Running sql commands from a .sql file

Hello , I have this problem. How do i execute sql commands found in a .sql file with jdbc. My RDBMS is mysql.

You will have to open and parse the .sql file, connect to the database, and execute the statements. You can't simply tell JDBC to run your .sql file.
Depending on the complexity of your .sql file this is easy or hard. If its a bunch of e.g. updates or deletes or something you may be able to get away with running it as a block. In Oracle for example, you can put "begin" and "end;" around a bunch of statements and run it all together. In that case your program would open the SQL file, read the text, put it inside a "begin" and "end;", and run it as a single SQL statement.
If its a bunch of statements that must be run independently then you'll have to programatically split them up to run one at a time. If its a select and you want to e.g. print results to the screen, well, then it gets tougher...

How to run OS commands from PL/SQL???

Hi
Is there any way to run OS commands(Windows Platform) from within PL/SQL?
Thanks

APC,
I am working on Discoverer, having lots of BAs & Workbooks created & stored in Database. Now if i want to move all the workbooks from one place to another (like from development to test or production) i can use Command line interface of Disco to do this. But i don't see any option there to export all the workbooks, so i thought of writing a pl/sql to get all the workbook names from the EUL then fire export Command for each record(although not a good practice but its a one time work). This is the place where i need to run OS command from within PL/SQL. Although it doesn't seem possible now(as you all said) without external procedure.
Lastly, you are right that "Oracle make databases not operating systems" but my first impression/comment about oracle is:
"Oracle is far Bigger, Powerful, Complex, Vast and Interesting System than any other..." so i believe it can do/capable doing anything :-)
thx Ashutosh,
Host is definitely an option but i can't run it from pl/sql(that i am looking for)..

Run OS command from Pl/SQL

Is there any way to execute an OS command from pl/sql other than using dbms_pipe & pro*C combo. I have done this way before but it seems there is built-in oracle package which can do this in 8/8i.
Also HOST command in forms will execute the OS coomand from the clinet. Is there any way to execute the OS command on the server from the forms clinet?
thanks,

Running linux commands from pl/sql

Hi, I'm using a java class to run os commands but it doesn't work, i think it's permissions but i cant understand why.
the java class is the following:
import java.io.*;
import java.lang.*;
public class RunCmd extends Object{
public static int RunThis(String args){
Runtime rt = Runtime.getRuntime();
int rc = -1;
try{
Process p = rt.exec(args);
int bufSize = 4096;
BufferedInputStream bis =
new BufferedInputStream(p.getInputStream(), bufSize);
int len;
byte buffer[] = new byte[bufSize];
while ((len = bis.read(buffer, 0, bufSize)) != -1)
System.out.write(buffer, 0, len);
rc = p.waitFor();
catch (Exception e)
e.printStackTrace();
rc = -1;
finally
return rc;
the pl/sql function i created:
function run_cmd(p_cmd in varchar2) return number as language java name 'RunCmd.RunThis(java.lang.String) return oracle.sql.NUMBER';
i gave the following permissions:
begin
dbms_java.grant_permission(user, 'SYS:java.io.FilePermission', '/home/mails/*', 'execute');
dbms_java.grant_permission(user, 'SYS:java.io.FilePermission', '/home/mails/*', 'write');
dbms_java.grant_permission(user, 'SYS:java.io.FilePermission', '/home/mails/*', 'read');
dbms_java.grant_permission(user, 'SYS:java.io.FilePermission', '/home/mails/*', 'delete');
dbms_java.grant_permission(user, 'SYS:java.lang.RuntimePermission', '*', 'readFileDescriptor');
dbms_java.grant_permission(user, 'SYS:java.lang.RuntimePermission', '*', 'writeFileDescriptor');
Dbms_Java.grant_Permission(user, 'SYS:java.lang.RuntimePermission', 'readFileDescriptor', '');
Dbms_Java.grant_Permission(user, 'SYS:java.lang.RuntimePermission', 'writeFileDescriptor', '');
dbms_java.grant_permission(user, 'java.io.FilePermission', '/home/mails/*', 'execute');
dbms_java.grant_permission(user, 'java.io.FilePermission', '/home/mails/*', 'write');
dbms_java.grant_permission(user, 'java.io.FilePermission', '/home/mails/*', 'read');
dbms_java.grant_permission(user, 'java.io.FilePermission', '/home/mails/*', 'delete');
dbms_java.grant_permission(user, 'java.lang.RuntimePermission', '*', 'readFileDescriptor');
dbms_java.grant_permission(user, 'java.lang.RuntimePermission', '*', 'writeFileDescriptor' );
Dbms_Java.grant_Permission(user, 'java.lang.RuntimePermission', 'readFileDescriptor', '');
Dbms_Java.grant_Permission(user, 'java.lang.RuntimePermission', 'writeFileDescriptor', '');
commit;
end;
The command i'm trying to execute is:
select run_cmd('/bin/sh -c "ls -ltr /home/mails> /home/mails/teste.txt"') from dual;
i gave chmod 777 /home/mails and i already run this command directly in console mode and works just fine, so i dont think it's permissions related to the user oracle.
when i run
select run_cmd('/bin/sh -c "ls -ltr /home/mails> /home/mails/teste.txt"') from dual;
it returns 2
if i run
select run_cmd('/bin/sh -c ls -ltr /home/mails> /home/mails/teste.txt') from dual;
it returns 127
if i run just
select run_cmd('ls -ltr /home/mails> /home/mails/teste.txt') from dual;
it returns -1
if anyone as any clue please, i'm trying to solve this problem for 2 days and i don't have any clue for the solution...

when i remove the /bin/sh -c it returns -1
i think that it runs the command because there is a diference in the return value from a valid command a an invalid, for example:
if i run a valid command
select k_cs_controlo.run_cmd('/bin/sh -c "ls -ltr /home/mails > /home/mails/teste.txt"') from dual;
it retuns 2
if i run an invalid command(removed the " between the ls command)
select k_cs_controlo.run_cmd('/bin/sh -c ls -ltr /home/mails > /home/mails/teste.txt') from dual
it returns 127
thanks for the replies Sven

Running OS command from PL/SQL

Hi All,
Is there any way of running a Operating System command thru the PL/SQL Procedure. I am using oracle on the Unix Platform. Do help me.
Thanks In advance,
Nitin Jain

As one who did it, here's what I recommend.
declare
cmdstr varchar2(200); -- this is to compose the OS command to run
begin
-- then you should have something like this
cmdstr:=...;
cmdstr:=cmdstr| |...;
host(cmdstr); -- this actually runs the command held in the cmdstr varchar
end;
Beware: you must be certain which OS you have to deal with, for some procs may be run on UNIX machines as well as on WINDOZE!

Running OS Command from PL/SQL: ORA-29532

Hello All,
I have created a java program, loaded into database using loadjava utility and finally gave grant on execute to public. Then made a wrapper function to call it inside as below:
   FUNCTION fn_OSCommand_Execute (command IN STRING)
      RETURN NUMBER
   IS
      LANGUAGE JAVA
      NAME 'OSCommand.Execute(java.lang.String) return java.lang.int';
Logged into SYS and gave the following gants to SCOTT using dbms_java
declare
v_key NUMBER;
begin
DBMS_JAVA.GRANT_PERMISSION('SCOTT', 'SYS:java.io.FilePermission', '<<ALL_FILES>>', 'read,write,execute,delete',v_key);
DBMS_JAVA.GRANT_PERMISSION('SCOTT', 'SYS:java.lang.RuntimePermission', 'readFileDescriptor', '',v_key);
DBMS_JAVA.GRANT_PERMISSION('SCOTT', 'SYS:java.lang.RuntimePermission', 'writeFileDescriptor', '',v_key);
dbms_java.grant_permission( 'SCOTT', 'SYS:java.io.FilePermission', 'c:\windows\system32\cmd.exe', 'execute',v_key);
COMMIT;
end;
When I am calling the function, I am getting the below error:
ORA-29532: Java call terminated by uncaught Java exception: java.security.AccessControlException: the Permission (java.io.FilePermission c:\windows\system32\cmd.exe execute) has not been granted to SCOTT. The PL/SQL to grant this is dbms_java.grant_permission( 'SCOTT', 'SYS:java.io.FilePermission', 'c:\windows\system32\cmd.exe', 'execute' )
I am running on Windows7 Platform & Oracle 12c 64bit version.
Waiting for all of your expert advice.

Yes my Oracle server is installed on Windows 7.
Actually the user (SCOTT) was missing soome Network ACLs. I got it resolved by giving the connect, resolve network acls for the required host as below:
BEGIN

Using 10g SQL Plus from a batch file

I installed the Oracle Database 10g Express Client and configured my ODBC and tnsnames.ora settings, and I think I have it all right, because when I open the SQL Command Line I can connect to the database just fine using:
connect <username>/<password>@<database>
However, when I try to log in through a non-SQL command line or batch file using the syntax:
sqlplus <username>/<password>@<database>
I get the error "ORA-12154: TNS:could not resolve the connect identifier specified." That syntax used to work for me with 9.2. Does the functionality still exist in 10.2?
Update #1:
The sqlplus login works from a normal command widow if I first CD C:\XEClient\bin. I still can't get it to work from a batch file, even when I specify the path. Does this mean the batch file command can't find my tnsnames.ora? If so, what environment variable do I need to set? I already have the client directory in the Path and ORACLE_HOME variables.
Update #2:
I started randomly trying every Oracle environment variable I could find a reference to, and found that setting TNS_ADMIN to the C:\XEClient\bin directory worked.
I don't need any responses to this post, so it can be deleted by an admin.

Hi Toni,
It is my first post here and I though telepathy already operated here :)
it is Oracle 9 I am talking about.
actually, I have 2 batch files
File 1, lets say the file name is batch1.bat and the contents are
sqlldr user/pwd@tnsname control='Control.ctl' data='data.txt'
File 2, batch2.bat and the contents are
Batch1.bat
Sqlplus user/pwd@tnsname @callproc.sql
Now if I run Batch2.bat, then only the first line to be executed which calling the batch1.bat , the second line (sqlplus) never executed!

How to load SQL scripts from a text file.

Hi, i tried several time to load a text file/SQL script with 10 different tables and data, but 10g Express doesen't allows me to do that, any one can direct me or point out to me what i should do or do i need to adopt any special method to to get this done. i am sure there must be some thing where you can upload SQL scripts from a text file (in SQL command editor!). thanks

Hi,
see my other answer here:
SQL command editor doesn't take more than 1 insert command
This seems to be a duplicate question, right? Or am I missing something?

Process management at the OS level should prevent execution continuing in the calling code until the command has completed (either successfully or with error).
If the low level java code were to spawn child process threads then execution could continue, but I'm guessing the Java function your talking about doesn't do that and just calls the operating system to execute the command and waits for the returning code to come back.
