The F8 story should show you everything that happened on this tab in SQL Developer (for example, the xyz.sql file).
if you canβt find the story or ddl you want, you should be able to just get ddl by
select * from addmas where colA = 'my criteria' ;
and then click F9, then right-click on the grid and export the data to "insert" and this will create insert statutes for you (remember to insert the table name)
to get CREATE TABLE / VIEW (or an object, not change tables), you can right-click on the table name, select 'edit', then go to DDL (create). If you use this tool for your changes, it will also show you the ddl for change.
