For example, if you select 'delete table', the table will be dropped before importing, and then imported
The case of the second derivative scale
If you want to import many tables, it is too troublesome to select the tables one by one, you can write an OSF file and import them in batches.
Example:
2.1 Export
2.1.1 Create a new osf file
Write the table to be exported in the following format:
PL/SQL Developer Object Selection File
N
TABLE " username"."Table1"
TABLE " username"."Table2"
TABLE " Username"."Table 3"
The N in the second row identifies the total number of tables to be exported.
Example:

Click 'Tools' - 'Export Table':
Select users to export:
Right-click one of the tables at will, click 'Load Object Selection':
Select the newly created osf file:
It is found that plsql developer will automatically select the specified table according to the osf file, and then select the directory to store the exported file, and then export it:
2.2 import
The import method is the same as before.
