How to generate a DDL and a DML in Oracle SQL (Scriptable) - oracle

Question

I want to generate a .DDL that contains all the 'CREATE TABLES' and a .DML that contains all the 'INSERT'
I tried to use the answers of this question but didn't get to modify them to get the DDL and the DML

Answer 1

The question you referenced lets you get the DDL, to get the DML its easiest to use a tool. SQLcl is free and lets you do it easily, eg
SQL> select * from scott.emp;
EMPNO ENAME JOB MGR HIREDATE SAL COMM DEPTNO
---------- ---------- --------- ---------- --------- ---------- ---------- ----------
7369 SMITH CLERK 7902 17/DEC/80 800 20
7499 ALLEN SALESMAN 7698 20/FEB/81 1600 300 30
7521 WARD SALESMAN 7698 22/FEB/81 1250 500 30
7566 JONES MANAGER 7839 02/APR/81 2975 20
...
14 rows selected.
SQL> select /*insert*/ * from scott.emp;
REM INSERTING into SCOTT.EMP
SET DEFINE OFF;
Insert into SCOTT.EMP (EMPNO,ENAME,JOB,MGR,HIREDATE,SAL,COMM,DEPTNO) values (7369,'SMITH','CLERK',7902,to_timestamp('17/DEC/80','DD/MON/RR HH12:MI:SSXFF AM'),800,null,20);
Insert into SCOTT.EMP (EMPNO,ENAME,JOB,MGR,HIREDATE,SAL,COMM,DEPTNO) values (7499,'ALLEN','SALESMAN',7698,to_timestamp('20/FEB/81','DD/MON/RR HH12:MI:SSXFF AM'),1600,300,30);
Insert into SCOTT.EMP (EMPNO,ENAME,JOB,MGR,HIREDATE,SAL,COMM,DEPTNO) values (7521,'WARD','SALESMAN',7698,to_timestamp('22/FEB/81','DD/MON/RR HH12:MI:SSXFF AM'),1250,500,30);
Insert into SCOTT.EMP (EMPNO,ENAME,JOB,MGR,HIREDATE,SAL,COMM,DEPTNO) values (7566,'JONES','MANAGER',7839,to_timestamp('02/APR/81','DD/MON/RR HH12:MI:SSXFF AM'),2975,null,20);
Insert into SCOTT.EMP (EMPNO,ENAME,JOB,MGR,HIREDATE,SAL,COMM,DEPTNO) values (7654,'MARTIN','SALESMAN',7698,to_timestamp('28/SEP/81','DD/MON/RR HH12:MI:SSXFF AM'),1250,1400,30);
Insert into SCOTT.EMP (EMPNO,ENAME,JOB,MGR,HIREDATE,SAL,COMM,DEPTNO) values (7698,'BLAKE','MANAGER',7839,to_timestamp('01/MAY/81','DD/MON/RR HH12:MI:SSXFF AM'),2850,null,30);

Getting the DDL is easier now, it's a built-in command for SQL Developer and SQLcl.
For EMPLOYEES table, bonus: grabbing dependent objects on the table.
cd c:\users\jdsmith\desktop
set feedback off
set ddl segment_attributes off
set ddl storage off
set ddl tablespace off
spool employees_so.sql
ddl employees
set sqlformat insert
select * from employees;
spool off
Run this via F5 in SQL Developer (desktop) or SQLcl (cli at shell).
Out pops this file -

Answer 3

To adapt #ThatJeffSmith's answer
If you have three tables: employees, departments, jobs then you can use:
cd c:\users\jdsmith\desktop
set feedback off
set ddl segment_attributes off
set ddl storage off
set ddl tablespace off
spool myschema.ddl
ddl employees
ddl departments
ddl jobs
spool off
spool myschema.dml
set sqlformat insert
select * from employees;
select * from departments;
select * from jobs;
spool off
