How to export data and SQL sentence?

Question

Hi all,
I need to create SQL sentences with INSERT INTO clauses of exported data from a table to populate another table?
Thanks and best regards,

Answer 1

Inserting one row at a time is inefficient.
You can do this instead
SQL> select decode(rownum,1,'Insert all'||chr(13),'     ')||
  2  'into emp (empno,ename) values ('||empno||','''||ename||''')' from emp
  3  /
DECODE(ROWNUM,1,'INSERTALL'||CHR(13),'')||'INTOEMP(EMPNO,ENAME)VALUES('||EMPNO||','''||ENAME||''
Insert all into emp (empno,ename) values (7369,'SMITH')
     into emp (empno,ename) values (7499,'ALLEN')
     into emp (empno,ename) values (7521,'WARD')
     into emp (empno,ename) values (7566,'JONES')
     into emp (empno,ename) values (7654,'MARTIN')
     into emp (empno,ename) values (7698,'BLAKE')
     into emp (empno,ename) values (7782,'CLARK')
     into emp (empno,ename) values (7788,'SCOTT')
     into emp (empno,ename) values (7839,'KING')
     into emp (empno,ename) values (7844,'TURNER')
     into emp (empno,ename) values (7876,'ADAMS')
     into emp (empno,ename) values (7900,'JAMES')
     into emp (empno,ename) values (7902,'FORD')
     into emp (empno,ename) values (7934,'MILLER')
select * from dual ; --- // Add this statement manually or in the script
