Using SQL Loader in a procedure

Question

Can we use SQL Loader in a stored procedure to load data in an Excel file into the database? If so, how. Also, how can it create a log file to save records that have not been loaded.

Answer 1

You can..Try this out..
CREATE OR REPLACE AND COMPILE JAVA SOURCE NAMED "Host" AS
import java.io.*;
public class Host {
public static void executeCommand(String command) {
try {
String[] finalCommand;
finalCommand = new String[4];
finalCommand[0] = "C:\\windows\\system32\\cmd.exe";
finalCommand[1] = "/y";
finalCommand[2] = "/c";
finalCommand[3] = command;
final Process pr = Runtime.getRuntime().exec(finalCommand);
new Thread(new Runnable() {
public void run() {
try {
BufferedReader br_in = new BufferedReader(new InputStreamReader(pr.getInputStream()));
String buff = null;
while ((buff = br_in.readLine()) != null) {
System.out.println("Process out :" + buff);
try {Thread.sleep(100); } catch(Exception e) {}
catch (IOException ioe) {
System.out.println("Exception caught printing process output.");
ioe.printStackTrace();
}).start();
new Thread(new Runnable() {
public void run() {
try {
BufferedReader br_err = new BufferedReader(new InputStreamReader(pr.getErrorStream()));
String buff = null;
while ((buff = br_err.readLine()) != null) {
System.out.println("Process err :" + buff);
try {Thread.sleep(100); } catch(Exception e) {}
catch (IOException ioe) {
System.out.println("Exception caught printing process error.");
ioe.printStackTrace();
}).start();
catch (Exception ex) {
System.out.println(ex.getLocalizedMessage());
public static boolean isWindows() {
if (System.getProperty("os.name").toLowerCase().indexOf("windows") != -1)
return true;
else
return false;
show errors java source "Host"
And now create an Oracle wrapper
SQL>
CREATE OR REPLACE PROCEDURE Host_Command (p_command IN VARCHAR2)
AS LANGUAGE JAVA
NAME 'Host.executeCommand (java.lang.String)';
Procedure created.
Now invoke the procedure with an operating system command
BEGIN
Host_Command (p_command => 'sqlldr system/tiburon@"(DESCRIPTION\=(ADDRESS_LIST\=(ADDRESS\=(PROTOCOL\=TCP)(HOST\=ICCW3053)(Port\=1521)))(CONNECT_DATA\=(SERVICE_NAME\=orcl)))" control=C:\anupama\emp_join.ctl log=C:\anupama\emp_join.log');
END;
/Let me know if it works\encounter any troubles.
Good luck!!!
