When created with the CACHE option, an unexpected shutdown, such as a power failure, can lose the sequence numbers in the cache. If there are multiple instances of the NEXT VALUE FOR function specifying the same sequence generator within a single Transact-SQL statement, all those instances ...

Multiple calls to the NEXT VALUE FOR function for the same sequence generator in a single statement must all use the same OVER clause definition. Again, this is obvious. Multiple calls to the NEXT VALUE FOR function that reference different sequence generators in a single statement can have di...
问题是,我们现在需要使用自动主键生成,MySQL使用GenerationType.IDENTITY,Oracle使用GenerationType.SEQUENCE,此外,在一些罕见的情况下,我们需要自己手动设置主键注释类中的以下代码用于两个数据库的自动密钥生成,但如果主键是自设置的,则失败。="sequence_generator",...
