Tablespace encryption or column based?
Oracle 11.0.1.7:
In Advanced Security Tutorial it doesn't say if tablespace encryption is better or column based encryption is better in terms of performance. I did hear from my peers that tablespace encryption is faster but that logic seems to be so much flawed because encrypting everything should have more overhead. Does anyone have some kind of stats on which is better over other?
When you do column-level encryption, there are [various restrictions|http://download.oracle.com/docs/cd/B28359_01/network.111/b28530/asotrans.htm#ASOAG9518] you need to be aware of. Among them, is that index range scans are disallowed. If your application depends on index range scans, as opposed to other types of index accesses, on a column you are encrypting, that may dwarf the performance impact of the actual encryption.
I'm assuming your 5% figure comes from [this discussion on performance overheads of TDE|http://download.oracle.com/docs/cd/B28359_01/network.111/b28530/asotrans.htm#ASOAG9550]. If that is the case, yes, if you have a SELECT statement that selects two columns that are both encrypted at the column level, the performance overhead is probably relatively linear.
Tom Kyte's [All About Encryption presentation|http://www.ooug.org/presentations.html] and the associated scripts are probably a good place to start quantifying the performance overheads.

Encryption the column in oracle 10g
Hi,
I have a table containing ~ 45 millions records.
I have to apply encryption to 37 columns in the table. I tried with one column, that took around 7.5 hrs. to complete.
I used the below command for encryption:
ALTER TABLE employee MODIFY (first_name ENCRYPT NO SALT);
Could you please suggest some alternative way to apply the encryption to this table.
Thanks in Advance!!
Regards,
Ashwani N.Hi Ashwani,
my 1 CPU 1 GB RAM laptop encrypts 1,000,000 credit card numbers in 90 seconds; so your's should done in an hour but not more.
You can use Online Table Redefinition, but then, with 37 columns encrypted, your performance impact will be significant once you're done.
I would highly (!!) recommend to upgrade to 11gR2 and use TDE tablespace encryption.
HTH, Peter -
Can I get multiple sums in a single column based on a "code" I place.
After importing a file of check/debit card activity from my bank, can I 'code' the line items based on tax categories ie Utilities, Medical expenses, Auto expenses, etc. and then get sums for each based on that code I placed in a single column? That would mean multiple sums in a single column based on the code used for each tax related expense. For instance, I would put UT in the column for utilities expenses and MED in the same column if it were a medical expense. I would then want the sum for all items in that column for each item code. Is this possible or do I need to use a different approach to get this information.
My guess is that the SUMIF function may be your friend.
It's well described in the *iWork Formulas and Functions User Guid*e which every user may download from the Help menu.

View with columns based on function - problem with query
Hi,
I'm using Oracle 9i;
I've created a view which has columns based on a table columns (multiple columns from 1 table) and funtion (multiple columns based on 1 function).
The function takes ID as the first argument and name of the column to determine which value to return as the second one.
Here is a sample of such function (simplified):
FUNCTION my_function
(in_id IN NUMBER, in_col_name IN VARCHAR2)
RETURN VARCHAR2
IS
c_name VARCHAR2(100);
c_last_name VARCHAR2(100);
BEGIN
SELECT T.NAME, T.LAST_NAME
INTO c_name, c_last_name
FROM TABLE_1 T, TABLE_2 Z
WHERE T.PK = Z.FK
AND Z.ID = in_id;
IF in_col_name = 'NAME' THEN
RETURN c_name;
ELSIF in_col_name = 'LAST_NAME' THEN
RETURN c_last_name;
END IF;
END;
For simplicty I've restricted the number of columns.
CREATE OR REPLACE VIEW my_view
(ID, NAME, LAST_NAME)
AS
SELECT
T.ID ID
,CAST(my_function(T.ID,'NAME') AS VARCHAR2(100)) NAME
,CAST(my_function(T.ID,'LAST_NAME') AS VARCHAR2(100)) LAST_NAME
FROM TABLE T;
There is no problem with query:
SELECT * FROM my_view;
The problem arises when I query the view (regardles of '=' or 'LIKE'):
SELECT * FROM my_view
WHERE name LIKE '%some_part_of_name%'
The query returns rows for same names, for same it doesn't. If I put '=' and the whole name the query returns nothing, but when I put 'LIKE' and the first letter it returns rows in some cases.
I've tried to debug this situation and I've discovered that the function recives ID not in the proper order and not the same amount of times - in explicit:
for each ID in (1, 2, 3, 4, 5, 6, ... , 100) the function should be called twice for each ID and in the same order, but it does not.
I get 1, 1, 2, 3, 3, 6, 20, 20 and so on.
Help needed.
Greetings.The problem is more complicated than the solutions provided here.
The reason why I'm using the function is this:
the original view was constructed using multiple union all selects and the speed was terrible. I've created the index on the base table to obtain a proper sort. For retriving all records at once the view works perfectly, but if one wants to query by columns based on function the results are suprisng - sometimes there are, some times there are none, or if you serch with "like" and only a part of string there are results, but with "=" there are no results.

Hide or show a column based on a parameter?
I have a parameter that has two values linked to 2 fields and included in my SQL query. I would like to hide or show columns based on the parameter value chosen for other fields. How do I begin to write the expression?
Hi KittyCat101,
Based on my understanding, you want to display columns dynamically based on a parameter, right?
In your scenario, you can specify column visibility for all columns based on the expression which contains selected parameter values. So that if we select a value from the drop-down list of the parameter, the column will display based on the column visibility
expression. For more information, please refer to this article:
Conditionally Setting Column Visibility in SSRS.
If you have any question, please feel free to ask.
Best regards,

How to insert into date column based on other columns?
Hi
I have four columns in a table called game named as

Create a derived column based on a value within the file name
I am importing a CSV file which is easy enough, but I have an issue where I need to manufacture a couple of column values based on the filename of the input. So this same process will import different types of records to the same table in sql server.
I need to pull out the record code from the file name.
For instance, say I can use the same package to input two different CSV files. One is named Input_M02_Data.csv and one named Input_B15_Data.csv. I need to create a derrived column and store the record code there (i.e.: M02 or B15) based
on which file it came out of.
fyi-
I also need to create a second column for Dept based off of the file name as well. M02 is dept 45 and B15 is dept 99 which I also need to insert into this table when I import the data from the .csv file.
Any help is greatly appreciated!Hi Jason,
According to your description, you want to add two derived columns based on the file name to also insert into table. One stores the value between two “_” within file name, another stores the department based on that column.
If in this scenario, we can add a variable FileName that stores the filename, then add the two variables as derived columns like below in the Derived Column Transformation:
Name:
SUBSTRING(@[User::FileName],FINDSTRING(@[User::FileName],"_",1)+1,FINDSTRING(@[User::FileName],"_",2)-(FINDSTRING(@[User::FileName],"_",1)+1))
Dept:
@[User::Name] =="M02"?"dept 45":@[User::Name] =="B15"?"dept 99":"dept 00"
The following screenshot is for your reference:

When I import a text file(comma separated) into a numbers spreadsheet all the data goes into one column instead of individual columns based on the comma separators. Excel allows you to do this during the import.. Is there a way to accomplish this in numbers without opening it in Excel and the importing into Numbers.
Your user info says iPad. This is the OS X Numbers forum. Assuming you are using OS X… Be sure the file is named with a .csv suffix.
(I don't have an iPad, so I don't know the iOS answer.) -
Virtual column based partitioning
Hi,
we have a non-partitioned table in a production database and wish to partition it based on an expression. Since we are on 11.2 the first thing that comes to mind is virtual column based partitioning. The "problem" is that in order to partition by a virtual column, you have to create one, and adding a new column to a table could break any application that doesn't reference the existing columns by name, e.g. "SELECT *" or. "INSERT INTO table VALUES(....)".
My question is: is it possible to somehow specify the expression on which to partition directly in the "partition by" clause rather than specifying it as a virtual column definition?
Example:
Instead of this..
SQL> create table test (
2 id number not null,
3 content varchar2(10),
4 record_type varchar2(1) generated always as (case when (substr(content, 1, 1)='B' and not substr(content, 1, 3)='Bxy') then 'B' else 'A' end) virtual
5 )
6 partition by list(record_type)
7 (
8 partition partA values ('A'),
9 partition partB values ('B')
10 );
Table created...I'd like to use something like this:
SQL> create table test (
2 id number not null,
3 content varchar2(10)
4 )
5 partition by list((case when (substr(content, 1, 1)='B' and not substr(content, 1, 3)='Bxy') then 'B' else 'A' end))
6 (
7 partition partA values ('A'),
8 partition partB values ('B')
9 );
partition by list((case when (substr(content, 1, 1)='B' and not substr(content, 1, 3)='Bxy') then 'B' else 'A' end))
ERROR at line 5:
ORA-00904: : invalid identifierThank you in advance for any answers.

Jureadding a new column to a table could break any application that doesn't reference the existing columns by name, e.g. "SELECT *" or. "INSERT INTO table VALUES(....)". "Ok, i got it. You mean, in application you are using select * from yourtable; and those data is being used by a datagrid or any control, then where that application will show / handle the new column data right ?
Yes, thats why DBA and developers do SDLC (Software Development Life Cycle); that our table will be looks like this, these will be columns, these will be their data types, these will be followed in naming convention, privileges, indexes, storage parameters, constraints, dependent objects etc. Now after creating the table, you found a need to add a column, it means there was some lapses happened at the design time/phase or business requirements are newly defined.
So, as far as concerned of select * ... ; you have to change in the application by :
select col1, col2, new_col from your table... (as per order of your datagrid control columns). There is no other solution, you have to change in application code at every place where you have used select * and if those statements are being merged / deals into a control)
New column addition will hamper only at select * from... not with any INSERT/UPDATE/DELETE, because if they are running fine it means, they have well written column references. For DMLs you need not worry so far.
By the way, what is your technology for application ? I have worked on couple of applications in ASP.NET with using datagrid which auto add/removes the columns in itself as per cursor result (not rememberring the exact property of it though)

Changing display of item in column based on its value
Hi,
I'm confused as to how I can change the display attributes of an item in a column based on that items value. I've grepped through the forums and it seems there are ways to do this in the report query but that seems inefficient. My preferred method would be at the column level, I could set up some logic that says "if the value is X then display A and if the value is Y then display B". In this case A and B could be a snippet of HTML to display an image that represents the value.
Seems reasonable that this app would have this functionality and I'm sure it's there, I just can't seem to find it.
Help! Suggestions welcome, heckling encouraged!
Thanks,
JonJon,
You should probably start storing the images in a custom table as described here:
http://www.oracle.com/technology/obe/apex/apex31nf/apex31blob.htm
The following column is taken from the Products query in the sample application (page 3):
decode(nvl(dbms_lob.getlength(p.product_image),0),0,null,'<img src="'||apex_util.get_blob_file_src('P6_PRODUCT_IMAGE',p.product_id)||'" height="75" width="75" />') img
Note, getting this configured is a little tricky the first time. Notice that there is an item from page 6 referenced. Page 6 contains that item and a DML process both of which are needed for everything to work. Read more here:

NehaYou can also use CalcFields to bind to your data if you don't want the Icon column to be part of you model.
Documentation/AdvancedTopics/DataBinding/CalcFields – SAPUI5 Wiki (TIP CORE User Interface)
I've modified Dennis' example slightly to use a CalcField, notice the paths are defined to create a composite binding, the data is the automatically passed to the formatter function.

Dispaly or Hide a column based on Prompt Value
Hi All,
How can I Display or Hide a Column based on Prompt Value selected?
On my dashboard I have a Report/Request and a Dashboard Prompt.
Dashboard Prompt has three values, say: *'A', 'B' and 'C'*.
And my report/request has three columns named *'Field1', 'Field2'* and Field3'.
What I am trying to achieve is that whenever user selects prompt values as *'A' or 'B'* all the three fields on my report named *'Field1', 'Field2' and Field3'* should be displayed, however whenever user selects prompt values as *'C'* only fields named *'Field1' and 'Field2'* should be displayed.
Thanks,
DeepakHi Bhavna,
I tried using View Selector, however I am not able to achieve the required functionality with that.
I created a Request with 3 columns in it, then I switched to criteria and added another table to that. The new table automatically got the similar 3 columns used in the first report. Now when I tried to delete one of those columns from the new report, it also got deleted from the first report.
All the views are dependent, changes made to one are reflected in other.
Can't figure it out, where am I going wrong?
Thanks,

ChakriHi Chakri,
Your setting the table value that time you will get the Country Code.
1.Create the attribute like Country_Column_Visible Data Type bind the com.sap.ide.webdynpro.uielementdefinitions.Visibility this value you need to bind the table country column.
2.In Table You need to check the country code Japan is available you need follow this below sample code.
for(int i=0;i<tablesize;i++)
tablesithValue=wdContext.nodeTable().getTablenode(i);
if(null != tablesithValue.getcountrycode)
if(tablesithValue.getcountrycode.equalsIgnoreCase("Japan"))
wdContext.currentxxxxElement.setCountry_Column_Visible(WDVisibility.NONE);
}else
wdContext.currentxxxxElement.setCountry_Column_Visible(WDVisibility.VISIBLE);
Use the above code you condition it will work.I hope it will help you.
