Pl/sql procedure to validate/review

Hi folks, looking for some good practice/guidelines for evaluating and reviewing a big pl/sql procedure performance, have already tried dbms_profiler ... but not good, would like to hear ... is there any other/better option to work with.

Run them in development see if the performance will be acceptable, if not then you can do a TRACE/TKPROF to drill down to the slowdown.
After that you can perhaps invoke the SQL tuning facility and proceed to tune the invidual SQL commands individually.
Don't see any quick way of giving you a large overview of all the performance of all PL/SQLs on the database. This must be done on a case-by-case basis.
And that is the basic issue. You CANNOT determine performance of the code in production using development. Anyone that says it can be done, has either a perfectly static and known production environment, that is duplicated to the last byte and last h/w bolt on development. Or is a liar.
So as you need to design, work and test within the limits of development, the aims are simple. Design and write scalable and performant code. No need to be a rocket scientists or analysing tkprof traces to determine whether code is scalable and performant. One should be able to, at first look, tell that a FOR cursor loop doing DMLs inside the loop is not performant and cannot scale. Or that a procedure tasked to update almost every single row in a VLT, is a major workload that is serialised, and instead should be parallelised. So before diving into nuts and bolts of a tkprof, get the algorithms and designs right.
As for unleashing the code on production. No amount of stress testing and tuning on development is adequate to tick off the deployment checklist box that says "+code will now run just fine in production+". Which is why you need to add to the code, the ability for the code to report on what it is doing, the workloads its dealing with, the resources it has available and is using, and how fast it is dealing with the workloads.
The success of that s/w deployed to production, directly depends on how well that code is instrumented - in order to enable the code to report on problems encountered in the production environment.

PL SQL Procedure to validate the data before inserting

Hi All,
I have a PLSQL procedure that validates the data and also inserts the data into the table. That procedure must be run to validate each row to be inserted. My doubt is how to reference that procedure within the interface of ODI.
After reading some posts that mention the use of procedures, I think the best option is to call the procedure inside the knowledge module (inside a cursor that does a insert clause). Am I correct?
As the KM's do a lot of verification and use temporary tables, I don't know what are the steps to be modified. Also, I would like to know if it's necessary to modified only the IKM or the LKM too.
I'm using the IKM Oracle Incremental Update (PL SQL) and LKM Oracle to Oracle.
Thanks.
Luciene

by validating data you mean looking up some table and see if it exists?
If this is the case the you can implement this using a user function.
If validation fails then you may put a -1 into the mapping.
Then put a constraint on the target( say column is -1) and enable flow control.

How to use pl/sql procedure or function as part of validate the entity obj?

Hi,
we are migrating from oracle forms to jdeveloper 11g.
I have a req. that,i wanted to use oracle pl/sql procedure to validate a attribute in an entity created with ADF BC?
Is it possible to implement this?
And how to show the error message from pl/sql procedure?
Regards
Murali.

Hi,
It is possible by using a method validator for the entity attribute.
Create a transient attribute 'X'.
In the validation section of the attribute to be validate, choose method validator.
In the Error Message tab set error message as {0}.
Below the value for tokentoken should source.X (X is the transient attribute name)
In the java code of method validator, call the stored procedure and set the value of transient attribute X with the error message from SP.
Use setX("ErrorMessage").

How do I delete cascade with a PL/SQL procedure?

This script will create a PL/SQL procedure that deletes cascade. This is a post to contribute to the Oracle community. Take the code as is and test it before you use it in production. Make sure this is what you want.
Procedure Delete Cascade (prc_delete_cascade)
Description
=============
The principle is very simple. The procedure uses a table called TO_BE_DELETED to keep a list of records to be deleted. This
table keeps the table name and the rowid of those records that need to be deleted. The procedure also uses a function called
DELETE_BOTT_ROW which takes one record of the table and tries to delete it. If the deletion fails with a foreign key constraint
violation, the function parses the SQL error message (SQLERRM) to get the name of the constraint. With the name of the constraint,
the function finds the name of the child table, all the child records that have references to the parent table primary or unique key,
and the parent key primary or unique key column name. Once the child records of the failed delete are identified, the function takes their table name and rowids
and records them into the TO_BE_DELETED table by inserting records of their table name and their rowids. Al the records inserted also contain the level (which
is 1 for the original records, 2 for child records, 3 for granchild records, etc.) and the sequence number of the order in wich they
are recorded. This way, when the function picks up a record to be deleted, it takes the one with the highest level and the highest
inserted sequence, or the "bottom" record. Once all the child records of the failed delete are appended to the TO_BE_DELETED table, it calls itself
recursevely, and the function takes the record at the "bottom" of the table and tries to delete it. If it succeeds, it calls
itself recursevely to delete the next record. If it fails, it goes and finds the child records as described before and once they are
inserted into the TO_BE_DELETED table, it calls itself again recursevely to try to delete again the "bottom" record. All records
that are successfully deleted are flagged as deleted usig the flag_del column so they are not pickt up again. Once all the (parent,
child, grandchild, etc.) records are deleted, the procedure ends without commiting, giving the option to the user to commit or
rollback deletions. The table TO_BE_DELETED is, at the end of the procedure, a list of all the records that were deleted, including their table names
and the order in with they were deleted. The user then can review its content and decide to commit or rollback.
Restrictions
============
1. Single tables only. The procedure only takes one table name and a WHERE clause to identified the records to be deleted.
2. Single columns only. Ther procedure only works with single-column primary, unique and foreign key constraints.
3. Single schema only.
4. Unpredictable results with circular references.

Interesting.
I see a few areas where this could be useful. Elimiating specific test records from a Test DB for example.
Some comments:
<li>Since this is a recursive logic you must add a stop criteria. In this case I would add a max iteration variable. If that one is reached, raise an error message and let the procedure stop with that error.</li>
<li>The when others exception at the end should be removed completely</li>
<li>The when others exception in the middle should be replaced by a specific exception that handles the -2292 error</li>
<li>A list of tables where no record should be deleted could be usefull. If the logic would encounter such a table, it should also stop. This would be to prevent that data from some system critical tables could be deleted per accident.</li>
<li>The reference from the FK constraint to the PK constraint should include the table name and if possible the owner (as long as you use user_* views the owner is always the same. But we could extend this to the ALL_* views). I never met a system where different tables have the identical FK constraint names, however just make this fool proof.</li>

Obtaining HTML page by issuing a call from a PL/SQL procedure

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.

Read from Page Approval List Table in a PL/SQL procedure

Need help, I am new to OA Framework.
We have a requirement to validate the added requisition Approvers against some criteria.
The Approvers are added using Add approvers on the Requisition Creation page.
The source code shows: ApproverListRn.ApprListTable as the name of the table list which holds the approver names.
1) Is there a way to read the data from ApproverListRn.ApprListTable in a PL/SQL procedure?
2) How and when does this list of approvers get added to the po_approvallist_headers table? which package is used?
Please any help is greatly appreciated.
Thanks

1) Is there a way to read the data from ApproverListRn.ApprListTable in a PL/SQL procedure?
Using OAF, you can read the value from the table and through OracleCallableStatement you can call a pl/sql procedure passing the read value.2) How and when does this list of approvers get added to the po_approvallist_headers table? which package is used?
This is page and code specific. You will have to debug and find out.--Shiv

Problem calling PL/SQL procedure from Workflow function activity.

Hi,
I am trying to call a PL/SQL procedure from within my workflow activity.
While I am able to execute the procedure through SQLDeveloper, the workflow function does not seem to call it.
It seems that custom PL/SQL procedures have to conform to certain standards to be called within workflow applications. I have written my procedure to conform to those standards (referred to the example workflows).
Could someone please help me with it?
Thanks and regards.

Best Procedure to Validate data in Xlsx

Hi All,
I have a requirement where we have to build an ETL to load xlsx files into my SQL Database. Before loading to my target table i would need to validate the data.
I have Two Procedures to validate the data
1) Import every thing into SQL, validate it load to Target Table
2) Validate the xlsx in ssis using the data conversion task, conditional split task etc.
My Question is which is the best procedure to validate.
I have 15 columns (Mostly numeric,date,money) and two validation scenarios check for null? check the length?
Thanks in Advance.
kuk

I would prefer doing this in SQL unless there are any complicated steps like RegexMatch which may be much better dealt with using SCript Task in SSIS by using .NET functions.

Checking the performance of Pl/SQL Procedure

I have a PL/SQL procedure of 10,000 lines, & I dont have any Tool of performance checking only thing I have is SQL Client & database how whould I check the performance of the procedure

Why do you want to check the performance? Have you indentified a specific problem?
It is not easy to to "simply check the performance" of code. Let's say it has an elapsed execution time of 90 seconds. What does that tell you? Fast? Slow? Average? What does 90 seconds tell you about the resource utilisation? Nothing much - are resources being red lined for those 90 seconds or not?
So unless there is a specific performance problem that has been diagnosed, e.g. the process uses too much PGA memory, you cannot really identify a performance problem.
What you can do is use DBMS_PROFILE (Oracle supplied PL/SQL package) to profile the execution time of the code. This will tell you which pieces of the code are slower than others. This allows you to focus on area where possible optimisation can reduce overall execution time - or it could be that these areas are already optimised.
What you can miss with this approach is a small loop that takes a few seconds to execute - less than 1% of the total elapsed execution time. But this loop can be very wrong and should have taken a few millisecs to do. A month later running against big production data volumes, this loop's runtime changes into minutes and over 50% of the overall execution time of the process.
You may look at the FOR CURSOR FETCH loop and see that it has been optimised. Great, so you move on to look at the next piece of code. Only, there are other loop constructs that can be exponentially faster than this loop - like a bulk processing loop instead.
You may look at a SQL that seems slow, but after investigation it seems to be optimal. And it could well be. But performance can be increased by 80% by not touching the SQL and instead changing the table's structure from a normal heap table to a ranged partitioned table.
The bottom line is that there are no magic wands and crystal balls that can be used to check performance and tell you that "abc" is wrong. Tools can tell you what is slow, what is resource expensive - but it cannot tell you whether the code does what it is suppose to do in the best and most effective way. Only a programmer can. Which means that things like code reviews, design walk-thru's and so on, are critical pieces to ensure that the code is performant and can scale.

Function Activity based on PL/SQL procedure

Hi All
I have a function activity in a workflow, which is based on a PL/SQL procedure. When I make any changes to the package or the stored procedure, workflow gives "Could not find package or program unit" error, even though the status of the package is valid in database.
Essentially everytime I re-apply the package, I get this error. I then drop the package and then recreate it. Even then the error is not resolved immediately. Does this requires Apache bounce? Is there any other step that I am missing when we make changes to database packages that are based on workflow activities?
It would be of great help if someone can throw light on the above.
Many thanks in advance
cheers

Hi,
Have you tried searching this forum for the error message? There are plenty of posts about it here, on the WorkflowFAQ forum, and also in my blog about the issue, why it happens, and how you can avoid it.

Simple stored procedure to validate multiple customer account numbers without defining a type

I would like to create a simple stored procedure to validate up to 1-10 different customer account numbers at a time and tell me which ones are valid and which ones are invalid (aka exist in the Accounts table). I want it to return two columns, the
account number passed in and whether each is valid or invalid.
The real catch is I don't want to have to define a type and would like to do it with standard ANSI sql as my application has to support using multiple dbms's and not just sql server. Thanks!

Hi again :-)
Now we have the information to help you :-)
I write the explanation in the code itself. Please read it all and if you have any follow up question then just ask
This solution is for SQL Server and it is not fit for all data sources. Please read all the answer including the comments at the end regarding other data sources. Basically you can use one String with all the numbers seperated by comma and
use a SPLIT function in the SP. I give you the solution using datatype as this is best for SQL Server.
In this case you should have a split function and this is very different from one database to another (some have it build it, most dont)
------------------------------------------------------------------- This part call DDL
CREATE TABLE Accounts(
AccountNbr [char](10) NOT NULL,
CustomerName [varchar](100) NOT NULL,
CONSTRAINT [PK_Accounts] PRIMARY KEY CLUSTERED ([AccountNbr] ASC)
GO
------------------------------------------------------------------- This part call DML
INSERT INTO Accounts(AccountNbr, CustomerName)
SELECT
cast(cast((9000000000* Rand() + 100000) as bigint ) as char(10)) as AccountNbr
,SUBSTRING(CONVERT(varchar(255), NEWID()), 0, 11) as CustomerName
GO
------------------------------------------------------------------- Always I like to check the data
SELECT * from Accounts
GO
/* Since you use random input in the DML and I need to check valid or in-valid data,
Therefore I need to use this valid AccountNbr for the test!
AccountNbr CustomerName
6106795116 E689A83F-A
-------------------------- Now we sytart with the answer ------------------------------------
-- You should learn how to Create stored Procedure. It is very eazy especially for a developr!
-- http://msdn.microsoft.com/en-us/library/ms345415.aspx
-- dont use the SSMS tutorial! use Transact-SQL
-- Since you want to insert unknown number of parameters then you can use Table-Valued Parameters as you can read here
-- http://msdn.microsoft.com/en-us/library/bb510489.aspx
-------------------------- Here is what you looking for probably:
/* Create a table type. */
CREATE TYPE Ari_AcountsToCheck_Type AS TABLE (AccountNbr BIGINT);
GO
/* Create a procedure to receive data for the table-valued parameter. */
CREATE PROCEDURE Ari_WhatAccountsAreValid_sp
@AcountsToCheck Ari_AcountsToCheck_Type READONLY -- This is a table using our new type, which will used like an array in programing
AS
SET NOCOUNT ON;
SELECT
T1.AccountNbr,
CASE
when T2.CustomerName is null then 'Not Valid'
else 'Valid'
END
from @AcountsToCheck T1
Left JOIN Accounts T2 On T1.AccountNbr = T2.AccountNbr
GO
-- Here we can use it like this (execute all together):
/* Declare a variable that references the type. */
DECLARE @_AcountsToCheck AS Ari_AcountsToCheck_Type;
/* Add data to the table variable. */
Insert @_AcountsToCheck values (45634),(6106795116),(531522),(687),(656548)
/* Pass the table variable data to a stored procedure. */
exec Ari_WhatAccountsAreValid_sp @AcountsToCheck = @_AcountsToCheck
GO
------------------------------------------------------------------- This part I clean the DDL+DML since this is only testing
drop PROCEDURE Ari_WhatAccountsAreValid_sp
drop TYPE Ari_AcountsToCheck_Type
-------------------------- READ THIS PART, for more details!!
-- validate up to 1-10 different customer account numbers at a time
--> Why not to validate alkl ?
--> SQL Server work with SET and not individual record. In most time it will do a better job to work on one SET then to loop row by row in the table.
-- tell me which ones are valid and which ones are invalid (aka exist in the Accounts table)
--> If I understand you correctly then: Valid = "exist in the table". true?
-- I want it to return two columns, the account number passed in and whether each is valid or invalid.
--> It sound to me like you better create a function then SP for this
-- The real catch is
-- I don't want to have to define a type
--> what do you mean by this?!? Do you mean the input parameter is without type?
-- and would like to do it with standard ANSI sql
--> OK, I get that you dont want to use any T-SQL but only pure SQL (Structured Query Language),
--> but keep inmind that even pure SQL is a bit different between different databases/sources.
-->
-- as my application has to support using multiple dbms's and not just sql server.
--> If you are looking a solution for an applicatin then you probably should use one of those approach (in my opinion):
--> 1. You can use yourown dictunery, or ini file for each database, or resources which is the build in option forwhat you are looking for
--> You can create for each data source a unique resources
--> If the queries that need to be execut are known in advance (like in this question), then you can use the above option to prepare the rigt query for each data source
--> Moreover! one of those resources can handle as general for "other ources"
--> 2. There several ORM that already do what you ask for and know how to work with different data sources.
--> You can use those ORM and use their query languge instead of SQL (for example several work with LINQ).
I hope this is helpful :-)

PL/SQL Procedure and Java

Hi All,
I am working on a Data Warehousing Product and generating Web Reports.
These Web Reports are JSPs.
The basic architechture used for this is :
1. Get the inputs required for Report Generation through a Web GUI
2. Validate and Process (If Valid) the inputs so that it can be applied on the Data in the DB to fetch appropriate information.
3. The Data from the DB is retreived in the form of PL/SQL Procedures, which take the Processed information from Step 2 as Input and give the Output in the form of REF CURSORS.
Note: There are a many PL/SQL Procedures that are being executed, based on the configuration the Client has set. This configuration enables the Client to set the columns he wants to see in the Web Reports. This configuration is set before the Reports are run.
4. A call is made from Java to Oracle, each time a PL/SQL Procedure need to be executed. The REF CURSOR received as an Output from the PL/SQL Procedure is processed.
5. The next PL/SQL Procedure is called (if existing), else the Processed Data (from REF CURSOR Output) is displayed in the JSP as Web Reports.
The issue with above architechture is the PERFORMANCE.
I would like to know:
- The various ways in which data can be EFFICIENTLY & QUICKLY retrieved from PL/SQL Procedure in Java.
- Are there any APIs that improve the Java-Oracle Data Fetch Efficiency
- Is there any Java Framework available that can be used to increase the spped of Web Report generation.
- Do you suggest any changes in the above mentioned architechture, that make this work a Sweet Sixeen Year olg guy! ;)
- In general, any input that can increase the Speed of Web Report Generation.
Kindly let me know if I have not been clear at any point, so that I can re-explain the same more clearly.
And the most important thing, kindly scrap down your thoughts about the same.
Thanks a lot in advance for your VALUABLE INPUTS.

Unable to capture the parameter values from a PL/SQL procedure

hi.
i'm trying to capture the parameter values of a PL/SQL procedure by calling inside a anonymous block but i'm getting a "reference to uninitialized collection error" ORA-06531.
Please help me regarding.
i'm using following block for calling the procedure.
declare
err_cd varchar2(1000);
err_txt VARCHAR2(5000);
no_of_recs number;
out_sign_tab search_sign_tab_type:=search_sign_tab_type(search_sign_type(NULL,NULL,NULL,NULL,NULL));
cntr_var number:=0;
begin
     rt843pq('DWS','3000552485',out_sign_tab,no_of_recs,err_cd,err_txt);
     dbms_output.put_line('The error is ' ||err_cd);
     dbms_output.put_line('The error is ' ||err_txt);
     dbms_output.put_line('The cntr is ' ||cntr_var);
     for incr in 1 .. OUT_SIGN_TAB.count
     loop
     cntr_var := cntr_var + 1 ;
Dbms_output.put_line(OUT_SIGN_TAB(incr).ref_no||','||OUT_SIGN_TAB(incr).ciref_no||','||OUT_SIGN_TAB(incr).ac_no||','||OUT_SIGN_TAB(incr).txn_type||','||OUT_SIGN_TAB(incr).objid);
end loop;
end;
Error is thrown on "for incr in 1 .. OUT_SIGN_TAB.count" this line
Following is some related information.
the 3rd parameter of the procedure is a out parameter. it is a type of a PL/SQL table (SEARCH_SIGN_TAB_TYPE) which is available in database as follows.
TYPE "SEARCH_SIGN_TAB_TYPE" IS TABLE OF SEARCH_SIGN_TYPE
TYPE "SEARCH_SIGN_TYPE" AS OBJECT
(ref_no VARCHAR2(22),
ciref_no VARCHAR2(352),
ac_no VARCHAR2(22),
txn_type VARCHAR2(301),
objid VARCHAR2(1024))............

We don't have your rt843pq procedure, but when commenting that line out, everything works:
SQL> create TYPE "SEARCH_SIGN_TYPE" AS OBJECT
2 (ref_no VARCHAR2(22),
3 ciref_no VARCHAR2(352),
4 ac_no VARCHAR2(22),
5 txn_type VARCHAR2(301),

How to call a PL/SQL procedure from a Java class?

Hi,
I am new to the E-BusinessSuite and I want to develop a Portal with Java Portlets which display and write data from some E-Business databases (e.g. Customer Relationship Management or Human Resource). These data have been defined in the TCA (Trading Community Architecture) data model. I can access this data with PL/SQL API's. The next problem is how to get the data in the Java class. So, how do you call a PL/SQL procedure from a Java program?
Can anyone let me know how to solve that problem?
Thanks in advance,
Chang Si Chou

Have a look at this example:
final ApplicationModule am = panelBinding.getApplicationModule();
try
     final CallableStatement stmt = ((DBTransaction)am.getTransaction()).
                                                                                     createCallableStatement("{? = call some_pck.some_function(?, ?)}", 10);
     stmt.registerOutParameter(1, OracleTypes.VARCHAR);
     stmt.setInt(2, ((oracle.jbo.domain.Number)key.getAttribute(0)).intValue());
     stmt.setString(3, "Test");
     stmt.execute();
     stmt.close();
     return stmt.getString(1);
catch (Exception ex)
     panelBinding.reportException(ex);
     return null;
}Hope This Helps
