Oracle SQL Developer needs some work

I just downloaded a copy today (1557) for Oracle 9.2i / Windows XP Pro
Oracle SQL Developer has a few glitches...
A compiled and working package (compiled in SQL*Plus and TOAD) opens and shows 2 errors in a SQL Query involving a CASE statement. Invalid CASE clause on an ELSE and unexpected token on an alias at the end of the case.
Compiling a package should display a message saying successfully compiled and the state of a package should always be on display!
Opened an SQL script but could not execute it as the icon's didn't become active.
Couldn't then run the script.
These basic problems would put any serious developer off using Oracle SQL Developer.
Also background color scheme should be gray and NOT white. White is hard on the eyes. This is just basic UI stuff.
Oracle, you need more senoir developers!

Justified to the top left of the sql window, you see the execute buttons. On the top right, you will see a drop down list box. After opening a file, this drop down list box is not selected. Select your connection and the execute buttons on the top left will enable.
For PL/SQL use a slash / at the end for it to execute.

Export Option of Oracle SQL Developer isn't working .

Hi ,
I use SQL Developer for querying Database .
The problem is that after getting data as a result of a Search operation inside Oracle SQL Developer tool , i can't able
to export those Data using export Option of Oracle SQL Developer .
Could anybody please help me on this.

Differences between TOAD for Oracle and Oracle SQL Developer?

Does someone know the advantages and disadvantages of using TOAD for Oracle and Oracle SQL Developer?
I work making reports with TOAD, but in a few days I will have to use the SQL Developer (because it´s free) unless I justify the necessity of using TOAD.
Could some that used both compare them?
Thanks,
Facundo.

Hello Facundo,
since we are rolling out new client PCs we switch from Toad to SQL Developer. Therefore I'm doing some training for the "normal" users and our developers.
Most users simply want to have access to the data in tables and views. For those there are 2 main issues:
- Filters get lost when exiting table while sorting is still applied. Since there is no way to apply filtering before entering the data tab this can become a great performance issue because sorting is applied to many many rows. For views it is sometimes impossible to open the data tab.
- Exporting date values to Excel needs some know how if you want to sort by this column in Excel, because the date is formatted as "Standard" meaning that the sorting is done as for a text column: 01.01.2009 is less than 02.01.2008. Here you have to use a workaround column with a formula (=1*<datecolumn>)
The greatest Pro is the easy sharing of connections and reports by XML files.
Our developers like the easy debugging in SQL Developer. Though they miss the feature that the source is compiled for debug automatically as in Toad. For this we have distributed a script that compiles any PL/SQL object for debugging.
There are only some Toads installed for DBAs and for users that need access to tables protected by policies that require authentification by OS user since this information is not passed under every circumstance.

Marcus

Date Parameters Toad/Oracle SQL Developer

Dear All, The code below works in TOAD but in the Oracle Sql Developer doesn't work it says the Start_date is not been declared. The ambersand doent work in Toad? Don't know why. Is there a reason for this.
I have been using Toad for a while, now they're rolling out Oracle Sql Developer as it is a free tool.

Import data using Excel and Oracle SQL Developer - I need some help

Dear friends,
I'm using Oracle SQL Developer 1.5.1 and I need to import an Excel file into a database table. If I try to import this file in XLS format, fields and headers are correctly being shown and separated, but if I press "Next" button, it simply doesn't do anything - it stays stopped.
I did some search here in this forum and it seems to me that, when you try to import a file via XLS format, SQL Developer has bugs. Is this correct?
If I save the same file in CSV format and try to import the same file, it goes ahead, but SQL Developer is not separating fields and headers correctly. It combines all CSV fields into one - let's say Column0 and fields 1;TEST;01/01/2000 below the same Column0.
Saving the file in CSV format is not a problem, taking a very little time. But I don't know how to make SQL Developer import it correctly. Could somebody please help me? Thanks in advance.
Best regards,
Franklin

Hello K,
yes, you're right. I found the following topic after posting this question here.
Re: After update to 1.5.1, import from Excel fails
I downloaded version 1.5.0 and I'll use it whenever I import data from Excel.

I need some working examples with pl/sql records and pl/sql tables.

i am new to pl/sql tables and pl/sql records. i need some working examples on pl/sql records and pl/sql tables from basics to hoghlevel.how to use then procedures and functions and packages.

i am new to pl/sql tables and pl/sql records. i need some working examples on pl/sql records and pl/sql tables from basics to hoghlevelThere is no such thing as PL/SQL "+tables+". This is a misnomer and creates the perception that a PL/SQL "table" is somewhat like a SQL table. Nothing can be further from the truth. The correct term is "+collection+" or "+associative array+". Compared to SQL tables, these are very primitive structures, very rigid structures, cannot scale, and can be quite expensive memory wise.
That is not to say do not use an associative array or collection. These are very useful tools.. but only when applied correctly. Like using a collection for a bulk fetch to transfer more rows between the PL and SQL engines and thus decrease context switching.
Unfortunately, quite often we see the row-by-row and slow-by-slow approach - where the developer uses SQL as an I/O only layer, pulls rows into expensive PL engine memory into record structures and arrays, and then process the rows there.
So before looking at working example (even the wrong approach's code will compile and run and work in practice), make sure that you know the fundamentals of correctly using the PL engine and correctly using the SQL engine. And these fundamentals can be summed up into a very basic rule:
Maximize SQL. Minimize PL/SQL+
Get this rule right, and you will have a sound foundation for writing performant and scalable Oracle applications.

ORACLE SQL Developer: DELETE Key Stopped Working???

OK, I'm an idiot, I admit it. I have ORACLE SQL Developer installed, and stupidly changed some of the menu items under Tools/ Preferences/ Code Editor. Now all of a sudden, my DELETE key does not delete, although BACKSPACE works fine. Also, the prehistoric Windows shortcut CTRL + INSERT suddenly doesn't copy any more, although it worked before in the tool, and works on everything else in Windows.
A smart person would have recorded exactly what changes they made- but I didn't.
Any idea which Preference should be changed, and what it should be changed back to???
HELP!!!! - [email protected]

Don't have to call me that blush
As I said, something I picked up on the forum... just keeping track here ;-)
As for wasting time, happens to all of us. We have to find a balance between trying to solve our own problems and asking for help (in which you have to invest a fair amount of time also).
Glad to be of help,

Oracle SQL Developer 2.1 EA1 and 1.5.5 not working on MacOS X Snow Leopard

You have started this annoying discussion.
I don't have any problems with my OS instead of you.
I have already told you what to do, if you have no idea how to do that just go and buy yourself another support subscription from your mac support.
The missing class is not available from any code-source or loader in the system. check that.
what version of JAVA do you have in your fancy OS? most of the time upgrade java to the latest version will fix the issues.
Update java from sun website not from another mac tore.

Oracle SQL Developer error - "The file-based source procedure Name is not present in the database."

I recently started working on the Oracle SQL developer. I have 'select' privileges on the QA schema and when tried to execute proc in QA. It is giving the error as 'The file-based source <procedure Name> is not present in the database. Was it compiled?'
instead 'you do not have sufficient privileges to execute this procedure'. Did research on internet but with no luck.What configuration changes needed to be done to make it work.Guide me.

Sounds like you do not have the correct privileges. What should have been granted to you by the QA user, or some other user with appropriate privileges, is...
grant EXECUTE on "QA"."<PROCEDURE_OF_INTEREST>" to "<YOUR_USERID>" ;
Note that a grant of execute on a procedure has nothing to do with grants of select on some or all of QA's tables and views.
So, as Vadim suggests, from your connection node in SQL Developer's Connections view, if you expand the Other Users node, then expand QA and look in the Procedures node, do you see the procedure of interest? If not, you cannot expect to be able to execute it from your userid's connection. And even if you do see it, you may have some other privilege that permits viewing but not executing, like...
The role SELECT_CATALOG_ROLE
The system privilege SELECT ANY DICTIONARY
And even if you do not see it there, then having certain other privileges granted to you could permit executing it in general, like...
The role EXECUTE_CATALOG_ROLE
The system privilege EXECUTE ANY PROCEDURE
Also, note that the 3.0 release is a bit dated nowadays. Upgrading to 4.0.3 production or even the 4.1 EA2 (early adopter) release will, in general, give you a better experience.
Best wishes,
Gary

How to open a package body in Oracle sql developer

How to open a package body in Oracle sql developer..any shortcut for that

I need another way to get to my package body. I'm on a locked down system, so the only way I can reference anything is if I already know the name of it. I accidentally overwrote my text document that I was using to work on it and I closed out of the package body in sqldeveloper. There must be a command, like an alter or some such. Anyone know the old fashioned way of looking at a package?

SDO_GEOMETRY displaying in Oracle SQL Developer (freezing)

Hi,
I am using Oracle SQL Developer (V 1.5.3) heavily at work, and have noticed some undesirable behaviour when the table's data tab is trying to display SDO_GEOMETRY. In this version (and subsequent ones) Developer tries to convert the geometry to WKT, instead of just displaying "sdo_geometry". I can see why this has been added in, however I am using many geometries that are quite large, and have extremely large sdo_ordinate_array/s . This is causing Developer to appear to be freezing while it runs the conversion, often hanging for many minutes at a time. I have briefly looked at V 2.1, and it appears to be the same.
Does anyone know if there is a check box option, or similar to switch this behaviour off? Limiting the number of rows returned has been suggested, but even when dealing with a STATES table the 9 rows needed for all 9 Australian states is far too large for a data tab display. If an option doesn't currently exist, it might be worth adding in to future versions of SQL developer.
regards, Jeff

Hello,
I´ve the same problem. I use version 3.0.03 (3.45) but I can´t find the possibility to change this option.
Can someone help me?

Edited by: user13373417 on 07-Jul-2010 09:06It appears you don't have a very clear understanding of how the client and the server are configured to communicate with one another.
============
A couple of important points.
First, the listener is a server side only process. It's entire purpose in life is to receive requests for connections to databases and set up those connections. Once the connection is established, the listener is out of the picture. It creates the connection. It doesn't sustain the connection. One listener, running from one oracle home, listening on a single port, will serve multiple database instances of multiple versions running from multiple homes. It is an unnecessary complexity to try to have multiple listeners. That would be like the telephone company building a separate switchboard for each customer.
Second, the tnsnames.ora file is a client side issue. It's purpose is for address resolution - the tns equivalent of the 'hosts' file further down the network stack. The only reason it exists on a host machine is because that machine can also run client processes.
Assume you have the following in your tnsnames.ora:
larry =
(DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = myhost)(PORT = 1521))
    (CONNECT_DATA =
      (SERVICE_NAME = curley)
)Now, when you issue a connect, say like this:
$> sqlplus scott/tiger@larrytns will look in your tnsnames.ora for an entry called 'larry'. Next, tns sends a request to (PORT = 1521) on (HOST = myhost) using (PROTOCOL = TCP), asking for a connection to (SERVICE_NAME = curley).
Where is (HOST = myhost) on the network? When the request gets passed from tns to the next layer in the network stack, the name 'myhost' will get resolved to an IP address, either via a local 'hosts' file, via DNS, or possibly other less used mechanisms. You can also hard-code the ip address (HOST = 123.456.789.101) in the tnsnames.ora.
Next, the request arrives at port 1521 on myhost. Hopefully, there is a listener on myhost configured to listen on port 1521, and that listener knows about SERVICE_NAME = curley. If so, you'll be connected.
What can go wrong?
First, there may not be an entry for 'larry' in your tnsnames. In that case you get "ORA-12154: TNS:could not resolve the connect identifier specified" No need to go looking for a problem on the host, with the listener, etc. If you can't place a telephone call because you don't know the number (can't find your telephone directory (tnsnames.ora) or can't find the party you are looking for listed in it (no entry for larry)) you don't look for problems at the telephone switchboard.
Maybe the entry for larry was found, but myhost couldn't be resolved to an IP address (say there was no entry for myhost in the local hosts file). This will result in "ORA-12545: Connect failed because target host or object does not exist"
Maybe there was an entry for myserver in the local hosts file, but it specified a bad IP address. This will result in "ORA-12545: Connect failed because target host or object does not exist"
Maybe the IP was good, but there is no listener running: "ORA-12541: TNS:no listener"
Maybe the IP was good, there is a listener at myhost, but it is listening on a different port. "ORA-12560: TNS:protocol adapter error"
Maybe the IP was good, there is a listener at myhost, it is listening on the specified port, but doesn't know about SERVICE_NAME = curley. "ORA-12514: TNS:listener does not currently know of service requested in connect descriptor"

Oracle sql developer Data Modeler -er diagram

Hi
I tried to Oracle sql developer data modeler for show relational ER diagrams.
Tables are came on data modeler but not shown relations between tables.
like this
How can show relations between tables?
http://i54.tinypic.com/30wxq1e.jpg

SDDM cannot create an ER diagram with only simple table definitions. It requires that primary keys (PKs) and foreign keys (FKs) be defined first. My guess is you imported these table designs from an existing database. If so, that database does not contain those constraints. (I have found this to be an issue in many organizations over the last 20 years - including my current job). You will have to determine:
1. The PKs for each table (either via data profiling or talk to someone who "knows" what they are supposed to be, or by reading application logic/code used to manage the tables).
2. The FKs between the tables. You may be able to guess some of that based on column names, otherwise you will have to figure them out (same as above)
Then you can update the model in SDDM with the PK definiions (manually). You must do that first before you draw in the FKs between the tables. Now if you want a true Entity Relationship model you need create a logical model from this relational model. The SDDM utility for that will convert the tables to entities and the FKs to relationships.
I have the basic steps with screen shots outlined in a presentation I gave in Denver in late 2009. It was an earlier version of SDDM but the basics are the same. You can find the presentation is here: http://www.rmoug.org/QEW2009/SQL%20Developer%20Data%20Modeler%20(2).pdf. Start at about slide 12.

SQL Server table capture using Oracle SQL Developer

Hello,
I need to know how to set up the Oracle SQL Developer to captuer SQL Server table with correct field precision. For some reason, all NVARCHAR field precision sizes are the double of the original precision size after capturing the table.
Example:
SQL Server table 'A' with the following field:
name NVARCHAR( 50)
after table capture becomes:
name NVARCHAR2(100)
which is double of the original precision.

--tsql correction
merge into md_columns m
using(
select md_col.precision as prec, md_col.column_name,md_col.rowid as row_id
FROM md_schemas md_s
join md_tables md_tab on md_tab.schema_id_fk = md_s.id
join md_catalogs md_cat on md_cat.id = md_s.catalog_id_fk
inner join md_connections con on md_cat.connection_id_fk=con.id
join md_columns md_col on md_col.table_id_fk = md_tab.id
where --md_s.created_on = (select max(created_on) from md_catalogs)
con.name like '%(corr%)'
and md_col.column_type in ('nchar','nvarchar')
) merge_clause on (m.rowid = merge_clause.row_id)
when matched then update set m.precision = merge_clause.prec/2
that works, as long as you don't forget to commit like i did....
hope it helps
