Is it possible to send a CachedRowSet object to a client?
I get an error when i try to do so. (I can't deploy the web service method that returns the CachedRowSet)
Is there a better way to return the result of database query to a client?
I'd appreciate any suggestions or sample code.

Hi!
The result of this query will be the max ID of users' IDs.
Let say we have:
String sql="select max(users.id) from users";
Statement st = ctx.conn.createStatement();
ResultSet rs = st.executeQuery(sql);
rs.next();
So you can get the max Id in the following way:
int maxId=rs.getInt("id");

I need return the result of a query on a stored procedure

I need return the result of a query on a stored procedure, I mean when I execute a stored procedure it returns a result set as a select query.
Best regards...

If you want some pl/sql code that can be used in a query as it were a table you may be interested in table functions:
SQL> create or replace type
2 t_emp is object (
3 name            varchar2(30),
4 hire_date date,
5 salary       number);
6 /
Tipo creato.
SQL> create or replace type
2 t_emptab is table of t_emp;
3 /
Tipo creato.
SQL> create or replace function tab_fun(p_dept in number)
2 return t_emptab is
3 e t_emptab;
4 begin
5    select t_emp(ename,hiredate,sal)
6      bulk collect into e
7      from emp
8     where deptno=p_dept;
9
10    return dip;
11 end;
12 /
Funzione creata.
SQL> select *
2 from table(tab_fun(20));
NAME                           HIRE_DATE SALARY
SMITH                          17-DIC-80        800
JONES                          02-APR-81       2975
SCOTT                          09-DIC-82       3000
ADAMS                          12-GEN-83       1100

Ability to send the results of a report query to a table in the database

Hi Guys
Is it possible to send the results of a report query to a table in the database ?
Thanks

Yes.
For this purpose, you can use :
* the delivers advanced option
http://gerardnico.com/wiki/dat/obiee/bi_scheduler/advanced_publication_delivers
* the SOA API

This two solutions need some development skills.

Pass the result of a SQL Query as table_name for another SQL Query

Hi All,
How to pass the result of a SQL Query as parameter to another SQL Query
Eg: I am doing the steps below.
1) select distinct table_name as TAB1 from all_tab_cols where table_name like 'T_%' and column_name like '%XYZ'
2) I want to pass the table_name from step 1 above as parameter to another query "select * from TAB1"
Thanks

ThanksYou should craete PL/SQL code with cursor which will accept a parameter and call that cursor inside the first one
But if the first sql returns only one row, you can do it with simple sql code
select * from (select distinct table_name as TAB1 from all_tab_cols where table_name like 'T_%' and column_name like '%XYZ')- - - - - - - - - - - - - - - - - - - - -

hi,
smart form to pdf--
All you have to do is call your SF to get OTF and then concert it to PDF. Works like charm:
DATA: p_output_options TYPE ssfcompop,
p_control_parameters TYPE ssfctrlop.
p_control_parameters-no_dialog = 'X'.
p_control_parameters-getotf = 'X'.
CALL FUNCTION v_func_name "call your smartform
EXPORTING
output_options = p_output_options
control_parameters = p_control_parameters
IMPORTING
job_output_info = s_job_output_info.
call function 'CONVERT_OTF_2_PDF'
tables
otf = s_job_output_info-otfdata
lines = t_pdf
and if u need more u can check below links also

Function-accept any datatype as an input param,return the result in cursor

I am trying to create a function which will accept any datatype as an input parameter and return the result in cursor.
Any thoughts?
I searched the web and came to know that there is a type called "ANYDATA" in Oracle 10g which will allow to accept any datatype variable.
But we are using oracle 8i.

I believe you are looking for an implementation of "generic functions" (Java) or "templates" (C++) in PL/SQL. I believe there is no such language feature.
Perhaps the best solution would be to convert the incoming data into a common type, and then call a common function from each of the overloaded functions.
realWork (int n) { [work]; return result; }
myFunction (varchar2 v) { n = to_number(v); return realWork(n); }
myFunction (char c) { n = to_number(c); return realWork(n); }
myFunction (date d) { n = to_char(to_number(d)); return realWork(n); }
etc. ?

One question of the method have two chance to return the result.

Hello All,
I get a problem at present.The code is following.
package com.ricky.test;
public class Test {
     public static void main(String args[]) {
          System.out.println(kkk());
     public static int kkk() {
          int k = 0;
          try {
               k += 2;
               return k;
          } catch (Exception e) {
               k++;
               return k;
          } finally {
               k += 5;
               System.out.println("get Here");
               return k;
}why does the result is 7.Isn't it return at the "try" part? and my eclipse alarm that "finally block doesn't complete normally";
thank you for your help!(I hope someone know my mean,because i'm not good at english. )

if I change the method to :
public static int kkk() {
          int k = 0;
          try {
               k += 2;
               return k;
          } catch (Exception e) {
               k++;
               return k;
          } finally {
               k += 5;
     }the result is 2(just execute k += 2 and then return the result.)
but if i change the method to
public static StringBuffer kkk1() {
          StringBuffer result = new StringBuffer("1");
          try {
               result = result.append("2");
               return result;
          } catch (Exception e) {
               result = result.append("3");
               return result;
          } finally {
               result = result.append("4");
               // return result;
     }the result is 124(the finally block effect the result value)Why?
Maybe is the result is the memory address.is that right?

Trying to display results from access database query on a JSP

Seem to be having real difficulty with this one, i keep getting a null pointer exception :(. Wondered if anyone could point me to any examples of displaying the results on jsp. The database is connected, as i can display the query on netbeans, but just not on a jsp.

I think it would be good if we had a section in these forums for pre-canned answers to the same questions that come up again and again. It would save time.
Here is a rough outline for using JSP:
* Read a JSP book.
* The JSP page (View in MVC) should get all the data it needs to display from a useBean and/or request.getAttribute().
* The JSP page should not have any business logic. Its purpose is to display data only (and have some submit buttons such as 'update').
You can do some basic client side validation using javascript if you want. Because there is no business logic in it, you can easily debug
your code in the servlet or business logic. You can't set breakpoints in JSP and examine data easily.
* When you click the submit button, all data from <input type="text" tags, etc is put into request scope via name/value pairs.
* Submit the JSP page <form tag to a servlet (Control in MVC).
* The servlet reads the name/value pairs of data from the JSP page via request.getParameter()
* The servlet should then instansiate a business object (Model in MVC), passing the data it got from the page to the business logic.
Example: ProcessPage processPage();
if(request.getParameter("updateButtonClicked"))
processPage.updateData(data from the jsp page)
* The business logic should instansiate a separate database object (DAO) to get data to/from the database. Business logic should not have sql in it.
Business logic should not generate html. Business logic should not have request objects in it.
* The business logic should return data to the servlet that in turn will put it in request scope via request.setAttribute() so the JSP page can draw itself.
* The servlet should then call up the approprate JSP page.

Use the results of an SQL query to create another query

I am working on a bidding/allocation system using C# and MySQL, and I am currently having difficulty implementing the “post-allocation” mechanics of the system. Let me explain how it works, before introducing the code:
When the bids are made on the system, they all have the position 0, so the first thing the system does is order them according to priority.
(bid table)
In this case, 5 bidders are interested in what is in plot 15, but we have not assigned them a position yet.
(bid table)
The system then organises the bids according to the order in which they are going to processed.
The bids are then allocated, but unfortunately there are only 3 spaces in plot 15 that can be allocated. As a result, we use the priority listing to determine which bidder gets what.
(booking table)
At this stage, I can say that I am stuck, there are two things that I want to do, both of which involve reusing the results of the query at step 2.
(bid table)
The bidders that have their job allocated should see: their bid.status updated
from Queued to Allocated,
the bid.position should
be set to 0,
and their job_id should
be set to the booking they have been allocated (i.e. booking.id).
The bidders that have not had their jobs allocated should see: their bid.status remain
as Queued, and their bid.position should
be set to 0 in
preparation for the method to run again
The difficulty I am having is in stage 3, how do I determine which jobs have been allocated and which ones have not, and then run the necessary SQL queries in order to make the updates?
My code so far is as follows:
// STEP 1a - SELECT BIDS
string query =
"SELECT t1.operator_id, t1.datetime, t1.plot_id, t1.position, t2.market_access FROM bid t1 " +
"JOIN operator t2 ON t1.operator_id = t2.id WHERE t1.status='Queued' AND t1.postcode=@postcode " +
"ORDER BY t2.market_access ASC, t1.datetime ASC";
var bidList = new List<BidList>();
var cmd = new MySqlCommand(query, _connection);
cmd.Parameters.AddWithValue(("@postcode"), _plot);
MySqlDataReader dataReader = cmd.ExecuteReader();
while (dataReader.Read())
var item = new BidList
OperatorId = dataReader["operator_id"] + "",
PlotId = dataReader["plot_id"] + "",
Position = dataReader["position"] + "",
Datetime = dataReader["datetime"] + "",
MarketAccess = dataReader["market_access"] + "",
bidList.Add(item);
dataReader.Close();
// STEP 1b - SET PRIORITIES
for (var i = 0; i < bidList.Count; i++)
var position = i + 1;
bidList[i].Position = position.ToString();
query = "UPDATE bid SET position=@position WHERE status='Queued' AND postcode=@postcode AND operator_id=@operator_id;";
cmd = new MySqlCommand(query, _connection);
cmd.Parameters.AddWithValue(("@position"), position);
cmd.Parameters.AddWithValue(("@postcode"), _plot);
cmd.Parameters.AddWithValue(("@operator_id"), bidList[i].OperatorId);
cmd.ExecuteNonQuery();
dataReader.Close();
// STEP 2 - ALLOCATE JOBS ACCORDING TO PRIORITY
foreach (var t in bidList)
query = "SELECT operator_id, plot_id, status FROM booking " +
"WHERE status='open' AND postcode=@postcode AND operator_id='0'" +
"ORDER BY datetime ASC;" +
"UPDATE booking SET operator_id=@operator_id, status='Allocated' " +
"WHERE (plot_id=@plot_id AND operator_id='0' AND status='Open') LIMIT 1;";
cmd = new MySqlCommand(query, _connection);
cmd.Parameters.AddWithValue(("@operator_id"), t.OperatorId);
cmd.Parameters.AddWithValue(("@postcode"), _plot);
cmd.Parameters.AddWithValue(("@plot_id"), t.PlotId);
cmd.ExecuteNonQuery();
dataReader.Close();
// STEP 3
CloseConnection();

I can't tell. When modifying row(s) you have to be able to uniquely be able to identify the row(s) in the database you want to modify. That is why I recommended the other day to use DataAdapter instead of the DataReader. You can with the
reader, but you need to unique identify the rows.
I can't tell from the limited amount of data you posted if in table 2 that there is only one row with the same operator id and plot id. It looks like in table 2 the 'id' number is unique. When working with a database with multiple tables you
need to be able to link tables together with primary keys (columns wit unique values). If the database isn't designed properly then it is impossible to do some operations. So you always have to make sure you design a database properly.

When you say table 2 are you referring to the bid or booking table?
Here is the table structure for the bid table
Here is the table structure for the booking table

How to use the result of a sql query for a max () function

Hi
I wrote a query on which i wrote
"select max(id) from users "
how can i use the returned value.
if i made the var name ="userid"
can it be userid.rows[0] or what.
thnx for any help

Hi!
The result of this query will be the max ID of users' IDs.
Let say we have:
String sql="select max(users.id) from users";
Statement st = ctx.conn.createStatement();
ResultSet rs = st.executeQuery(sql);
rs.next();
So you can get the max Id in the following way:
int maxId=rs.getInt("id");

Presenting/Selecting the "result rows" in a query

Hi,
Here is a description of my problem:
I have a query which returns values for materials grouped by purchasing groups:
Group 1 Material A KyeFigure
Group 1 Material B KyeFigure
Result: KyeFigure
Group 2 Material C KyeFigure
Group 2 Material D KyeFigure
Result: KyeFigure
I'm using a Web application designer chart to present the values graphically. I would like only to present the result rows in the chart, not item values. But since the chart picks all KFs presented in the table (items as well) this is not the case. I've tried to find a way in the chart-settings without any luck - it seems not possible. The documentation states that you're supposed to design your table the way you want it to show in the chart. However, I'm not allowed to redesign the cube or the report. It is not possible to drill up characteristics either (this affects the calculation).
My question is: Is there a way to extract the result rows into a new table and then base my chart on that one or simply somehow present only the result rows in a chart?
Best Regards
/Daniel

Hi Daniel,
You can create the query view in BEx Analyzer. After you execute the query, use filters, drill downs etc to get to the exact "view" of data that you would like you chart to present. Save this query view. Then in your web template assign this query view as the data provider.
Hope this helps...

How to show only the result line of a Query result ?

Hi Experts,
I want to show only the result line of the Query. Is this possible in query Designer ?
In BeX Workbook, I can hide the rows but they grow or shrink dynamically and hence it is unpredictable how many rows to suppress.
If you have any solutions/workarounds, please reply !
Rekha

VBA coding can be used to display just the Result rows.
Somthing like this - modify as needed.
This scans the range of query results looking to find the last row, then checks those rows to see if the word Result is found or not, deleting (or you could just hide) the detail rows. There is also a LEAF option in BEx Boolean options that returns a 1 or 0 depending on whether a row is a detail or result that could also be used to hide rows rather than looking for the presence of "Result" in a particular column
Sub SAPBEXonRefresh(queryID As String, resultArea As Range)
For rownum = 17 To 64000 Step 1
' col 2 is the Total Result, col 3 is the User Group result
If Cells(rownum, 2) = "" And Cells(rownum, 3) = "" Then
lastrow = rownum - 1
Exit For
End If
Next
For rownum = lastrow To 17 Step -1
If Cells(rownum, 2) = "Result" Or Cells(rownum, 3) = "Result" Then
Rows(rownum).Hidden = False
Else
' Rows(rownum).Hidden = True
Rows(rownum).EntireRow.Delete
End If
Next
End Sub

Question about cursors in a function and how to return the results

Hi all,
Some tech info:
I'm using Oracle 11G database and APEX 4.0.2.00.06
I use three cursors in a function. My function is called in an APEX standard report, like this by example:
SELECT fnc_exp(tab.arg1, tab,arg2) FROM table_exp tab;
My question is: how can I return the values calculated from my function to a standard APEX report? Before, this function was used like this by Oracle Forms to fetch the cursors in the right table columns:
open c_a;
fetch c_a into :loc.arg1;
close c_a;
open c_b;
fetch c_b into :loc.arg2, :loc.arg3, :loc.arg4, :loc.arg5;
close c_b;
Thanks for your advices!
Maybe my solution is not right, if you have better ideas, please suggest :)
PS: If you need more details, please ask which you need.

Hi,
I don't think you can do exactly like that in APEX.
Go for a pipelined function if you want the value be returned from the function.

Displaying results from a database query using servlets

I have this HTML form where users can search a MS Access database by entering a combination of EmployeeID, First name or last name. This form invokes a Java Servlet which searches the database and displays the results as an HTML page. I am giving the user the choice of displaying 3, 5 or 10 results per page. I want to know how to do that using servlets. If a particular search results in 20 results, the results should be displayed in sets of 3, 5 or 10 depending on the user's choice. If the user makes a choice of 5 results per page then 4 pages should be displayed with a "next" and "previous" button on each page. I want to know how this can be done.

Arun,
I'm not sure how to do this using JSP as I have not worked on JSP.
But I can give you a hint on how to do this within normal java class as I've used this in my current project.
In your core class/bean that generates the entire resultset, you need to run a loop that will scan through the desired number of records in the resultset.
To do this, you have to have skip and max parameter in your URL.
Somthing like http://server.com/myservlet?skip=0&max=10 to display first 10 records, http://server.com/myservlet?skip=10&max=10 to display next 10 records. The <next>parameter would be fed in by the user by a simple form in your web-page. If you need to hold this <max-num-of-recs-per-page> param, you can store it in a cookie (since this is nothing crucial piece of info, don't need to use session obj etc...cookie will do) and get the value each time you display the resultset.
So, essentially, suppose you are at the first page and you wish to show 10 recs at a time. The link for "Next" button would be http://server.com/myservlet?skip=10&max=10
when at the second page, you'll have
"priv" button as http://server.com/myservlet?skip=0&max=10 and
"next" button as http://server.com/myservlet?skip=20&max=10 and so on...
hope this makes sense..
