Jsp query help

New to jsp, i am trying to write a query which contains a variable, and could use some advice. My code is as follows:
<%
String name = (String)session.getAttribute("logon.isDone");
%>
<sql:query var="queryresults" dataSource="jdbc/poolDB">
SELECT * FROM interests WHERE user_id= (select USER_ID from user_tbl where USER_NAME = ?)
<sql:param value="${name}"/>
</sql:query>
It is my understanding that the ? is replaced by the param value, but it is not working for me.
Thx.

It is my understanding that the ? is replaced by the param value,
but it is not working for me. Your understanding is correct.
Your code looks like it should run (the query is a little funny but ok)
What about it is not working?
Are you getting an error?
Is it displaying the wrong result?
What happens when you run the query against the database specifically?
What happens if you have the query just
select user_id from user_tbl where user_name = ?
does it retrieve/display the correct id?
Nesting queries like this is not normally a good idea. I would work off the user_id rather than the user_name as a parameter to this query, and remove the subquery completely.

It seems I have confused enough people with my improper presentation of query. Sorry guys. I will restate my question with different table names.
The above was my previous posting, which was not clear..so Iam restating my problem as follows....
I have the following tables
Customer(custID, Name, Address)
Order(custID, OrderID, orderDate)
CreditCard(custID, creditCard#, creditCardType)
Now if I have 3 records in Order with custID 100 and 2 records in CreditCard as
Order:
100,A001,11/22/03
100,A002,11/24/03
100,A003,12/02/03
CreditCard:
100,42323232..., VISA
100,5234234...., MASTER
Now how can I get
custID, Name, Address, OrderID, orderDate, creditCard#, creditCarType
data in minimum no. of records....
I think I have made my query clear..
now please help me guys...
thanks so much for your help.

You are right.
But frankly the actual tables on my database are not customer,orders and creditcards..but I just tried to reproduce the problem with these tables, please ignore that user needs a refund etc situtaion. If the tables were actually order,creditcards etc..it would have been a problem to be considered.
Can you please help me with the query
if I have m rows in Order and n rows in CreditCard. I will get m*n records, I looking for max(m,n).
With the following fields in my query result,
custID, Name, Address, OrderID, orderDate, creditCard#, creditCarType
from Customer, Order, CreditCard tables
Thanks so much for your htlp

JSP Query Form

Hello,
I used Jdev 903 wizard to create a JSP Query and Browse Form for a table with many columns. It worked well. However, I want to limit number of columns in the query form, also to break up the columns to be in many section in the display page. I looked into many way; but didn't find anyway. Please help!
Thanks.
Andy.

Once you create the Query-by-Form datawebbean, you can modify the templates in the templates\webapp directory by changing all usages of the FindForm bean to use your new DWB. You can also create a new webapp template by copying the existing file and creating a new directory. You can add you new template by modifying the templates\apptemplates.xml. The current entries are:
<?xml version="1.0"?>
<APPTEMPLATES>
<TEMPLATE NAME="default" DIRECTORY="templates/webapp/" USETHEMESELECTION="YES">
</TEMPLATE>
<TEMPLATE NAME="Oracle" USEFORMSELECTION="NO" DIRECTORY="templates/cabowebapp/" THEMEDIR="/webapp/jsimages" THEMECSS="/webapp/cabo/images/cabo_styles.css" USETHEMESELECTION="NO" TOOLBARCLASS="oracle.jbo.html.databeans.JSNavigatorBar">

SQL Query Help - Is this possible or impossible????

Hi guys,
I need help with an SQL query that I'm trying to develop. It's very easy to explain but when trying to implement it, I'm struggling to achieve the results that I want.....
For example,
I have 2 tables
The first table is:
1) COMPANY create table company (manufacturer varchar2(25),
                                                      date_established date,
                                                      location varchar2(25) );My sample test date is:
insert into company values ('Ford', 1902, 'USA');
insert into company values ('BMW', 1910, 'Germany');
insert into company values ('Tata', 1922, 'India');The second table is:
2) MODELS create table models (manufacturer varchar(25),
                                             model varchar2(25),
                                             price number(10),
                                             year date,
                                             current_production_status varchar2(1) ) ;My sample test data is:
insert into models values ('Ford', 'Mondeo', 10000, 2010, 0);
insert into models values ('Ford', 'Galaxy', 12000,   2008, 0);
insert into models values ('Ford', 'Escort', 10000, 1992, 1);
insert into models values ('BMW', '318', 17500, 2010, 0);
insert into models values ('BMW', '535d', 32000,   2006, 0);
insert into models values ('BMW', 'Z4', 10000, 1992, 0);
insert into models values ('Tata', 'Safari', 4000, 1999, 0);
insert into models values ('Tata', 'Sumo', 5500,   1996, 1);
insert into models values ('Tata', 'Maruti', 3500, 1998, 0);And this is my query:
SELECT
        com.manufacturer,
        com.date_established,
        com.location,
        DECODE(nvl(mod.current_production_status, '0'), '0', '-', mod.model),
        DECODE(nvl(mod.current_production_status, '0'), '0', '-', mod.price),
        DECODE(nvl(mod.current_production_status, '0'), '0', '-', mod.year),
        mod.current_production_status
FROM
       company com,
       models mod
WHERE
      mod.manufacturer = com.manufacturer
      and com.manufacturer IN ('Ford', 'BMW', 'Tata')
      and mod.current_production_status IN (1,0)
ORDER BY
        mod.current_production_status DESCWhat I want the query to output is this:
com.manufacturer        com.date_established          com.location          mod.model          mod.price             mod.year     mod.current_production_status
Ford               1902                    USA               Escort               10000               1992          1
BMW               1910                    Germany               -               -               -          0
Tata               1922                    India               Sumo               5500               1998          1If current_production_status is 1 it means this particular model has been discontinued
If current_production_status is 0 it means the manufacturer does not have any discontinued models and all are in procuction.
The rule is only one record per manufacturer is allowed to have a current_production_status of 1 (so only one model from the selection the manufactuer offers is allowed to be discontinued).
So the query should output the one row where current_production_status is 1 for each manufacturer.
If for a given manufacturer there are no discontinued models and all have a current_production_status of 0 then ouput a SINGLE row that only includes the data from the COMPANY table (as above). The rest of the columns from the MODELS table should be populated with a '-' (hyphen).
My query as it is above will output all the records where current status is 1 or 0 like this
com.manufacturer        com.date_established          com.location          mod.model          mod.price          mod.year     mod.current_production_status

Any ideas how I can achieve the result I need?

Hi Vishnu,
Karthiks query helped...
But this is the problem I am facing...
SELECT
        com.manufacturer,
        com.date_established,
        com.location,
        DECODE(nvl(mod.current_production_status, '0'), '0', '-', mod.model),
        DECODE(nvl(mod.current_production_status, '0'), '0', '-', mod.price),
        DECODE(nvl(mod.current_production_status, '0'), '0', '-', mod.year),
        mod.current_production_status
FROM
       company com,
       models mod
WHERE
      mod.manufacturer = com.manufacturer
      and com.manufacturer = 'Ford'
      and mod.current_production_status IN (1,0)
ORDER BY
        mod.current_production_status DESCThe value of:
and com.manufacturer = 'Ford'will be dependent on front end user input....
When I run the query above I get all the rows where current_production_status is either 1 or 0.
I only require the rows where current_production_status is 1.
So if I amend it to look like this:
     and mod.current_production_status = 1This works....
BUT if a user now passes in more than one manufacturer EG:
and com.manufacturer IN ('Ford', 'BMW')The query will only return the one row for Ford where current_production_status is 1. However because BMW has no models where current_production_status is 1 (all 3 are 0), I still want this to be output - as one row....
So like this:
com.manufacturer        com.date_established          com.location          mod.model          mod.price             mod.year     mod.current_production_status
Ford               1902                    USA               Escort               10000               1992          1
BMW               1910                    Germany               -               -               -          0So (hopefully you understand), I want both cases to be catered for.....whether a user enters one manufacturer or more than one...
Thanks you so much!
This is really driving me insane :-(

Best way to create, modify, XML with JSP ? HELP

Hi friends,
As i am new to XML,
I know there are two APIs used for XML processing, i want to know as a begineer level, which API
is easy and good to implement XML with JSP.
1) SAX
2) DOM
i want to make a log file in XML, so on web page it will be displayed on HTML form through XSL.
Since there is good tutorial on http://www.w3schools.com/dom
but i think its HTML dom
I want XML procession through JAVA CODE , what should i use ? and give some good tutorials on XML DOM
that is used with JAVA / JSP.
HELP.
Edited by: Ghanshyam on Sep 19, 2007 3:24 PM

Well what i think is you gonna checkout with your requirements before implementing any of the popular XML parsing mechnisms.
If you are intrested in faster processing @sacrifising a gud amount of your Memory,DOM is the one which you are looking for.
If you are instrested in Managing your memory and but if you are ok with sacrifising speed SAX is the best solution.it works on what is called a push technology.
and if you think either way you might have to look towards a pull parser which is StAX (Streaming API for XML Parsing)
it'd be a gr8 idea if you can go through the below article which explians about each of the parsing mechanisms
http://www.stylusstudio.com/xml/parser.html#*
coming back to helpful resources as far java is concern checkout the below link which might be of some help.
and the main thing is that all of these parser there is a defined specification you might find implementations of different vendors on this.
eg:Sun Provides one with JDK itself,same as IBM provides one,oracle does the same & so on...
your first task would be to focus on one such implementation which can cater your requirements.

Need a query help

hii
i need a query help
i have two tables
the 1st table will look like this
associate id weekid no.of. hours
4000 810 40
4000 820 30
4000 830 60
4000 840 70
2nd table will look like this
associate id weekid no.of.hours
4000 810 40
4000 820 70
4000 830 130
4000 840 200
so when i subtract the last two records frm each other in the second table the value should be equal to the no.of.hours in the first table.. for example
the query shud consider the last record and one before the last record and the difference between two records shud be equal to the value in the 1st table
for example
consider week id 830 and 840
in second table 830=130
840=200
when u subtraced both values the difference shud be equal to value in the 1st table for tht week id
1 ---->>>> 840 - 830
=200 - 130
=70
in first table 840 has 70 hrs
like this it shud check with all records and it shud return only the records which are not equal

what's wrong with using the page's URL in order to navigate. If you need to go to a particular page, just use it's URL. The BC4J application is already cachin your application's state, it's not necessary to navigate the browser's history.

How to pass variables between 2 jsp pages-help

Hi,
I have a question like this.
As an example consider I have 3 .jsp pages.
page1.jsp - In this html form it has some textboxes to enter employee details.
page2.jsp - In this page it has a "PRINT" button which allows the user to click.
page3.jsp - A new popup window which having the same content as page2.jsp, but without the PRINT button.
But my problem is this. In this page3.jsp,it should be display the entered textbox values as page2.jsp. But these values are not displaying here. They display as NULL.
I use as follows, but it still not working.
<%= request.getParameter("effDate")%>.
Could you please tell me how to hold these values when I came from page2 to page3.
I'm using JSP 1.2 with javaBeans.
Thanks.

Well,
If you are popping up a new window, and you insisting on pulling the data out of the request's parameter map. Then you will need to add the values to the query string of your url.
window.open("http:localhost/page3.jsp?itemOne=itemOneValue&itemTwo=ItemTwoValue, '', '');
Alternative Option:
When posting from page 1 to page two, store your information into session scope
request.getSession().setAttribute("valeuOne", "valueOneValue");
Then instead of pulling from the paramter map, use request.getSession().getAttribute("valueOne") in your third page.
Hope that helps.
Thanx

How to Parse JSP query results to XML Document ???

Hey Guys, I am querying a DB with huge amount of traffic. A user select a particular lot and then details of the lot will be displayed in the following page. My concern here is that it takes really LONG to retrieve back the results coz it has to requiry in the following JSP page.
I was told to use XML to retrieve the dataset and store it. Hence, in the following query it will re-query only from the recordsets in the XML file (...Logically, should be faster rite ? )
My question is how do I go about doing this ? Any sort of suggestion , help, reference would be deeply appreciated ..Thanks !

Why not take the result set and populate zero or more Java objects with data from each row in the result set? Then you can easily sort the data by putting the objects into a collection and using different Comparator objects for your sort. I'm just not sure why you want to use XML if the data isn't getting transfered between systems. In my experience XML is best used when you need a readable content for something (such as a properties file) or you want to share data between systems. I might be missing something, but I think you are better off storing your data in java and sorting it there.

Query help on Goods Receipt Query with AP Invoice

Looking for a little help on a query. I would like to list all the goods receipts for a given date range and then display the AP Invoice information (if its been copied to an AP Invoice). I think my problem is in my where clause, I plagerized an SAP query to show GR and AP from a PO as a start. SBO 2005 SP01. Any help would be great appreciated. Thanks
SELECT distinct 'GR',
D0.DocStatus,
D0.DocNum ,
D0.DocDate,

OR (I1.BaseType=20 AND I1.BaseEntry IN
(SELECT Distinct DocEntry
FROM PDN1 WHERE BaseType=22 AND DocDate>='[%0]' AND DocDate<='[%1]'))

Hi Dalen ,
I believe it is because of the condition
(D1.BaseType=22 AND D1.DocDate>='%0' AND D1.DocDate<='%1')
OR (I1.BaseType=20 AND I1.BaseEntry IN
(SELECT Distinct DocEntry FROM PDN1 WHERE PDN1.BaseType=22 AND DocDate>='%0' AND DocDate<='%1'))
Try changing
D1.BaseType=22 OR D1.DocDate>='%0' AND D1.DocDate<='%1
PDN1.BaseType=22 OR DocDate>='%0' AND DocDate<='%1'))
Lets see what would be the result . Lets have some fun with troubleshooting
See what would be the difference in the result .

Query help: query to return column that represents multiple rows

I have a table with a name and location column. The same name can occur multiple times with any arbitrary location, i.e. duplicates are allowed.
I need a query to find all names that occur in both of two separate locations.
For example,
bob usa
bob mexico
dot mexico
dot europe
hal usa
hal europe
sal usa
sal mexico
The query in question, if given the locations usa and mexico, would return bob and sal.

QUERY HELP!!! trying to create a query

i'm creating a summary report
i have a table with sale dates
for example i have a table tab_1 and column saleDate as
saleDat
1923
1936
1945
2003
2005
saleDate contains years and there are some missing years where no sale
was made
My report has to display years starting from earliest year
so i have to create a query that starts with 1923
but the problem is that I have to have years that are not in table.
for example i have to display years 1924 which is not in table
so the part of report has to look like
1923 blah blah summary.........
1924 "
1925
1926
2005
2006
upto current year (2006 may not be in the table, but i have to display)
i just need to know the query that can query all the years starting from
the ealiest saleDate to current year
thanks in advance

Please write the query in the following form:
SELECT a.year, --- place other columns from your table.
FROM (SELECT (:start_num + rownum) year
FROM all_tab_columns
WHERE :start_num + rownum <= :end_num) a,
tab_1 b
WHERE a.year = b.saleDat(+);
Note:
1) if your start year and end year are 1923 and 2006. Then input as below:
:start_num = 1922
:end_num = 2006
2) Since for some of the years (1924 etc) may not be there in your so you may need to use NVL to print proper indicators.
3) If you have more than one record in tab_1 for a particular year then group them based year and then use it.
Hope this helps.

Pulling open invoices, and paid invoices with details (Query Help).

Hello All,
I am sure I messed something up in my joins. I am looking to pull a report of all invoices OINV for a month, then list details of any payment (if it is paid) next to it from RCT2. It is giving me a list of all of the paid invoices, but even though I have a LEFT JOIN it is not listing any of the invoices without payments.
This is where I am now from the report wizard in Crystal.
SELECT "OINV"."DocNum", "OINV"."SlpCode", "OINV"."CardCode", "OINV"."DocTotal", "OINV"."U_Commission", "OSLP"."SlpName", "RCT2"."DcntSum", "ORCT"."TaxDate", "OINV"."DocEntry", "OINV"."TotalExpns", "OINV"."CANCELED", "ORCT"."Canceled", "ORCT"."DocNum", "RCT2"."InvType"
FROM ("DBName"."dbo"."OINV" "OINV" LEFT OUTER JOIN "DBName"."dbo"."OSLP" "OSLP" ON "OINV"."SlpCode"="OSLP"."SlpCode")
INNER JOIN ("DBName"."dbo"."ORCT" "ORCT" INNER JOIN "DBName"."dbo"."RCT2" "RCT2" ON "ORCT"."DocNum"="RCT2"."DocNum")
ON "OINV"."DocEntry"="RCT2"."DocEntry"
WHERE "OINV"."CANCELED"='N' AND "ORCT"."Canceled"='N' AND "RCT2"."InvType"<=N'14'
ORDER BY "OINV"."SlpCode", "ORCT"."DocNum", "ORCT"."TaxDate"
Thank you in advance for any help you can give me.

Hello Kiran,
I thought about that, but my purposes for running the report is to determine commission based on the date that the invoice was paid, I need the TaxDate in ORCT as it relates to the payment in RCT2.
Removing the ORCT.cancelled condition and the RCT2.invtype conditions now pulls all of the invoices, paid and unpaid. I know now I cant have them in my query, when the record does not exist in ORCT it doesnt have a value for cancelled, and when there is no record in RCT2 there is no invtype, and is filtered.
Maybe I can say where ORCT.Canelled = 'N' OR ORCT.Cancelled = NULL, but I dont know if that would work.

Query Help for reporting on last receipt qty

SBO Version: 8.82 PL11
Hello Forum,
I am looking for some help devising a command behind a crystal report. We are hoping to achieve the last receipt quantity. To arrive at this we would like it to get the last GRPO for an item and total the quantity on that particular GRPO. In addition to this, we want to consider all the lines on the document and SUM them.
At present, the query I have is as follows:
Select SUM(c0.Quantity) from PDN1 c0 WHERE c0.ItemCode = T1.ItemCode AND Shipdate = (select Max(ShipDate) from PDN1 C0 INNER JOIN OPDN c1 ON c0.DocEntry = c1.DocEntry where C0.Itemcode =T1.ItemCode AND c1.DocStatus <> 'C'))
Any assistance would be greatly received.
Thanks
Sarah
