Need help in creating a view with Encryption for hiding the code used by the multiple users

Hi,
Can anyone help me out in creating view with encryption data to hide the stored procedure logic with other users.
I have create a stored procedure with encryted view but while running this manually temporary views are getting created, therefore the problem is if there are 500 entries then 500 temp views will get created.
Any solution to aviod creating temporary views, please refer my code below
USE [etl_validation]
GO
/****** Object: StoredProcedure [dbo].[Pr_DBAccess_mod]    Script Date: 05/23/2014 12:53:22 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
ALTER PROCEDURE [dbo].[Pr_DBAccess_mod](@ETL_CONFIG_ID INT)
AS
BEGIN
DECLARE @openquery NVARCHAR(MAX),
@DATABASENAME NVARCHAR(100),
@HIERNAME NVARCHAR(100),
@TABLENAME NVARCHAR(100),
@SERVERTYPE NVARCHAR(100),
@SERVERNAME NVARCHAR(100),
@USERNAME NVARCHAR(100),
@PASSWORD NVARCHAR(100),

SELECT @openquery
END
EXECUTE sp_executesql @openquery
END

Hi aa_rif,
According to your description and code message, you execute the sp_executesql statement in your stored procedure, it indeed create many views with a tablename and ETL_CONFIG_ID named. If you need not to use these temporary views, you can delete them when
it contains the tablename in one view name.
In addition, if you want to create view with encryption in SQL Server, you can use directly the ENCRYPTION option to encrypt the T-SQL of a view in create view commands, for more information, see:
http://learnsqlserver.in/4/Create-View-With-Encryption.aspx. if not, you can descript more detail about requriements, so that more forum members can involve into the thread and help you
out.

On the AGO Function need to Create TODATE function with Diff levels - MTD,Q

Hi All,
My Basic Requirement is to Create Time Series Function on AAA ie ( Month To Date , Quarter To Date and Year To Date )
The Logic for the AAA = XXX / Previous 3 Months Revenue.
we know that we can use the AGO Function to create Previous 3 months Revenue with Month is Level . But the issue is .... i cant use AGO function since i need to perform Year to Date, QTD and MTD upon 'AAA' this OBIEE doesn't permit to use nested time series functions upon varying levels .
So How can i Resolve the issue ie creation of TODATE function on the AGO Function with Diff levels
Thanks,
Swapna S

hi,
for your requirement create three repository variables like
for previous 3 months create repository variable like
select to_char(sysdate,'yyyymm') -3 from dual;
for month to date first calculate first day of the month
select To_Char(Add_Months(Last_Day(Sysdate),-1) + 1,'MM/DD/YYYY') from dual;
after put a filter in answers date between first date of the present month and current date
create the same thing for year to date
calculate first date in the year like following query
select To_Char(Trunc(Sysdate,'YEAR'),'MM/DD/YYYY') from dual;
after that apply filter date b/w first date in the year and current date
i hope it works for your scenario

your problem is , that execute immediate does't recognize ffdt
You have to concatenate literals
create or replace procedure asho2005.mock_pro( fin_fr_dt in date, fin_to_dt in date) is
ffdt date;
ftdt date;
begin
select to_date(fin_fr_dt,'dd-mm-yyyy') into ffdt from dual;
select to_date(fin_to_dt,'dd-mm-yyyy') into ftdt from dual;
execute immediate 'create or replace view mock_vu as select a.amt from cbtran a where chq_dt > '''||ffdt||''' and chq_dt <'''||ftd||'''';
end; BTW, your view doesn't return any rows
ffdt and < ffdt :-)
Besides that , it's a very very bad method!
You must not create views in runtime. Use of literals results in hard parsing .
The performance will be poor.
You have to create view in design time, and then simply use select:
select * from mock_vu where chq_dt > (your_date) and something else

Need help using the "skatter" function with brushes.

I'm using Photoshop 7 right now. I want to use the scatter function with one of the standard brushes to make a star trail, but the problem is that the stars are too thick, there's too many of them. How do I tell it to draw less instances of the brush when I'm in scatter mode? So that it's only dropping 5 at a time or so?

I have a control bar for "Master Diameter" but I can't find anything that says "spacing."

Need help in using replace function with special characters

I have a column in a table where the data can contain ascii code for special characters such as an apostrophe.
The data looks like this:
CREEK'S LANE
ie for a street named CREEK'S LANE.
I want to replace the ascii representation with the apostrophe and have the returned data show up as: CREEK's LANE
When I try the query below I get prompted for substitution variable value.
I don't seem to be able to find the right syntax to make this query work.
SELECT REPLACE (street_name, ''', '''')
FROM
streets WHERE street_id = 1
Does anybody know how to do this?
Any help would be much appreciated.
Thanks.

GeorgeHa! The codes you specified rendered in the HTML, but showed properly when I listed your original posting above. I didn't understand what you meant initially because the 5-character string represenation got rendered as the quote that you said you weren't able to get - a display problem.
You're getting prompted for the substituon variable because of the ampersand; you appear to be doing this in SQL*PLUS. The first thing I would try is to SET DEFINE OFF when using the ampersands to see if that works. If That doesn't work check the docs to delmit the ampersand (I think its a backslash before it but can't remember offhand). Another, harder option might be to use the TRANSLATE function replacing the literal character instead of using REPLACE (though replacing a quote will be a little tricky). If you're on 10g also consider using the advanced quoting
Good luck!

Need help in Creating DB manually with OFA

Hi,
I want to create database in 10g manually and for this purpose
I need help.
since we can use OFA for storing Control files, and redolog file
and datafile by describing them in Create database command but
how to store any instance related file like spfile, pfile or network
related file.
once the oracle 10g database software is installed then if we want
to create database then how can we separate the database file and
all other instance files from software binaries because I've noted
that creating database with DBCA create all instance files along with
binary files of the software although DBCA give you option of creating
database related file in some other location/directory.
kindly help me in this I want to achieve above task in compliance with
OFA

D.AbbasiTHe OFA spec (as best I recall) states that one of the levels of directory for all of your data files will be the db name. So if you name your database 'orcl', every file system in which you keep any files related to 'orcl' will be in a directory name 'orcl'.
As for what happend when you created your db. Oracle will default to putting things in the Oracle home structure because that's the only thing he can guarantee will be there. But you had the option (indeed, the obligation) to override these defaults.
BTW, when using dbca, if you chose any of the pre-canned database types, the database will be created by doing a restore from a pre-canned backup. If you chose 'custom' database, the database will be created by way of a CREATE DATABASE script. It would be instructive time well spent for you to go through dbca and select 'custom database', pay attention to all of the options as you work through, then at then end, deselect "create database" and select "generate scripts". Do the same for one of the pre-defined database types. Then study the scripts generated by each method.

        Thanks,

This very simple: We cannot use dynamic SQL from used-defined functions written in T-SQL. This is because you are not permitted do anything in a UDF that could change the database state (as the UDF may be invoked as part of a query). Since you can
do anything from dynamic SQL, including updates, it is obvious why dynamic SQL is not permitted as per the microsoft..
In SQL 2005 and later, we could implement your function as a CLR function. Recall that all data access from the CLR is dynamic SQL. (here you are safe-guarded, so that if you perform an update operation from your function, you will get caught.) A word of warning
though: data access from scalar UDFs can often give performance problems and its not recommended too..

Help asap - creating Web page with templates

Hi,
I need help asap, im using BPC Web (my system BPC 75 SP04, MS version and there is not a lot of info on the web).
How can I create a web page using one of my Excel templates (the ones created for the application, to upload data)...
I've tried searching the templates inside Web ready Files but doesnt work for me... the only files available that appear are Temp.txt
I read about reports... but these are supposed to be created via "build a dynamic report" and i already created all my templates in a certain way. Also, Web ready Book only works with REPORTS right?
Thanx in advance.

Hi Sorin,
Thank you so much for the response, just want to clear this out:
You wrote:
1. Excel reports can be used just with BPC Excel client. - do you mean the "BPC dynamic reports"?
2. You can not use these reports into Web. - my excel reports?

Anybody experience with creating timelag function with FOX?

Dear All,
As can be seen from my former thread Katie announces that financial functions are not moved to IP. And nowadays these aren't available in BW-BPS either.
I'm just wondering if anybody has experience with creating financial unctions like timelag, allocation, IRR, accumulated balances etc in FOX?
And if so, how complicated is this. Any examples would be most appreciated.
Kind regards, Harjan

Hi Hatter,
thanks for the answer.
But what do you think about the ICY DOCK?
If you only want to use two drives, OWC has a nice
$67 dual drive black metal case.
I don't think that it is fast enough. Check the parameters:
"Maximum Data Transfer Rate: 1.5Gb/s (or 100MB/sec)"
Or FirmTek with a
much better $199 case with 3-speed fan for best
cooling.
Yes. This is fine. Here there is:
"High-performance storage data transfer up to 3.0Gbps (300MB/sec) per drive"
But what about this ICY DOCK? Although I know that it is not the most important part when we are talking about RAID disks, but this enclosure looks really nice. Will it work as good as it looks like?
PS: beware of anyone calling a device "hardware RAID"
when all it does is use an Oxford bridge.
How do you know that there is used an Oxford bridge, and why it work bad (as I suppose)?

Newb help on creating photo slideshow with different music tracks

I am interested in ultimately creating a DVD for a friend with pictures of their family. I would like to have different soundtracks play with fading in and out if possible; different effects on the transitions too (if possible). With iLife I know you could just use iDVD and play 1 track in the background. I would like to try iMovie.
I couldn't find any support tutorials or information in Apple Support.
Can anyone tell me or direct me to a place that would give the steps for a slide show, adding music, and exporting to DVD?
Thanks.

Can you enlighten me on this? and what program would you recommend for this?
While this can be done totally in iMovie '08, my preference would be to add the audio using GarageBand.
1) iMovie '08 strategy: In iMovie '08, simply create your video slideshow track first. Once satisfied with the video, titles, transitions, start adding your audio. Simply drag an audio file from the media browser or "drop import" a file from the Finder and "pin" it a your video clip. Once pinned to a video clip, adjust the "in" and "out" handles to select the exact portion of the music you want and adjust the fade in/out if necessary. When you have finished with this, slide the music to align it with the video track as desired. Now repeat theses steps to add the rest of your music.
NOTE: I prefer pinning all of the music to video clips so I can control the overlap. (I.e., have one file fade out as another is fading in.) However, there is a problem if you want the music to start during a "title" segment which does not overlap the actual slideshow video. In this case you may wish to place the first music file in the background and use the "Trim Music" option to select the actual portion to play in the background since you cannot slide background music for alignment to the video.
2) If you plan to use GarageBand, share/export your iMovie '08 video only project to your hard drive and then import it to a GarageBand Podcast project. In this case, each music file can be placed in a single audio track after appropriate trimming, or occupy its own audio track/alternate between two audio tracks to allow overlapping of files if desired. I prefer GarageBand since you can control the volume of individual tracks continuously, create custom fade contours, adjust track/master volumes as a whole independently, adjust the emphasis of frequency response ranges, "pan" the music, etc. as you mix and match your "musical collage" of sounds.

Try this: Go to this page but don't fill out the form. Instead, click on the "Forget your Apple ID?" link and fill out the form on the next page with the relevant information. It should be able to give you any Apple IDs you have set up in the past.
Hopefully you'll find that, under the .Mac address you're using, you actually had a separate +Apple ID+ that you can use to log into your previous Discussions account. (Note that your Apple ID is not the same thing as your forum alias and is not necessarily your email address.)
