SQL Query Set

Hi,
I am building a LOV in Designer based on one table usage and
I am adding an SQL Query Set based on another table to create an UNION on those two tables.
When I generate, I get :
CDG-03485 ERROR: SQL Query Set TEST.LOV.UNION: Inconsistent item datatypes or wrong number of items in query set
Where can I find help on how to use SQL Query Set ? Or how can I solve this problem ?
Thank you,
Denise

The problem has been solved...

How to set a sql query time out with jdbc:oracle:thin

should i change the JDBC driver with jdbc:oralce:XA:thin or other driver with XA?

SQL query timeout may be set with setQueryTimeout.
http://java.sun.com/j2se/1.4.2/docs/api/java/sql/Statement.html#setQueryTimeout(int)
A query timeout bug is fixed in Oracle JDBC Drivers release
10.1.0.2.0 (10g)
FIXED BUG-2249191
In the Server Internal Driver, setting the query timeout does not
+(and likely will never) work. The query execution will not be+
canceled when the timeout expires, even if the query runs forever.
Further, after the query returns, the execution of your code
may pause for the length of the timeout.

SQL Query (updateable report) Region - Conditionally Hide and Set Values

SQL Query (updateable report) Region - Conditionally Hide and Set Values
Outline of requirement :-
Master / Detail page with Detail updated on same page using SQL Query (updateable report).
The detail region has the following source
SELECT item_id,
       contract_id,
       CASE WHEN hardware_id IS NOT NULL THEN
               'HA'
            WHEN backup_dev_id IS NOT NULL THEN
               'BD'
            WHEN hardware_os_id IS NOT NULL THEN
               'HS'
       END item_type,
       hardware_id,
       backup_dev_id,
       hardware_os_id
FROM   "#OWNER#".support_items
WHERE contract_id = :P26_CONTRACT_IDThe table support_items implements arced relationships and has the following columns
CREATE TABLE SUPPORT_ITEMS
ITEM_ID         NUMBER                        NOT NULL,
CONTRACT_ID     NUMBER                        NOT NULL,
HARDWARE_ID     NUMBER,
BACKUP_DEV_ID   NUMBER,
HARDWARE_OS_ID NUMBER
)A check type constaint on support_items ensures that only one of the fk's is present.
      (    hardware_id    IS NOT NULL
       AND backup_dev_id IS NULL
       AND hardware_os_id IS NULL
OR    (    hardware_id    IS NULL
       AND backup_dev_id IS NOT NULL
       AND hardware_os_id IS NULL
OR    (    hardware_id    IS NULL
       AND backup_dev_id IS NULL
       AND hardware_os_id IS NOT NULL
      )    Hardware_Id is a FK to Hardware_Assets
Backup_dev_id is a FK to Backup_Devices
Hardware_os_id is a FK to Hardware_op_systems
The Tabular Form Element based on item_type column of SQL query is Displayed As Select List (based on LOV) referencing a named list of values which have the following properties
Display Value     Return Value
Hardware Asset    HA
Backup Device     BD
Computer System   HSThe Tabular Form Elements for the report attributes for hardware_id, backup_dev_id and hardware_os_id are all Displayed As Select List (Based on LOV).
What I want to do is only display the Select List for the FK depending on the value of the Select List on Item Type, e.g.
Item_Type is 'HA' then display Select List for hardware_id, do not display and set to NULL the Select Lists for backup_dev_id and hardware_os_id.
Item_Type is 'BB' then display Select List for backup_dev_id, do not display and set to NULL the Select Lists for hardware_id and hardware_os_id.
Item_Type is 'HS' then display Select List for hardware_os_id, do not display and set to NULL the Select Lists backup_dev_id and hardware_id.
There are properties on elements to conditionally display it but how do we reference the values of the SQL query Updateable region? they are not given a page item name?
Also on the Tabular For Elements there is an Edit tick against a report item - however when you go to the Column Attributes there is not a property with which you can control the Edit setting.
What's the best way of implementing this requirement in APEX 3.1?
Thanks.

Welcome to the forum: please read the FAQ and forum sticky threads (if you haven't done so already), and update your profile with a real handle instead of "user13515136".
When you have a problem you'll get a faster, more effective response by including as much relevant information as possible upfront. This should include:
<li>Full APEX version
<li>Full DB/version/edition/host OS
<li>Web server architecture (EPG, OHS or APEX listener/host OS)
<li>Browser(s) and version(s) used
<li>Theme
<li>Template(s)
<li>Region/item type(s) (making particular distinction as to whether a "report" is a standard report, an interactive report, or in fact an "updateable report" (i.e. a tabular form)
With APEX we're also fortunate to have a great resource in apex.oracle.com where we can reproduce and share problems. Reproducing things there is the best way to troubleshoot most issues, especially those relating to layout and visual formatting. If you expect a detailed answer then it's appropriate for you to take on a significant part of the effort by getting as far as possible with an example of the problem on apex.oracle.com before asking for assistance with specific issues, which we can then see at first hand.
I have a multi-row region that displays values and allows entries in a number of fields.Provide exact details of how this has been implemented. (An example on apex.oracle.com is always a good way to do this.)
I should like the fields to be conditional in that they do not permit entry, but still display, if certain conditions apply (e.g. older rows greyed out). Can this be done? Almost anything can be done, often in multiple ways. Which are appropriate may be dependent on a particular implementation, the skills available to implement it, and the effort you're willing to expend on it. Hence it's necessary to provide full details of what you've done so far...

Setting a Default Value in SQL Query Report

Hello:
We are using a SQL Query Report to provide a mass update to a table. We are using the apex.collection and having it display a number of records in a SQL Query Report for mass update. We have 14 columns in the report, for which the first 11 are populated via the collection. The remaining 3 are open for input but the individual making the updates. We've were able to provide a default value for 2 of the remaining 3 columns using a named LOV's - however the fourth column we would like to default a sysdate - but we are not successful.
We've attempted many things but none seem to work, including adding that column to the collection and assigning it a default sysdate value. We've also tried changing the settings in the report attributes --> Tabular Form Elements by setting the Display as to: Datepicker, Default type to PL/SQL Expression and setting the default to sysdate. We've also tried caputuring a date on the previous page and loading it onto the report page and trying to default the date column to a page item default.
I'd appreciate any help.
Thanks
FYI - we are using version 3.2

use as default
to_char(sysdate, 'dd/mm/yyy') where the format is your application or item date format

SQL query with parameter returns empty result set, please help !!!

Hi there,
When I use the following query :
<sql:query var="beroepsthemas" >
select *
from beroepsthemas
where beroepsthemaid = ?
<sql:param value="12"/>
</sql:query>
When I want to browse the result set with :
<c:forEach items="${beroepsthemas.rows}" var="rij">
it shows no records. But it must return at least one.

When the same code is run on the live environment, it works just fine.
The difference is :

What can there be wrong !!

I didn't catch this. I think you may need to update the database driver.

How to set fetchsize of sql Query when using Database Adapter.

Hi All,
I am using DatabaseAdapter to connect to database and retriving huge amount of data.For improvement in the performance I want to set the "fetchsize" of sql query. I know fetchsize can be preset in Java using Jdbc 2.0 API.Please let me know how to set this value in BPEL when using DBAdapter?
Thanks
Chandra

I talked to the developer of the db adapter - and he told me this feature will be available in BPEL PM 10.1.3 (which is supposed to be production later this year, and a public beta soon). If this is an emergency I would recommend going throug Oracle support and have them file an enhancement for 10.1.2.0.2

Is there a way to consolidate calculations used in SQL Query Data Sets?

I am building SQL Query Data Sets against multiple DB Views which all have different date formats. I have the date parameter working well, but want to consolidate the changes that I have to do to it especially for the quarter. For example the SQL against a monthly view would use "where year_month > to_char(:ST_DATE, 'YYYY-MM')" which is not too hard, but to make that work for the quarterly view I need several concats and a decode to get a "> '2012-Q2'". I would like not to have to do this within every where clause. I had put this into a global element hoping to use that in a filter for the data set, but the filter does not have access to global elements only parameters.
Is there any way to refer to a calculated global element from the data set to do this? I am using Layout Templates, so even if I wanted to I could not do the condition within the template.
     Thanks,
     Rick

Change the following line to include the red coloured parts
<div class="MasterColumn" spry:repeat="ds4" spry:setrow="ds4" spry:hover="MasterColumnHover" spry:select="MasterColumnSelected">
<span>{Dsp_#}</span><span>{Dsp_WkDay}</span><span>{Dsp_Event}</span>
</div>
The add the following style rule to your document:
.MasterColumn span {
    display: inline-block;
I hope this helps.

Setting current values in Multiple Select List in SQL Query based Report

Hi,
I have a report based on a sql query that contains a multiple select list. Unfortunately I cannot get the multiple select list to display the current values (p_value) correctly. I have created a page item, :p311_current_versions, that is set using a pre-header process and it returns a value with a colon delimited format e.g. '10.1.2.1.0:10.1.2.2.0'. Then this item is used in the sql query to set the current value (p_value) of the apex_item.select_list_from_query function. However when the table is displayed, instead of having two entries, 10.1.2.1.0 and 10.1.2.2.0 selected, it has an extra entry '10.1.2.1.0:10.1.2.2.0' selected.
Here is my code:
select distinct a.product, a.version from (
select distinct
apex_item.display_and_save(2,product)||apex_item.hidden(1,env_product_id) PRODUCT,
APEX_ITEM.SELECT_LIST_FROM_QUERY(3,decode(product, 'HTTP Server' , :p311_current_versions, version), 'SELECT distinct version d, version r FROM ebs_tech_stack where
product ='''||PRODUCT||'''',
decode(PRODUCT, 'HTTP Server' ,'multiple="multiple" style="width:170px"','style="width:170px"'),
'NO') as version
from ebs_environment_tech_stack
where environment_id = :p311_umgebung_id) a order by a.product
If anyone can help me figure out how to set the current values correctly I'd be really grateful!!
Thanks in advance,
Jean

Jean,
I don't think this is possible using the apex_item package. The select_list_from_query function accepts only a single value for the second parameter.

Xml parsing error while selecting whole result set for sql query

Thanks and regards,

What does the XML look like? It appears that some of the supposed XML stored as a CLOB is not really valid XML. Find the row in the table that is causing your issue and review the "XML" in it.

Set the column length in an sql query

Hi,
Is there a way to set the column length in a query without using sqlplus commands like row size and format column.
I'd like to do it just from the sql query itself.

Bilal, thanks for the nice problem! Another possibility for duplicate checking is to write a small PL/SQL function returning 1 if a duplicate id is found, then equate it to 0: 'Duplicate_Token_Found (p_str_main VARCHAR2, p_str_trial VARCHAR2) RETURN NUMBER'. This would parse the second string and might use p_str_main LIKE '%,' || l_id || ',%' for each id. Anyway the full query (without that) is given below:

JSP Servlet and convert the result set of an SQL Query To XML file

Hi all
I have a problem to export my SQL query is resulty into an XML file I had fixed my servlet and JSP so that i can display all the records into my database and that the goal .Now I want to get the result set into JSP so that i can create an XML file from that result set from the jsp code.
thisis my servlet which will call the jsp page and the jsp just behind it.
//this is the servlet
import java.io.*;
import java.lang.reflect.Array;
import java.sql.*;
import java.util.ArrayList;
import java.util.logging.Level;
import java.util.logging.Logger;
import javax.servlet.*;

request.setAttribute("id",Lesidentifiant);
Lesnoms.add(rs.getString("postname"));
request.setAttribute("nom",Lesnoms);
rs.close();
stmt.close();
*catch* (SQLException e) {

Liste des campagnes here i will create the xml file the problem is to display all rows
<hr>
<table>

<tr>
<td>Comment</td>

<%
for( int i=0;i<comments.size();i++){
out.print("<li>" + (String) comments.get(i) + "</li>\n");

This is how i used to create an XML file in a JSP page only without JSP/SERVLET concept:
<%@ page import="java.sql.*" %>
<%@ page import="java.io.*" %>
<%
// Identify a carriage return character for each output line
int iLf = 10;
char cLf = (*char*)iLf;
// Create a new empty binary file, which will content XML output
File outputFile = *new* File("C:\\Users\\user\\workspace1\\demo\\WebContent\\YourFileName.xml");
//outputFile.createNewFile();
FileWriter outfile = *new* FileWriter(outputFile);
// the header for XML file
outfile.write("<?xml version='1.0' encoding='ISO-8859-1'?>"+cLf);
try {
// Define connection string and make a connection to database
Connection conn = DriverManager.getConnection("jdbc:derby://localhost:1527/SAMPLE","app","app");
Statement stat = conn.createStatement();
// Create a recordset
ResultSet rset = stat.executeQuery("Select * From posts");
// Expecting at least one record
*if*( !rset.next() ) {
*throw* *new* IllegalArgumentException("No data found for the posts table");
outfile.write("<Table>"+cLf);
// Parse our recordset
// Parse our recordset
*while*(rset.next()) {
outfile.write("<posts>"+cLf);
outfile.write("<postname>" + rset.getString("postname") +"</postname>"+cLf);
outfile.write("<comments>" + rset.getString("comments") +"</comments>"+cLf);
outfile.write("</posts>"+cLf);
outfile.write("</Table>"+cLf);
// Everything must be closed
rset.close();
stat.close();
conn.close();
outfile.close();
catch( Exception er ) {
%>

Please state your problem that you are having more clearly so we can help.
I looked at your code I here are a few things you might consider:
It looks like you are putting freely typed-in comments from end-users into an xml document.
The problem with this is that the user may enter characters in his text that have special meaning
to xml and will have to be escaped correctly. Some of these characters are less than character, greater than character and ampersand character.
You may also have a similiar problem displaying them on your JSP page since there may be special characters that JSP has.
You will have to read up on how to deal with these special characters (I dont remember what the rules are). I seem to recall
if you use CDATA in your xml, you dont have to deal with those characters (I may be wrong).
When you finish writing your code, test it by entering all keyboard characters to make sure they are processed, stored in the database,
and re-displayed correctly.
Also, it looks like you are putting business logic in your JSP page (creating an xml file).
The JSP page is for displaying data ONLY and submitting back to a servlet. Put all your business logic in the servlet. Putting business logic in JSP is considered bad coding and will cause you many hours of headache trying to debug it. Also note: java scriptlets in a JSP page are only run when the JSP page is compiled into a servlet by java. It does not run after its compiled and therefore you cant call java functions after the JSP page is displayed to the client.

Set Text Item To SQL Query Result

I am trying to set a text item to a SQL query result. Something like the following:
(I am trying to accomplish this in the SOURCE portion, set to 'SQL Query' source type, of the text item properties)
SELECT empno FROM emp WHERE empno = :SEARCH_EMPNO;
This only displays as the literal text when the application renders and not the value from the SQL query.
I apologize if this has already been posted but I could not find what I am looking for. I have seen posts that reference a pre-region computation but do not know the exact steps to accomplish the results I want.
Thanks in advance for anyone's time to help me with my issue.
Kyle

Scott,
The literal that displayed (I have fixed it) was the actual SQL statement: SELECT empno FROM emp WHERE empno = :SEARCH_EMPNO;
I have resolved the issue, using SQL Query as the "Source Type" and Always, replacing any existing value in session state as the "Source Used" for the properties of the item.
What I was trying to accomplish is a search text item that would return the data for that record in a table into other text items, for each column in that record, for update; based on the search text item as a unique SQL query search for that record.
Thank you for your quick reply!

Setting the cell width in a Tabular Form (SQL Query (updateable report) )

version 3.2.1
I have a Tabular Form (SQL Query (updateable report) ) and I have a column that is a VARCHAR2(4000) that when displayed extends the cell to the full length (which of course makes sense).
How can I set the width of this cell to something like 30 or 50 and wrap the contents?
Thanks,
Joe

Scott,
Thank you for replying.
Your suggestion kinda worked. I say kinda because when the report is first displayed the cell is the full width and appears to ignore the width setting. There is a Select List on the report to restrict some of the data that is displayed. When a selection is made from this Select List, it appears that the cell width is then adjusted to what was set, but not for every selection from this Select List.
I made the width entry in Tabular Form Element - Element Width
Any idea why the width setting is ignored?
Thanks,
Joe
