PL/SQL code written in db or in application...????

Hi ,
Which is the best...at performance , maintability... e.t.c.???
To write PL/SQL as validation process of data values going to be inserted in db:
1) as db trigger (before insert or update row-level trigger)
2) in application level - in Forms10g...
This PL/SQL code compares some pairs of data values only.... there DML statement....
Both db server and App server are considered to be or in the same machine or in two machines very close to each other...
Note: i use Db10g .
Thanks...

It is all about moving parts. How many there are. Where they are located.
The less moving parts, the less the complexity, the bugs - and the better the performance (less wheels to turn to crunch data), the easier the maintenance and the better the flexibility.
Part of this is having the moving parts close to the data. Kind of obvious - what is faster? Shipping data from the db engine to a front-end application via a app server and web server? Or shipping the data from the db (SQL) engine to a PL/SQL process running as part and parcel of db instance? IPC is significantly faster than TCP/IP.
Having the moving parts close to the data also means that it can scale with the data. Oracle is good at scalability. It is designed at its very core to be scalable. Partitions to reduce I/O. Shared Server to reduce o/s resource footprint per client session. Shared pool to re-use SQL. DB buffer to cache data. RAC to run multiple db instances for a single physical database. Etc. Etc.
With the application moving parts being close to the data, it inherits this scalability. You can "multi-thread" application code using table pipelines. You have access to forking application code using background processes (DBMS_JOB and DBMS_SCHEDULER). You have bulk processing in order to transfer more data per SQL engine call, between the buffer cache and your application, and thus also reduce expensive context switching.
This list goes on and on.
All this is summarised into the following rules.
Rule 1. Do it in SQL.
Rule 2. Only when SQL cannot do it, use PL/SQL. (e.g. SQL is not suited for managing and controlling process flow - PL/SQL is)
Rule 3. Only when PL/SQL cannot do it, use <insert-language-here> (e.g. PL/SQL cannot render a Windows grid on the client - but Delphi/C#//Java can).
Also keep in mind that in the modern client-server paradigm we deal with a web architecture. Which means the client is a web browser. And this means that PL/SQL can pass the data (HTML) required by the client (web browser) to render the User Interface.
Have a look at APEX (Oracle's Application Express) for how this works. http://apex.oracle.com
All you need to develop web applications is APEX (a PL/SQL product suite in the database) and a web browser. Kickass stuff... :-)

Performance tuning in PL/SQL code

Hi,
I am working on already existing PL/SQL code which is written by someone else on validation and conversion of data from a temporary table to base table. It usually has 3.5 million rows. and the procedure takes arount 2.5 - 3 hrs to complete.
Can I enhance the PL/SQL code for better performance ? or, is this OK to take so long to process these many rows?
Thanks!
Yogini

Can I enhance the PL/SQL code for better performance ? Probably you can enhance it.
or, is this OK to take so long to process these many rows? It should take a few minutes, not several hours.
But please provide some more details like your database version etc.
I suggest to TRACE the session that executes the PL/SQL code, with WAIT events, so you'll see where and on what time is spent, you'll identify your 'problem statements very quickly' (after you or your DBA have TKPROF'ed the trace file).
SQL> alter session set events '10046 trace name context forever, level 12';
SQL> execute your PL/SQL code here
SQL> exitWill give you a .trc file in your udump directory on the server.

Funny bug in pl sql code

Hi,
I have written a code to upload data from csv file to oracle table. it gives me a funny error. I have given below the sample contents of .csv file
"4951","TCSPL (TRADING A/C)","470","TISCO",20050419,"P",362.6550,212,0.00
"4951","TCSPL (TRADING A/C)","470","TISCO",20050419,"S",361.7500,212,-191.86
"4951","TCSPL (TRADING A/C)","477","ASHOKLEY",20050928,"P",28.5000,200,0.00
"4951","TCSPL (TRADING A/C)","477","ASHOKLEY",20050928,"S",28.4960,200,-0.80
for the first time if i run the sql code it uploads first 2 records and does not upload third record, if i change the figure of =-191.86 to 191.86 (if i remove - mark ) then it uploads all the records, if i reverse it back it does not the third record, the structure of the table is like this ( the data column where this data get inserted is number(15,4) datatype)
this type of problem is happening with that perticular row only, though several such kind of combination is there in the csv file.

Hi
Try to debug you procedure inserting a better exception handling and some dbms_output.put_line.
E.g.
ElsIf i =9 then
Crec.profit := var;
dbms_output.put_line(var || ' - ' Crec.profit);
End If; Try to put the exception handling in the loop ... while i < 10 loop ... .
I don't think that it's an Oracle bug. It's a human error in your code!

Can a PL/SQL code of timesten be called in oracle or vice versa

Hi
In IMDB cache setup with AWT cache group , the pl/sql code or procedure that is written in oracleDB can it be called in TimesTen and vice versa
example: In a stored procedure the DML's that are performed will be updating the cache tables and log table in oracleDB.
Will there be any performance impact.
Regards
Siva Kumar

A PL/SQL procedure can exist in Oracle DB, in TimesTen, or in both. You control that by where you create the procedure. Procedures that exist in Oracle can really only be called in Oracle and can only access data in Oracle. Procedures that exist in TimesTen can only be called in TimesTen and can only access data in TimesTen. There is a limited capability, using the TimesTen PassThrough capability to call PL/SQL procedures located in Oracle, from Timesten, and for Timesten PL/SQL procedures to access data in Oracle. Using PassThrough does have some overhead.

Output of PL/SQL code in Client Machine.

I am writing the output of PL-SQL code to a file. Later on I will use that output in a UNIX shell script.
For that I am creating directory object and using the UTL_FILE.fopen and UTL_FILE.put_line functions of UTL_FILE package in Oracle.
E.G.
1) CREATE OR REPLACE DIRECTORY MYDIR AS '…………………ANY VALID DIRECTORY PATH IN SERVER……………………………’;
2)
DECLARE
config_file UTL_FILE.file_type;
lv_i BINARY_INTEGER := 1;
BEGIN
lv_i := 2;
config_file := UTL_FILE.fopen ('MYDIR', 'test.txt', 'W');
UTL_FILE.put_line (config_file, 'This is test file' || 'lv_i= ' || lv_i);
UTL_FILE.fclose (config_file);
END;
But UTL_FILE.fopen and UTL_FILE.put_line functions in oracle can write only to ORACLE SERVER side files.
However, I want to write the output of the file to the UNIX box from where I am accessing database (using sqlplus DB_USER_NAME/DB_PASSWORD@DB_NAME).
Is it possible in Oracle 10g (10.2.0.4.0) to write the output of PL/SQL code in client machine?

Hi,
Just an idea. I haven't tried it before in unix server since there's no chance to.
In Windows you can actually map the specified folder where you want to write the file, so in this case, you just need to find a way on how you can map/mount the folder/directory where you want your file written. UTL_FILE can be used to write files(if the file does not exists) and write text in that file on a directory accross the network as I have done it before in Windows machine.

Including an Expression in SQL Code with Columns from a Table

The code under MY CODE will not work. Getting error saying 00922-from keyword not found where expected..
In the examples I looked up, the months_between function was written as a select statement like:
Select
months_between (sysdate,me607.mbr_dob) / 12 as date
from mbr_exp me607
Can anyone help me with the syntax I need to include this with my SQL code as below?
Thanks..
MY CODE:
Select

This seems to be your problem, the pipe is wrongly defined. On Windows it looks like

REPORT WITH PL/SQL CODE

DECLARE
SQ VARCHAR2(100);
BEGIN
SQ := 'SELECT * FROM EMP WHERE EMPNO=7788';
RETURN SQ;
END
THE ABOVE PL/SQL CODE WORKING FINE
BUT I NEED CONDITION BASED ON ENAME
SQ:='SELECT * FROM EMP WHERE ENAME=''SCOTT'';
IT IS GIVEING ERROR
WHAT TO DO?

Hi,
You're missing the final quote - you have the quotes for SCOTT but not the one to close the SQ string:
DECLARE
SQ VARCHAR2(100);
BEGIN
SQ := 'SELECT * FROM EMP WHERE EMPNO=''SCOTT''';
RETURN SQ;
ENDAndy

How to 100% Protect PL/SQL Code By Wrapped in Oracle Database 10g R2

Hello,
Is Possible to 100% Protect PL/SQL Code By Wrapped in Oracle 10g R2 ?
If it is not possible by wrap in oracle 10g R2,
Please, let me suggest, how i will be able to 100% protect PL/SQL code in Oracle Database 10g R2.
Because, I have lot of functions, procedures & package's in my project.
Which is running in field filed.
So, i have needed to protect 100%.
Also, will i convert to al functions, procedures & package's to .pll file ?
And .pll file to .plx file?
Is it possible to convert .plx file to .pll file ?
Please, let know any better solutions in this case....
Regards
Mehedi

Hello,
No, wrapping is not a 100% secure method. It could prevent your code from amateurs, but not from professional hackers. Look at the article http://docs.oracle.com/cd/B28359_01/appdev.111/b28370/wrap.htm#BEHGBJAA
It says: "•Wrapping is not a secure method for hiding passwords or table names.
Wrapping a PL/SQL unit prevents most users from examining the source code, but might not stop all of them."

Unable to depoly Web Serivce for the source code written in other editors

Hi all,
I am planning to implement webservice with the following code. But I am facing few problems with this can some body help me with this.
The code looks like this AND IS NOT WRITTEN IN Jdeveloper BUT EDITPLUS
package package1;
public class Sum
public int getSum(int a, int b)
          return a+b;
package package2;
public class Sub
public int getSub(int a, int b)
          return a-b;
package package3;
import package1.*;
import package2.*;
public class Mul implements TestInterface
     Sum sm = new Sum();
     Sub sb = new Sub();
public int getMul(int a, int b)
          return sm.getSum(a,b)*sb.getSub(a,b);
public static void main(String [] args)
          Mul ml = new Mul();
          System.out.println(âThe result of (3+6)*(3-6) is â+ ml.getMul(3,6));
package package3;
interface TestInterface extends java.rmi.Remote;
     public int getMul(int a, int b) throws java.rmi.RemoteException;
I have written this in editplus. Not in Jdeveloper.
Now I want publish getMul() as web service using Jdeveloper.
I have created a new application work space. And from File-->New
I have choose project from existing source and imported âpackage3â.
At this stage it was unable to find the class files Sum and Sub so I placed Sum.class and Sub.class in Appliction1-Project1-classes-
Now the Mul class did not have any errors and it compiled fine. When run it gave the correct output.
Using the web service wizard I was able to generate wsdl file , deployment descriptors etc.
The problem I was facing was form this stage when I am trying to deploy it on to a standalone oc4j server it is not able generate the WebServices.war file and hence is not deployed on to the server.
With the same code written in Jdeveloper everything is working fine.
My doubts are
1)     why is it not able to generate WebService.war file?
2)     It is giving some ClassNotFound exception during the deployment. But when compiled and run its giving the correct output.
3)     Even when everything was written from within the Jdevelper it did not include Sum.calss and Sub.class in WebSevice.war. Is there any way we could mention during its (WebService.war) generation , the class files to be Included.
The other issue is how to add an existing source code to already existing project. In my case Once I have imported package3 I also want to import package2 and package1 in different steps.
I thank in advance for helping me.

Can you tell us what you mean by correct type of project?
You can start with an empty project. Then, you have to create an "EAR file" deployment profile (New Gallery / General / Deployment Profiles).
So when I deploy a J2SE module onto oc4j server should I specify the class path? If so where ? How can I solve this problem?
Once you deploy your code into oc4j, it becomes a J2EE application. You don't need to deal with the classpath - just make sure that all the required code is included in your .war file. To do so, check the list of classes packaged under the deployement properties dialog.
Can you send me the links of few articles where I can learn more about these kind of stuff?
If you want to assemble applications without to use JDeveloper wizard, you have another option: using the WebServiceAssembler tool that is par of the oc4j bits will help you to do this from a command line promt, and will handle the J2EE packaging aspect for you.
See online documentation (10.1.2): http://download-west.oracle.com/docs/cd/B14099_04/web.htm
In the "Developer's Guide", chapter 9 is about "Web Services Tools"
For JDeveloper J2EE samples, you can start by looking at the OBE: http://www.oracle.com/technology/obe/obe_as_1012/j2ee/index.html
Hope this helps,

How to reference LEVEL in a TREE's SQL code

Is it possible to somehow reference LEVEL in a tree's sql code so that you can use a decode statement to selectively create links on specific levels only i.e. NOT on the root level?
e.g.
select "CHILD_ID" id,
"PARENT_ID" pid,
"NAME" name,
decode( LEVEL, 1, null,'f?p=' || :APP_ID || ':43:' || :APP_SESSION || '::::P43_CHILD_ID:' || CHILD_ID) link,
null a1,
null a2
from TREETABLE
order by name
one solution I've implemented is to create a DB function e.g.
create or replace function get_tree_level(v_child_id number) return number
is
v_level number(2);
begin
select level
into v_level
from TREETABLE
where child_id=v_child_id
start with child_id=1
connect by prior child_id= parent_id;
return v_level;
end;
and then use
decode( get_tree_level(child_id) 1, null,'f?p=' || :APP_ID || ':43:' || :APP_SESSION || '::::P43_CHILD_ID:' || CHILD_ID) link,
but this is too slow as I have quite a few records in the tree and takes too long to render
regards
Paul P

OK I found a workaround after reading
How to add URL to tree
The view my tree is build on is constructed out of 3 unions and 4 "selects" ( the first select creates the ROOT NODE where "1" is also used as a hard coded foreign key (Parent_id), in the company table.)
I just added a new column called tree_level to the query which is hard coded wrt its level on the hierarchy.
e.g.
CREATE OR REPLACE FORCE VIEW COMCONSTUTREE ("CHILD_ID", "PARENT_ID", "NAME","TREE_LEVEL") AS
select 1 as child_id,to_number(null) as parent_id ,'Company' as name,*1 as tree_level* from dual
UNION
select COM_ID, 1, COM_NAME,2
from company
UNION
select CON_ID,CON_COMPANY_ID, substr(con_name,instr(con_name,' ')+1) ||', '||substr(con_name,1,instr(con_name,' ')-1),3
from contact
UNION
select STU_ID,STU_CONTACT_ID, STU_LAST_NAME||', '||STU_FIRST_NAME ,4
from student;
the tree code now becomes
select "CHILD_ID" id,
"PARENT_ID" pid,
"NAME" name,
decode( tree_level,1, null,'f?p=' || :APP_ID || ':43:' || :APP_SESSION || ':TREE:::P43_CHILD_ID:' ||CHILD_ID) link,
null a1,
null a2
from COMCONSTUTREE"
order by name

PL/SQL Code not working without debug statements

Hi Guys,
I have a pl/sql code in a procedure, logic iterates through almost 40K records, conditional delete and update.
When I execute this code, I dont see the deletes and updates happening, though procedure executes for 8 minutes and exits wihtout any error, execption.
In same procedure when I write some debug statements like dbms_output, then everything seems to be working fine.
I know this scenario happens in Oracle Forms, wehre we use SYNCHRONIZE.
But this is plain pl/sql procedure.
any thoughts on this?
Av.

COMMIT ?
Aside from that, no idea what your procedure looks like, what it does, what version of Oracle you are using, how you are determining "I dont see the deletes and updates happening". etc...
You'd need to provide a slew of information for anyone to give you any meaningful help.
I can only assure you that DBMS_OUTPUT doesn't do magic :)

Can I have a PL/SQL code for LOV

Hi,
I apologize for this dumb question. I have been so out of touch with dev (almost 8 years). Plus new to pl/sql.
I am creating a status report application. On the dashboard, I currently have some metrics (horizontal charts). I wanted to expose these metrics based on filter.
I had created 2 filters. The first one will identify the type (Week, Month, Qtr or Year) and the 2nd filter would be based on the type. For e.g. if I select Month as type, the 2nd filter should show May-12, April-12 etc. Once I select the 2nd filter, I should use them to show the appropriate metrics. The metric that I currently have would show all the projects that users have worked on during the week/month/qtr or year (depending on the 1st and 2nd filter).
On the dashboard region, I added a condition to check if the value for both 1st and 2nd filter is not null. This allows me to show the dashboard only if the 2 filters have been selected.
For the 2nd filter, I need to write a PL/SQL code to show the LOV.
I am assuming that the pl/sql would return a SQL query. The SQL query will be based on week, month etc. Is that right?
Thanks
balaji

where
and     :p1_filter_1 = 'WEEK'
union all
select
        /* Month query */
from

union all

PL/SQL code written in db or in application...????
