NUMBER Datatype in Oracle gets converted to Decimal, String (if precision > 28) in parquet file Kindly share some light on the above conversion. And please highlight the point that which resource is responsible for this data type conversion is it ADF internal resource or ADF asks t...
因此,我们能知道,常数0存储占用一个字节,常数1占用两个字节,这跟Oracle数据库存储number机制有关系。 因为有负数、小数点等,Oracle采用了如下方式表示, Oracle中存储的number类型包含3个部分:HEAD(标记占用了几位),DATA,符号位。对正数来说,符号位省略,对0来说,只有80。 Oracle是以十六进制00-FF来表示所有的numbe...
