2. Create Oracle data table
Create table:
1. Create data table space
2. Create user (specify the default table space currently created)
Delete table:
1. Delete the user
2. Delete the data table space
The order cannot be reversed. If you delete the data table first, the user’s default table space will not be found. Open Do not open the database.
After the deletion is completed, manually delete the table space in the disk.
When creating a table space, the name must be in uppercase letters, otherwise an error will occur when the path is found after creation.
When creating a user, the default table space is the one just created.
Assign permissions
