SQL query throwing Exception.
Hi,
i am facing a problem while using the date as search criteria. In the JDO class the field type is of java.util.Date. The search is working in the local environment whose local date settings as M/d/YYYY(windows 2003 , english version).The search is not working in the chines OS environment , where the local date setting is YYYY-M-d. In the chinese enviroment , if we alter the session NLS settings in toad, we could able to execute the query.
we are using kodo-2.5.8
SELECT t0.JDO_ID, t0.JDO_CLASS, t0.BAD_NAMES, t0.CONCAT_NAME, t0.DDATE, t0.FIRST_NAME, t0.LAST_NAME, t0.MAX_SCN, t0.NAME,
t0.NATURALID, t0.PARTYID, t0.PHONE, t0.ROLE FROM PARTY_VBO t0 WHERE (t0.ROLE LIKE '%ICR%' AND t0.DDATE = '17-APR-1974' AND ROWNUM <= 25) AND
t0.JDO_CLASS = 2 ORDER BY t0.PARTYID ASC)
This Query is throwing ORA-01843.
From where the session opened by the java in oracle will take the data format?
Plaese help.
One of my sql query is throwing exception during
execution. I do not know which one (there are several
of them). Is there a way to display or extract the
last query from SQLException class.
Any help will be highly appreciated.
Thanks,
Indrasish.No there is not. You should do some debugging, such as logging something like: "Executing query: SELECT blahblahblah" - then execute the query, then log something like: "Query completed". Then find in your log which one didn't complete.

SQL Query and Exception ORA-01722
Hi,
I have a table called t_lookup which has three columns Lookup_Value, Description and Lookup_Type all of them are varchar2 type. If I execute the below query, its working fine
SELECT *
FROM (SELECT Lookup_Value
*,To_Number(Description) Dd*
FROM t_Lookup
WHERE Lookup_Type = 'CALENDAR') Tab ;
Here is the result
Lookup_Value .............. Dd
January....................... 1
February..................... 2
March......................... 3
April........................... 4
May........................... 5
June.......................... 6
July........................... 7
August....................... 8
September................... 9
October...................... 10
November................... 11
December................... 12
But when i execute
SELECT *
FROM (SELECT Lookup_Value
*,To_Number(Description) Dd*
FROM t_Lookup
WHERE Lookup_Type = 'CALENDAR') Tab
AND Dd = 9;
then it is throwing ORA exception
ORA-01722: invalid number
Can any one help me on this in order to understand the root cause of this problem? Oracle server I am using is "Oracle9i Release 9.2.0.8.0" .
ThanksI'm assuming that it is intended that certain descriptions will have non-numeric data in them, right?
Assuming that is the case, the success or failure of the query will depend on how the optimizer happens to choose to execute your query. If it happens to run the TO_NUMBER function before it filters out a row with non-numeric data, you'll get an error. If it happens to run the TO_NUMBER after filtering out all the rows with non-numeric data, the query will be successful. Given that query plans are subject to change, particularly when you eventually upgrade, you probably don't want to just find a SQL query that works, you'll need to ensure that either the query plan never changes or that the query is formulated in such a way that it will never fail.
My first thought would be whether you really need to store numeric data in a VARCHAR2 field in the first place. I'm guessing this is some sort of generic lookup table (which cause a raft of issues, this being one). Can you at least store string, date, and number data in separate columns?
Barring that, can you create your own PL/SQL function that converts a string to a number and catches the exception?
CREATE OR REPLACE FUNCTION my_to_number( p_arg IN varchar2 )
RETURN NUMBER
IS
l_num NUMBER;
BEGIN
l_num := to_number( p_arg );
RETURN l_num;
EXCEPTION
WHEN others THEN
RETURN NULL;
END;That will ensure that the query will be successful regardless of the plan. Note that you would probably want to catch just the ORA-01722 error, not OTHERS, in your real code-- this is just a sample.
Barring that, you'll need to do something to enforce stability in the query plan. A stored outline that forces this query to use the query plan that doesn't generate an error.

Second call of an SQL query throws a syntax error?
Private Sub RefreshDataSet()
Dim strSQL As String = DataAdapter1.SelectCommand.CommandText
Try
DataSet1.Clear()
DataAdapter1.SelectCommand.CommandText() = Trim(strSQL & " WHERE BadgeID = " & strEmployeeBadge)
DataAdapter1.Fill(DataSet1)
Catch ex As Exception
MsgBox(ex.Message)
End Try
End Sub
When I call the above procedure, the sub does work correctly and I get the expected results / records in the dataset. But, when I call the Sub again (to refresh the dataset) it gives me an "incorrect syntax" error.
I'm not sure why it is doing this. Any suggestions or ideas?Youjun,
It's very frustrating when you keep asking if the code is the same, or if I have tested the code. I've said that I debugged.. I've said I have tested the code. Your continuing to ask me this is pointless, rude, and only serves to make YOU look
stupid. I'm sorry if that is rude, but please stop asking me!
To respond:
I supposed that the original DataAdapter1.SelectCommand.CommandText is "select * from table1"
-Yes, the base command is similar to this, except that I call each database field, not using the *.
1) When you run it the first time, the DataAdapter1.SelectCommand.CommandText will be "select * from table1 WHERE BadgeID ='123'".
-Yes, I append 'WHERE BadgeID = XXX' to the query, the first and
each subsequent time. Again, I said that the code/call/syntax DOES NOT CHANGE. It is the
same every time.
2) Then you changed the strEmployeeBadge, I supposed that is '234'
-NO! I do NOT change the code!! I'm sorry, but what part of 'the query is
exactly the same' is unclear?
3) when you run it next time, the DataAdapter1.SelectCommand.CommandText will change to "select * from table1 WHERE BadgeID ='123'
WHERE BadgeID = '234'"
-NO! I have specifically tested for this
and as stated, the SQL syntax does not change!
So it 'syntax' fail will pop out when second call.
-NO, your assumptions are INCORRECT.
I suggest you recording the commandText when first change the DataAdapter1.
I write a testing program for you.
-Your 'testing program' is for all purposes, the same exact code as what I used. There is no difference.
Now, as also stated before, I have several other instances
where I use the same 'technique' to amend the base SQL queries of the DataAdapter. Each of these other instances work fine, and I use them to 'refresh' my DataSet information several times throughout the running of my program. Just for some
reason, this time, it does not work. I don't know why and was hoping someone else had found the same/similar issue and also found a resolution. The DataAdapter is configured the same as the others, the code is the same as well. I will just
have to find a work around, or other way to do what I want I guess.
Lastly, yes, I set strSQL in the subroutine because I want that variable to be gone at the end of the procedure. It recalls, then sets the syntax, every time the Sub is called on purpose. I do not want strSQL to be 'global', which by the way,
according to Microsoft documentation I have read, is no longer possible. Global variables are 'technically' not used/recognized anymore. If this has changed, then I stand corrected.
Thank you for responding, I will just find another solution I guess. -
SQL query throws not understandable error
Hi everybody,
I am suffering from an issue where I query Oracle database 11g with this query:
SELECT AUDIT_EVENT.EVENT_ID, USER_NAME, START_TIMESTAMP, AUDIT_EVENT.DURATION, AUDIT_EVENT.EVENT_TYPE_ID, AUDIT_EVENT.SERVER_CUID, OBJECT_CUID, OBJECT_TYPE, ERROR_CODE, OBJECT_ID, DETAIL_ID, AUDIT_DETAIL.SERVER_CUID, AUDIT_DETAIL.DETAIL_TYPE_ID, DETAIL_TYPE_DESCRIPTION, EVENT_TYPE.EVENT_TYPE_DESCRIPTION, SUBSTR(DETAIL_TEXT,0,200) as DETAIL_TEXT FROM (audit_detail join detail_type on audit_detail.detail_type_id=detail_type.detail_type_id) join (audit_event join event_type on audit_event.event_type_id=event_type.event_type_id) on audit_event.event_id=audit_detail.event_id WHERE to_char(START_TIMESTAMP,'YYYYMMDD') > '20110307' AND to_char(START_TIMESTAMP,'YYYYMMDD')<='20110309' ORDER BY START_TIMESTAMP
which throws this error:
ORA-01652: unable to extend temp segment by 128 in tablespace TEMP
01652. 00000 - "unable to extend temp segment by %s in tablespace %s"
*Cause: Failed to allocate an extent of the required number of blocks for
a temporary segment in the tablespace indicated.
*Action: Use ALTER TABLESPACE ADD DATAFILE statement to add one or more
files to the tablespace indicated.
Can anybody explain why this can happen? Are we somehow limited with temporary space or whatever? Because when I put the same query withou condition placed after WHERE clause it seems to work correctly...
Appreciate any help..
Thank You
MiroTemp space can be used for SORTS and HASH joins, for example.
See documentation for further details:

Please review the execution plans for both queries that you mention.
e.g.
explain plan for...
select * from table(dbms_xplan.display);The output of dbms_xplan should display expected/estimated temp space usage.
Please see the following thread for more detail:
How to post a SQL tuning request - HOW TO: Post a SQL statement tuning request - template posting
I see that you using a TO_CHAR on your START_TIMESTAMP column.
This is a classic way of preventing index usage which may lead to inefficient plans which might cause unexpected temp space usage.
See execution plans for further detail.
If START_TIMESTAMP is indexed, then doing the following may result in a more efficient plan which might lead to reduced temp space usage, any sort operation ing might even be eliminated:
WHERE START_TIMESTAMP >= TO_DATE('20110307','YYYYMMDD')
AND START_TIMESTAMP < TO_DATE('20110309' ,'YYYYMMDD') + 1 -

Hi All,
I am reading notepads files and inserting data in sql tables from the notepad-
while performing sql bulk copy on this line it throws exception - "bulkcopy.WriteToServer(dt); -"data type related(mentioned in subject )".
Please go through my logic and tell me what to change to avoid this error -
public void Main()

string[] filePaths = Directory.GetFiles(@"C:\Users\jainruc\Desktop\Sudhanshu\master_db\Archive\test\content_insert\");
for (int k = 0; k < filePaths.Length; k++)
string[] lines = System.IO.File.ReadAllLines(filePaths[k]);
//table name needs to extract after = sign
string[] pathArr = filePaths[0].Split('\\');
string tablename = pathArr[9].Split('.')[0];
DataTable dt = new DataTable(tablename);

conn.Open();
SqlBulkCopy bulkcopy = new SqlBulkCopy(conn);
bulkcopy.DestinationTableName = dt.TableName;
bulkcopy.WriteToServer(dt);
conn.Close();
Issue 1:-
I am reading notepad: getting all column and values in my data table now while inserting for date and time or integer field i need to do explicit conversion how to write for specific column before bulkcopy.WriteToServer(dt);
Issue 2:- Notepad does not contains all columns nor in specific sequence in that case i can add few column ehich i am doing now but the issue is now data table will add my columns + notepad columns and while inserting how to assign in perticular colums?
sudhanshu sharma Do good and cast it into river :)Hi,
I think you'll have to do an explicit column mapping if they are not in exact sequence in both source and destination.
Have a look at this link:
https://msdn.microsoft.com/en-us/library/system.data.sqlclient.sqlbulkcopycolumnmapping(v=vs.110).aspx
Good Luck!

Regarding Exceptions of a SQL query
Hi,
We have a problem regarding the sql query shown below:
select max(column1) into var1
from table1
where column2 = 100;
We don't have any rows in the table1 but we are not getting the "NO data exception" while executing the query in a procedure.
If we modify the query to
select column1 into var1
from table1
where column2 = 100;
then 'No data found' exception is raised.
Can you please let us the reason behind this.
Thanks in advance.
LakshmiCut from Oracle documentation
If a query with an aggregate function returns no rows or only rows with nulls for the argument to the aggregate function, the aggregate function returns null.
AVG
COUNT
GROUPING
MAX
MIN
STDDEV
Aggregate function don't return 'No datafound Exception" I believe....Correcte me if i am Worng

How to retrieve a SQL query (in String format) from a PreparedStatement
Hello all,
I am in the process of unit testing an application accessing a Oracle 9i 9.2 RDBMS server with JDBC.
My query is:
As I have access to PreparedStatement and CallableStatement Java objets but not to the source queries which help create those objects?
Is thtere a simple way by using an API, to retrieve the SQL command (with possible ? as placeholders for parameters).
I have already looked at the API documentation for those two objets (and for the Statement and ResultSetmetaData objects too) but to no avail.
Thank you for any help on this issue,

Final word:
The final word about this is: there is currently three ways to obtain source SQL queries from compiled statement objects.
a) Use a proxy class the mConnector above;
b) Use a proxy JDBC driver as Log4JDBC;
c) Use the trace facility of the driver (however, post analyzing the logs would depend upon the driver selected).

OutOfMemory error while executing sql query
Hello!
My program gets multiple datas from database in every ten minutes, and stores them in memory for hundreds of users, requesting datas via web-interface simoultaneously.
I dont have access to change database structures, write stored procedures, etc, just read from db.
There is a table in database with lot of million rows, and sometimes when I try to execute a SELECT on this table it takes minutes to get back the result.
To avoid waiting for database server for a long time, I set querytimeout to 30 seconds.
If the server throws back the execution with Query Timed out Exception, I want to 'forget' this data, and 0 value is acceptable because of fast run is more important. So I put the boolean broken variable to check if there is any problem with db server.
The size of the used memory is about 150Mb if things going well, but I set the max heap to 512 MB, just in case anything happens.
I'm logging all threads stacktrace, and free/used/allocated memory size in every 5 seconds.(threadwatching.log) 2.appendix
Sometimes, not in every case (I dont know what is this depends on), when I get the next phase of refreshing cached datas (you can see it below), the process reaches the fiorst checkpoint (signed in code below), starts to execute the sql query, and never reaches the second checkpoint , but used memory growing 50-60 Mb-os in every 5 seconds, as I can see in threadwatching.log until it reaches the max memory and throws OutOfMemory error: java heap space.
I'm using DbConnectionBroker for connection pooling, SQLCommandBean for handling Statements, PreparedStatements, etc, and jTDS jdbc connector.
SQLCommandBean closes statements, resultsets, so these objects doesnt stays open.
I cant figured out what causes the memory leak, if someone have an idea, please help me.

I would appreciate for any help.What does your query bring back from this table?This is the query:
SELECT case sum(c.picked) when 0 then 0 else
((sum(c.picked)-(sum(c.picked)-(sum(c.vacuum)+sum(c.id
ent))))*cast((1000000/cast(sum(c.picked) as float))
as bigint)) end as PPM
FROM sip_comp c
LEFT JOIN sip_pcb pc ON pc.id=c.pcbid
LEFT JOIN sip_period p on p.id=pc.periodid
WHERE p.stationid=? AND pc.time BETWEEN ? AND ?Has anybody who knows SQL tried EXPLAIN PLAN to optimize this table? You're joining on a table with a million rows and you're wondering why the performance is poor?
What is the index situation with these tables?
.> When I execute it from query manager, it takes from 1
to 60 secs depend on servers availability. So how will that be any different for JDBC and Java?
..> You're right. Thats why I am here.
What I mean by that is we can't read minds, either. You need to get some hard data to tell you where the bottleneck is. Asking at a forum won't help.
But tell me, if the java process enters to this query
execution, and doesnt quit until OOM thrown, how can
be the problem in caching?I was guessing about caching, because I didn't know what the query was.
You expect a lot.
.> No.
Then how do you ever expect to solve this?
I tried YourKit Profiler at home, where I'm
developing software, but this OOM never thrown here,
even if I have the same database size.Then you aren't replicating the problem. You have to run it on the system that has the problem if you're going to solve it.
YourKit isn't an industry leader. How well do you know how to use it?
It just happened at the company where the system
runs, and I cannot run this profiler there because
the PC where my tomcat runs dramatically slowed.You have to run something to figure out what the problem is. What about Log4J, some trace logging statements and a batch job to harvest the log?
Bottom line: you've got to be a scientist and get some real data. We can theorize all we want here, but that won't get you to a solution.

Oaf: putting validation in VO based on sql query
Hi All,
I need few inputs for the customization of OAF page.
Business Need: Restriction of special character in supplier oaf pages for supplier name.
There are 3 oaf pages involved in supplier creation/update for R 12.1.3
1) oracle\apps\pos\supplier\webui\OrganizationPG (underlying VO is sql query based).
2) oracle\apps\pos\supplier\webui\QuickUpdatePG (underlying VO is sql query based).
3) oracle\apps\pos\supplier\webui\SuppCrtPG (underlying VO is based on EO - HzPuiOrgProfileQuickEOEx) .
For pages referring EO, we have extended the underlying EO and override the validateEntity() method to throw the OAAttrValException. After substitution, validation is working.
For VO based on query, the standard AM’s are instantiating the VO and using Rowimpl class they are setting the attributes.
Question: How to enforce validation logic in VO or AM in such cases where oracle standard code is instantiating the VO dynamically?
One possible solution is to use the PPR event on input text message bean and catch it in custom controller’s processFormRequest method and before super. processFormRequest(), we can put the validation.
Is there any other way to achieve it?VO extension will not work as the
Standard Controller code : oracle.apps.pos.supplier.webui.QuickUpdateCO is calling the AM's method on the click of save button and AM is dynamically invoking the methods in VO.
Standard Controller code:
OAApplicationModule oaapplicationmodule = oapagecontext.getApplicationModule(oawebbean);
if(oapagecontext.getParameter("btnSave") != null)
oaapplicationmodule.invokeMethod("updateVendor");
oaapplicationmodule.invokeMethod("updateVendorSites");
oaapplicationmodule.getTransaction().commit();
Corressponding standard standard AM code...

Hi all,
I have data in the following manner:
CASE_NUMBER HOURS FLAG
1000 10 0
1000 20 0
1000 30 1
1000 40 0
1000 50 1
Here I need to Calculate the total hours for a Case_number till i see the flag as 1.
Here the result must be 10+20+30 Hrs
Another Example
CASE_NUMBER HOURS FLAG
2000 10 1
2000 20 1
Here the result must be only 10.
I am struggling to write a SQL query for this.
Anyones help will be very much greatful
Thanks in Advance
Regards,
Sengathir SubbarayanLook up analytical functions.
something like sum(hours) OVER (PARTITION BY case_number ORDER BY something)
will give you the sum for all rows.
Then you probably want to "throw away" those rows after the flag maybe by summing the flag column too, and throw away all those where the flag is greater than 1 and where it is equal to 1 except for the first one.
I suspect you actually have some other column (other than the number of hours) that define your order - that's what you put in the ORDER BY.

Creating a dynamic SQL query builder class
I have a jobs table where each row contains information about jobs run on a machine. I have a web view of this database which shows different information and queries for this information are built using the following fields:
TYPE
TITLE
NODE
STATUS (an array of 4 different possible statuses)
TIMESTAMP
GUID (will be used when a view of a specific job (row in the table) is requested, no other search criteria needed when this view is required.)
All the criteria will be passed from the view layer into a search criteria object which is then passed to the DAO class which passes it to a BuildSQL class to use it to build the SQL.
There are many different "views" of the data which will result in many different combinations of criteria being passed down to the data access layer. (for example a status of failed and a timestamp resulting in all the jobs run in the last 2 hours)
As there are a number of different search criteria used in each query I'm having trouble designing the class to dynamically build the query. Are there any standard ways of doing this out there that could guide me?
At the moment I'm seeing this class as being a large combination of if statements and not really being very dynamic.
I was thinking maybe checking all the criteria to see if its null, if so ignore it straight away and then running through all the other criteria and appending one by one to the may SELECT which has already been created. Quite how i'd decided whether it would need an AND or OR before it I dont know.
Are there any standard proven ways to approach this because i've done a search here and on google and not really come back with much, so any advice would be great. I've got to say I'm pretty new to java and don't really have many bright ideas here!Well my dear friend... I did something special for a business logic support to an web autocomplete component.
The criteria building was based on a custom variable into the SQL statement:
SELECT * FROM TABLE WHERE __MC__ AND (FIXED CRITERIA)
Where:
*FIXED CRITERIA: Is a fixed criteria that doesn't variate
*__MC__: Is a "custom variable" defined for me to make the replacement.
There are two main clases:
*SQLBuilder: It has many logic to build SQL Statements
*Multicriteria: It has the specific logic to insert into a SQL statement multiple criterias
// The SQLBuilder class
public class SQLBuilder {
public static final String MC = "__MC__";
static String buildMultiCriteria(String sql, Object[] params) throws Exception {
for(int i=0; i<params.length; i++) {
if(params[i] instanceof MultiCriteria) {
sql = sql.replaceFirst("__MC__",
((MultiCriteria)params).getCriteria());
params[i] = null;
return sql;
// The MultiCriteria class
public class MultiCriteria {
public static final int BEGINS = 0;
public static final int ENDS = 1;
public static final int CONTAINS = 2;
private String criteria = null;
public MultiCriteria(String[] fields, String value, int type) throws Exception {
String[] tokens = value.split(" ");
StringBuffer sb = new StringBuffer("(");
for(int i=0; i<fields.length; i++) {
for(int j=0; j<tokens.length; j++) {
if(tokens[j].length()>0) {
sb.append(fields[i].toUpperCase());
sb.append(" LIKE '");
sb.append(toType(tokens[j], type));
sb.append("'");
if(j<tokens.length-1) sb.append(" OR ");
if(i<fields.length-1) sb.append(" OR ");
sb.append(")");
criteria = sb.toString();
public String getCriteria() {
return criteria;
private final String toType(String value, int type) throws Exception {
switch(type) {
case BEGINS:
value = value + "%";
break;
case ENDS:
value = "%" + value;
break;
case CONTAINS:
value = "%" + value + "%";
break;
default:
throw new Exception("Undefined MutiCriteria type");
return value;
// I use the MultiCriteria this way
// criteria is a string introduced in a html input text
// The class splits the string by " " and ensemble multiple criterias
// for the given fields permuting them with the tokens resulting of the
// split
MultiCriteria mc = new MultiCriteria(
new String[] {"FIELD_01", "FIELD_02"},
criteria,
MultiCriteria.CONTAINS
I think this idea could help you.

Java.sql.SQLException: Io exception: End of TNS data channel
Hello folks,
Has amyone encountered this exception? If so, could you please shed some light for what might be going wrong?
Here is my confuguration:
400MB RAM
1.2GHTz processor
Win2K Pro
Oracle server 9.0.1
JDBC Thin driver (libs for 9.0.1)
Scenario:
My Java code uses Oracle Spatial to insert SDO_GEOMETRY objects into my DB model.
I have a config file where I store my connection properties, e.g.,
<DBConnection name="twatest">
<JDBCDriver>oracle.jdbc.driver.OracleDriver</JDBCDriver>
<URL>jdbc:oracle:thin:@saturn:1521:saturn</URL>
<Username>user1</Username>
<Password>twatest</Password>
</DBConnection>
We have 2 schemas defined: user1 and twatest.
The problem first occured when I switched from user1 to twatest. Consequent attempt to run the process as user user1 failed! The Java SQL statements do not use schemas (so they default, I suppose, to the default schema for that particular user, in our case being user1-->user1, twatest-->twatest).
The problem happens in the following Java class (search for "HERE" to see where exactly the problem occurs):
package com.vividsolutions.twatest;
import java.util.*;

import oracle.sql.*;

I tried to find information on this on the net, but seems that this problem only happened when people dealt with LOBs?!
Thank you very much!
GeorgiSuresh -- I'd probably log a TAR with Oracle support for this question if you definitely need it resolved. Support have access to all manner of existing cases, so this may be something they have seen before.

Row_number() -SQL function throws error - SAP B1 2005 B - PL 36
hi experts,
when i try 2 run "SELECT * FROM (SELECT ROW_NUMBER() OVER (ORDER BY CardName) AS RowNo,CardCode,CardName FROM OCRD Where CARDTYPE='C') AS OCRD"
query in SAP B1 2005 B, PL-36 it shows an error -server throw an exception.
anybody can comment on it
thanks in advance
jithesh nambiarHi,
Problem might be with your query. Server exception error may occur while accessing large number data retrieving from the data base. It is execution type of error. What do you expect/want from your sql query?
try this query
SELECT ROW_NUMBER() OVER (ORDER BY CardName) AS RowNo,CardCode,CardName FROM OCRD Where CARDTYPE='C'
