Data is encrypted when you use SQL * Net

Hello

I'm curious to know if the data that is transmitted through SQL * Net is encrypted or clear text - which means that it will be possible for someone read data that is sent from database to log on user or vice versa.

Thank you
SS

I'll change the response of sb92075 to say that the transfer of normal data packets aren't encryped by default however the advanced security option can be used to encrypt all packets of sqlnet.

I also believe that oracle encrypts the password in a package of authentication.

Error occurs when you use SQL Server 2012 assessment vs window detail of the object in window 7 - KERNELBASE.dll exception 0xe0434352

Hello

Error occurs when you use SQL Server 2012 assessment vs window detail of the object in window 7. I use the window of the object but the detail of the objects window arrives and immediately SQL Server stops with the error below and then opens again. I didn't find any help with this specific error is but suspect there is a problem between SLQ Server 2012 et.NET Framework 4. Unfortunately, I do not know what it takes in this regard.

If the data is empty when you use to_date(?,'yyyy/mm/dd')
Thank you
Be more specific.

You try to insert this in a column that is defined as not null?

If so, you can choose a default value for the value that you want to use if the user leaves the field to the white screen.

Or, better yet, use the validation of the front to prevent them from going into an empty space (or perhaps failed it there).

However, if you still want to do it in the DB:

Insert into table1 (non_null_date_col)
values (to_date (nvl (?, '' 2199/12/31), "dd/mm/yyyy"));

ORA-22901 when you use sql (no space) union
I have a number of spatial views. I want to take some common fields and a column of the geometry of each of these points of view and use sql union to get a single view of all the data that meet certain criteria.

Example:

/ / DESC View1
Identification number,
Comment varchar2 (200)
geom mdsys.sdo_geometry

View2 DESC
Identification number
Comment varchar2 (200)
geom mdsys.sdo_geometry

I want to do this:
Create view viewUnion as
SELECT id, comment, geom, viewname 'View1' View1
Union
SELECT id, comment, geom, "view2 viewname of view2;

The creation of the view is accepted, but when I try select * from viewUnion; I get ORA-22901.

Can I get there from here? Is there something about the space object that prevents the union from working?

Any guidance will be appreciated.

Thank you
View of the "union all" is right for your application?
i.e.

Create view viewUnion as
SELECT id, comment, geom, viewname 'View1' View1
Union of all the
SELECT id, comment, geom, "view2 viewname of view2;

[Issue] How data is transferred when you use BlackBerry (NFC) Tag? WiFi Direct? Bluetooth 2.1? Bluetooth 3.0?

Hello

I saw a bunch of videos of demonstration of tag BlackBerry of all the cool things you can do with the NFC, but it wondered, what happens if all my other antenas wireless, WiFi and Bluetooth, are out of?

NFC can be used to transfer data, but it is not good for large quantities. I looked a little further and I found this cool video showing the difference to use Bluetooth 2.1, Bluetooth 3.0 high speed and Wifi Direct to transfer large files, such as videos. BB10 already does support Wifi Direct? Bluetooth 3.0 high speed?

I hope that BB10 supports ALL the performance and maximum compatibility.

I don't know where to post this question so here's. Please move was a better place. I think that the community needs a session of general development for wider issues.

See you soon!

Hello

Tag BlackBerry, and the APIs available for developers will automatically perform the best way to transfer the data. NFC supports something called "connect transfer" and are the largest payloads or certain types of data (photos, for example) rather than by peer-to-peer NFC, NFC mode data transfer is just used to negotiate alternative transport. In the case of the BlackBerry smart phones, this alternative will be bluetooth.

For users of touch devices, there is a brief 'conversation' between the devices on the NFC and this translates into a bluetooth connection set up and data transfer initiated through the bluetooth connection faster. This is all without the usual matching process. After reaching the stage of bluetooth devices need closer will be of course.

The same principle applies to both 7 BlackBerry and BlackBerry 10. In fact talk us a bit about this in our latest article on BlackBerry 10 NFC API:

http://supportforums.BlackBerry.com/T5/native-development/BlackBerry-10-sharing-using-NfcShareManage...

I hope this helps.

Correct way to use Bind variables when you use an interface to MS SQL Server
Hey,.
I have some difficulty to find how to use bind variables in a view, when you use an interface to MS SQL Server. For some reason when I use an ApplicationModule who has a library of MS SQL Server JDBC loaded and I try to click on OK when you change the following query:

SELECT kit_status, component_id
OF numbered_inv
WHERE trialname =: 1

I get an error stating that ' SQL Query Error Message incorrect syntax near ':'. JDeveloper is compatible with SQL server for bind variable as this query works fine if I replace the: 1 with a Word to say "Test test".

Thanks in advance

Impact on performance when you use the LONG data type
Hi all

Only I have a doubt about the use of LONG data type

I use the data type LONG for some columns in a table and I created indexes on the columns separately, but these column values can be easily fit into the varchar data type.

(Just to see the performance on this issue)

Suppose that a common select query with WHERE condition on any of the column which has LONG data type will affect the performance of the query?

Please explain.

Thank you
(1) the LONG (and LONG RAW) data types have been depricated for quite a while. Oracle has been strongly recommends that you move to 8.1.5 CLOB and BLOB data types. Why you use the LONG data type? You're still on Oracle 7?

(2) have you tried to write a query that has a WHERE condition that refers to a LONG column? In general, you can not because it does not support the type of data LONG. For example
```
SQL> ed
Wrote file afiedt.buf

  1  create table a (
  2    col1 varchar2(30),
  3    col2 long
  4* )
SQL> /

Table created.

SQL> select * from a where col2='abc';
select * from a where col2='abc'
                      *
ERROR at line 1:
ORA-00997: illegal use of LONG datatype
```
LONG data types are a royal pain to work with. They also have implications on the performance of wicked on the client.

Is there a way to simplify the addition of data in the worksheet when you use a .csv instead of a .xlsx?

I changed one of the newbies ActiveX toolkits provided by Joe_H to enter a number in a spreadsheet by using the following code 'save to existing Spreadsheet.vi. However, since it was designed for a .xlsx, it uses an entry for the index of the sheet (that I set to 1 when you use my .csv file). Currently, the program works, but I was wondering if there is a way to remove the index sheet part. I tried to just delete, but I could not find how connections for refnums etc. should then work out. Thanks for any advice, even if it's just to say that nothing major should be done.

I don't think that there is a much easier way to do what you want then the code you provided.

How to condigure guest OS when you use net mode bridged when connecting by local security-enabled wireless network

I am running VMWare workstation on a host with the guest OS Windows XP and ubuntu.
I work in a place where we have a LAN wireless - security-enabled.
When you use the NAT configuration - my OS comments doesnot seem to be able to run and use the DNS and the Windows network AD features.
-I want to set up the guest operating system to connect to the network using the bridged mode.
Unfortunately - the 'visible' for Windows XP network connection is reported as a wired lan connection. This means that I am not able to configure options for the connection wireless security.
Is there a configuration missing that I forgot, I have to do on my wirtual machine, toolsthat host or vmware would allow this Setup program begin work?
Plese - if anyone has som einput it would be greatly appreciated.
Best regards
Poul Christiansen

Wireless configs should be set to the host OS, unless the wireless usb is attached directly to comments.

For mode bridged you have, connect to the guest is actually nothing else that a wired connection and XP won't be able to use it as wireless (except usb of course).

This means that your association and authentication to the AP will have on the host operating system linux tools.

Insertion and extraction of data from a database by USING SQL Developer al32UTF8
Hi guys,.

Before I post my questions, I think it's better for me to give you guys my first understandings so that it is easier to understand where / if I have gone wrong...

I use Windows XP and Oracle 10 g
------------------------------------------------------------------------------------------------------------------------------------------------------------------

Non-unicode client - a client program that needs to use the code page of the operating system for the mapping of unicode data retrieved from the database as well as the support to display/insert characters from the code page to the database.
For example sqlplusw.exe

Therefore, when you use a non-unicode client

(1) we define the code page of the OS (Control Panel - regional and language of the parameter - advance - the language for non-unicode programs) to the code page that contain the characters that we will view/insert.

(2) we also defined the NLS_LANG characterset on the character set of code page, that we'll insert so that when we do an insert (for example in thai), oracle will and automatic conversion to Unicode can take place. This is also true when recover us the database unicode data so that the correct character set conversion can take place.

INSERTION OF
THAI->-> UNICODE conversion

RECOVERY OF
THAI <-conversion <-UNICODE

I hope that my basic understanding is correct up to this point.
---------------------------------------------------------------------------------------------------------------

Unicode client - a client program that supports display/inserting unicode characters without the need to set the code page of the operating system (Control Panel - regional and language setting - control - language for non-unicode programs advance)
For example isqlplus http or SQL Developer

However,.

(1) there are still set the NLS_LANG so that the correct conversion can take place between the client and the database.
For example, when the recovery if we set NLS_LANG value ZHS16GBK (Chinese) character and store data in Unicode in the database is for example (THAI), then the conversion would be a mistake.
It's a supported unicode client, then the NLS_LANG character set should be set to UNICODE as well.

---------------------------------------------------------------------------------------------------------------------------

Those are my questions
* Important - please help if you're busy and don't have the time to answer the remaining questions

(* Q1) if I had to use a unicode client, what should I put my character NLS_LANG set?
AMERICAN_AMERICA. UTF8?

(* T2) where can I put the NLS_LANG information of character in SQL Developer, I know there is a metalink for setting NLS_LANG using isqlplus but I cant seem to google each led for SQL developer.

Q3) is my basic understanding of up to this point? If no, please explain in a term more widespread that I'm really not familiar with character sets code page, unicode and fonts, glyphs...

A unicode client (Q4) didn't need to refer to the OS codepage (regional and language updates), y at - it a code page UNICODE for the customer to refer to, or is there an available window API?

Q5)

, there are still set the NLS_LANG so that the correct conversion can take place between the customer and the > > database.
For example, when recovery if we set NLS_LANG value ZHS16GBK (Chinese) character and the data store in > > unicode in the database is for example (THAI), then the conversion would be erroneous.

I'm just on this point for customer UNICODE supported?
--------------------------------------------------------------------------------------------------------------------------

Thank you for spending the time to read my questions and I hope to hear soon tips from you guys.
Million thanks again for sharing.

Best regards
Noob, but eager to learn
The requirement to always set NLS_LANG is not true for JDBC, which ignores the NLS_LANG altogether. Java programs extract the textual data in string variables, which uses Unicode UTF-16 by design. JDBC defines the conversion of character sets so that data is converted between UTF - 16 and the database or the national character set.

The obligation to set NLS_LANG is not generally true for the OIC, either. The first call to a problem of the BEAK may be OCIEnvNlsCreate(). This call has two parameters that allow the caller to set the character set to use for the text of VARCHAR2/TANK/LONG/CLOB/statement and the character set to be used for NCHAR/NVARCHAR2/NCLOB. Only if these character sets is specified as 0, character set NLS_LANG is used. Also, the OIC programs can specify different character for each binding sets or set the variable (i.e. the buffer input/output). Note: The OIC programs always use NLS_LANG to initialize the language settings and the territory for the client program and the database session. Only the character set can be specified is OCIEnvNlsCreate().

OCIEnvNlsCreate() can specify the client character set to UTF-16 (platform boutien) format. This is not possible with NLS_LANG.

Various interfaces based on the BEAK, such as ODBC Oracle and .NET for the ODP, explicitly initialize OCI with character set Unicode and therefore ignore the NLS_LANG character set as well.

Thnx,
Sergiusz

Why Oracle ManagedDataAccess (4.121.1.0) throws a System.FormatException "first chance" exception to the debugger when you use OracleCommand.BindByName (on some machines, but not others)?

This occurs when calling a ref cursor-returning packaged function stored with OracleCommand.BindByName set to true.

When BindByName undefined, it works as expected.

I've only been able to recreate this problem on a machine in my control. This issue has also reported to me by a customer.

I tried to change the locale of the system of EN - UK EN-US, but I was not aware of any change in behavior.

Similarly, I've tried explicitly overriding the default locale of the system with the OracleGlobalization parameters, and it also had no effect.

Thanks a lot to qualify again for me Alex. I'll try upgrading to the latest version of the provider.

The difference in behavior between the two hosts was found to be reduced to differences in configuration VS.

Checking 'Just my code' prevents the first chance thrown in the debugger exception. As in fact, the exception is handled in the provider, it is enough for me.
