I have a problem in my ejb java application .. and trying to solve it I stumble on this issue.
in my ejb class, I have a finder method
/* #ejb.finder signature="java.util.Collection findByAllMultiPlan(<list
of arguments>)"
*
* query="SELECT OBJECT(e)
* FROM ElementTbl as e
* WHERE <LOTS OF STUFF>"
That method fails sometimes, not all the time. (most of time when ran in a loop over a large data inputs) It can fail on a 8th, 10th or 35th iteration, etc..
It fails with the "Finder" exception
javax.ejb.EJBException: nested exception is: javax.ejb.FinderException:
Exception in findByCriteria while preparing or executing query:
statement: 'weblogic.jdbc.wrapper.PreparedStatement_com_inet_tds_r#bd44a1'
java.sql.SQLException: The transaction is no longer active - status:
'Rolling Back. [Reason=weblogic.transaction.internal.TimedOutException:
Transaction timed out after 33 seconds
BEA1-655E9CABEFC3D5D9F078]'. No further JDBC access is allowed within this
transaction.java.sql.SQLException: The transaction is no longer active -
status: 'Rolling Back.
[Reason=weblogic.transaction.internal.TimedOutException: Transaction timed
out after 33 seconds BEA1-655E9CABEFC3D5D9F078]'. No further JDBC access is
allowed within this transaction.
In a log files, I see query executed in weblogic jpql format
SELECT WL0.mreUidID, WL0.mreDtmCreated, WL0.mreCdeCustType, WL0.mreIn...
.. many,many fields ...
FROM tblElement WL0 WHERE ( ( ( ( ( ( ( ( ( WL0.elVchID= ? ) AND (
((((((((WL0.elVchAnotherId = ? ) .. and a lot of fields encoded with
"WL0.field =?"
There is NO output of values that are set in place of ?
So, question is: Is it possible to translate that JPQL language into plain SQL so to run in query analyzer?
Again, query is very large to be parsing it every time I need to test a particular scenario... it will take me close to more than an hour to fill in everything..
There must be a java method or utility to get access to this from within my EJB class.
Please help !!!

I've got a Hive SQL script/action as part of an Oozie workflow. I'm doing a CREATE TABLE AS SELECT to output the results. I want to name the table using the username plus an appended string (e.g. "User123456_output_table"), but can't seem to get the correct syntax.
set tablename=${hivevar:current_user()};
CREATE TABLE `${hiveconf:tablename}_output_table` AS SELECT ...
That doesn't work and gives:
Error while compiling statement: FAILED: IllegalArgumentException java.net.URISyntaxException: Relative path in absolute URI: ${hivevar:current_user()%7D_output_table
Or changing the first line to set tablename=${current_user()}; starts running the SELECT query but eventually stops with:
Error while processing statement: FAILED: Execution Error, return code 1 from org.apache.hadoop.hive.ql.exec.DDLTask. org.apache.hadoop.hive.ql.metadata.HiveException: [${current_user()}_output_table]: is not a valid table name
Or changing the first line to set tablename=current_user(); starts running the SELECT query but eventually stops with:
Error while processing statement: FAILED: Execution Error, return code 1 from org.apache.hadoop.hive.ql.exec.DDLTask. org.apache.hadoop.hive.ql.metadata.HiveException: [current_user()_output_table]: is not a valid table name
Alternatively, is there a way to pass the username from the Oozie workflow via a parameter?
I'm using Hue to do all this rather than the command line.
Thanks
This is wrong: set tablename=${hivevar:current_user()}; - it will not be resolved and substituted as is.
Hive does not calculate variables before substitution, it substitutes them as is, all functions in variables are NOT calculated. variables are just text replacement.
This:
set tablename=current_user();
CREATE TABLE `${hiveconf:tablename}_output_table` ...
gets resolved as
CREATE TABLE `current_user()_output_table` ...
And functions are not supported in table names, it will not work this way.
The solution is to calculate functions outside the script and pass them as parameters.

I got a query working from long ago, the query is build by JPA, but today threw an exception:
org.springframework.web.util.NestedServletException: Request processing failed; nested exception is org.springframework.orm.hibernate3.HibernateJdbcException: JDBC exception on Hibernate data access: SQLException for SQL [n/a]; SQL state [99999]; error code [29902]; could not extract ResultSet; nested exception is org.hibernate.exception.GenericJDBCException: could not extract ResultSet at org.springframework.web.servlet.FrameworkServlet.processRequest(FrameworkServlet.java:973)
Long story short, it gives SQL state [99999]; error code [29902]; a parameter problem.
The query its build like this:
select * from mytable where CONTAINS(field1, 'BT');
A little google-fu show me that BT its a query operator for Contains. This error can be reproduced searching by NOT, DIFMERGE, ABOUT, AND..
The question is, there is a way to escape the text so i can search by the word BT or his friends?
EDIT: i build the contains like this:
return builder.greaterThan(
builder.function("CONTAINS", Integer.class, exp, builder.literal(((String) param.getValue()).toUpperCase())),
0);
EDIT: I tried converting the text BT to unicode, but doesn't work either.
select * from myTableWHERE CONTAINS(field1, UNISTR('\0042\0054')) > 0
I am running a very simple query and trying to extract the results to a text file. The entire query is essentially what is below, I am selecting everything from one single table with one piece of where criteria which is limiting the data to one month's worth. After it has extracted around 1.2 gig this error shows up. Is there any way that I can work around this other than extracting smaller date ranges? I am trying to pull a couple of years worth of data so if I can only get it a few days at a time it will take a lot of manual work.
I am currently using the free trial of a DB2 query tool - Razor SQL if that makes a difference, I can probably purchase different software if it would help. I am trying to get IBM's tool but for some reason it freezes during the download so I am still working on that. I have searched about this error but everything I see seems much more complex than what I am doing and I can't tell if it applies or not. Thanks in advance.
select *
from MyTable
where date_col between date '2014-01-01' and date '2014-01-31'
I stumbled at this error too, found out it is related to db2jcc.jar (type 4) driver.
Excerpt: If there are no items in the result set left (or to begin with), the Result set is closed automatically and therefore the Exception. Suggestion is to handle it in the application, perhaps in my case, I started checking if(rs.next()) but otherwise, there is a work around. Check out the source link below for how you can set some properties to Data source and avoid exception.

"Invalid operation: result set is closed" error with Data Server Driver for JDBC
In my case, i missed some properties in WAS, after add allowNextOnExhaustedResultSet the issue is fixed.
1.Log in to the WebSphere Application Server administration console.
2.Select Resources > JDBC > Data sources > Application Center DataSource name > Custom properties and click New.
3.In the Name field, enter allowNextOnExhaustedResultSet.
4.In the Value field, type 1.
5.Change the type to java.lang.Integer.
6.Click OK.
Sometimes you need also check whether resultSetHoldability properties exists. Details refer to here.
I encountered this failure also when ugrading from JDBC Type 2 driver (db2java.zip) JDBC type 4 driver (db2jcc4.jar)
Statement statement = results.getStatement();
if (statement != null)
{
connection = statement.getConnection(); // ** failed here
statement.close();
}
Solution was to check if the statement is closed or not as follows.
Changed to:
Statement statement = results.getStatement();
if (statement != null && !statement.isClosed()) {
{
connection = statement.getConnection();
statement.close();
}
Creating property bellow with type Integer it's worked for me:
allowNextOnExhaustedResultSet:
I had the same issue on WAS 7 so i had to add and change few this on Admin Console.
This TeamWorksRuntimeException exception should be fixed by applying APAR JR50863 which is available on top of BPM V8.5.5 or included on BPM V8.5 refresh pack 6.
For the case that the APAR does not solve the problem, try following workaround:
Log in to the WebSphere Application Server admin console
Select Resources > JDBC > Data sources > DataSource name (TeamWorksDB) > Custom properties and click New
In the Name field, enter downgradeHoldCursorsUnderXa
In the Value field, type true
Change the type to java.lang.Boolean
Click OK to save your changes
Select custom property resultSetHoldability
In the Value field, type 1
Click OK to save your changes

Restarting the app may fix the problem if connection pool lost session to Db2. If using Tomcat then connection pool property of 'testonBorrow' may reestablish the connection to Db2.
I am getting this error and don't understand why:
Error Executing Database Query. [Macromedia][SQLServer JDBC
Driver][SQLServer]Invalid column name 'buildno'. The error occurred
in C:/data/wwwroot/webappsdev/cfeis/redbook/redbook_bio_load.cfm: line

8 : select *

11 : </cfquery>
12 :
VENDORERRORCODE: 207 SQLSTATE: 42S22 SQL: select * from
redbook_bio where buildno = '4700' DATASOURCE: xxxx
******"
It is saying buildno is an invalid column name, but I do not have that name in my query. I used to, but changed both the column in the database and the column name in the query to build_num. You can see my exact code with line numbers, and that there is no 'buildno' in there. But looking at the SQL statement below that, it is still trying to use 'buildno'.
I had my editor check the directory for anywhere it says buildno and no results came back. I have restarted the CF Service and cleared the cache. Why would it still be trying to run it with buildno instead of build_num like the code says?
There was a cfquery cache setting in the Administrator. We had it set to 100. Apparently clearing the cache template and component cache doesn't clear the cfquery cache. I changed the query name and it fixed the problem. It most likely could have been fixed by setting the cfquery cache value to 0.
I have a bug I've been trying to track down for a few weeks now, and have pretty much isolated exactly what's going wrong. However, why this happens is beyond me.
I have a very large Oracle package (around 4,100 lines of code) and I'm calling several procedures. However, data seems to be getting lost between procedure calls.
The data that is being lost is:
dpmethodstate varchar_state_local_type;
First, I call this procedure:
PROCEDURE delivery_plan_set_state (
messages OUT ReferenceCursor,
state IN varchar_state_local_type
) AS
BEGIN
logMessage('state COUNT is: ' || state.COUNT);
dpmethodstate := state;
FOR I IN 1..dpmethodstate.COUNT LOOP
logMessage(dpmethodstate(I));
END LOOP;
logMessage('delivery_plan_set_state end - dpmethodstate count is now ' || dpmethodstate.COUNT);
OPEN messages FOR SELECT * FROM TABLE(messageQueue);
messageQueue := NULL;
END delivery_plan_set_state;
I pass in state, which is a valid array of a single string. I can verify in the logs that dpmethodstate has a COUNT of 1 when the procedure ends.
Next, I call the execute_filter procedure which looks like this:
PROCEDURE execute_filter (
--Whole bunch of OUT parameters
) AS
--About 50 different local variables being set here
BEGIN
SELECT TO_CHAR(SYSTIMESTAMP, 'HH24:MI:SS.ff') INTO TIMING FROM DUAL;
logMessage('[' || TIMING || '] execute_filter begin');
logMessage('a) dpmethodstate Count is: ' || dpmethodstate.COUNT);
--Rest of procedure
However, this time dpmethodstate.COUNT is 0. The value I set from delivery_plan_set_state has vanished!
When I look at my logs, it looks something like this:
proposed
delivery_plan_set_state end - dpmethodstate count is now 1
[21:39:48.719017] execute_filter begin
a) dpmethodstate Count is: 0
As you can see, dpmethodstate got lost between procedure calls. There's a few things to note:
Nothing else in this package is capable of setting the value for dpmethodstate besides delivery_plan_set_state. And I can see nothing else has called it.
My client side code is written in C#, and not much happens between the two procedure calls.
This happens perhaps 1 out of every 100 times, so it's very difficult to track down or debug.
First off, what's the best way to debug a problem like this? Is there any more logging I can do? Also, how does Oracle maintain state between procedure calls and is there anything that can intermittently reset this state? Any pointers would be much appreciated!
Is dpmethodstate a package global variable? I'm assuming it is, but I don't see that explicitly mentioned.
Since package global variables have session scope, are you certain that the two procedure calls are always using the same physical database connection and that nothing is using this connection in the interim? If you're using some sort of connection pool where you get a connection from the pool before each call and return the connection to the pool after the first call, it wouldn't be terribly unusual in a development environment (or low usage environment) to get the same connection 99% of the time for the second call but get a different session 1% of the time.
Can you log the SID and SERIAL# of the session where you are setting the value and where you are retrieving the value?
SELECT sid, serial#
FROM v$session
WHERE sid = sys_context( 'USERENV', 'SID' );
If those are different, you wouldn't expect the value to persist.
Beyond that, there are other ways to clear session state but they require someone to take explicit action. Calling DBMS_SESSION.RESET_PACKAGE or DBMS_SESSION.MODIFY_PACKAGE_STATE(DBMS_SESSION.REINITIALIZE) will clear out any session state set in your session. Compiling the package will do the same thing but that should throw an error warning you that your session state was discarded when you try to read it.
