Sql*loader using JSP

wht is the way of using sqlldr in JSP script to load data Oracle DB from a csv file.
i know how we do sqlldr in cmd.
can we provide the sqlldr command to system by using jsp if yes how?

SQL*Loader is a command-line utility. In theory, since Java can call out to the operating system, you could invoke SQL*Loader on the application server to load data into Oracle. It would probably be more appropriate, though, to copy the CSV to the database server and make use of an external table in the database to do the load.

Sql loader using position and functions

Hi all, i need help loading some data in my table using sql loader. consider the following
CREATE TABLE er
a1 NUMBER,
a2 number,
a3 VARCHAR2(100),
a4 VARCHAR2(100),
a5 VARCHAR2(100),
a6 VARCHAR2(100),
a7 VARCHAR2(100),
a8 VARCHAR2(100)
OPTIONS (BINDSIZE=20548000, READSIZE=20548000, STREAMSIZE=20548000, DATE_CACHE=25000, SKIP=0)
LOAD DATA
INTO TABLE er
APPEND
TRAILING NULLCOLS
a1            POSITION(0001:0021)               ,
a2            POSITION(0022:0042)       "DECODE(SUBSTR(:a2,1,3),'***',NULL,:a2)"      ,
a3            POSITION(0043:0053)       ,
a4            POSITION(0054:0064)          ,
a5            POSITION(0065:0075)           ,

                 0.00 ******************** X          X          X          *X          ****
END;if you look at the data, some fields have a lot of * and some has af few such as ****. i want to load this data into a table and when a field contain all * as a value, i want to set it to null. if a field contain a * and alphanumeric then that value should be load as it is.
in the example above, ******************** should be set to null and **** should also be set to null. notice that there is a field with X. since this field contain alpha numeric, it should be loaded into the table as is. the only time field should be set to null is when the value contain all .
somebody in this forum suggest using decode but it looks like it is not working and i get error when it reads second field and try to insert into a2 number column.
is there any way to use regular expression to find out if a field contain all *. also i want to trim each field since they might contain leading spaces.
can some one help with this using the sqlloader ctl and data above?

You can include regular expression in you SQL*Loader control file.
An example can be found here:
http://www.morganslibrary.org/reference/sqlloader.html
Demos 7 and 8 using the UPPER and DECODE functions to illustrate how to do it.

Calling SQL Loader using HOST command from Developer Forms 4.5

I want to execute a set of code from D2K Forms 4.5 which has interfface with Client - OS ( In my case Windows NT/XP). I want to execute SQL Loader from Forms using Host Command and then after completion of that process, I want to do next transcations ( depending upond success of HOST/SQL Loader).
How to achive this?
I tried writing code like this ...
l_vc_command := 'sqlldr73'
                    ||' USERID='||l_vc_username||'/'||l_vc_password||'@'||l_vc_connect_string
                    ||' CONTROL='||l_vc_filepath||'Upload.ctl'

HOST(l_vc_command,NO_PROMPT);
After this command i want to do some other code execution. so even if it fails or success, next code is executed. How to control this?
Please help..

Forms6i running on W2000, Rdbms 8.1.7
in Forms I added a button TEST,
Trigger when-button-pressed : host('test.bat') ;
in directory .......\frm I added file test.bat :
REM ===============
cd /d C:\........\ldr
pause
sqlldr parfile=test.par
pause
type test.log
pause
exit
REM ================
now, pressing TEST button opens DOS window, telling me what's going on, running sqlldr, finally going back to forms
Are you using NO_PROMPT or NO_SCREEN option of HOST command ?
Had a look at Forms 4.5 manuals, there is no mentioning of (a)synchronously operation in connection with HOST command.

Sql loader using sql statement

Hi All ,
May i know any way used sql loader refer sql statement e.g "select a from test"
import data into other table ?
if you have any sample or link , please let me know , thanks a lot

If you are using the database steps, the answer is yes. I've done it by creating a data source that uses the Microsoft Text Driver in the ODBC administrator. The Open Database step is then configured like any other ODBC database. In the .csv file, I have the first line define the column names (i.e. column1, column2) and the SQL statement I use is "SELECT * FROM junk.txt". I haven't tried anything with a WHERE clause but that should work as well.

Executing SQL Loader ----- Using Java & C!!!!!!!!!!!!!

Hello,
We r confirmed that to execute SQL Loader,
One need to write an External Routine.
So First Step itself need to create a
'C' file which executes our sql Loader or
Using Java.
How Can I execute the SQL Loader (.exe)
using Java?
How can I proceed? Waiting ASAP. Thankyou

I have a nice piece of Java code that allows you to execute OS commands from within a PL/SQL block in Oracle. If you need the code send me an email. I know it works in Unix and it should work on most platforms.

SQL Loader: using your own function

Hi,
Is it possible to include your own function in sql*loader? Would this be a correct syntax?
LOAD DATA
APPEND
INTO TABLE MY_TABLE
IDE "my_seq.nextval"
CLIENT_NBR POSITION (1:10) CHAR
CLIENT_TYP POSITION (11:12) "MY_PACKAGE.MY_FUNCTION(:CLIENT_TYP)"
)So the value of the data ( position 11:12) needs te be processed first by the function. The result of the function needs to be stored in the CLIENT_TYP column.
Thank you

How to connect to MS SQL server using JSP?

Hi, i am new to JSP so i would like to know what is the code to create a connection to MS SQL server.
I am using jakarta-tomcat 4 as my server.
sorry for any inconvenient....
pls help me....

This works to start off with but there are more sophisticated/ different ways of doing things,for instance it's best not to access the db via your jsp, rather do this logic in JavaBeans, Servlets or use Struts.Therefore, it's best that you consult with others and find out which is best way to go about creating your web apps.
Here's some code:
In my jsp's I access the bean below , instantiate a statement object and go on from there:
*SOME of the code in the JSP's.
//create bean instance
<jsp:useBean id='dbConn' class='projectsevenhouses.DatabaseConnectionBean ' scope='session' />
//instantiate statement
Statement st = dbConn.getConnection().createStatement();
* JavaBean
package projectsevenhouses;
public class DatabaseConnectionBean implements Serializable {
private Connection conn;
private Statement st;
private String dbURL = "jdbc:odbc:datasource";
private static String driver = "sun.jdbc.odbc.JdbcOdbcDriver";
/** Creates a new instance of DatabaseConnectionBean */
public DatabaseConnectionBean() {
makeConnection();
public void setDatabaseName(String dbName) {
dbURL = dbName;
private void makeConnection() {
try {
Class.forName(driver);
conn = DriverManager.getConnection(dbURL,"sa","");
} catch (SQLException e) {
System.out.println("SQL Cause ->" + e.toString());
} catch (ClassNotFoundException cnf) {
System.out.println("Class Not Found:" + cnf);
public Connection getConnection() {
if (conn == null) {
makeConnection();
return conn;
public void setCloseConnection(boolean close) {
if (close) {
try {
conn.close();
} catch (Exception e) {
conn = null;
Hope it gives u an idea...

SQL*Loader use of sequence

I need to use a loader script to "append into" two tables. The first insert needs to generate a sequence.nextval. I understand how to do this:
LOAD DATA
INFILE 'test.in' "var 2"
APPEND INTO TABLE customerinfo
FIELDS enclosed BY "|"
(CUSTOMERINFOID "customerinfoid_seq.nevtval",)....
Then I need to use that same sequence value to insert into the second table. Can you return the nextval for subsequent use by the loader? Thanks in advance,
Tia

use seqname.CURRVAL to get that same value, but must get it before the next seqname.nextval is used. Maybe you could load a temp table and load the final table with cursor logic (insert table one from nextval, insert table two from currval), OR if the records are of equal number and in exactly the same order, you could chance using a SECOND sequence.

Can we schedule Loader Jobs (SQL Loader) using Grid Control ?

Can we schedule SQL Loaders jobs/process using Grid Control for 11g database ?
Or
Is it good to schedule it as external jobs using DBMS_SCHEDULER ?
OS is LINUX. Database is 11g R1 Grid Control will be the latest, I believe 10gR3.
Any other suggestions... (I know it can be done using OS utilities like cron and others but that is not an option for now.)
Thanks in advance.

Try this
-> Create a shell script to execute sqlldr
-> On Grid, create an "OS COMMAND" job and pass this script as parameters. You'll have options to schedule this job.
Let us know how it works.

Using jsp:include in showOneTab - main form not loaded on submit

I have a JSP page with JSF and ADF components. It is a large JSP containing some main details and then an af:showOneTab component to create a set of tabs. It works fine with JDK 1.5 and Tomcat 5.0 but when changed to Oracle Application Server 9.0.4 and JDK 1.3 We get the following error:
JspCompileException:.... code too large for try statement catch( Throwable e}....
Finding this to be caused by large size of JSP, we divided the page as follows - a main jsp containing the main form details and 1 jsp for each tab. Whenever one of the tabs is clicked the corresponding JSP is dynamically loaded using jsp:include tag as follows:
<af:showDetailItem text="Tab1" id="tab1" styleClass="menu">
          <f:subview id="viewTab1">
               <jsp:include page="Tab1.jsp" />
          </f:subview>
</af:showDetailItem>
There is a Submit button in the main jsp, when this is clicked the main jsp is reloaded.
But when the user navigates to any of the tabs and then clicks the Submit button in the main form, the main form is not reloaded - only the jsp for the currently selected tab is loaded.
(I am using f:view and h:form in the main form, and no form tag in the included jsps)
How to solve this problem?

The af:selectOneChoice components are in the test.jsp page included in main.jsp with jsp:include tag.
The code look like this:
               <af:selectOneChoice label="#{msg.team}"
id="soc1"
value="#{myBean.selectedTeamID}"
autoSubmit="true">
<f:selectItems id="si1" value="#{myBean.teamList}"/>
</af:selectOneChoice>
<af:selectOneChoice label="#{msg.subteam}"
id="soc2"
value="#{myBean.selectedSubteamID}"
partialTriggers="soc1"
rendered="#{myBean.selectedTeamID!=null}"
autoSubmit="true">
<f:selectItems id="si2" value="#{myBean.subteamList}"/>
</af:selectOneChoice>
the code works fine in the seperate page, but when I include the page the second selectOneChoice component doesnt get rendered.
