Multiple Results from Table

Hello,
my EJB Query hast multiple Results.
My Table:
key | value
01 | test1
02 | test2
My Selection:
select Object(b) from PhoneBookEntityBean b
What kind of result type must the finder method have and how can i handle it?
Thanks for help and ideas,
André

Hi
I'm having problem with my finder method also...
I have a finder with name findByEmpName in which I pass string empname as parameter, for this I have put following in my ejb-jar.xml:
     <query>
          <query-method>
               <method-name>findByEmpName</method-name>
               <method-params>
                    <method-param>java.lang.String</method-param>
               </method-params>
          </query-method>
          <ejb-ql>select object(b) from TestEntityBean b where b.empName like ?1</ejb-ql>
     </query>
and inside persistent.xml
     <finder-descriptor>
          <method-name>findByEmpName</method-name>
          <method-params>
               <method-param>java.lang.String</method-param>
          </method-params>
          <load-selected-objects/>
     </finder-descriptor>
but when I use this finder method in my jsp, it return me null (no rows) but corresponding row is present in the database, findByPrimaryKey and create are working fine...
Is any other setting need to be done?? pls help!!

How to retrieve multiple data from table and represent it in jsp page

Hi
The below JavaScript code is used to add row in the table when I want to add multiple row data into table for single entry no field.
<html> function addRow()
            i++;
            var newRow = document.all("tblGrid").insertRow();
            var oCell = newRow.insertCell();
            oCell.innerHTML = "<input name='srno"+i+"' type='text' id='srno"+i+"' size=10>";
            oCell = newRow.insertCell();

            oCell = newRow.insertCell();
            oCell.innerHTML = "<input type='button' value='Delete' onclick='removeRow(this);' />";
           // oCell = newRow.insertCell();
           // oCell.innerHTML = "<input type='button' value='Clear' onclick='clearRow(this);' />";
        }<html> Then this data are send to the next Servlet for adding into two table.
My header portion data are added into one table which added only one row in table. while footer section data are added into the no of rows in another table dependent on No. of
Rows added into jsp page.
Here is an code for that logic.

Too much code. It's also not well intented nor formatted. I don't see a question either or it got lost in that heap of unformatted code.
I will only answer the question in the thread's subject:

I cannot delete multiple entries from table

Hi
i am trying to delete multiple entries from table while keeping some data.
for example I have the following table
Plant                            Item
US101                         777
US101                         888
US101                         999
US101                         666
I want to keep the rows where the item is 777 and 888 for plant US101 and keep delete the rest data
I wrote the following code
Delete source_package where Plant = 'US101' and Item NE '777' or '888'.
but all the rows get deleted.
I tried deleting single row and it worked.
Delete source_package where Plant = 'US101' and Item NE '777' .
How can I delete multiple rows.
thanks

Hi Bhat Vaidya,
Plz refer the following code.. IT will solve ur problem..
REPORT ZSDN_TEST.
data: BEGIN OF it_data OCCURS 10,
        plant(4),
        item_num TYPE string,
      END OF it_data.
data: str type string.
data: it_final like it_data OCCURS 10 WITH HEADER LINE.
it_data-plant = 'US01'. it_Data-item_num = 777. append it_data.
it_data-plant = 'US01'. it_Data-item_num = 888. append it_data.
it_data-plant = 'US01'. it_Data-item_num = 999. append it_data.
it_data-plant = 'US01'. it_Data-item_num = 666. append it_data.
delete it_data where plant = 'US01' and item_num ne 777 and item_num ne 888.
LOOP AT it_data.
write:it_data-plant,it_data-item_num.
skip.
ENDLOOP.

Can I have multiple graphs from tables of multiple reports?

Hi!
I want to design a custom dashboard that contains multiple graphs but these graphs are coming from tables of multiple reports. It is like displaying multiple graphs that are coming from different tables. Is this possible? How?
Thanks.

Hi
*Play all resp one chapter at a time*
Play All Button
1. There are NO - Play All - button in any version of iDVD
2. It can be faked in several ways
• Easies and most fault proof way is to make a doublet movie containing All and with
Chapters set to match. It will take up x2 space but is easy to understand and produce.
• It's said that one can put all movies into a Photo/SlideShow and this will also
give the function of a Play All button - Never tested though.
Mike Evangelist1
You might be able to get close to what you want by using a slideshow in iDVD. (It's not widely known, but you can put videos in a slideshow.) If you set the slide duration to manual, playback will pause after each movie/slide, and you can continue with the 'next' button.
3. Using another program to do this eg. Roxio Toast™ where there ia a Play All button option.

Problem Obtaining multiple results from MySql Stored Proc via JDBC

I've spent alot of time on this and I'd be really grateful for anyones help please!
I have written a java class to execute a MySQL stored procedure that does an UPDATE and then a SELECT. I want to handle the resultset from the SELECT AND get a count of the number of rows updated by the UPDATE. Even though several rows get updated by the stored proc, getUpdateCount() returns zero.
It's like following the UPDATE with a SELECT causes the updatecount info to be lost. I tried it in reverse: SELECT first and UPDATE last and it works properly. I can get the resultset and the updatecount.
My Stored Procedure:
delimiter $$ CREATE PROCEDURE multiRS( IN drugId int, IN drugPrice decimal(8,2) ) BEGIN UPDATE drugs SET DRUG_PRICE = drugPrice WHERE DRUG_ID > drugId; SELECT DRUG_ID, DRUG_NAME, DRUG_PRICE FROM Drugs where DRUG_ID > 7 ORDER BY DRUG_ID ASC; END $$
In my program (below) callablestatement.execute() returns TRUE even though the first thing I do in my stored proc is an UPDATE not a SELECT. Is this at odds with the JDBC 2 API? Shouldn't it return false since the first "result" returned is NOT a resultset but an updatecount? Does JDBC return any resultsets first by default, even if INSERTS, UPDATES happened in the stored proc before the SELECTs??
Excerpt of my Java Class:
// Create CallableStatement CallableStatement cs = con.prepareCall("CALL multiRS(?,?)"); // Register input parameters ........ // Execute the Stored Proc boolean getResultSetNow = cs.execute(); int updateCount = -1; System.out.println("getResultSetNow: " +getResultSetNow); while (true) { if (getResultSetNow) { ResultSet rs = cs.getResultSet(); while (rs.next()) { // fully process result set before calling getMoreResults() again! System.out.println(rs.getInt("DRUG_ID") +", "+rs.getString("DRUG_NAME") +", "+rs.getBigDecimal("DRUG_PRICE")); } rs.close(); } else { updateCount = cs.getUpdateCount(); if (updateCount != -1) { // it's a valid update count System.out.println("Reporting an update count of " +updateCount); } } if ((!getResultSetNow) && (updateCount == -1)) break; // done with loop, finished all the returns getResultSetNow = cs.getMoreResults(); }
The output of running the program at command line:
getResultSetNow: true 28, Apple, 127.00 35, Orange, 127.00 36, Bananna, 127.00 37, Berry, 127.00 Reporting an update count of 0
During my testing I have noticed:
1. According to the Java documentation execute() returns true if the first result is a ResultSet object; false if the first result is an update count or there is no result. In my java class callablestatement.execute() will return TRUE if in the stored proc the UPDATE is done first and then the SELECT last or vica versa.
2. My java class (above) is coded to loop through all results returned from the stored proc in succession. Running this class shows that any resultsets are returned first and then update counts last regardless of the order in which they appear in the stored proc. Maybe there is nothing unusual here, it may be that Java is designed to return any Resultsets first by default even if they didn't happen first in the stored procedure?
3. In my stored procedure, if the UPDATE happens last then callablestatement.getUpdateCount() will return the correct number of updated rows.
4. If the UPDATE is followed by a SELECT (see above) then callablestatement.getUpdateCount() will return ZERO even though rows were updated.
5. I tested it with the stored proc doing SELECT - UPDATE - SELECT and again getUpdateCount() returns ZERO.
6. I tested it with the stored proc doing SELECT - UPDATE - SELECT - UPDATE and this time getUpdateCount() returns the number rows updated by the last UPDATE and not the first.
My Setup:
Mac OS X 10.3.9
Java 1.4.2
mysql database 5.0.19
mysql-connector 5.1.10 (connector/J)
Maybe I have exposed a bug in JDBC?
Thanks for your help.

Jschell thank you for your response.
I certainly don't mean to be rude but I often get taken that way. I like to state facts as I see them. I'd love to be proved wrong because then I would understand why my code doesn't work!
Doesn't matter to me if you are rude or not. Rudeness actually makes it more entertaining for me so that is a plus. Nothing I have seen suggests rudeness.
In response to your post:
When a MySql stored procedure has multiple sql statements such as SELECT and UPDATE these statements each produce what the Java API documentation refers to as 'results'. A Java class can cycle through these 'results' using callableStatement dot getMoreResults(), getResultSet() and getUpdateCount() to retrieve the resultset object produced by Select queries and updateCount produced by Inserts, Deletes and Updates.
As I read your question it seems to me that you have already proven that it does not in fact do that?
You don't have to read this but in case you think I'm mistaken, there is more detail in the following website under the heading 'Using the Method execute':
http://docsrv.sco.com/JDK_guide/jdbc/getstart/statement.doc.html#1000107
Sounds reasonable. But does not your example code prove that this is not what happens for the database and driver that you are using?
Myself I dont trust update counts at all since, in my experience some databases do not return them. And per other reports sometimes they don't return the correct value either.
So there are two possibilities - your code is wrong or the driver/database does not do it. For me I would also question whether in the future the driver/database would continue to behave the same if you did find some special way to write your SQL so it does do it. And of course you would also need to insure that every proc that needed this would be written in this special way. Hopefully not too many of those.
So this functionality is built into java but is not in common use amongst programmers. My java class did successfully execute a stored proc which Selected from and then finally Updated a table. My code displayed the contents of the Select query and told me how many rows were affected by the update.
It isn't "built into java". It isn't built into jdbc either. If it works at all then the driver and by proxy the database are responsible for it. I suspect that you would be hard pressed to find anything in the JDBC spec that requires what that particular link claims. I believe it is difficult to find anything that suggests that update counts in any form are required.
So you are left with hoping that a particular driver does do it.
I suppose it is rare that you would want to do things this way. Returning rowcounts in OUT parameters would be easier but I want my code to be modular enough to cover the situation where a statement may return more than one ResultSet object, more than one update count, or a combination of ResultSet objects and update counts. The sql may need to be generated dynamically, its statements may be unknown at compile time. For instance a user might have a form that allows them to build their own queries...
Any time I see statements like that it usually makes me a bit uncomfortable. If I am creating data layers I either use an existing framework or I generate the code. For the latter there is no generalization of the usage. Every single operation is laid out in its own code.
And I have in fact created generalized frameworks in the past before. I won't do it again. Benefits of the other idioms during maintenance are too obvious.

Query multiple values from tables with multiple conditions

I'm trying to display the addresses from an employee record. There are two tables: employees and emp_addresses. There can be any number of addresses which is defined by the address type.
What I want to do is get all the employees and all of the addresses for that employee in the same result.
Addresses table:
emp_id
address1
address2
address3
city
state
zip
type (either H for 'home' or W for 'work')
I would like the result set to be:
emp_id | home_address1 | home_city | work_address1 | work_city
Do I have to use a join? I'm not sure how to go about it.

See this page for different ways to do it:
http://www.oracle-base.com/articles/10g/StringAggregationTechniques.php
A related topic, that usually works better with a known number of columns, is Pivoting . See these links:
SQL and PL/SQL FAQ
There are ways to make pivoting work with a variable number of columns. See this thread:
Re: Report count and sum from many rows into many columns
What exactly are your requirements? Do you rally need separate columns for each address, or is it okay to have one big VARCHAR2 column that's formatted so it looks like separate columns? If you really need separate columns, do you know an upper limit to how many (e.g., there will never be more than 5)?

Showing the column names for the sample data isn;t nearly as helpful as shoiwing some actual data (with column names). Showing the header line that goes over the results isn't nearly as helpful as showing the actual results (with the header line).
Always say which version of Oracle you're using. Sting aggreagation and pivoting techiniques have changed significantly in every version since Oracle 7.
Do I have to use a join? I'm not sure how to go about it.Using a join, you could get one more address for every join, but since there could be any number of addresses, you'd need any number of joins, and that means dynamic SQL. Join probably isn't the best approach in this case.

Multiple results from AXL query in CUCM 6.1

Hi,
I have an application that uses an AXL query to retrieve IP/Extension information from a Call Manager. For versions 4.x and 5.x it works fine: I get results back for my query (note that I send up to 200 elements per query). On 6.x however, I only ever get one response, so although my query fires off 200 IP addresses (or extensions) I only get an answer back on the first one. I cannot see why this has changed. I have checked the DB schema.
The query is as follows:
<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/"

</tns:SelectItem>
</soap:Body>
</soap:Envelope>
As you can see it sends multiple (in this case 2) IP addresses. There is a second query that sends extension numbers. On earlier Call Managers this works fine, but on 6.x, it never returns more than one result.
Any assistance would be appreciated.

Congratulations on finding yet another bug. I'd really wish Cisco would start unit testing their APIs. While they use it themselves, the amount of functionality used (and thus tested) still pales in comparison on all the untested elements.
However, perhaps there's at least a workaround for you: why do you need to look up by ip address? The only scenario I can imagine right now would be looking up a device name based on a service request from a phone.. and you can just add something like
?device=#DEVICENAME# to the service url and the phone will tell you its device name when making the first request (you have to add the name as query string parameter or as a session variable for subsequent requests).

Q. How to get multiple results from a single column in a recordset using PHP

Hi everyone
Hope someone can help. I have a column called categories and about 5 categories listed. I want to show all products that are listed in say 2 categories. I only have basic php skills so only know how to pass a url value to show the products from 1 category e.g.
Select *
FROM product
WHERE category = colname
$colname = $_GET['category'];
URL...page.php?category=fruit
Questions is how do I get the products from multiple categories to show e.g. all products from categories 'fruit', 'dairy', 'meat'
Your help will be much appreciated as I am getting tired of beating my head against the wall. (should invent a PHP wall pillow and sell it online)
Thanks

$colname1 = $_GET['category1'];
$colname2 = $_GET['category2'];
$colname3 = $_GET['category3'];
Select *
FROM product
WHERE category IN ('$colname1', '$colname2', '$colname3')
>Your help will be much appreciated as I am getting tired of beating my head against the wall
My guess is that you are trying to build a web application without having first learned the basics on PHP and SQL. That's certainly the hard way.

Delete multiple rows from table/list control

Hi,
I want to have a table control in which a user can enter different entries, like this:
My program would read each entry at a time and do something.
However, I would like to give the user ability to delete multiple entries at once, like in an Excel spreadsheet - that is, the user selects multiple rows and presses "Delete" key and those entries get deleted. The Labview table does not allow this it seems - I can only delete one entry at a time - or I have to right-click and select Data Operations->Cut Data, which is awkward.
Is there a control better suited to what I want to do? I tried a Llist control, but it behaves in the same manner.
Thanks in advance!
Solved!
Go to Solution.

You could write your own routine. Use an Event Structure with a Key Down event. If the delete key was pressed and the table has focus delete the elements that are selected.
There are only two ways to tell somebody thanks: Kudos and Marked Solutions

How to remove multiple rows from table

Hi All,
in my application iam using two tables,
this is my code
int selection = wdContext.nodeA().getLeadSelection();
String num = wdContext.nodeA.geAAt(selection).getV_Num();
     for(int b=0;b<wdContext.nodeVn_Context().size();b++)
                                                  if(wdContext.nodeVn_Context().getVn_ContextElementAt(b).getVa_num().equalsIgnoreCase
                                                  (num))
                                                       wdContext.nodeVn_Context().removeElement(wdContext.nodeVn_Context().getVn_ContextElementAt(b));
here Vn_Context is having 4 rows, i mean size of Vn_Context is 4. when i use this code to remove that 4 rows based on the condition, which i gave in if, its able to remove only one row, so how to remove those four rows, is this code correct or not, please help me.

Hi sushma,
if you have 4 row then why should you give the condition for removing rrow..because when you gave condition the depends on your lead selection of getVa_num().so you will return perticullar row of getVa_num(). value of lad selection ..this would not match of other row value(getVa_num().so it will remove only that value of lead selection of getVa_num().
better you remove taht condition.
int selection = wdContext.nodeA().getLeadSelection();
String num = wdContext.nodeA.geAAt(selection).getV_Num();
for(int b=0;b<wdContext.nodeVn_Context().size();b++)
//if(wdContext.nodeVn_Context().getVn_ContextElementAt(b).getVa_num().equalsIgnoreCase
//(num))
wdContext.nodeVn_Context().removeElement(wdContext.nodeVn_Context().getVn_ContextElementAt(b));
no need to give the condition right now..
if you want to remove multiselection row,i mean selected row for multiple then you select the row as per your rows delete.
for(int b=0;b<wdContext.nodeVn_Context().size();b++)
if(lead==b || wdcontext.nodeVn_Context().isMultiselection(b){
wdContext.nodeVn_Context().removeElement(wdContext.nodeVn_Context().getVn_ContextElementAt(b));
this way you do solve your problem..
thanks

here i am facing problem as multiple entries from table /sapsll/prt is not being displayed only one.....but i have checked in table it is having two enteries
pls suggest
reagards
Nishant

Hi Nishant!
When you use 'for all entries' SAP (or database?) does a 'delete adjacent duplicates' on the result. This is necessary because of the special selection technique in this case.
You need to select enough columns from /sapsll/prt, so that your two entries will differ in the result.

Display a query with multiple results and a little addon :D

Hello everybody,
I wanna make a JSP page that displays multiple results from a query.
I wanna those results to appair in a table, a row each one, and also a little "square radio form buttton" that makes me select rows I wanna delete (with another button at the end)
any idea?
Better if you post the code, I'm not a good JSP writer
thanks everybody for your attention and your time
Kind regards

You're right.. I'd post nothing..
But it's all still in progress and I don't know what to post..
I understand is really difficult to invent some code without an origin (variables, functions, the bean), but also some general info would be really appreciated,also making a streched example if you can..
REQUESTS:
1) I need make a new JSP page, where will be visualize rows returned from a precise query selection
2)I use Beans, and my idea was to create Bean in JSP, open connection, make the query and create "some kind of FOR cycle" that fills a table, row by row
3)Every row must got a little "radio button" for a delete selection; the delete function will start when I press a specific button in this page(i'll use a servlet for this function)
4)The biggest and important trouble is HOW to display multiple rows in the Table

Constructing test with multiple results

Hi, I have the question for Lilybyri:
I learn to construct test with multiple results from your article:
Constructing Test with Multiple Results (CP5)
This is exactly what I need. My question is - can I use the radio button interaction or smart shape instead click box? What you recommend? I use CP7 or CP8.
Need to publishing the final test both HTML5 and SWF output. My test wil have 55 questions and 4 results score - one of them describe the personality of learner.
Yarik

Advasntage of click box and shape button is that they can have score
attached to it. That is not the case for radio buttons interaction that has
also limited formatting options.

As you see , am not using MVC
Thank you in advance

Post the "describe"s on MODEL_NEW and MODEL ...
Also ...
SELECT TO_NUMBER(FILE_NO),TO_NUMBER(SEAT_CAP),TO_NUMBER(WC) FROM BUSMODEL
ERROR at line 3:
ORA-01722: invalid numberThe errom message mentions BUSMODEL ... where is that coming from? Was that a real cut and paste?
