Drop the table first, create the table, and insert data (replace );D. truncate first, and then complete data insertion (truncate ). Feel the effects of these methods for your reference. 1
The new feature after oracle11g makes it possible to omit empty tables when allocating table spaces by default, to reduce the resource usage of tablespaces, so that empty tables are ignored when exporting user data using the EXP export of Oracle, which results in incomplete data and, of course, no way to export data using EXP , this has been mentioned before, do not do too much to repeat the http://jim123.blog.51cto.com/4763600/1934205. Using this method solves the empty table when exporting use
