Create batch file containing SQL commands

Question

Hi,
Iam using windows xp... I have 8 *.sql files, all of them contain insert statements and every file takes 40 min to execute and when one finishes i execute the other.
Is there any way that i can combine them and execute at one go..
Now iam using
spool o:\abc.log
@abc.sql
spool off
Can any one help me ..
Any help would be appreciated
Thanks

Insert statements!?
All of them totally trash the Oracle Shared Pool.. If only done properly, each would take mere seconds to run and not 40 minutes.
A snip of a benchmark I posted some time ago showing just how utterly wrong it is to code SQL inserts using literal values.
SQL> create table footab( n number );
Table created.
SQL> set timing on
SQL>
SQL> -- doing a 100,000 inserts using a single SQL INSERT with bind variable
SQL> declare
2 sqlInsert varchar2(1000);
3 begin
4 sqlInsert := 'insert into footab( n ) values( :0 )';
5 for i in 1..100000
6 loop
7 execute immediate sqlInsert using i;
8 end loop;
9 end;
10 /
PL/SQL procedure successfully completed.
Elapsed: 00:00:04.91
SQL> -- doing a 100,000 inserts using a 100,000 SQL INSERTs
SQL> declare
2 sqlInsert varchar2(1000);
3 begin
4 -- need to built a unique SQL for each insert
5 for i in 1..100000
6 loop
7 sqlInsert := 'insert into footab( n ) values( '||i||' )';
8 execute immediate sqlInsert;
9 end loop;
10 end;

SQL>The second method is what you are using. 1000's of insert statements, each with hard coded literal values to insert.
The first method show how it should be done from the client side - using a single SQL insert with bind variables.
And the result? 5 minutes 21 seconds versus a mere 4.91 seconds!!!
You need to seriously rethink your approach. Abusing Oracle is not how one achieve the spectacular performance and scalability that Oracle is famous for.
