TNS error on sql query

Hi,
Somebody please explain why it happens when I run some queries. This was in the session log of Informatica tool. Following is the desc...
ORA-12612: TNS:connection is busy
Cause: Attempted operation failed because it conflicts with an ongoing action or status of the connection.
Action: Not normally visible to the user. For further details, turn on tracing and reexecute the operation. If error persists, contact Worldwide Customer Support.
Thanks all.

Zero seems an awfully low setting - you'd be generating constant network traffic. The documentation recommends 10 minutes between checks.
Do you really need to do this dead session checking at all? Unless you are seriously short of resource I would suggest you remove the parameter entirely from the SQLNET.ORA file. You can always get the DBA to check explicitly for non-active sessions (DBAs just sit around all day doing nothing, they would relish this additional task :P ).
Cheers, APC

ERROR: Updatable SQL Query already exists on page 20.

Hello,
I created a tabular form, then added a where clause and started getting the following error:
Error in mru internal routine: ORA-20001: no data found in tabular form
So I deleted all components of the tabular form (region, buttons, branches and process) and started building it again from scratch. This is a strategy that has worked for me a number of times in HTML DB. Unfortunately now I get the following error when trying to build a new tabular form:
Updatable SQL Query already exists on page 20.You can only add one updatable SQL query per page. Select a different page.
What is the logic that throws this error. I'm 99% convinced I've cleared the page of any updatable SQL, is there something on the application level I should also clear out?
Thanks!

Ignore this, problem solved. It seems I do have SQL reports that are marked as updatable even though they are just plain reports.
Sorry.

Error in SQl Query - SQl Command not properly ended

Hi All
I have this SQL query that returns the following error when I run it in TOAD:
SELECT
VC.CAMPAIGN_NUMBER,VC.CAMPAIGN_TITLE,VC.CAMPAIGN_DESC,
VCV.START_DATE, VCV.END_DATE,VC.CAMPAIGN_TYPE,VC.APPLICABILITY,

AND SYSDATE BETWEEN VCV.START_DATE AND VCV.END_DATE
AND SYSDATE BETWEEN VC.START_DATE AND VC.END_DATE)
A ORDER BY A.CAMPAIGN_PRIORITY DESC, A.END_DATE
The error is:
SQl Command not properly ended
Any help is highly appreciated. Thanks

Thanks a lot to everyone. It helped me run the query without any problem. Now I have another issue. This may not be the right place to post this question, I think.My apologies for that. The problem is, Weblogic posts an error as follows:
java.sql.SQLException: ORA-00923: FROM keyword not found where expected
I am wondering if this is an Java related error or an SQL related error.
Well, I am using the SQL Statement which you helped debug, and it is inside something called "XXSQLConstants.java consisting of the following SQL statement:
public static final String XX_ALL_CAMPS_SELECT = "SELECT * FROM" +
     "(SELECT vc.campaign_number, vc.campaign_title, vc.campaign_desc, vc.start_date," +
     "vc.end_date, vc.campaign_type, vc.applicability, vc.campaign_priority" +
"FROM vm_campaign vc" +
"WHERE vc.applicability = 'Y'" +
"AND vc.country_code = ? " +
"AND vc.language_code = ? " +
"AND vc.campaign_type = ? "+
"AND SYSDATE BETWEEN vc.start_date AND vc.end_date" +
"AND NOT EXISTS (" +
"SELECT 'X'" +
"FROM vm_campaign_vin vcv" +
"WHERE (vcv.vin = ? " +
"AND vcv.campaign_number = vc.campaign_number" +
"))" +
     "UNION" +
     "SELECT vc.campaign_number, vc.campaign_title, vc.campaign_desc," +
     "vcv.start_date, vcv.end_date, vc.campaign_type, vc.applicability," +
"vc.campaign_priority" +
"FROM vm_campaign_vin vcv, vm_campaign vc" +
"WHERE vcv.vin = ? " +
"AND vcv.campaign_number = vc.campaign_number" +
"AND vc.country_code = ? " +
"AND vc.language_code = ? " +
"AND vc.campaign_type IS NULL" +
"AND SYSDATE BETWEEN vcv.start_date AND vcv.end_date" +
"AND SYSDATE BETWEEN vc.start_date AND vc.end_date)";
The SQl runs fine when tested (well, it does not return any data for the rows returned, but there are no errors), but in my application server I get the following error (pointing out the same SQL code pasted above:
java.sql.SQLException: ORA-00923: FROM keyword not found where expected
Any suggestions? Thanks in advance. I appreciate all replies

Odd Variable Substitution Error in SQL Query

I'm trying to finish up an application but one goofy error is
throwing me for a loop. The error complains about my SQL syntax on
the line containing "#filelist_sql#" near the bottom of the query,
but when I output the SQL and run it in phpMyAdmin, it works fine.
Thanks in advance for any help provided. I think I've just
been looking at this way too long.
Code follows:

Thanks for the quick assistance, Azadi. I am finding the same
bit of strangeness occurring just a bit earlier in my code.
The application complains about the SQL syntax near
"#grouplist_sql#" in the attached code.
After the code gets processed (using '11' for
sql_find_lists.id), the SQL looks like:
SELECT DISTINCT file_id FROM grouplists_to_files WHERE
grouplist_ids = '11' OR grouplist_ids LIKE '11,%' OR grouplist_ids
LIKE '%,11' OR grouplist_ids LIKE '%,11,%'
Hopefully someone can spot something else brilliantly obvious
that is wrong here.

Error in sql query as "loop has run more times than expected (Loop Counter went negative)"

Hello,
When I run the query as below
DECLARE @LoopCount int
SET @LoopCount = (SELECT Count(*) FROM KC_PaymentTransactionIDConversion with (nolock) Where KC_Transaction_ID is NULL and TransactionYear is NOT NULL)
WHILE (
   SELECT Count(*)
   FROM KC_PaymentTransactionIDConversion with (nolock)
   Where KC_Transaction_ID is NULL
   and TransactionYear is NOT NULL
) > 0
BEGIN
   IF @LoopCount < 0
       RAISERROR ('Issue with data in KC_PaymentTransactionIDConversion, loop has run more times than expected (Loop Counter went negative).', -- Message text.
               16, -- Severity.
               1 -- State.
SET @LoopCount = @LoopCount - 1
end
I am getting error as "loop has run more times than expected (Loop Counter went negative)"
Could any one help on this issue ASAP.
Thanks ,
Vinay

Hi Vinay,
According to your code above, the error message make sense. Because once the value returned by “SELECT Count(*) FROM KC_PaymentTransactionIDConversion with (nolock) Where KC_Transaction_ID is NULL and TransactionYear is NOT NULL” is bigger than 0,
then decrease @LoopCount. Without changing the table data, the returned value always bigger than 0, always decrease @LoopCount until it's negative and raise the error.
To fix this issue with the current information, we should make the following modification:
Change the code
WHILE (
SELECT Count(*)
FROM KC_PaymentTransactionIDConversion with (nolock)
Where KC_Transaction_ID is NULL
and TransactionYear is NOT NULL
) > 0
To
WHILE @LoopCount > 0
Besides, since the current query is senseless, please modify the query based on your requirement.
If there are any other questions, please feel free to ask.
Thanks,

Errors executing SQL query in EJB 2.0 QL using RAD-6.0 on WAS-6.0

I have 3 tables in my database which is running on DB2 UDB ESE V-8.2
The tables are emp, dept & policy_master respectively
Table emp has columns id, name, deptid, and policyid.Here dept id and policyid are foreign keys which are referenced by dept and policy_master tables
In the dept table column deptid is primay key and non-key is dept name
In my policy_master table i have column policyid as primay key and non-key column is policy name
Now i want to find records in emp table by deptid column in emp table which should return a emp local interface
Now for that i had written ejbql "select object(o) from emp o where o.deptid=?1" using finder method namely findByDeptid(String deptid) in emp entity bean.
When i execute the entity bean using RAD Test Client,I am getting following 2 errors namely:
1. "WQRY0036E: Emp o does not have a field deptid in ejb-jar.xml "
2. "Class must implement the inherited abstract method CMPEmpLocalHome.findByDeptid(String) EJSLocalCMPEmpHome_0783c8c6.java TestEJB/ejbModule/sample"
When i analysed the problem i found that the deptid in emp bean is not defined as a CMP field in the map file & deployment descriptor that is why i am not able to write such kind of ejb queries.The deptid field in emp table is having a foreign key relationship with dept table.
Detailed Discription of tables structure

I used "select object(o) from emp where deptid=?1" then I am getting error in "ejb-jar.xml" that field does not exist.
So please tell me how can I find records in emp table so that the bean returns a local interface.

Try to connect without tnsnames. So try the basic connection from SQLDeveloper.
If it works, you have to verify your tnsnames.ora
Are you th only person to have this connection problem or all users meet this error?
Does this connection worked before, is it a new connection?
What changes occured since the connection is out of service.

SQL Query error in java swing Application

hi,
I'm getting the following error when i try to manipulate the date in query.I have set of tuples and would like to retrieve with respect to the date given.Please do help me to get rid of this error.This is the error.
MY QUERY:
ResultSet rsdate=st1.executeQuery("select * from phy_stock where date = "+d1+"");
Where d1 is given like this:
String startdate[2]="11/31/2008";
DateFormat df = new SimpleDateFormat ("MM/dd/yyyy"); //converting a string to DATE format.
Date d1 = df.parse(startdate[2]);
ERROR:
java.sql.SQLException: [Microsoft][ODBC Microsoft Access Driver] Syntax error (missing operator) in query expression 'date = Mon Sep 01 00:00:00 IST 2008'
thanks,
kumar.

Dates do not have formats. When referencing a Date in String concatenation, which is what you are doing here,
ResultSet rsdate=st1.executeQuery("select * from phy_stock where date = " + d1 + "");you will get what Date's toString method produces, which will not work for that (or any) query. For one, it wouldn't be surrounded by single quotes ('), and for two, the String format of the Date would not be acceptable by the DB (unless you had changed the DBs defaults).
Use a PreparedStatement, as suggessted above, and this problem goes away.
Edit: And make sure to use the setDate method, of course.

PL/SQL function body returning SQL query - ORA-06502: PL/SQL: numeric or value error

I'm attempting to dynamically generate a rather large SQL query via the "PL/SQL function body returning SQL query" report region option. The SQL query generated will possibly be over 32K. When I execute my page, I sometimes receive the "ORA-06502: PL/SQL: numeric or value error" which points to a larger than 32K query that was generated. I've seen other posts in the forum related to this dynamic SQL size limitation issue, but they are older (pre-2010) and point to the 32K limit of the DNS (EXECUTE IMMEDIATE) and DBMS_SQL. I found this post (dynamic sql enhancements in 11g) which discusses 11g no longer having the 32K size limitation for generating dynamic SQL. Our environment is on 11gR2 and using ApEx 4.2.1. I do not know which dynamic SQL method -- DNS or DBMS_SQL -- ApEx 4.2.1 is using. Can someone clarify for me which dynamic SQL method ApEx uses to implement the "PL/SQL function body returning SQL query" option?
As a test, I created a page on apex.oracle.com with a report region with the following source:
declare
l_stub varchar2(25) := 'select * from sys.dual ';
l_sql clob := l_stub || 'union all ';
br     number(3) := 33;
begin
while length ( l_sql ) < 34000 loop
    l_sql := l_sql || l_stub || 'union all ';
end loop;
l_sql := l_sql || l_stub;
for i in 1 .. ceil ( length ( l_sql ) / br ) loop
    dbms_output.put_line ( dbms_lob.substr ( l_sql, br, ( ( i - 1 ) * br ) + 1 ) );
end loop;
return l_sql;

The dbms_output section is there to be able to run this code in SQL*Plus and confirm the size of the SQL is indeed larger than 32K. When running this in SQL*Plus, the procedure is successful and produces a proper SQL statement which can be executed. When I put this into the report region on apex.oracle.com, I get the ORA-06502 error.
I can certainly implement a work-around for my issue by creating a 'Before Header' process on the page which populates an ApEx collection with the data I am returning and then the report can simply select from the collection, but according to documentation, the above 32K limitation should be resolved in 11g. Thoughts?

What setting do you use in your report properties - especially in Type and in Region Source?
If you have Type="SQL Query", then you should have a SELECT statement in the Region Source. Something like: SELECT .... FROM ... WHERE
According to the ERR-1101 error message, you have probably set Type to "SQL Query (PL/SQL function body returning SQL query)". In this situation APEX expects you to write a body of a PL/SQL function, that will generate the text of a SQL query that APEX should run. So it can be something like:
declare
mycond varchar2(4000);
begin
if :P1_REPORT_SEARCH is not null THEN
mycond:='WHERE LAST_NAME like :P1_REPORT_SEARCH ||''%''';
end if;
return 'select EMPLOYEE_ID, FIRST_NAME, LAST_NAME from EMPLOYEES ' ||mycond;
end;
And for escaping - are you interested in escaping the LIKE wildcards, or the quotes?
For escaping the wildcards in LIKE function so that when the user enters % you will find a record with % and not all functions, look into the SQL Reference:
http://download-uk.oracle.com/docs/cd/B19306_01/server.102/b14200/conditions007.htm
(You would than need to change the code of your function accordingly).
If you are interested in escaping the quotes, try to avoid concatenating the values entered by the user into the SQL. If you can, use bind variables instead - as I have in my example above. If you start concatenating the values into the text of SQL, you are open to SQLInjection - user can enter anything, even things that will break your SQL. If you really need to allow users to choose the operator, I would probably give them a separate combo for operators and a textfield for values, than you could check if the operator is one of the allowed ones and create the condition accordingly - and than still use bind variable for inserting the filtering value into the query.

Error in report when executing pl/sql function body returning sql query.

Hi,
I have used the pl/sql function body returning sql query for creating a report. I have created a datepicker(
P10_TASK_DATE) which can be submitted.The code is as below
DECLARE
v_sql varchar2(3000);
BEGIN
if :P10_TASK_DATE is not null THEN
v_sql:='select
* from tasks';
return v_sql;
else
v_sql:='select * from discovery';
return v_sql;
END IF;
END;if the date field is empty "select * from discovery" is executed and report is getting generated. But when we give a
date using date picker the page is submitted and i get "report error: ORA-01403: no data found" even
though the "tasks" table has data in it. Plz help
Thanks,
TJ

hi
Please try this
1. Create 2 region
1st region source=
select * from tasks'
go to the tab -> condition =
item NOT NULL
EXpression1 =:P10_TASK_DATE
this will run whenever the item have any date
2. open your 2 nd region source code= select * from discovery
put the condition
item is NULL
EXpression1 =:P10_TASK_DATE
thanks

Getting zero-sized reply error when running report from SQL query

Hi,
I have a Report from SQL Query in Portal. When I select Excel in Output Format and then run the report, it works properly, but when I select HTML in Output Format, the report works if the rows returned are not so many (I've been able to display the report for up to 701 rows), but when I try selecting a value from the LOV that selects many rows, I get the following error:
ERROR
The requested URL could not be retrieved
While trying to retrieve the URL: <data suppressed>
The following error was encountered:
Zero Sized Reply
Squid did not receive any data for this request.
Any ideas on how to fix this? Why does the number of rows returned affect the report this way?
Thanks,
Lorena

Problem comes when any of the filter is applied in any one of the cases selected from the GUI.Do you mean that the problems only shows when you run the report in your browser via 9iAS?
Which version are you using?
Can you post the before report trigger?
