AJAX and PL/SQL
Hi guys,.I have a PL/SQL procedure that calls a php script (which returns an XML document) using AJAX. I want to change it to call another procedure PL/SQL instead of the PHP script. I created a PL/SQL procedure that mimics the output of the PHP script exactly, but AJAX no longer works. Here is my code:
PL/SQL - calling procedure
PROCEDURE myWebpage is
begin
-- Web page header
htp.print('
function getSubcategories(){
var ajaxRequest;
try{
// Opera 8.0+, Firefox, Safari
ajaxRequest = new XMLHttpRequest();
} catch (e){
// Internet Explorer Browsers
try{
ajaxRequest = new ActiveXObject("Msxml2.XMLHTTP");
} catch (e) {
try{
ajaxRequest = new ActiveXObject("Microsoft.XMLHTTP");
} catch (e){
// Something went wrong
alert("Your browser broke!");
return false;
}
}
}
ajaxRequest.onreadystatechange = function(){
if(ajaxRequest.readyState == 4 && ajaxRequest.status == 200){
var xmlDocument = ajaxRequest.responseXML;
var options = xmlDocument.getElementsByTagName("option");
var subcatSelect = document.getElementById("subcat_sel");
subcatSelect.options.length = 0;
for(var i=0; i<options.length; i++)
subcatSelect.options[i] = new Option(options.firstChild.data);
if ( document.requestInfo.pCategory.value == "Academic" ) {
document.getElementById(''acad_div'').style.display = "inline";
}
else {
document.getElementById(''acad_div'').style.display = "none";
document.requestInfo.pContactMethod.value = "Email";
}
}
}
// THIS LINE IS THE PHP CALL
ajaxRequest.open("POST", "http://mysite.com/dsu/query/ajaxquery.php", true);
// THIS LINE WILL BE USED FOR PL/SQL CALL
// ajaxRequest.open("POST", "http://mysite.com/SSBDADTST7/pkgAjax.ajaxQuery", true);
ajaxRequest.setRequestHeader(''Content-Type'', ''application/x-www-form-urlencoded'');
ajaxRequest.send("p_category=" + document.requestInfo.pCategory.value);
}
');
-- REST OF WEBPAGE
end myWebpage;
PHP SCRIPT
<? PHP
Query Script Ajaxquery.php
include("..) /.. /.. ("/ ajax/connect.php");
$category = $_POST ['p_category'];
Query
If ($category == 'University') {}
$query = ociparse ($conn, ' select subject_desc from all_subjects)
order of subject_desc');
}
else {}
$query = ociparse ($conn, ' select subcategory_desc in the categories)
where category =------". $category. '\'
and active = \'A\'
order of subcategory_desc');
}
ociexecute ($Query);
Output
Header ("Content-type: text/xml");
echo "<? XML version=\"1.0\"? " > ';
echo "< options >";
While (ocifetchinto ($query, $row, OCI_ASSOC)) {}
$keys = (array_keys ($row));
{foreach ($keys as $k)
echo '< option > '. $row [$k]. "< / option >";
}
}
echo "< / options >;
? >PL/SQL - Called Procedure
PROCEDURE ajaxQuery (p_category in varchar2) is
type ref_cursor is ref cursor;
subcat_curs ref_cursor;
lSubcat categories.subcategory_desc%type;
Start
If (p_category = 'Academic') then
Open the subcat_curs for
Select subject_desc from all_subjects
order of subject_desc;
on the other
Open the subcat_curs for
Select subcategory_desc in the categories
where category = p_category
and active = 'A '.
order of subcategory_desc;
end if;
HTP. Print (' <? xml version = "1.0"? > ');
HTP. Print ('< options >');
loop
extraction of subcat_curs in lSubcat;
When the output subcat_curs % notfound;
HTP. Print ('< option >' | lSubcat |) ("< / option > ');
end loop;
HTP. Print ('< /options >');
close subcat_curs;
end getSubcategories;Now I have tested the output of the PHP script and the second PL/SQL procedure and they are identical. I uncommented the line in the first PL/SQL procedure under "THIS LINE WILL BE USED FOR PL/SQL CALL". But the line where
var xmlDocument = ajaxRequest.reponseXML;
is returning a null object when I use the PL/SQL call. Do I need to modify something else for this to work?
Here's my oracle version, just in case:
Oracle Version:
Oracle Database 10g Enterprise Edition Release 10.2.0.4.0 - 64bi
PL/SQL Release 10.2.0.4.0 - Production
CORE 10.2.0.4.0 Production
TNS for IBM/AIX RISC System/6000: Version 10.2.0.4.0 - Productio
NLSRTL Version 10.2.0.4.0 - Production
Thanks

Note that PL/SQL is used to create a dynamic Mime stream - in your case, a stream of text/html . It is then read by mod_plsql (web server module) and passed (via web server) to the client.
The Ajax code is executed by the client web browser.
If this Ajax code behaves as expected, then the stream of text/html you generated is not correct and does not match the content of the task force generated using PHP.
So it is not a PL/SQL or Oracle specifically. He's a programmer pure question - not an Office of the coding language.
I don't like your approach by the way. There are inherent problems, mixing the source code of 2 different languages in the same unit of code, where the compiler/Analyzer offers no integration between the two. This forces you to deal with the only language, JavaScript in your case, as text strings.
Automatically, this is a question regarding the use of quotation marks, special characters, formatting and so on. He changed this code complex and difficult. Debugging more often impossible.
The right approach is one of the following conditions.
If the Ajax code is static, create a dedicated JavaScript file that contains the code. Inside PL/SQL, question one JavaScript include statement to load this JavaScript in the browser.
If the Ajax code is dynamic (should not be - you need to generate JSON from PL/SQL instead), and then store the model code Ajax as a CLOB in a table. Use special chips to mark the dynamic parts (for example where a token like + #NAME #+ indicates the text to be replaced). At runtime in PL/SQL, use the replace() function to create a CLOB from the model, with the text of replacement if necessary. Then write this CLOB variable content in the browser via the package htp .
The fundamental issue here is of modularization. Modularize your designs. Modularize your code. It's the cornerstone of software engineering. The difference between a hack and quality in all aspects - scalability and performance for maintenance for debugging.

Catproc.SQL and Catalog.sql run by mistake in the production database while the database is running.
Hello
DB version: 10.2.0.4.0 cluster db. EA
Version of the OS: Win server 2008
by mistake one of our dba ran CATPROC.sql and CATALOG.sql scripts in our live production rac database.
After that issues rose and developers face invalid objects. We erased our users manually main invalid objects and it looks like everything is working well for the moment.
BUT when I checked object invalid status, he showed me some 600 disabled objects. I'm afraid in the future will come from unacceptable errors.
What should do? any suggestions? are we in danger? What are workarounds.
Thank you
You must connect a SR with Oracle's Support.

vCO and MS SQL Express not connect
Hi, I installed vCO and MS SQL Express locally. But I can not not to connect to SQL from the server configuration CO v.
On the database tab, I use these settings:

Host VM ORCHESTRATOR is a member of the field of MS, but I installed vCO as the local administrator.
Can you help me please?
Milan
You can get this working... to change your user name 'administrator' and instead of letting the empty field, enter "VM ORCHESTRATOR" (I guess it's the name of your workstation) - when you use is not a field, this field must be the name of your workstation as well, whenever I install on vCO on a Windows Server , I never checked the use of NTLM authentication box... so if my first note does not help, also clear this check box.

Hello world
During playback of Oracle ADF Real World Developer's Guide, I noticed the dates match occurring in JDeveloper is different from what is the list in the book. JDeveloper is failing to oracle.jbo.domain.Date, but according to the book:
DATE java.sql.Date DATE type is mapped to java.sql.Date if the column in the table is a no time didn't need information zone. DATE java.sql.Timestamp DATE type is mapped to java.sql.Timestamp if the column in the table has a component "time" and that the client needs to zone information. TIMESTAMP java.sql.Timestamp The TIMESTAMP type is mapped to java.sql.Timestamp if nanosecond precision is used in the database.
In general, is it better to use java.sql.Date and java.sql.Timestamp instead of oracle.jbo.domain.Date? Using java.sql.Date and java.sql.Timestamp could save me some headaches conversion date. And, is there a place in JDeveloper to display these maps? I looked around and didn't see anything.
Thank you.
James
User, what version of jdev we are talking about?
In GR 11, 1 material versions db types date and timestamp are mapped to types of domain data that represents a wrapper for the native data types. The reason was that the framework can work with the domain types regardless of the underlying data type.
Since Oracle 11 GR 2 maps the types DB to java types (default selection, you can change it when you create a model project, you can set the Data Type Mapping). Once the pilot has business components define you cannot change this setting it would break existing components such as eo or vo.
So if you are working wit 11 GR 1 subject, you must use the domain types, if you work with GR 11, 2 or 12 c, you can use the domain types, but it is recommended to use the java type mapping.

The elements and the SQL Types
I just started learning apex and I'm confused about the application and page elements. Since they can serve as a kind of variables in the SQL and PL/SQL (for example, by using the syntax variables bind), at some point they should be prescribed a type, since SQL and PL/SQL are two strongly typed languages.
It seems that the items have types, see the documentation (http://docs.oracle.com/cd/E11882_01/appdev.112/e11947/bldapp.htm#BCEDCGGH), but I don't know how they correspond to the SQL types.
For example, I saw that to_date is always used with items of type date picker, implying that it is a string of SQL type.
So the question. What have SQL type apex page/application parts, is what type conversion do I need to use when dealing with items in SQL and PL/SQL? They are all VARCHAR2 (4000) as far as I know - anything application are the same and the page elements is adjustable in number or date more. Put date or number will include only internal validation, check whether the format is match the parameters of globalization of applications.

Files catproc. SQL and catalog.sql
I am using oracle 10g recently that I managed two files catproc.sql and catalog files by connecting to sys
After running these files in sys when I select
Select * from tab;
no lines have been returned
(1) these files will show any eeect on database
(2) to Toad when I connect to the Toad for data base is to show all the user sys tables
will there be an effect of the execution of these files After running these scripts, you will need to create spfile from pfile and the startup pfile from this file file
is incorrect. Catproc.sql and Catalog.SQL don't change the values of instance parameter. The instance parameter files are useless to be recreated.

Java - functions and PL/SQL procedures?
It is my understanding that Java can call stored PL/SQL and PL/SQL procedures and functions can call Java stored procedures and functions.
The reason why I ask this is that my company is considering options on how to migrate our product. Our consultant said that PL/SQL cannot access Java procedures. I think they can. I am not well educated in the present, but I'm trying to learn as much as I can before we committed.
Our graphical interface is written in Java, but they are still debating the back-end (lots of great transaction). Some think that it should be written in Java, some Java State itself would be too slow. I read the mantra of AskTom - SQL, PL/SQL, Java, and C.
So, what's the scoop?
What is the preference, or best practices? >
It's the answer that confused me: PL/SQL cannot access Java procedures in an external JAVA virtual machine, but Oracle has its own JAVA virtual machine integrated in the database (except express edition).
>
Since I wrote it I'll try to explain it.
Oracle, with the exception of the express edition, has a functionality integrated into the database (including the JVM) Java. You can import the java classes and jar files in the Oracle database and run Java code using the JAVA virtual machine, which is part of the Oracle.
By "External JVM", I hear one application that is launched from the OS and Java Virtual Machine and it is a stand-alone process; in other words, not a part of the Oracle or Oracle of FMV at all.
Both JVMs running in the 'sandbox' different and do not have access to each other code, classes, or process. Of course, they may be able to communicate using sockets, JNDI, EJBs and other features of wrapper, but they cannot access each other classes, instances of class or methods as they would if only there wasn't one JAVA virtual machine.
So a stand-alone Java application can call stored procedures in Oracle (even those written in Java), Oracle PL/SQL procedures can call Java from Oracle procedures, Oracle Java procedures can call Oracle PL/SQL procedures. But procedures Oracle PL/SQL or Java can't call procedures or access to Classes or class instances that are part of an external JAVA virtual machine.

think that the books and example scripts/SQL. Thanking, Rajiv.
Well, let's first - become familiar with SQL * Plus - Oracle standard tool. Maybe it's a little 1980
but it will be available on absolutely every system you use. As long as a student, I don't think you
have a lot of money to spend on tools - so download Oracle's SQL developer tool (free)
and experiment with it.
On your own systems, there are already scripts - do (presumably in Unix - if Windows, use the search)
Tool) - $ORACLE_HOME do you find. -name "*.sql" and watch the rdbms/admin scripts. In addition,
There are a few free libraries available.
http://www.Oracle-base.com/DBA/scripts.php
www.rampant.cc/Internals.zip
http://www.Oracle-Developer.NET/utilities.php (look at the MOAT).
Then, after that, you could look at the site of Tanel Poder and Christian Antognini (both peak) also
Google "Oracle SQL/PL/SQL script libraries.
There are enough out there on the internet to keep you going for years :)
For PL/SQL, the best authors are Connor McDonald and Steve Feuerstein, if you want to invest in
a book.
HTH,
Paul...

I got the value as 3969.
I tried with the same string. I know that the maximum length of the SQL string is 4000 and PL/SQL is 32767. but the thing is when am a length of the string in PL/SQL as less than 4000, then iwhy must not be run alongside SQL?
Can you help me out on this issue?

Outside chr (256), are there other characters of white space available?
White space characters are listed on http://en.wikipedia.org/wiki/Whitespace_character.
From the point of view of the old MS-MS-BACK/ASCII characters, a white space character was #256 as the chariot of normal space was #32. He was also a space compared to a difficult space.
You need to look at the character set you use - ASCII is a set of characters in a single byte, and not the same thing.
You can use the SQL DUMP() function to watch the characters in a string. For example
select dump( my_string_column ) from my_table where ...

Creation of database without executing the script catproc.sql and catalog.sql
Hello
I created the database of towing without running catalog.sql and catproc.sql. Someone knows what's the downside to not run them?
ARM You can run them at any time, and Yes, you must be connected as sysdba. In fact, it's in the scripts generated dbca.

The Essential Guide to Dreamweaver CS3 with CSS, Ajax, and PHP by David Powers
The Essential Guide to Dreamweaver CS3 with CSS, Ajax, and PHP by David powers:
This book would help me learn more about Spry and Ajax and how applications may be lodged with them, if I have my e-commerce site works on a compiled C code cart (ShopSite) but supports scripts PHP server-side or is - this only for shopping carts based on PHP itself (like X-Cart)?
I'm not sure. Someone please let me know if I can buy this book. Thank you. ahsenabro wrote:

You don't need no prior knowledge of PHP or Ajax, but you must
know the basics of HTML and CSS. As I say in the introduction, "You."
don't need to be an expert, but do not have a curious mind.
It teaches the basics of web site design, or he's trying to list
each unique feature in Dreamweaver CS3. There are many other books
to fill this gap. However, by working through this book, you will gain a
in-depth knowledge of the most important features of Dreamweaver.

The book provides detailed coverage of the features of Spry 1.4
Dreamweaver CS3, which can be applied to any site. With minor
adjustment, you can also use Spry 1.6. It is important to realize,
However, the features of Spry/Ajax in Dreamweaver CS3 * cover of no
asynchronous requests to the server. The ability to communicate
asynchronously with the server has been added in Spry 1.6. If it has
the asynchronous server calls and answers you are looking for, your
programmer will need to dig into the documentation for Spry 1.6 on the
Adobe Labs site and manually code it.
The Spry features covered in the book are Spry, Spry UI widgets effects
(menu accordion, tabbed and folding panels), Spry
Widgets of validation and Spry XML data sets.

Yes. All Spry techniques can be used on any web page. This is not
you have to be a PHP one.

CF8 Enterprise and MS SQL Server
I need to transfer a CF8 Enterprise application off the coast of a MS Access database to a MS SQL Server existing database/environment (I guess I'm technically Piggy-Back my database in an 'existing' instance).
I created my database of SQL Server, responsible for access to the elders of the base and is now looking to connect to CF administrator.
I get the "java.sql.SQLException: [Macromedia] [SQLServer JDBC Driver] [SQLServer] Login failed for user (null)". Reason: not associated with a trusted SQL Server connection. "error. I've filled in the id and password, which causes this error. I checked, and the properties of the server (using SQL Server Enterprise Manager) and the validiated defined for authentication (SQL Server and Windows) mixed mode, but don't can't get further.
Any ideas? I was able to verify that SQL Server has been using authentication in mixed mode (both Windows and SQL Server), and that TCP/IP is enabled and using port 1433.
I had to create an ID local within SQL Server and then used this combination ID / password in the configuration of the data source in the CF administrator And then Bingo, that worked.
Thanks for all you suggestions and patience. Oh, and I also bought a book from SQL Server 2000 to help me get through the code changes required between MS Access and MS SQL Server.
