ANNOUNCEMENT: community.oracle.com is currently Read only due to planned upgrade until 29-Sep-2020 9:30 AM Pacific Time. Any changes made during Read only mode will be lost and will need to be re-entered when the application is back read/write.
I added .sql and .ldr as file types via Tools > Preferences > File Types. When I try to open the export.sql file in SQL Developer using the "Import Data" option I get the message: There are no readers registered for the sql type.
I can open the file with SQL Server Management Studio and see all of the insert statements that i would expect to see.
When I created the export.sql file using the Export Wizard with "Format: insert" I received a message: "export.sql was not opened because it exceeds the maximum automatic open size."
