Column Datatype Change

Hi,
I created a table with some 10 columns earlier, now one of the column datatype needs to be changed to varchar2(2), which actually in the database it is number.
The thing the table now contains 10 records. Its not allowing me to modify the column datatype, because it has rows in it. How to change the column datatype with data in the table. Pl reply ASAP.
Thanks

See the following example.
Let's modify deptno column from number to varchar2 :
SCOTT@demo102> desc emp2

Image manipulation and keeping its size same

Hi
I am working on an iPad application which allow user to redact portion of an image. Currently i have added UIView to my imageView and draw brush path using UIBezierPath and save the image by taking snapshot of my Uiimageview. Everythings working fine except the image size, suppose my image is of 1.5 Mb then after saving an image it reduces to 0.5Mb.
My requirement is that after saving image my image size should not reduce.
if (UIGraphicsBeginImageContextWithOptions != NULL) {
            UIGraphicsBeginImageContextWithOptions(self.imageVw.bounds.size, NO , 0.0);
            [self.imageVw.layer renderInContext:UIGraphicsGetCurrentContext()];
            viewImage = UIGraphicsGetImageFromCurrentImageContext();
            UIGraphicsEndImageContext();
This is what i am using to save an image.
Is there any other way to manipulate image without losing its size. For example reading image pixels and writing and replacing new pixels to it?
Looking for your answer.
Thanks.

Any help would be appreciated...

I have a large PDF that I cannot send via email because of its size, 76 MB. How do I shrink this file or convert it to another format so I can email this, less than 20MB? Thanks for your help

Open the file in Preview and select "Save as..." from the File menu. Select "Reduce File Size" from the Quartz Filter menu and save. The size probably won't be reduced enough, though. You may have to split the file into several parts and mail them separately. Or upload it to a web server and send the link.

All of a sudden, the "save" page occupies all of my screen and I can't find a way to reduce its size -- this never happened before -- very inconvenient

When I click on "save" the resulting dialogue box fills the entire screen. I'm unable to reduce its size by using the mouse to pull in the borders of the dialogue box, and I can't find any other way to reduce it. This problem appeared spontaneously. It didn't start immediately after installing a new plug-in or a new Firefox release -- it just happened one day. I've used Firefox for years and never had this very inconvenient problem before.

Is it the dialog that appears for Save Page As? Like other windows, it could be maximized/restored by double-clicking the title bar. Does that make any difference?
If not, it might be necessary to rename or delete the localstore.rdf file, which stores window positions and related settings...

OBIEE - changing imported column datatypes

Hi All,
I am trying to join 2 tables in physical layer but the columns on which I am making join condition have different datatypes defined(one is datetime,another is timestamp).Hence, I am getting error incompatible datatypes can't be joined.
I don't want to change the columns datatypes in ohysical layer bcz I am not sure if some other report using this rpd might be using the join conditions based on existing datatypes.Is there any alternative to this?
Please suggest.
Thanks,
Neha

Please try to use this function. it is good if we have sample data for both columns.Please provide if you have issues using following function
Evaluate( 'to_date(%1,%2)',Evaluate( 'TO_CHAR(%1)' as char,20090101) , 'yyyymmdd')
Thanks

Retrieve column names of a table!!

Hi all,
I want to retrieve column names of a table 'test' whose values are null
For ex:
select * from test
will give the results as
column_1 column_2 column_3 column_4
111
lets consider the case that the table has only one record.
accordingly we have to get column_2 ,column_3 and column_4 as the result.
i tried dynamic 'execute immediate' statement and tried to extract in one single execute immediate statement but i was not able to accomplish because of the multiple columns.
is it possible without using a pl/sql function or procedure??

Check this:
SQL> INSERT INTO my_Test values('ABCD',NULL,NULL);
1 row created.
SQL> COMMIT;
Commit complete.
SQL> select * from my_Test;
COL1       C COL3
ABCD
SQL> declare
2 CURSOR C1 IS SELECT column_name FROM all_tab_cols WHERE table_name = 'MY_TEST';
3 v_sql VARCHAR2(10000) := NULL;
4 my_null_col_list VARCHAR2(32767) := NULL;
5 my_cnt NUMBER := 0;
6 BEGIN
7 FOR I in C1 LOOP
8 v_sql := 'SELECT COUNT(*) FROM my_test WHERE '||I.column_name ||' IS NULL';
9 execute immediate v_sql INTO my_cnt;
10 IF (my_cnt > 0) THEN
11 my_null_col_list := my_null_Col_list||','||I.column_name;
12 END IF;
13 END LOOP;
14 my_null_col_list := SUBSTR(my_null_col_list,2);
15 dbms_output.put_line('Columns that have null values for table my_Test are:'||my_null_col_list);
16 END;
17 /
Columns that have null values for table my_Test are:COL2,COL3

Suppress Overall result (both rows and columns side and its data)

Hello all,
I need to do some settings in BEx Query Designer, so that In BEx Analyzer, I don't see 'overall result' both on 'rows' and 'column' sides
This is what I have done so far
In 'rows' section, Properties of my KF (no. Products) then 'calculation' tab 'calculate result as'=Suppress result
This way in BEx Analyzer I don't see the FIGURES/DATA for 'Result' and 'overall result' BUT 'result' and 'overall result' still exist both on rows and colum side even if there are not figures in them.
Is there any property in BEx Designer so that I don't see 'overall result' at all
Best regards
Ahmad

thanks for responding
selecting a characteristic, properties, Display tab, Result lines: Always Suppress
with this I don't see 'result'
but 'overall result' result exist both on 'rows' and 'column' side alongwith its data.
If I combine the above with this: selecting KF, properties, calucations, Calculate result as: Suppress result
then
I don't see the data in 'overall result' BUT 'overall result' still exist both on rows and column sides
any setting so that 'overall result' completely vanishes
Best regards
Ahsan

Error: unable to retrieve column information from the data source

Hi,
I am trying to set up a data flow task. The source is "SQL Command" which is
a stored procedure. The proc has a few temp tables that it outputs the final
resultset from. When I hit preview in the ole db source editor, I see the
right output. When I select the "Columns" tab on the right, the "Available
External Column List" is empty. Why don't the column names appear? What is
the work around to get the column mappings to work b/w source and
destination in this scenario.
In DTS previously, you could "fool" the package by first compiling the
stored procedure with hardcoded column names and dummy values, creating and
saving the package and finally changing the procedure back to the actual
output. As long as the columns remained the same, all would work.
Thats not working for me in SSIS.
Thanks in advance.
Asim.

I had a similar problem retrieving column information when calling a stored procedure which returned a table declared as a variable within the procedure. I used "Command SQL" as data access within the OLE DB Source Editor, and "exec <sproc_name> <param_list>" as text for the SQL command.
After a few trials and errors, I noticed when I removed the IF statement that validated the parameter passed to the sproc it worked, i.e. SSIS could retrieve the column information, otherwise it wouldn't. Is it because of the IF, the BEGIN/END, or the RETURN? I do not know as I did not test further, but by removing the entire instruction block pasted below, it worked. Hope that it helps.

Why did rebuilding my Aperture library increase its size by 50 GB?

After updating to 3.3, library conversion was no problem, but I rebuilt the library today and its size increased from 125 GB to 173 GB. This is large enough to be discomforting. All masters (orginals, I guess, now) are referenced.

I have maintain previews off. For ones that I need (like to share with iPhone, Flickr, etc.), I generate them manually. I might try deleting all previews and see what happens to the library size.
I rebuilt because vault updates (for both exisiting and new vaults) were hanging.

On certain sites, some lines have the lower half missing. Changing the font or its size does not help. The error does not appear with Iceape or Chromium.

On some sites certain lines appear with the bottom half missing, as if obliterated. Changing the font or its size does not help. The error does not appear with Iceape or Chromium.

I looks that the whole line doesn't fit in the container, so the bottom part is cut off. The usual cause is that a font is used that takes more vertical space, so any increase or changes from the font in what the website prescribes can cause this issue. I've seen web pages that were even affected by changing the minimum font size from none to 1 (!). If you do not have the font installed that the website specifies then Firefox will fallback to another (default) font that may have different dimensions.

I'm using iphone 5 but its camera is not properly working. all the images i'm clicking are of dimension 600X800 and the size of the image is just 60-70 kb. now please tell me how to increase the dimension of images and its size.

i try to keep my thumb palms off the mouse pad when i am typing but every now and then my screen resizes larger or smaller until i take my left palm off the keyboard base its only when my left palm is resting on the base next to the touch pad. i type pretty fast so it gets annoying and yes it also jumps screens or reverts back to previous message and i have to choose ctrl z to undo and get back to my message i was typing... it also switches tabs on me as well... not sure why my palm being on the left of the keypad on the base should effect anything but it does after a while. and i have to stop what i am doing...and go to the firefox menu and change the screen size back down to 100% sometimes it goes up to 200-300 other times it goes down to 70-80% i find it annoying i i wish there was a way to turn off the screen resize in the setup panel. if its just left to be 100% i am happy with that... i don't need it to be bigger or smaller... there should be a way to LOCK it down... i understand that there are people out there with eye problems and needs to have the screen size increase using the + or - but there should be a lock so it just stays no matter what is happening on my keypad or touch pad or base of the pad... that screen size will not increase or decrease. unless i turn off the lock... perhaps this is something they can implement in the next version or do a quick update of the browser
