-universal operator does not exist. 1.13 With every operator ideal we associate the collection of all Banach spaces X∈ L such that Ix, the identity map of X, belongs to A. The class A so obtained has the following properties: (S1) A contains all finite dimensional Banach spaces. (S2)...
Java类型映射数据库类型的不同,Oracle jdbc驱动程序处理Java String类型可正常映射到数据库的Numberic(Integer),而Postgres则会出错。 另外,则是使用hibernate时经常的錯誤: operator不存在:character varying = bytea问题,不要被这个描述误导了,并不是sql语句中character varying = bytea类型的比较,而是当使用hibernate使...
