Hasilkan DDL dengan Oracle Sql Developer untuk memasukkan kunci Asing

Quick DDL tidak menggunakan preferensi apa pun, ia melakukannya dengan apa yang menurut kami tepat - yang tentu saja sangat subjektif.

Namun, jika Anda membuka halaman SQL untuk objek di pohon, DDL akan dibuat mengikuti preferensi yang ditetapkan di Preferensi> Basis Data> Ekspor.

Untuk versi 4.2, Anda juga dapat menggunakan perintah DDL di lembar kerja. Dan Anda dapat menggunakan SET DDL untuk mematikan atau menghidupkan jenis DDL yang ingin Anda buat.

SET DDL PRETTY ON;
SET DDL CONSTRAINTS ON;
SET DDL REF_CONSTRAINTS ON;
SET DDL PARTITIONING ON;
SET DDL TABLESPACE OFF;
SET DDL SEGMENT_ATTRIBUTES OFF;
SET DDL STORAGE OFF;
