Print TopLink SQL Queries in JDev

Hi,
Is there a way to log the TopLink SQL Queries using log4j. Want to log the exact sql that is executed when an action is taken from ADF Page and TopLink query is executed. Need it for debugging purpose from JDeveloper are there any settings.
Thanks

Hi,
I think this question is independent of ADF, which is why I think that this is a question for the TopLink forum

? in SQL Queries and not using prepared statements

Using EclipseLink 1.1.1
Prepared Statements are disabled
In our production server something went wrong and one of our Read Queries started erroring. A DatabaseException was thrown and we log the "getQuery.getSQLString()" statement. We found this query in the logs:
SELECT t1.ID, t1.NAME, t1.DESCRIPTION, t1.EXTREFID, t1.STYLESHEET, t1.DDSVNVERSION, t1.FIRSTNAME, t1.LASTNAME, t1.EMAILADDR, t1.PHONENUMBER, t1.ADDRESS, t1.ADDRESS2, t1.CITY, t1.STATE, t1.POSTALCODE, t1.COUNTRY, t1.ADMINACCTNAME, t1.HASDOCUMENTS, t1.HASTIMEDNOTIFICATIONS, t1.STATUS, t1.ENTRYDATE, t1.EVALEXPDATE, t1.LASTREMINDDATE, t1.FULLUSERS, t1.LIMUSERS, t1.REQUSERS, t1.ISENTERPRISE, t1.EXPDATE, t1.ISDISABLED, t1.DISABLEDDATE, t1.NEEDLICENSEAGREEMENT, t1.ISWARNINGDISABLED, t1.LOCALE, t1.TIMEZONE, t1.CURRENCY, t1.DOMAIN, t1.DOCUMENTSIZE, t1.EXTRADOCUMENTSTORAGE, t1.ONDEMANDOPTIONS, t1.SSOTYPE, t1.RESELLERID, t1.ACCOUNTREPID, t1.LASTUSAGEREPORTDATE, t1.NEXTUSAGEREPORTDATE, t1.USAGEREPORTATTEMPTS FROM T_SSOOPTIONS t0, T_CUSTOMERS t1 WHERE *((((t0.SSOENABLED = ?) AND (t1.SSOTYPE IN (?, ?))) AND (UPPER(t1.DOMAIN) = ?)) AND (t0.CUSTOMERID = t1.ID))*
Notice the values weren't entered into the where clause. We had to bounce the application to fix the problem. I've never seen this before. I've added more debugging statements to the code - so if this happens again in the future I'll have more information to report on. In the mean time I'm wondering if anyone else has every seen a problem of this nature.

Database error due to invalid SQL statement.
I don't have a stack, we were catching the exception and not printing the stack :(
Like I mentioned in my first post, I added more debugging code (e.printStackTrace()). I understand this is hard to track down without more information. I was just hoping you guys had seen something like this before and had any insight. Like I mentioned before: this is on our production server. I've never seen this type of error before. That particular server (we run in a cluster mode) had been up for several days and then started generating that error. IT bounced the node and everything went back to normal. We have been using toplink for about 5 years now and have never seen this problem, until August 3rd 2009. The only thing that has changed recently is our migration from toplink 10 to EclipseLink. I was wondering if anyone knows if anything had changed in EclipseLink/toplink 11 with the generation of SQL queries.
I'll keep looking. There is more debugging code in there now. Since the error was "Database error due to invalid SQL statement" this implies the SQL was generated, exited that part of the code and was sent to the db where it failed. I'm afraid the printStackTrace won't help if this error happens again.

Error while running the sql queries in unix as cron job..

Hi,
I've configured some sql queries to run as cronjob from unix,i'm able to excute all the sql queries with out any error,after all the queries are executed,I'm getting the following error message.
ORA-00600: internal error code, arguments: [4080], [1], [131], [], [], [], [],
Could any one advise me why this error is being thrown?
How to avoid this error?
Thanks,
Anil

Are you running these queries through TopLink?
If so, the error seems to be occurring on the database, when the query is being executed.
I have never seen that error before. Performing some websearches it seems to be a general database error, potentially something to do with synchronization. Sorry I can't be of more help, perhaps the database forum can provide more insight...

Storing SQL queries in database itself.

I want to store SQL queries in 9i database itself so that I just need to pass the parameters from VB.NET front end and the query will execute. How can I do this?

Possibly make use of Stored packages/procedures/functions?
Back in 97/98 I had worked with VB (version 6 at that time) application for which I had written stored procedures to do exactly that... (except for select) VB application would pass parameter values to these procedures for doing inserts/updates/deletes. No application user was given direct insert/update/delete privileges.
Also I had triggers written for each of the table involved to keep footprint (user id and date/time) for last update/insert for each of the row.
I don't remember for sure if the application deleted rows from the DB. I think the application handled delete by actually updating a flag (active/inactive) again with a foot print so that you can track back the "deletes".
my 1/2 cent worth of thought

View SQL queries during runtime

In the Jdev tutorials I noticed the running tab displaying the sql queries that are being run in the application. How can I turn this on? Using 10.1.3.0.4
thanks

Please see sections "5.5.3.2 Enabling ADF Business Components Debug Diagnostics" , "8.3.4 Debugging the Application Module Using the Business Components Tester", and "Chapter 24 Testing and Debugging Web Applications" of the ADF Developer's Guide for Forms/4GL Developers on the ADF Learning Center at http://www.oracle.com/technology/products/adf/learnadf.html for more useful information on this.

Recursive Java programming method for executing recursive SQL queries

Anybody has a Java/JDBC example method to execute recursive SQL queries and print results? The method has to work for any number of queries and levels and the first query passes the parameter to the second query.

Guys, the problem what I am trying to solve is much more complex and I don’t think SQL level recursion is enough. I am looking for Java solution with SQL queries in it to make it more flexible and DB independent.
If you want to do recursion in SQL then it has nothing to do with Java.
And if you want to do recursion in Java then the idiom itself has nothing to do with SQL.
Other than that you have provided enough detail for anyone to even guess at what you are asking.
As a start I am not even sure that you understand what recursion is nor how JDBC works. (But it could be that you are using the terms to mean something else.)
And looking at your original post it could be nothing more than that you are looking for a design pattern - perhaps the interpreter.

How to print Integrity sql in the preparedstatement?

How to print Integrity sql in the preparedstatement?
Connection conn = null;
String sql = "select * from person where name=?";
PreparedStatement ps = conn.prepareStatement(sql);
ps.setObject(1, "robin");
ps.executeQuery();
i'm wants print Integrity sql.
For example:select * from person where name='robin'
How should I do?
thanks a lot!

PreparedStatement doesn't offer methods for that. You can write your own implementation of PreparedStatement which wraps the originating PreparedStatement and saves the set* values and writes it to the toString().
If needed, myself I just print the sql as well as the values-being-set to the debug statement.Logger.debug(query + " " + values);

Erratic Report Region Behavior with Dynamic SQL Queries

I'm running HTMLDB v 1.5.1.00.12 and I've noticed some odd behavior with report regions using dynamic SQL queries. Every so often, our testers will run a page containing a dynamic sql report region and get the following error, (despite the fact the query was working only moments ago and no other developer has touched it):
ORA-06502: PL/SQL: numeric or value error: character string buffer too small
or sometimes
failed to parse SQL query:ORA-01403: no data found
The only solution I've found so far is to:
1) Make a copy of the failed report region.
2) Disable or delete the original failed report region.
The new copy of the report region runs without issue.
My search of the forums turned up the following two threads, but neither provided me with a clear explanation of the cause, and how to avoid it:
ORA-06502:PL/SQL: numeric or value error: character string buffer too small
Re: Import Export Error (ORA-06502)
The columns being returned are below the 4000 character limit, and the rows being returned are far less than 32k in size.
Could this have anything to do with the way HTMLDB is internally storing the PL/SQL used to generate the dynamic SQL Query? Is there any known issue related to this with that version of HTMLDB?
This problem occurs without any discernable pattern or consistency, making it hard to determine where I should focus my efforts in tracking down the cause.

Hi all,
My report seems to be behaving correctly once i set it to "Use Generic Column Names (parse query at runtime only)" :)
Cheers,
Joel

How to print my SQL Report

Hi all,
I want to print the SQL Report returned from a simple query returning 5 columns, and n number of rows. I don't want to use Oracle BI Publisher as its needs licence to work with. Can anyone let me know which software i can use with my application express. Moreover, do let me know the steps to integrate it in Application Express and finally to an SQL Report. Thanks a lot.
I am using Oracle Application Express 3.2 + 10G XE
With Regards,
Krishna Vashishtha

Hi Krishna,
"Report printing is currently not available, there is no print server configured."
For the above error, run the APEX Administration application and have a look at:
--Manage Service
----Instance Settings
------Report Printing
This might get you started with the built in functionality (I am not sure about this but have a look). You will also probably need to set up this area for FOP and JASPER.
Sorry, I do not know which is better regarding FOP or JASPER. I have no personal experience with either of them. Perhaps you could try the "Ask Tom" web site. It might have a few hints.
Can anyone else jump into this one with a pointer to a tutorial or two?
Cheers,
Patrick

Need help in SQL Queries using GUI controls or variables

Hello, all
I have a big problem (I have already had with Visual Basic a few mounths ago) with Java while writing my SQL Queries.
I would like to know how I must do to use variable data or GUI control data in my SQL Query to select only some records.
Here, my first Query that works without any problem (no WHERE clause !!!) :
Statement requeteBedes = connectBedes.createStatement();
ResultSet resultatSeries = requeteBedes.executeQuery("SELECT * FROM Series");
initComboBoxSeries(resultatSeries);the method "initComboBoxSeries" fills a JComboBox with all the names of the series in my database.
Here comes my problem.I would like to use the value of the selected "series" in the JComboBox to search in another table of the same Database. I made another statement but it returns a Null ResultSet :
ResultSet resultatSearchAlbumsFromSeries = requeteBedes.executeQuery("SELECT * FROM bandes_dess WHERE ser_nom = '" + strComboBoxSeriesSelected + "' "); The variable strComboBoxSeriesSelected contains the value of the selected line in the combobox with all the series, filled after the first query that is here above and that works very well.
Could some one help me and tell me how I must use variables or GUI controls values in my SQL Queries or tell me if there is a place where I could find an explanation of that kind of problems (like more "advanced SQL Queries", as the ones currently used in all the Learning Java 2 books)
Thank you all for your help.
Christian.

executeQuery() will never return null. At least that's what the spec says. You are probably catching an exception (probably a syntax error caused by a single quote in strComboBoxSeriesSelected) and ignoring it. Or do you mean the ResultSet contains no rows?
Anyway, to use parameterized queries, take a look at PreparedStatements. Your code should look like this using PreparedStatement:Statement requeteBedes = connectBedes.prepareStatement("SELECT * FROM bandes_dess WHERE ser_nom = ?");
requeteBedes.setString(1, strComboBoxSeriesSelected);
ResultSet resultatSeries = requeteBedes.executeQuery();Alin.

How to get the SQL queries based on SQL_ID.

Hi Experts,
I want to get the SQL queries based on SQL_ID.
I have tried the following query,but I am not getting full query.
[code]SET linesize 132 pagesize 999
column sql_fulltext format a60 word_wrap
break on sql_text skip 1
SELECT   REPLACE (TRANSLATE (sql_text, '0123456789', '999999999'), '9', ''),sql_id
FROM   dba_hist_sqltext s
WHERE   s.sql_id = '7tvurftg8zryb';[/code]
One of my friend said use grid to get full query text.
Can you please help me how to use grid ,else any other method to get the full query based on SQL_ID.
Please help me.
Thanks in advance.

You have these many options to set, if sql_text is really huge. But better use a tool(TOAD) as it's really helpful and easy to use instead! (See my previous comment).
column sql_text format A10000
set echo off
set head off
set feed off
set verify off
set termout off
set lines 10000
set long 1000000
set trimspool on
set pages 0
Thanks!

Developing portlets for dummies (sql queries)

Hello, I've been trying to build a dynamic menu. First I went with just plain old plsql: i created a function in the portal schema that returns an unordered, nested list of the pages in my pagegroup and called that function in a regular pl/sql item on my portal page. I did this by querying the wwpob_page$ table and that went just great in my test&development setup (of which I am the admin of course :))
Then I realized that since I'm not an administrator of the server hosting our portal and I only have very limited privileges (I am only a page group administrator) I will probably not be allowed to utilize this function nor will they agree to install it in the portal schema, and I decided I should build a portlet that does the same thing (so it can be registered and so on, and so it can use the synonyms and tools that are available to registered providers). There already is such a portlet (and provider) registered for use in the target portal, but I don't like it because i uses tables and hard-coded styles so I will cook my own, better version. :)
So I downloaded an example portlet and am getting the hang of it, but now I just can't for the life of me figure out how to enable any sql-queries. I have run the provsyns-.sql script, logged in as test_provider/portal and installed my portlet-package as test_provider user. I can see the available pl/sql packages in Toad, but there are no tables or views for me to to see. That means I can't query the portal tables that I need to.
edit: ok, stupid user error; I suck at using Toad, so I was looking at the wrong schema altogether :D So now i see the public views and packages, so forget that bit of the question.
But still, I cannot see even wwsbr_all_folders -view, much less the wwpob_page$ -table. I cannot see any way to find the pages that are in my page group. Somehow it must be doable, right?
Have I done something wrong, missed a step in enabling my test-provider / schema perhaps? I don't really know what I'm doing, but I followed instructions here: http://home.c2i.net/toreingolf/oracle/portal/my_first_plsql_portlet.htm (excellent instructions, thanks!)
So should my portlet be able to access those tables or not? How the heck has the third partly portlet maker done it?
i'm on OracleAS Portal 10g Release 2 (10.1.4)

i see your perspective now. and let me give a perspective to my first reply too.
what i proposed to you was the answer of what i quoted in the message. that is, why didn't you see those views in the new schema you created! and it is still ok but it is done in the portal schema for which you should have privielges too and i assumed you had. my mistake!
now, i can relate your privacy concerns with your earlier message:

- by downloading an example portlet, you probably mean you created a new schema. because provsyns work on a schema.
- if you are not the administrator of the portal, and may not be able to access some portions of the portal, it means that you do not use the portal user (the user which serves as the owner of the portal schema).
- now, your plan to create a new schema and give those privielges would still not work. because, by creating a new schema you cannot sneak in to the oriignal portal schema if you do not have privileges to do it. obvious, right? otherwise, it would be a vulnerability of the software that you can see what you are not allowed to see by creating a new schema.
- however, there is a bright side here. the views give records based on your privileges.
- so if your administrators have generated them already or if they generate on the original portal schema, then you may see the pages and items that you have privileges to see and no more.
so now, you may ask the administrators if they have already done it, and if not, then if they would be willing to do it.
hope that helps!

Ruby code for sql queries

Hello everybody,
First off, let me apologize if my inquiry does not belong on this forum. I am confident however, that someone here has had experience with this since Oracle and ruby on rails/ruby are used frequently. My fingers are crossed, here's is my problem:
I am currently working on a database system that utilizes ruby on rails
with a oracle database. Here's the situation:
the ruby on rails web application is up and running;
my oracle database is full of tables that are populated with data;
there is a successful connection between rails and my oracle database;
however, what isn't finished is I currently have data mining queries in
sql (eg. find minimum time someone has been employed = "Select
min(time) from table...etc") and what I need to do is write one ruby
program for each of my sql queries so that the ruby program:
1) connects to the oracle database each time the query is called
2) runs the sql query on the oracle database
3) takes the results from the query and returns them in an array or
something of that nature (so that I can use the results in an html file
on the ruby on rails web application).
Again, I apologize if this question does not belong on this forum. If someone however has experience with this could you please give me example code of what this would look like (using different sql queries). Thank you

I apologize if this question does not belong on this forum. OTN does have a forum dedicated to Ruby/Ruby On Rails. I admit it doesn't seem to get much traffic. I think that's because most people working with Ruby tend to go for F/OSS products.

SQL queries parser.

Hello,
I have quite strange question related to my research.
Probabley within Oracle DB there is some dynamic library which is parsing SQL queries,
for example.
SELECT * FROM schema.table which is able to extract informations from SQL listed above that we want to display all columns from selected table.
When this construction is valid ( SQL standard ) the next step is verification the object existence in DB. It means
that there are two separated actions which are analyzing queries.
I need only first part of that process, which will give me informations about all object used in SQL query
is it possible to accomodate that internal parser witin stand alone middleware like Weblogic Event Server ?
I can do it with regular expression patters, but it's not going to be fast and effective for subqueries and all advanced
constructions for DHW like MODEL, etc.
Thank You,
R.

SQL queries in JSP

Does anyone know how to create a JSP which allows the user to input data into a simple database and then allow the user to input SQL queries? I can do this in a servlet but must hard code the query. It would be great to be able to type in differnet queries to see the results.
Thanks
Michael

hai,

     st.setString(1,email_address);
     st.setString(2,query_text);
