Using SQL Developer 24.3.1.347.1826.
Tools → Database Export…
Export Wizard - Step 1 of 5; Export DDL section, Terminator check box checked.
Accessing Oracle Database release 1102000400: resulting commands with “;” missing. Or programming commands with “/” missing (functions, packages…).
Accessing Oracle Database release 1900000000: results with terminator as expected.
Additional notes:
Selecting a sequence or a table (for example) in Connections navigator, from a database release 1102000400 connection, the SQL tab shows the create command with ‘;’ missing.
From a database release 1900000000 shows the create command terminated with ‘;’.
