PL/SQL Procedures using TIME

hello all,
i need some help with using time in my table. how do i insert a time (what data type do i use, and what does the INSERT statement look like), eg. i want a time like 1:00:00am, 2:00:00pm in my receiveTime column.
i have a table:
ID receiveTime
1 need a time
2 need a time
3 need a time
THEN, how would i write a condition for this procedure, the condition is that i want to compare my System Time with the Time in the receiveTime column.
eg. if system time > receive time THEN blah blah;

Link to PL/SQL procedure using a Template Manager template.

Hi,
I need to link a portal application report (report from SQL query) to a SQL procedure that uses a template manager template. The PL/SQL procedure requires parameters. I'm not be able to create a link based on a PL/SQL procedure. The only solution I found is to setup a link to a Form based on that procedure. But the form is only used to call the PL/SQL procedure by clicking the submit button and redirect to the template.
Another question:
Is it planed to support dynamic links based on column conditions?
I'm using Portal release 3.0.7.6.2.
thanks in advance
Jens

Jens,
You may want to search the Oracle9iAS Portal Applications forum. It may have the answer you are looking for. This forum is for questions related to the Portal Development Kit.

Generating Web Service from PL/SLQL procedures using ODSI

1) Is there a way for us to generate REST based web services from PL/SQL procedures using Oracle data services Integrator? If Yes, Can you please point me to any available documentation
2) I am trying to create a phyiscal data source based on PL/SQL procedures in the hope of turning these data sources into web services. I created a JDBC connection in web logic server console and am trying to view the packages under APPS but ODSI always crashes after selecting APPS. Is there a way to resolve this?

Hi..
We came accross this problem a while back (I think it was us that the patch was created for). The patch was released under CR369707.
Additionally it took us a while to figure out how to use it correctly.. Here's the info for it from a mail i receievd from our support contact..
Here is more information from engineering on the patch:
This is patch for filtering Stored Procedures in the New Physical Data Service Wizard. It is a partial fix to the problem. It just does filtering - it still retrieves all the jdbc metadata for everything that matches the filter. Ideally, the wizard would let you explore the stored procedures - retrieving the name only - and once you selected a stored procedure, it would retrieve the argument types (which is the expensive part).
Copy these two files to a safe place
<bea_home>\<aldsp_home>\eclipse-plugins\dsp\eclipse\plugins\com.bea.dsp.ide.external_10.3.0\dsp-ide-ldshredder.jar
<bea_home>\<aldsp_home>\eclipse-plugins\dsp\eclipse\plugins\com.bea.dsp.ide.import_metadata_10.3.0.jar
Replace the files with the ones provided in the patch (which I sent you be eMail recently).
Creating Relational Database Physical Data Services -> Stored Procedures will be affected as follows :
The Search field used to represent a pattern for the stored procedures only, and this patterns were applied against every schema visible to ALDSP. The patch allows you to also specify a list of catalogue patterns (useful only when applicable), a list of schema patterns and a list of procedure name patterns. These lists are separated by the pipe symbol, and the lists themselves are command-separated. The catalogue and schema patterns are regular expressions, the procedure pattern is for a database 'like' clause. For, Oracle, the catalogue patterns are not applicable.
Example:
|ODM1,ODM2|B% // look in schemas containing the strings ODM1 or ODM2 for procedures that start with B
// possible results would be MY_ODM1.BUILDER, ODM2.BOTTOM
|^ODM$|B%D // look in the ODM schema for procedures that start with B and end with D.
Also - if there is a search string in the Search box, that search string will be applied to the schema when you click on the + to expand it in the Tree.
Note that once a schema has been 'explored' - either by a search, or by expanding it in the tree, further searches will not update it's children. You would need to quit the wizard and restart.
Once you get the patch if you have issues let me know..

Calling pl/sql procedure from a java class.

I have an onSubmit event that needs to call a pl/sql procedure using the named connection. Can anyone tell me how this is code in a Model 1 ADF JSP page?

Look at the following related thread:
Programatically setting attribute values.

PL/SQL procedure -- log files?

Say when i execute a PL/SQL procedure using SQL* Plus. Is there a place where these executions are stored/logged? Any trace files?
And, when a Java program calls my stored procedure, is there a place these transactions are stored, just to check what exactly is being passed to my stored procedure and what the procedure gave back as result set?
Any pointers will be appreciated. Thanks.

Hi
Use a system.out.println(parametername) to check what values you are passing to the procedure.. you can see the results in your application server console.

Calling PL\SQL procedures

What's the best way to invoke a PL\SQL procedure using Java?
I am hoping to use the values passed from the JSP into the database for computations but don't know how to call the procedure after the commit.
Any ideas?

call.registerOutParameter(1,OracleTypes.CURSOR);
call.setString(2,partNumber_tf.getText().toString());
call.execute();
OracleResultSet rset=(OracleResultSet)call.getObject(1);
/* use caching result set cuz it is non scrollable stored proc result */
model = new CachingResultSetTableModel(rset);
result_tbl = new JTable(model);
status_tf.setText(result_tbl.getRowCount()+" matching Rows found.");
jScrollPane1.getViewport().add(result_tbl, null);
rset.close();

Performance of AQ when using callback procedure (using PL/SQL notification)

I am enqueueing XMLType in AQ.XML file is large in size.NOw I want to dequeue the AQ using PL/SQL notification(using callback procedure which will call DBMS_AQ.DEQUEUE to dequeue the AQ and process the XML.After fetching the data from XML ,I want to store these data in another table columns).
Please suggest,In this case which approach would be better to dequeue the AQ table :
1.PL/SQL notification(using callback procedure)
OR
2.Scheduling the call to DBMS_AQ.DEQUEUE to dequeue the AQ table
What would be the impact on performance of above two approaches?

Hi,
The question of performance is not down to the technique one employes to enqueue/dequeue, but at a basic level, is relative to the number of messages!
The is what the Oracle documentation states:
>
When persistent messages are enqueued, they are stored in database tables. The performance characteristics of queue operations on persistent messages are similar to underlying database operations. The code path of an enqueue operation is comparable to SELECT and INSERT into a multicolumn queue table with three index-organized tables. The code path of a dequeue operation is comparable to SELECT, DELETE, and UPDATE operations on similar tables.
>
So, if anything, the dequeue is a fraction more time & resource consuming. However, it is only a "fraction". You could always add multiple subscribers to dequeue if you want!
You could ofcourse choose to have non-persistent messages if your application does not need the kind of fault-tolerance that persistent messaging offers, which speed things up, but only a bit, so don't get too excited about it!
There are other things to consider however, which you may wish to read up on before getting bogged down on whether you should use notification or the scheduler:
- Is your system clustered?
- Concurrency on a single queue (i.e. multiple enqueues/dequeues, but single queue)
- Propogation latency issues
Read about these and much more at:
http://download.oracle.com/docs/cd/B19306_01/server.102/b14257/perform.htm
Finally, whether you pl/sql notification or not and whether you use dbms_scheduler is down to your application requirements!

Creating page items from pl/sql procedure and using them on a page

I have a page containing 2 select lists (P21_DEPARTMENTS and P21_DATE). Originally I added them as items that were "select list with submits". The problem is that based on the clearance level of the currently logged on user I only wanted the P21_DEPARTMENTS to be a select list if the user was an administrator. If however the user is not an admin then I want the page to have a hidden form field called P21_DEPARTMENTS that stores the user's department and has a label item that has the department name.
There is also a report region that generates a table based on the department selected from the select list (if the user is an admin) or the value stored in the hidden form field if the user is not.
My problem is that I cannot have both those items on the same page and use the HTML built-in authentication to determine which item should be rendered because I need to use the same ID for both items so that the stored procedure in my report region doesn't break. HTML does not permit items to share the same ID.
I tried to circumvent the problem by creating a stored procedure that performs all of the item rendering in the procedure and uses "htp.p()" to output all of my HTML code. This solution would allow me to pass a parameter into the procedure informing me as to whether or not the user is an administrator. If the user is an administrator the procedure would use a conditional statement and render a select list. If not, the hidden form field and label option would be used instead.
I finally got the stored procedure working perfectly. Now I am encountering the most bizarre thing. Since the "select list with submit" was not working (I used the same code that gets generated when I created other items using htmlDB's GUI) I decided to use a JavaScript function instead that gets triggered by the onChange event. I send along the value that is currently selected in the select list and in the function I set:
location.href='http://www.myoraclesite.com/pls/htmldb/f?p=111:21:729740000000000000::NO::P21_DEPARTMENTS:1';
In theory this should work. The problem is that it doesn't. The page reloads and the P21_DEPARTMENTS select list is not pre-selected.
The only thing I can think of is that when htmlDB generates page items that you've created with it's own admin tool it assigns some internal guid or something as opposed to when someone tries to generate dynamic page items of their own from a pl/sql procedure it's like the application doesn't even know they exist.
Any help would be GREATLY appreciated.
My only other solution would be to create a totally separate page (one for admin and another for non-admin). I would really like to avoid this.
Thanks in advance.

I would love to be able to generate my menus and
various other items in my htmlDB applications in much
the same way I can using ASP, PHP and Cold Fusion.
Users should have the ability to write server-side
code wherever they feel like it. The way htmlDB works
right now I spend more time trying to figure out how
to create simple effects and generate simple
interfaces when I need to be building a portal. Ami - it's important to understand that HTML DB is not like other languages. Thus, trying to force concepts which are common in other languages into HTML DB will often result in more work.
It's definitely worth the time to go over the HTML DB 2-day Developer, which can be found here: http://www.oracle.com/technology/products/database/htmldb/pdf/B14377_01.pdf
I can build a portal using Classic ASP, C#, PHP or Cold
Fusion in like 1/10 of the time that it takes me to
build one using htmlDB. I understand that this is not
meant for the hard-core programmer but no web
programming application in today's day and age should
prevent experts from getting under the hood.And I can build a Portal in HTML DB in 1/10 the time it will take me to do it in any other language. It's like anything else - proficiency comes with practice and work.
As for getting under the hood, there is plenty of places you can do that with HTML DB. Keep in mind that HTML DB itself is an HTML DB application, so the limits on what you can build with HTML DB are virtually limitless.
Sorry for the vent there. After spending the last 2
days trying to figure out how to implement such a
straightforward thing and now being informed that it
can't be done kind of bugged me.I understand your frustration, as I've been there before. My rule for beginners is that if you are writing more than a line or two of code in the first week, you're doing something wrong. Stop, take a break, and then use the ample resources (including searching this forum) to help solve your problem. There are plenty of resources available for you to learn about HTML DB on the HTML DB home page: http://otn.oracle.com/htmldb
Good luck,

Deploy warnings using a PL/SQL procedure (from a Public Transform Package)

OWB Version: 10.2
I am receiving the following warnings when I attempt to deploy a map that contains a reference to a custom pl/sql procedure that is setup in a public transformation package:
Warning
ORA-06550: line 115, column 32:
PLS-00112: end-of-line in quoted identifier
ORA-06550: line 115, column 9:
PLS-00103: Encountered the symbol "." when expecting one of the following:
:= . ( @ % ; not null range default character
I reviewed the OWB generated code and I discovered the OWB is a adding two double quotes in front of any reference to the package name. For example.....
BEGIN
COMMIT;
sql_stmt := 'ALTER SESSION DISABLE PARALLEL DML';
EXECUTE IMMEDIATE sql_stmt;
IF NOT ""ZZTEST"."INIT_SF_USER_CLAS_St" THEN
* note the "" in front of ZZTEST, which is the package name.
Has anyone else encountered this issue? I can manually correct the generated the code, but it would be overridden every the time the map is deployed. I encounter the same issue if I import a custom pl/sql procedure from the database into OWB using the Metadata Import Wizard and use the imported procedure in a map. However, I can setup an standalone procedure or function as a public transformation and the map deploys successfully. Please advise.
Regards,
Matt

You have to create a job to start your procedure.
Example :
* http://psoug.org/reference/OLD/dbms_job.html
Then create a procedure to start your job, call it from your dashboard and you're done.

where sumsg_msg_data.msg_data%TYPE, sumsg_msg_data.msg_data1%TYPE and sumsg_msg_data.msg_data2%TYPE are all defined as RAW(2000). When I test the PL/SQL code seperately, everything is ok, but if I use the Pro*C code to read, the ORA-01458 always happen, unless I change the SIZE_DATA_SEG value to 4000, then it passes, and the result read out also seems ok, either the bigger or smaller value will encounter ORA-01458.
I think the problem should happen between the mapping from internal datatype to external VARRAW type, but cannot understand why 4000 bytes buffer will be ok, is it related to some NLS_LANG settings, anyone can help me to resolve this problme, thanks a lot!

It seems that I found the way to avoid this error. Now each time before I read RAW(2000) data from database, i initialize the VARRAW.len first, set its value to SIZE_DATA_SEG, i.e., the outside buffer size, then the error disappear.
Oracle seems to need this information to handle its data mapping, but why output variable also needs this initialization, cannot precompiler get this from the definition of VARRAW structure?
Anyone have some suggestion?

Improve the performance in stored procedure using sql server 2008 - esp where clause in very big table - Urgent

Hi,
I am looking for inputs in tuning stored procedure using sql server 2008. l am new to performance tuning in sql,plsql and oracle. currently facing issue in stored procedure - need to increase the performance by code optmization/filtering the records using where clause in larger table., the requirement is Stored procedure generate Audit Report which is accessed by approx. 10 Admin Users typically 2-3 times a day by each Admin users.
It has got CTE ( common table expression ) which is referred 2 time within SP. This CTE is very big and fetches records from several tables without where clause. This causes several records to be fetched from DB and then needed processing. This stored procedure is running in pre prod server which has 6gb of memory and built on virtual server and the same proc ran good in prod server which has 64gb of ram with physical server (40sec). and the execution time in pre prod is 1min 9seconds which needs to be reduced upto 10secs or so will be the solution. and also the exec time differs from time to time. sometimes it is 50sec and sometimes 1min 9seconds..
Pl provide what is the best option/practise to use where clause to filter the records and tool to be used to tune the procedure like execution plan, sql profiler?? I am using toad for sqlserver 5.7. Here I see execution plan tab available while running the SP. but when i run it throws an error. Pl help and provide inputs.
Thanks,
Viji

You've asked a SQL Server question in an Oracle forum. I'm expecting that this will get locked momentarily when a moderator drops by.
Microsoft has its own forums for SQL Server, you'll have more luck over there. When you do go there, however, you'll almost certainly get more help if you can pare down the problem (or at least better explain what your code is doing). Very few people want to read hundreds of lines of code, guess what's it's supposed to do, guess what is slow, and then guess at how to improve things. Posting query plans, the results of profiling, cutting out any code that is unnecessary to the performance problem, etc. will get you much better answers.

Execute Dynamic SQL statement using procedure builder

i want to execute a dynamic SQL statment using procedure builder not using forms
because my statement depending on a variable table name
i know that i can do that from forms using
FORMS_DDL('SQL_STAT');
but i wanna to use the procedure builder
which function i should use and how?
please explain in example if you don't mind.
thanks

Hi,
You can very well use DBMS_SQL Package supplied by Oracle for doing this.
Search for DBMS_SQL in OTN. You will get all info regarding this.
Regards.
