Time conversion problem using sql developer

Hi,
I migrated my data from sql server 2 oracle 10g using the following procedure
1.Created a ODBC from Access-2003 to sql server
2.Imported the tables
3. Used Quick migrate feature in SQL DEVELOPER 2 migrate the data to oracle....
Now when i view the data in my forms (oracle forms 10g)...... along with time a date is also appearing in the time field...when actually thrz no date field present
Ex;
In access and sql server table it is suppose
9:00 Am
IN oracle forms it is appearing as
12-4-2010 9:00 Am
can any 1 help me out how to remove this date which is appearing in all the records..??!!!

The datatype of that column is now 'Date'. Anyway, timestamp without date will not be of much help in date calculations. If you do not care about the date portion, simply do a to_char and display as mentioned here: to_char(<your column name>, 'HH24:MI:SS AM'). Ensure that <your column name> datatype is not Character, if it so, you will get ORA-01722 error.

Problem when connecting sql server 2005 using SQL developer

Hi,
I installed Sql developer and I am trying to connect sql server 2005 using windows authentication. I had previously the SSO folder problem saying the path is missing in java.library.path. I copied the SSO folder into Sqldeveloper directory. I changed the settings under computer management->services and applications->sql server configuration manager->sql server 2005 network configuration ->protocols for sqlexpress->I enabled TCP/IP.
Now I am getting an error saying "Failure-can not open user default database.Login Failed. Login failed for user ...".
I am able to connect thru ODBC driver using windows authentication.
Any help on this is highly appreciated.
Thanks in advance,
Lakshmi

Hi Martin,
Your solution has solved my problem too. Thanks for posting these workaround fixes :-)
However, there seem to be a problem with datetime fields. The query:
select getdate()
returns something like: oracle.datetimestamp.@1aed4
Is there a way to get around with this? Otherwise, using SQL Developer as a client for SQL Server doesn't serve the right purpose when we cannot access simple date fields :-)

Problems using SQL*Loader with Oracle SQL Developer

I have been using TOAD and able to import large (milllions of rows of data) in various file formats into a table in an Oracle database. My company recently decided not to renew any more TOAD licenses and go with Oracle SQL Developer. The Oracle database is on a corporate server and I access the database via Oracle client locally on my machine. Oracle SQL Developer and TOAD are local on my desktop and connected through TNSnames using the Windows XP platform. I have no issues with using SQL*Loader via the import wizard in TOAD to import the data in these large files into an Oracle table and producing a log file. Loading the same files via SQL*Loader in SQL Developer, freezes up my machine and I cannot get it to produce a log file. Please help!

I am using SQL Developer version 3.0.04. Yes, I have tried it with a smaller file with no success. What is odd is that the log file is not even created. What is created is a .bat file a control file and a .sh file but no log file. The steps that I take:
1.Right click on the table I want to import to or go to actions
2. Import Data
3. Find file to import
4. Data Preview - All fields entered according to file
5. Import Method - SQL Loader utility
6. Column Definitions - Mapped
7. Options - Directory of files set
8. Finish
With the above steps I was not able to import 255 rows of data. No log file was produced so I don't know why it is failing.
thanks.

Demonstrating PL/SQL Functions Using SQL Developer

Good afternoon,
I'm starting to write some PL/SQL functions to replace some of the SQL that I use most frequently. A couple of very simple examples would be:
create or replace function func_test (p_1 number) return number
is
x number;
y number;
begin
x :=1;
y :=2;
return p_1 * x * y;
end func_test;
create or replace function func_test2 (p_1 varchar2) return varchar2
is
return_val varchar2(10);
begin
select p_1 into return_val from dual;
return return_val;
end func_test2;
However, at my workplace I haven't been granted create function privileges yet until I can demonstrate some examples, which is understandable.
For the time being, without these privileges, is there a way I can build/test functions in principle locally using SQL Developer without the need to write the functions to our database? I.e. can I demonstrate the above in SQL Developer, but without wrapping in create or replace syntax?
I hope this isn't too vague.
Using Oracle 11gR2 (not logged in to workplace database at the moment for specific version no.)
SQL Developer 3.4
Thanks,
TP

populating test DB with data is a solvable problem.
You don't need client data to test code (functions).
You only need sample test data; which generally is less than a few dozen records per table.
Absolutely, of course. Our client database is pretty messy though, and includes data prior to the implementation of more recent business rules that I need to take account of. Useful perspective though, thanks.
rp0428 02-Nov-2013 19:14 (in response to TinyPenguin)
Sure, but then I wouldn't have access to all the data in our client database to test functions under various circumstances.
Huh? Why not? It's your database so what keeps you from creating a database link to your client database where all the data is?
Also, I suppose it's not good practice to constantly write/replace/drop functions to/from a database when developing them? Better to test the function in principle and then write to the database?
Huh? Why not? What you think a dev database is for if not for development?
Based on your two posts so far in this thread it's understandable why they don't want to give you privileges yet. Those sample 'functions' you posted are NOT a good use for functions.
In sql developer you can just create and save the queries you use most often. There is no need to create functions for that.
But if you do need an anonymous function now and then just create one using sql*plus syntax:
Our IT department are pretty sensitive about how they allow access, even to the dev environment. As you've identified, I'm not naturally a programmer so the option to play around with the data to develop some representative examples about how we can simplify and devolve SQL reporting to more members of staff is useful to me. I just wrote those two function quickly for the purpose of posting some sample data, which I thought would be helpful. Thanks for illustrating how to return their output using an anonymous block.
FrankKulash 02-Nov-2013 19:13 (in response to TinyPenguin)
Hi,
The obvious solution is to get the privileges. If your employer really wants you to do something, they need to give you the necessary privileges to do it. It's silly for them to tell you to do something, but refuse to let you do it.
Failing that, you can install Oracle on your own machine, as suggested above. It's free and legitimate if you're only using it for learning and developing. Oracle Express Edition is very easy to install.
As a last resort, you can write functions and procedures that are local to an anonymous block, like this:
Thanks Frank. Yeah I'm going to speak with our DBA next week about privileges. I've got XE/SQL Developer installed on my own computer - I wrote those sample functions using them - I just wasn't sure how to call/return anonymous blocks as both you and rp identified to develop at work as an interim solution.
Thanks a lot All,
TP.

Create statspack report using sql*developer

Hello,
While connecting with PERFSTAT user I can not create statspack report using SQL*Developer:
@?/rdbms/admin/awrrpt
Error starting at line 1 in command:
@?/rdbms/admin/awrrpt
Error report:
Unable to open file: "?/rdbms/admin/awrrpt.sql"
Actually, my problem or question is that how can PERFSTAT user can generate statspack reports from a Client side. What is the other way a non-dba can see the snapshots histroy and generate report (by using perfstat user ) while joing tables or using views?
Thanks a lot.
Best Regards

Hi,
for awr reports @?/rdbms/admin/awrrpt (you need EE+Diagnostic Pack) there is a solution.
Grant execute dbms_workload_repository to <user>;
Grant select_catalog_role to <user>;
get all SNAP_IDs
SELECT   TO_CHAR(s.startup_time,'YYYY.MM.DD HH24:MI:SS') INSTART_FMT,
         di.instance_name INST_NAME,
         di.db_name DB_NAME,
         s.snap_id SNAP_ID,
         TO_CHAR(s.end_interval_time,'YYYY.MM.DD HH24:MI:SS') SNAPDAT,
         s.snap_level LVL
FROM    dba_hist_snapshot s,
         dba_hist_database_instance di
WHERE   di.dbid = s.dbid
         AND di.instance_number = s.instance_number
         AND Di.Startup_Time = S.Startup_Time
ORDER BY snap_id desc;
Select * From Table(Sys.Dbms_Workload_Repository.Awr_Report_Html(DBID, 1, BEGIN_SNAP_ID, END_SNAP_ID));
For statspack i don't know a solutuion. I think the best idea is, create a job to make the statspack report on the server side and access it via external tables or mail them forward to you.
Best regards

IBM DB2 to Oracle Database Migration Using SQL Developer

Hi,
We are doing migration of the whole database from IBM DB2 8.2 which is running in WINDOWS to Oracle 11g Database in LINUX.
As part of pre-requisites we have installed the Oracle SQL Developer 4.0.1 (4.0.1.14.48) in Linux Server with JDK 1.7. Also Established a connection with Oracle Database.
Questions:
1) How can we enable the Third Party Database Connectivity in SQL Developer?
I have copied the files db2jcc.jar and db2jcc_license_cu.jar from the IBM DB2 (Windows) to Oracle (Linux)
2) Will these JAR files are universal drivers? will these jar files will support in Linux platform?
3) I got a DB2 full privileged schema name "assistdba", Shall i create a new user with the same name "assistdba" in the Oracle Database & grant DBA Privillege? (This is for Repository Creation)
4) We have around 35GB of data in DB2, shall i proceed with ONLINE CAPTURE during the migration?
5) Do you have any approx. estimation of Time to migrate a 35 GB of data?
6) In-case of any issue during the migration activity, shall i get an support from Oracle Team (We have a Valid Support ID)?
7) What are all the necessary Test Cases to confirm the status of VALID Migration?
Request you to share the relevant metalink documents!!!
Kindly guide me in-order to go-ahead with the successful migration.
Thanks in Advance!!!

Hi Klaus,
Continued with the above posts - Now we are doing another database migration from IBM DB2 to Oracle, which is very less of data (Eg: 20 Tables & 22 Indexes).
As like previous database migration, we have done the pre-requirement steps.
DB Using SQL Developer
Created Migration Repository
Connected with the created User in SQL Developer
Captured the Source Database
Converted Captured Model to Oracle
Before Translation Phase we have clicked on the "Proceed Summary"

We have seen only "Missing" in the chart, also we couldn't have any option to trace it in Log file.
Only after the status is VALID, we can proceed with the Translation & Migration PHASE.
Kindly help us how to approach this issue now.

Problem using SQL Loader with ODI

Hi,
I am having problems using SQL Loader with ODI. I am trying to fill an oracle table with data from a txt file. At first I had used "File to SQL" LKM, but due to the size of the source txt file (700MB), I decided to use "File to Oracle (SQLLDR)" LKM.
The error that appears in myFile.txt.log is: "SQL*Loader-101: Invalid argument for username/password"
I think that the problem could be in the definition of the data server (Physical architecutre in topology), because I have left blank Host, user and password.
Is this the problem? What host and user should I use? With "File to SQL" works fine living this blank, but takes to much time.
Thanks in advance

I tried to use your code, but I couldn´t make it work (I don´t know Jython). I think the problem could be with the use of quotes
Here is what I wrote:
import os
retVal = os.system(r'sqlldr control=E:\Public\TXTODI\PROFITA2/Profita2Final.txt.ctl log=E:\Public\TXTODI\PROFITA2/Profita2Final.txt.log userid=MYUSER/myPassword @ mySID')
if retVal == 1 or retVal > 2:
raise 'SQLLDR failed. Please check the for details '
And the error message is:
org.apache.bsf.BSFException: exception from Jython:
Traceback (innermost last):

Before running sql developer i install the oracle instant client and sql plus, i use the same tnsnames.ora file as my windows machine and sqlplus (in snow leopard) connect perfect.
i set the path of my tnsnames in the setup of sql developer but i can't do it work.
Anyone can help me please? thanks a lot.

Error in Migration Repository using Sql*Developer Migration Workbench

To migrate a MS access mdb database to Oracle using Sql*Developer Migration Workbench, I try to create first the the Migration Repository in SQL*Developer.
The repository is created, but under PACKAGES I could see that package MD_META has been compiled with errors.
PACKAGE BODY AO_PERSONAL.MD_META@DMCAPX (AO_PERSONAL):
Error(27,2): PL/SQL: SQL Statement ignored
Error(30,23): PL/SQL: ORA-00904: : ungültiger Bezeichner
Well, when I ignore this and continue with the next step of the migration process "Capture Microsoft Access Exported XML file" to create the Captured Model, I get the following error message:
ORA-04063: package body "AO_PERSONAL.MD_META" enthält Fehler ORA-06508: PL/SQL: aufgerufene Programmeinheit : "AO_PERSONAL.MD_META" konnte nicht gefunden werden ORA-06512: in "AO_PERSONAL.MD_PROJECTS_TRG", Zeile 3 ORA-04088: Fehler bei der Ausführung von Trigger 'AO_PERSONAL.MD_PROJECTS_TRG'
Target database RDBMS is Oracle Database 10g Enterprise Edition Release 10.2.0.3.0. So the proposal of note 427916.1 to create the Repository in a 10.2 RDBMS does not solve the problem.
I even tried to use the Quick Migrate feature in SQL*Developer, but got the same error message.

"inserted value too large for column"
Is there a LOGON trigger on the database or user ?
I'd be surprised at SQL Developer trying to insert data into anything on connect.
I'd suspect code being executed by the database, maybe using a MODULE or PROGRAM from v$session or USERENV / SYS_CONTEXT.

Reconnect opening an Oracle Table using SQL Developer 3.0 in Windows 7.

Downloaded SQL Developer 3.1.07 and placed a copy on both Windows XP Pro. and Windows 7 Pro. No issues using SQL Developer under Windows XP, Oracle 10g client driver. However, under Windows 7 (32-bit or 64-bit PCs), Oracle 10g or 11g client driver, when I click a table name to display the 'Columns, Data, Constraints, ...' fields - I receive a Reconnect message: Your database connection has been reset. Any pending transactions or session state has been lost." I am able to view the Data, Contraints, Grants, ... fields, except for Columns field (no data). Also executing SQL statements to query any of the tables returns expected data. Right-click on database connection shows 'Connect' and 'Reconnect' greyed out, so appears connection exists. So why is the Reconnect message happening? And why can I not see my field definition under Table Columns?

Thanks, I'll survive. Just my luck, the first item I try to anon. debug didn't work! :)
thanks, hopefully this problem will be few and far between

Can we use SQL developer tool to READ/WRITE BerkeleyDB by any means

We use Berkeley Db as a persistent database, which holds data less frequently changed data. Can is it possible to use SQL Developer tool or any other front end tool that can connect and communicate to Berkeley db file for INSERT, UPDATE, DELETE records.

I assume you're referring to Berkeley DB SQL (BDB SQL API).
SQL Developer is not certified to work with BDB SQL; see the SQL Developer Certifications page.
Something similar was asked some time ago, about connecting JDeveloper to BDB SQL; see this Re: How connect Oracle JDeveloper 11g to Berkeley DB 11g. The SQL tools in JDeveloper and SQL Developer are similar and built on the same components, so my answer there can be extended to SQL Developer as well. While you can probably have SQL Developer properly connect to a BDB SQL database, I am afraid you won't be able to do more than just viewing the data; likely any attempt to generate DDL or DML statements, export data, or run DML statements against the database will fail.
If you migrated to BDB SQL from SQLite and were using a front-end tool for SQLite, it should be possible to use that with BDB SQL as well.

Andrei

The connection export function it's available in 2.1.1.64, you need to right click on the main Connections node, and it will allow you to export all or part of the current connections, or import from a previously exported file.
As for the highlight statement feature it's available in SQLDeveloper; actually you do not even have to highlight the required statement, as long as you take the habit of ending every statement with a ";", in this case you only need to place the caret inside the statement and SQLDeveloper will automatically highlight it for you (if you want to manually highlight a statement you can still do so without problems).
Finally as a last try to solve your connection problem without having to call for network support you could try to check
Preferences -> Database -> Advanced -> Use OCI/Thick DriverThis will force SQLDeveloper to use your oracle client for connections instead of it's native JDBC based connections (even if you use TNS based connections you will still use JDBC unless you have this checked).
As for other graphical tools for Oracle there are many both free or for a price.
1) In the for price world Toad stands out, i heard of a free option too but I'm not sure of the limitations.
2) For free you can use DBVisualizer which is fairly good (never used it too much thou).
3) Finally there is SQuirreL which is both free and open source but it has fairly basic functionality compared to the two above.
Obviously there are many others, but IMHO few will provide you with the same functions of SQLDeveloper or Toad for Oracle databases
