SQL Developer not fetching data tables while writting query

HI , I have recently started using SQL developer 2.1, the problem i face is that SQL DEVELOPER is not showing the tables names while writting the query, we have more than 5000 tables and each table name cannot be remembered.
Thanks
Essa

I'm using the Mac version of SQL Developer (Version 2.1.1.64 | Build MAIN-64.45) and I'm having similar problems. I'm currently using OS X Snow Leopard.
The issue does not happen consistently: If I start writing an anonymous block in a new SQL window, the Completion Insight features works well. I can start typing a name of a package (of which there are many in our db) and I'm quickly provided a list matching what I've typed so far. This is also true of variables, functions and procedures within the packages after I type a period following the package name.
However, if I open an existing package body and start editing, the Completion Insight feature becomes less reliable. If I move my cursor to the beginning of the main block of one of the package body's internal procedures, Completion Insight works. As I move down the package and try to insert new code, Completion Insight stops working. I should note that this package body I'm working with has no errors and compiles fine. I'm not sure what this indicates...whether it's an issue with the editors internal parser or some other issue.
I'm not sure the best method for starting SQL Developer via the console window on the Mac. I found the following sh file which does launch it from terminal:
/Applications/SQLDeveloper.app/Contents/MacOS/sqldeveloper.sh
This does launch the application. As I navigate around and follow the instructions you had given (including ctrl-space) I see no output generated out to the console (errors or other messages).
I'm happy to assist in further debugging. Having Completion Insight work consistently will certainly increase my productivity with the tool.
Thanks in advance for any help you may provide.

SQL Developer Not displaying Date columns

I installed SQL Developer on my machine today and when i query for data I don't find any value in the columns which are of DATE datatype.
For Eg if i says select * from dual; i get null as output.
Can anyone confirm if this is happening to you also or if there is some problem with my installation.

Dates work fine for me.
What value do you get for your NLS_DATE_FORMAT parameter with the following query:
select parameter, value from nls_session_parameters where parameter = 'NLS_DATE_FORMAT';
You can change the NLS_DATE_FORMAT as in the following example:
alter session set nls_date_format = 'DD-Mon-YYYY';
Also, the column in the dual table is not actually in date format - try "select sysdate from dual;" instead.

Newbie blues: Oracle Sql Developer showing different data from Sqlplus.

Newbie blues: Oracle Sql Developer showing different data from Sqlplus.
First of all; it would be difficult to know less about Oracle than myself.
I just installed a recent copy of the server and am running SQl Developer 3.2.20.10.
I made a small test table , borrowed some pl sql code to add rows, then wrote code to delete some rows. Lots of fun.
In SQL Developer “Select * from t1;” now shows 7 records, which seems right.
I wanted other views of the data and so logged in from the command line using SQLPlus.
The same code here shows the table prior to the delete, with 600 plus rows. Needless to say I’ve logged out and back in again, with no changes.
No fun ! What am I not understanding here ?

did you ever actually issue COMMIT so other session can see the changed data?

Can I use Oracle SQL Developer to "Move" data?

Hello,
I'm new to Oracle and I'm trying to use Oracle SQL Developer to export data from one table (on server A) to another table (on sever B). I'm able to create a .ldr file but I don't know how to use the .ldr file in Oracle SQL Developer? I would appreciate any help you can provide.
Thanks!

Hi,
The name of tables are different ?
If I understood then try this below:
e.g:
C:\> exp user/password@connectionA file=maytable.dmp tables=SAFETYADMIN_TBL_0022_43
C:\> imp user/password@connectionB file=mytable.dmp full=y
After this import, then you can:
[pre]
C:\>sqlplus user/password@connectionB
SQL> insert into SAFETYUSER_TBL_0022_44
select * from SAFETYADMIN_TBL_0022_43;
SQL> drop table SAFETYADMIN_TBL_0022_43;Feedback if this is not that you want.
Cheers

SQL Developer not migrating Sybase data

Hi,
I am trying to migrate data using the SQL developer tool from a Sybase database to Oracle 11g. When using the Migration Repository, I am able to recreate the schema but am not able to export the database content. (i.e. Not able to do the Data Move). I tried doing a Offline migration but the generated datamove files does not have any content. Anyone aware of any issue with the data migration tool with SQL developer ?
I have tied exporting data from the table directly to generate SQL inserts but even this is not helping. Any suggestions ?
Regards,
Nelson

Hi Nelson,
Could you detail the exact steps you followed and what options you chose at each of the panels in the migration steps ? this will help to see where you may be having problems.

Oracle sql developer import .xls data for table

When I import data from .xls how come it doesn't show me an message when the import is done? How do i know when it is done? How come I don't see all the rows. When I do a select count(*) from table I come up with different numbers every time I do it.
Once I do create the table with the data how do I generate the scripts for it. I was able to get the scripts to create the table ->table->Right click -> Export ddl .
But how do I get the script for the "Insert statements"

Hesh,
The numeric value of 39057 in an Excel cell does display as 06-Dec-2006 when applying a date format DD-Mon-YYYY, so you are getting the right value - just not the right formatting.
Which column type are you trying to import the XLS date into? If you are not loading the value into a date field, SQL Developer is probably just loading the base excel value of 39057.

SQL Report not showing data - available in SQL Workshop and SQL Developer

I am having an issue with developing a SQL Report in APEX 3.2.1. I run the code in both SQL developer and SQL Workshop and I get data pulled back (both against my development environment). When I run the same code in a SQL Report region, it returns no data available. Does anyone have any idea what would be causing this? Other regions on the page accessing different tables in the same schema return data without issue. Any help would be appreciated.
Thanks
Freddie

Could you explain the last comment a bit more. Here is a bit more info just in case I touch on the info with it. The db schema is BPAMGR, the Workspace is BPAMGR. We use the same schema for all of our reporting. All of our tables are in the same schema. We don't use any tables outside of this schema. Our APEX workspace has been associated to only this schema. The tables are able to be queried by SQL Workshop in the same APEX instance that the report application is under.

SQL Developer 3.0 data modeler print-to-pdf not working

I am working in Windows XP. I am running SQL Developer version 3.0.04, which now includes a full-featured version of the Data Modeler. I have run into a problem with this version, which did not occur in the stand-alone version of the Data Modeler.
When I try to print a data model diagram [File -> Data Modeler -> Print Diagram -> To PDF file], a PDF file is generated. When I try to open that PDF file with Adobe Reader (version 9.4.3) I get the following error message:
"Adobe Reader could not open 'finename.pdf' because it is either not a supported file type or because the file has been damaged(for example it was sent as an email attachment and wasn't correctly decoded)."
Furthermore, the size of the file in question is 0 bytes. When I use the same process in the stand-alone version, a readable PDF file is created whose size is 858 bytes.
The 'print to IMAGE file' option works well in both versions.
Any help resolving this would be appreciated.

I am having almost same problem. PDF file is genereted about 400K but blank.

SQL Developer: Not able to view tables

I am new to sqldeveloper and oracle products. I've recently installed sqldeveloper onto my pc, i am able to connect to the database but when i try and expand the tables item in the treeview i dont get the tables displayed and the error Warning, unhandled exception:Closed connection is shown in the logging page at the bottom. I have uninstalled the oracle client, jdk but still i keep getting this problem.
Current versions are
Operating System= Windows 7 32bit
SQLDeveloper=3.0.03
JDK=1.6.0_21
Oracle Client=11g

It looks like it may be a privilege issue.
I ran SQL Developer with 'IncludeConfFile sqldeveloper-debug.conf' in the 'sqldeveloper.conf' file. I got the following log output when I connected to XXAPI (which hangs) and XX (which works)
For XXAPI, 'oracle.dbtools.db.DBUtil' generates
Prepared:SELECT object_type type, SYS_CONTEXT('USERENV','CURRENT_SCHEMA') owner, object_name, null column_name, null column_id, null data_type
FROM user_objects

union all
SELECT object_type type, SYS_CONTEXT('USERENV','CURRENT_SCHEMA') owner, object_name, null column_name, null column_id, null data_type
FROM user_objects
WHERE object_type ='VIEW' and object_name not like 'BIN$%' and rownum <=50
and the following log message

For XX, 'oracle.dbtools.db.DBUtil' generates
Prepared:

Sql developer not showing table/view names

I just set up a new machine, the database settings are same as in the old machine. But I cannot see the table/view names when expending the "+" sign before Tables or Views. When using "select * from tab", the result of all tables/views returns correctly. Is there any other settings I missed?
I'm using Oracle Database 10g Express Edition, and Oracle SQL Developer 1.5.5.

The same issue exists in 2.1.1.64.39
All of a sudden: list of tables empty, views still viewable,tables are still there though.
In the logging window I get ora-904 messages on sys.o.name

Some SQL fields not showing data in Crystal XI R2

I have a report that is using a stored procedure. In this stored procedure we have many fields that are being passed over to Crystal. A small portion of these fields do not show any data when you browse them in Crystal. But when you check on the SQL Server 2005 side, they contain data. So we know that the issue is probably on the Crystal side because there is data on the SQL side.
I originally thought that the problem may be caused by Null values in the database, but I used Crystal to convert the Null's to numeric zero if it was a number, and still there was no data showing up.
Also in the stored procedure, we are passing 2 parameters a start and end date. But that seems irrelevent to why some of the fields are not containing data like they should.
Why would some fields show no values at all, and some fields shows values?
Any ideas on how to correct this situation so data will show up for all the fields like they are suppose too?
Thanks everyone for their help!

Hi Levi,
Pleaase check the following :
1. Other than storedprocedure are you adding any tables to your report ? If so, check the links between your stored procedure.(Through Database Expert)
2.Write the following formula to find out whether the database fields contains values or not.
if isnull() or = " " Then
"This Field is Empty"
Else
Drag and dwop this formula in your report to get the field values.
Thanks,
Sastry

SQL Developer keeps dropping my table cols!!

Howdy,
Really getting to the end of my tether with SQL Developer now, as it likes to drop all my columns (usually leaves one for me which is nice of it) in my tables if I decide to make a change to it.
for example, if I where to change a column to be NOT NULL it will throw an error saying (Could not drop all columns) and I look at my table and wow, I have ONE column left in the table and all my data is then f**ked. Or if I want to edit a constraint, or a index it will do the same! Its random cos it wont do it all the time.
This is unacceptable really, cos I then have to rebuild the DB table and get all contraints back to it. I would NEVER EVER consider using this for live data, oh that would be catastrophic!
Does anybody else have this problem? Is there anything I can do to maybe avoid the problem occuring again?
Any help will be appreciated!

Hi,
Sorry, this hasn't just started happening, been doing this ever since I started using SQL Developer, so now I just try to steer clear on making changes that I know has potential of causing me trouble.
At the moment I am on:
Vista 64bit
SQL Developer 1.2.1 Build 32.13
Latest version of Java (only downloaded it last week.
But this problem also occured on Vista 32bit witht he same version of SQL Developer. I tried it with the Java included version, and java installed on my machine, but it still done it.
I mainly get the problem if I Right Click > Edit and change Indexes or foreign key details.
I'm running from /bin/ at the moment as I am in a 64bit environment, but it makes no difference what .exe I use!
The error I get is always "Unable to drop all columns"... this is when I was NOT dropping columns, I was just making a change, but I assume oracle drops them and rebuilds it or sumin (im no DBA). Incidently it's usually a DATE column I am left with after its decided to drop all my other columns?

Profiler in SQL Developer not working

When I run the profiler in SQL developer , I get the following error.
"Directory exists; check if /tmp exists on file system, and oracle has permission to write there. "
This error sounds like an UNIX error but I am running SQL developer on Windows 7 (64) OS. Has anyone seen this or knows how to get around it.
Thanks so much..

Hi,
According to the SQL Developer 3.1.04.72 documentation, the "get" command (among others) is not supported:
Help|Table of Contents|SQL Developer Concepts and Usage|Using the SQL Worksheet|SQL*Plus Statement Supported and Not Supported...
so options are limited. If sqlplus is accessible and using it as an "external tool" won't conflict entirely with local policy, these links might interest you:
Re: sqlplus vs sqldeveloper
Easy Connect and sqldev.conn issues
Otherwise you may add a feature request for this on the SQL Developer and see if such an enhancement is a priority for the community.
