TIMESTAMP, the local timezone is assum...
The range of timestamp datatype in redshift is 4713 BC to 294276 AD, also the storage size of timestamp data type is 8 bytes. Storage size of timestamp and timestamptz (timestamp with timezone) datatype is the same as 8 bytes. Timestamp datatype in redshift will stores the maximum ...

RedShift 到 MaxCompute 迁移实践指导 1.概要 本文档详细介绍了Redshift和MaxCompute之间SQL语法的异同。这篇文档有助于加快sql任务迁移到MaxCompute。由于Redshift和MaxCompute之间语法存在很多差异，因此我们需要修改Redshift上编写的脚本,然后才能在MaxCompute中使用，因为服务之间的SQL方言不同。2.迁移前RedShift于MaxCompute...
主要区别 2.1.3复合表达式 2.1.4条件比较 2.1.5DDL语法 主要差异: 1.MaxCompute不支持主键自增和PRIMARY KEY 2.指定默认值default]不支持使用函数 3.decimal指定默认值不支持-1 2.1.6DML语法差异 2.1.7内建函数对比 其他未列出的redshift函数不支持。

Updated the SQL data type representation for timetz/timestamptz from Types.TIME/Types.TIMESTAMP to Types.TIME_WITH_TIMEZONE/Types.TIMESTAMP_WITH_TIMEZONE. [Tim Hsu] Fixed an issue in the Driver API's getTime() method, which previously disregarded the second fraction when attempting to retriev...
