Starting with Oracle8i, Oracle supports two types of tablespace: The Data Dictionary management table space and the localized managed table space. And Oracle has been recommending users to use the locally managed tablespace. We know that in a localized managed table space, the data file space is managed by a bitmap in the file header of the document itself. The h
After the last write, how do I export the data structure and data ([Tips] exporting table structures and data from DB2). Now I have finally finished writing how to import the table structure.
The first step is to create a database. You can use control center or command line. However, for this new database, I prefer command editor.After opening, you can directly w
