JDBC Query

Hi All,
Could you please tell me if we can have multiple select, insert, delete etc quesry's in one database fetch using JDBC adapter.
Is multiple UPDATE commands possible.
Also why is update command used??
Regards,
Ashish

Ashsih,
Sure we can do everything in one shot.
For the receievr JDBC adapter , the datatype that you create matters a lot.
If you look into <a href="http://help.sap.com/saphelp_nw04/helpdata/en/2e/96fd3f2d14e869e10000000a155106/content.htm">this</a> link and see the datatype, you have multiple STATEMENT tags and each of these perfroms a separate function like Insert, Update , Delete etc. So, you can do all these function using a JDBC receiver adapter in one shot or in multiple calls as per requirement.
Multiple UPDATE is also possible. Update command as the name implies is used to Update the database with some values for rows satisfying some condition.
Please look into these blogs on Receiver JDBC adapter,
<a href="/people/sap.user72/blog/2005/06/01/file-to-jdbc-adapter-using-sap-xi-30">FILE to JDBC Adapter using SAP XI 3.0</a>

For the more clarification, I have used JDBC Query as Data source type and Database connected via ODBC Driver in System DSN. The Driver selected from the drop-downs are jdbc-odbc.
Kindly explain the mistake I m doing.

How to use a jdbc query result to redirect to a variable html page

uh, my problem is that i'm making a servlet which should redirect to a variable html page based on jdbc query (I'm really sorry if this is not the correct forum to post it, but since it's jdbc i thought it was).
Anyway, the problem is that when a string say, "mystring" is equal to the value in a column, say "column1" of the database then page should redirect to "mystring.html".
Is this possible, if so then how?
and if not then is there any other way to solve my problem?
please, help!!
thanks in advance.

uh, since i've already asked man, please gimme an answer if you know, it'll be appreciated.
OK, HERE'RE THE DETAILS:(as you requested them)
i have an html page where there's a textfield say "t1", the value of that text field is sent to the servlet which compares the value of the field with the value in Database, say "db1" in column say "column1".
if there's a value in the column matching the value inputted in the textfield, then i need the servlet to redirect to an html page of the same name as inputted in the textfield. Hope that helps you understand.....
thanks in advance.......

JDBC query theme in a JSP page

Hi, everyone
I tried to write JDBC query theme in a JSP page at MapViewer, but it did not work.
The following is the codes.
1.JDBC theme in a map request in XML
<theme name="jdbc_theme_contour">
<jdbc_query
datasource="spatial10g"
jdbc_srid="8703"
spatial_column="geom"
render_style="C.RED">
Select geom from contour where time='01-JUL-07'
</jdbc_query>
</theme>
2. JDBC theme in a JSP request.
"<theme name=\"jdbc_theme_contour\" >\n" +
" <jdbc_query \n" +
" jdbc_srid=\"" + srid + "\"\n" +
" datasource=\"" + dataSource + "\"\n" +
" spatial_column=\" geom \"\n" +
" render_style=\"C.RED\" >\n" +
" SELECT geom from contour where time='01-JUL-07' \n" +
" </jdbc_query> \n" +
" </theme> \n" +
I do not know whether the second form is right or not. I did not display the JDBC query in MapViewer. Does anyone know the second form is right? or Maybe give me a right form in a JSP request. (contour is a table , geom is the column of geometry attribute in contour)

JDBC query in the course of a separate EJB transaction

Hi all,
I am implementing a web application that let user upload file and send it to the backend for processing,which involves EJB level transaction(many read+write operations),say transaction L .The processing time may last for 10 minutes. Meanwhile the user can view the history of the files he uploaded and CURRENT STATUS of the file he submitted for processing,we call it file upload history summary (they are from direct JDBC query to the upload history table,say table U in the database,since they are read only data).
My problem is: the user can not see his LATEST file upload status UNTIL the backend processing transaction is completed,although the row for latest file he just submits in Table U was created during the course of the transaction L by an EntityBean UEJB.
I am using Jboss server,do u guys have any idea so that I can see the new file status once it's created by the UEJB even before the transaction L is completed?Thanks

You can achieve this by using JMS and MDB. Because once your file is uploaded, the server is busy in loading the data to the database. So it is not sending you back the response as you are doing a synchronous communication. You have to use Asynchronuous communication to achieve this. This way the client will not wait for the response and the transaction to finish.
While uploading you a send the file as a message object using JMS and MDB. Let the MDB call the other EJB to load the data to the database. Then you can refresh the status browser automatically in certain periods to retrieve data using other EJB like simple access. The browser will automatically submit itself and get the data from EJB while the other EJB uploading the data to the database.
Hope this helps. If you are still not clear write again. I will explain it again.
Thanks

Hi Sachin,
I too, got through the issue. Sorry am bit late in updating you. But still I would say it is not on consistent(my feedback as per I grabbed from the behavior. Say, I accepted the query in a particular order of WHERE clause, then If I change the order it will throw an error message saying "Incorrect syntax".)
Anyway working fine. Thanks for your immediate response with useful hints.

Anand
Hi Anand,
Yes, JDBCPDS accepts all Select queries which follows SQL Specification.
It would be a valid query as per the database used.
Please try again, Bind parameters can be placed in any or all of the conditions of SQL Query in JDBCPDS.
I am able to use them in both the cases you told.

JDBC Query using PL/SQL

I have gotten this to work in my Reports class but can not get this to work at my company. Basically I'm trying to use the JDBC query in Report Builder.
Here is my Ref Cursor Code:
CREATE OR REPLACE PACKAGE SCOTT.types is
type sqlcur is REF cursor;
end;
Here is my Pl/SQL function:
CREATE OR REPLACE FUNCTION SCOTT.test return Scott.types.sqlcur is
c1 Scott.types.sqlcur;
begin
open c1 for select * from scott.emp;
return c1;
end;
I can get this to work in SQL Plus by doing the following:
var r refcursor
exec :r := test;
print r When I go into Reports Builder->JDBC query I connect to the SCOTT db using tiger as the password. I type in the function name TEST and get the error "wrong number or types of arguments in call TEST". I have tried "call TEST" but that doesnt work either. If I use "call TEST" I get an error saying it expected characters ":=(@" etc....
I know my connection works because I can do a "select * from emp" and get results. Can anyone get this to work?
I'm running Report Builder 9.0.2.0.3
I have done multiple searches on this issue and most responses point someone to links that dont work or documentation. I have read them and my code above should work but doesnt........Please put some real examples or code that works with the "Scott" schema.
Thanks

hi Shawn
When running jdbc quesry based on SP with Oracle DB, the first parameter of the store procedure should be of ref cursor type and it shall be a OUT parameter.
For example:
CREATE OR REPLACE PACKAGE jdbcpdspkg AS
TYPE Empcur IS ref cursor ;
procedure proc_with_param (p_emp_cv out jdbcpdspkg .empcur, p1 in number, p2 in number , p3 in number, p4 in number , p5 in number) ;
Thanks

JDBC Query Single Row service Parse Query

Using JDBC Query Single Row service on an Oracle database,
I specify a SQL statement like this:
select abc, to_char(aDate, 'MM/DD/YYYY') from xyz where def = 123
then I click the "Parse Query" button to try to map the query results to my variables, but the mapping window gives me 3 fields instead of 2:
1. abc
2. to_char(aDate)
3. 'MM/DD/YYYY'
how do I let it understand that there are only 2 fields in the results so that I can map it properly?
thanks

Got a new minor issue unrelated to the above, but I don't want to flood this forum with another new topic, so I'll stick this new thing here.
I have a very simple process that only contains this JDBC Query Single Row service.
In this query single row service, at the bottom of the property sheet, there's a section where it says "number of rows retrieved"...
now, if I map this 'number of rows' to a variable (I set the variable's type as "int"), when I call my process (as a web service), it returns me nothing... all the output parameters are empty.
If I remove the mapping of "number of rows", that is, there's nothing in that bottom section. Then my process works correctly, all the output variables contain correct data from my database.
Has anybody encountered this? what's your solution please?

Reports 9i Jdbc Query dialog box

Hi,
Is it possible to base a report on a pl/sql stored procedure in Reports builder 9i environment using with jdbcpds.If possiblePlease provide step by step details and how we can call that particular procedure in JDBC query dailog box.
Please provide detailed example program asap.
Thanks&Regards,
Raghu

Hi Raghu
Indeed yes. You can base your report on PL/SQL stored procedure. For this to work with JDBC query, your stored procedure must return records.
Refer Reports help on OTN for more information.

Rookie...can't return results from JDBC query?

I am trying to get my web service to return results to the client from my JDBC query. They "try/catch statements sem to be in the way. I can't return anything within them or outside of them. Can someone tell me how I could get my results to return to where I want them to?
At present, all this does is return the value "Dummy" to my client. Shouldn't the value be reset by the results of the query coming in?
package hello;
import java.sql.*;
public class HelloImpl implements HelloIF {
String s2 = "Dummy";
public String sayHello(String s) {
try {
Class.forName("oracle.jdbc.driver.OracleDriver");
catch( Exception e ) {
System.out.println("Failed to load driver.");
try {
Connection conn = DriverManager.getConnection("jdbc:oracle:thin:liggy11/fisher@dligman:1521:dligman");
Statement stmt = conn.createStatement();
String query = "SELECT end_phrase FROM rap_lines WHERE start_phrase = '" + s + "'";
ResultSet rs = stmt.executeQuery(query) ;
while (rs.next()) {
s2 = rs.getString("end_phrase");
System.out.println("Got another row. s2 is now [" + s2 + "]");
catch( Exception e ) {
e.printStackTrace();
return new String(s2);

JDBC query hangs server

I have a very weird case when a particular JDBC query kills weblogic server. Attached
is a thread dump. What's weird is:
1. There is only one client on the system, and I sware the client sends only one
request. At the same time there are 12 threads trying to execute the same query.
2. The query is at the start of thread dump and it takes ~9sec to execute on our
DB from SQL+. It returns ~300 records. If I change parameters it will be executed
fine. Each time a client wants to execute a query before it is executed it is
dumped to log, and there is only one query per all threads in the dump.
3. Looking into DB log there is no sight of the query that is dumped into log
file. DB does not have a clue... Both DB and WLS are waiting for each other...
Environment:
6.1sp2 on solaris
Oracle 8.1.7
JDBC driver from Oracle 9i
[x.txt]

There were two problems: request got hanging in the database (original) with proxy
timing out and making situation worse (sending more requests). 9.2.0.1 did not
have the original problem (statement did not hang), but the price was too high
(data corruption) :( Also the problem was very touchy - we got only two environments
which were duplicating it. This last mail was more on the whining side - hope
that someone seen something similar and can say a-ha! So I guess I'm back in slow
and painful try to reproduce and then fix mode... Most likely it all will end
up with SQL tuning, not app level solution...

AFAIR the poblem was not in the driver but in the load balancer

Unfortunately the story is not completely over.
We found that the new driver in some cases garbles the data. That happenson updates
when WLS is changing object and the first parameter in the updatestatement is
string. Sounds weird, so here more details:
- We found that some strings in the database are garbled.
- JDBC trace brought us to update statements. It looks like for eachupdate container
creates prepared statement and sets parameters on it.
- If the first parameter is a string then it will be garbled (happenswith
two
independant objects).
The problem is defenitely driver-specific. It does not show up withany
driver
but 9.2.0.1. All previous drivers work right, but 9.0.1 that we usedbefore had
the problem described in the thread, and 8.x work at least 10 timesslower
(no
kidding).
Test app which connects to the same oracle instance and executes thestatement
from JDBC log works fine (sure it does). Adding nls_charset to classpathdoes
not make any difference. Attempt to create statement from within WLSwas
not taken.
Solution was even more bizzare. Since it was happening only when thefirst
attribute
was string we shuffled attributes and the problem went away. But Ido not
believe
that is a solution - IMHO that just masks the problem.
Any and all brignt and not-so-much ideas are welcome.

JDBC Querying Null Values

I'm using the JDBC Query Multiple Rows as XML to query an Oracle database. Many of the fields I'm querying are nullable and in fact some contain null values. I can't figure out why the JDBC component queries a null value as the string "null". I've tried to work with nvl() or replace() in my SQL statement, but I haven't got either of them to work.
I would assume someone else has run into this. Anyone have any advice on how to get around this?

I just found a solution that worked for my situation.
On the form being merged with the xml data, select the field(s) you want to hide the null value for.
Then go into the 'Field' tab in the 'Object' palette, click on the patterns button.
In the Data tab click 'Allow empty' and in the text box below it type
null
This should hide any null values from being displayed as 'null' on the form. This also works for numeric fields and date/time fields.

driver. I have a JavaServer Pages application that needs to read a VARRAY
from a table and then use the contents of the VARRAY. Here's the code in
the JSP that does that:
resultset=db.executeQuery
("SELECT IMAGE_lIST FROM PAGE_IMAGE_ARRAY WHERE PAGENAME = " +
pagename);
oracle.sql.ARRAY array =
((oracle.jdbc.driver.OracleResultSet)resultset).getARRAY(1);
imageList = (String[])array.getArray();
for(int count=0; count<imageList.length; count++)
out.println("<p>The image at position " + count + " in the array is
the image titled: " + imageList[count]);
The JSP compiles and runs fine, but the output is as follows:
The image at position 0 in the array is the image titled: 0x7465737431
The image at position 1 in the array is the image titled: 0x7465737432
The image at position 2 in the array is the image titled: 0x7465737433
The image at position 3 in the array is the image titled: 0x7465737436
A query using SQL*Plus verifies that the actual values of the elements of
the array are 'test1', 'test2', 'test3', 'test6'. Notice that the last
digit in the hex(?) output matches the last digit of the actual string.
What's causing this? It looks like a data type mismatch, but I would have
thought that such an error would have triggered a compile-time error.
Any help is greatly appreciated.

Dave,
The following should help.
1 select rawtohex('test1') val1,
2 rawtohex('test2') val2
3* from dual
SQL> /
VAL1 VAL2
7465737431 7465737432
SQL> select rawtohex('1') val1,
2 rawtohex('2') val2
3 from dual;
VA VA
31 32
