Hi All,
after searching lot on SDN, i found out that OLE concepts can not be used in WD ABAP environment. Please let me know if i am correct or not.
as of now, i am building the excel and using below method to create it.
*Create the Excel File
cl_wd_runtime_services=>attach_file_to_response(
i_filename = lv_filename
i_content = lv_xstring
i_mime_type = 'application/msexcel'
i_in_new_window = abap_false
i_inplace = abap_false ).
The problem in above method is that, i can not format the excel as i wanted. for e.g. i wanted to put values in particular cell, make it BOLD, italic etc.
Is there any way to achive this? Please let me know.
Thanks,
Chandra

File -> Export
This User Tip
https://discussions.apple.com/docs/DOC-4921
has details of the options in the Export dialogue.
Move the Library?
Make sure the drive is formatted Mac OS Extended (Journaled)
1. Quit iPhoto
2. Copy the iPhoto Library from your Pictures Folder to the External Disk.
3. Hold down the option (or alt) key while launching iPhoto. From the resulting menu select 'Choose Library' and navigate to the new location. From that point on this will be the default location of your library.
4. Test the library and when you're sure all is well, trash the one on your internal HD to free up space.

How to convert BLOB data into string format.
Hi,
I have problem while converting blob data into string format.
for example,
Select dbms_lob.substr(c.shape.Get_wkb(),4000,1) from geotable c
will get me the first 4000 byte of BLOB .
When i using SQL as i did above,the max length is 4000, but i can get 32K using plsql as below:
declare
my_var CLOB;
BEGIN
for x in (Select X from T)
loop
my_var:=dbms_lob.substr(x.X,32767,1)
end loop
return my_var;
I comfortably convert 32k BLOB field to string.
My problem is how to convert blob to varchar having size more than 32K.
Please help me to resolve this,
Thanx in advance for the support,
NileshNilesh,
. . . .The result of get_wkb() will not be human readable (all values are encoded into some binary format).
SELECT utl_raw.cast_to_varchar2(tbl.geometry.get_wkt()) from FeatureTable tbl;
-- resulting string:
☺AW(⌂özßHAA
Å\(÷. . . .You may also want to have a look at { dbms_lob | http://download.oracle.com/docs/cd/B19306_01/appdev.102/b14258/d_lob.htm#i1015792 } "The DBMS_LOB package provides subprograms to operate on BLOBs, CLOBs, NCLOBs, BFILEs, and temporary LOBs."

How to Get Blob data(In String Form) using OCCI
Hello frnds,
I am new to OCCI,so i hvnt that much of master in that side.
I have one problem while handling BLOb data.
How to convert binary form of SDO_GEOMETRY data into string format. I am able to convert data by using PLSQL block,but its take so much time to execute.So performance is the main issue.So if there is any API in OCCI which convert directly blob data into string format.
Thanx in advance for your support,
Nilesh.Have you tried reading "http://download.oracle.com/docs/cd/B28359_01/appdev.111/b28390/lobs.htm#BABDEGJD" ? This explains how you can read from BLOBs into a C vector (or C++ vector of chars).

How to Restrict Master data in value help screen for a user???URGENT
Hello Gurus,
I have a requirement.When a authorized user logins to view the report, he should see only list of customers assigned to that user in the value help screen, instead of displaying whole master data.and the data is displayed perfectly fine for the authorized sales rep. By default, Value help screen displaying all the customer numbers.
How can I restrict in the value help screen?
Any help appreciated with points.
Regards,
PNKHi Chandran,
I got that Idea too. I created a authorized customer, I created a authorized Object and assigned to a role.But in the role, when I am changing the object to generate profile, it is asking to select list of customers from the customer table.If the customers are always constant then this would work, but in my scenario, customers for the sales rep changes over time and when I ever reps open the query, they should see updated list of customers assigned to them only, as we update the master data everyday from source system and that shud reflect in the value help.
I am trying User Exit to achieve this, but I am not getting proper ideas how to do this.
Any Help on this issue with user exit code???
Thanks in Advance

Thanks
Edited by: prakash on Feb 5, 2012 11:41 PMPost the 4 digit Oracle version.
Did you read the Doc for DBMS_LOB.CONVERTTOCLOB? - http://docs.oracle.com/cd/B28359_01/appdev.111/b28419/d_lob.htm
The function can convert data from one character set to another. If the source data uses a different character set than the target you need to provide the character set id of the source data.
The blob_csid parameter is where you would provide the value for the source character set.
If the source and target use the same character set then just pass zero. Your code is passing a one.
>
General Notes
You must specify the character set of the source data in the blob_csid parameter. You can pass a zero value for blob_csid. When you do so, the database assumes that the BLOB contains character data in the same character set as the destination CLOB.
>
Same for 'lang_context' - your code is using 1; just use 0. It is an IN OUT
>
lang_context
(IN) Language context, such as shift status, for the current conversion.
(OUT) The language context at the time when the current conversion is done.
This information is returned so you can use it for subsequent conversions without losing or misinterpreting any source data. For the very first conversion, or if do not care, use the default value of zero. -
How to Scramble BLOB data stored in Tables
I have received a directive from the top management, in their drive to comply with security standards, that BLOB data stored in the database ( e.g., Word, Excel, PDF, .... documents) needs to be scrambled in DEV environment.
I have written up a routine which will scramble CHAR/VARCHAR/NUMBER, as this sounded more logical to me.
But, have come to a stand-still in figuring out how to scramble binary data??????
Is this at all possible? To me, it sounds impossible, but I'm open to ideas.
Has anyone out there thought up of a solution to this?
If so, please do advice.
Eager to know.Hello Dave & BluShadow,
Thanks for your responses.
So, 10g is the answer huh.... That's not going to make people jump with joy, at least they'll hold off on this for now. My other possible alternative, is to have one dummy BLOB each of Word Doc, Excel, PDF, ... and overwrite each actual file attachment with the dummy. I know... I know.. not the best.
Regarding the management stuff... Hmm... This entire thing comes up because of the policy of refreshing the DEV / TEST environments with the actual production data. They've been doing this for a long long time.... The Good side to this is that they've taken the step in the right direction on this one, though I wish it would have been to totally avoid doing this kind of a refresh and use test data.
Thanks again. Do let me know if there's anyother alternative too. -
How to put the data from one excel sheet in another excel sheet
hi ,
I want put the data from one excel sheet in another excel sheet in seq. order Eg: I have one excel sheet in which i have 3 col. Name , Sno. , Email along with data .I want to put data from this sheet to another excel sheet in the following orders of col. Sno,Name, Email .
While loading data in another sheet , i have to perform validation like char field should n't contain numeric values and vice versa .
Let me know on this soon ..
regards
PrashantWell, you can issue separate queries with the ordering you need from each tab in the spreadhseet. You can open an ODBC connection from a VBA macro, select a sheet, run a query, select another sheet and run another query. As for the validation, you can do this in Oracle via stored procedures or again in VBA code.

How to compare BLOB data in 9i between 2 tables
Hi
I need to compare data between two tables (which are the same structure across two schemas) which has BLOB data.
I am using 9i so cannot use some of the new functionality provided in 10g and 11g.
I was hoping I could, rather primatively, use the dbms_utility.get_hash_value function and compare has values.
Running this works:
select
dbms_utility.get_hash_value( to_char('1'), 0, 1073741824 )
from dual
DBMS_UTILITY.GET_HASH_VALUE(TO
201884475but this doesn't:
select
dbms_utility.get_hash_value( to_blob('1'), 0, 1073741824 )
from dual
ORA-06553: PLS-306: wrong number or types of arguments in call to 'GET_HASH_VALUE'Is there anyway to manage this?
