DECODE versus creating a separate table and doing a join

Hi,
This question is on what Oracle does internally for the decode function on a field value.
I have two options:
(i) use the decode function to do a quick and dirty SQL statement
(ii) create a table that has the results what that decode will do, and do a join with that table.
I tend to shy away from using decode in SQL, since I hate the idea of putting business information into an SQL statement, and also I thought using functions of any kind slowed SQL down, and that one should limit it as much as possible "standard" SQL.
Is the gain from using a separate table real, illusory or is it worse than using DECODE?
Thanks,
Regards,
Srini

Thanks for all the responses. I talked with my DBA and decided to go with the table option rather than the decode option. Here are the reasons.
1. Mixing business information in your program is never a good idea (this of course goes beyond just SQL/Oracle, applying to all programming). This is related to what you mentioned, Kevin. I don't want to restrict the names in my tables simply because I have hard-coded something into my program. Over a period of time, this would result in a minefield of decodes.
2. I forgot to mention - the decode would be in my 'where' clause - that is why I had the question on speed. It seemed to me that if the system had to translate each field, it could obviously not take advantage of any indexing the column had, and would be slower. Cartesian products are bad enough, we don't want a computation to be tacked on to it as well, right?

Creating 2 separate tables with thin borders

I am trying to create 2 separate tables that have a thin
border and a space between the 2 tables. I am new to CSS but have
used Dreamweaver since its infancy,
Check this link for what I am referring to
http://www.sprucebodylab.com/index.php
Thanks

Many ways to do that. An easy way would be to construct an
outer table
container with two cells, and insert an inner table in each
cell. Thin
borders require CSS styling.

I transferred files and photos from MacBook to iMac via ethernet cable and using migration assistant. However every time I transferred, it created a separate user and it transferred all files and photos again and again. So now I have 3 users accounts ?

I transferred files and photos from MacBook to iMac via ethernet cable and using migration assistant. However every time I transferred, it created a separate user and it transferred all files and photos again and again. So now I have 3 users accounts with all files and photos saved 3 times on same iMac !! Any idea how to avoid this ?

Yes, you ran into a very understandable problem.
When you use Migration Assistant, it cannot over-write the account that you happen to be using at the time. Upon migrating accounts, it will tell you that it is going to create a new one, but that message is easy to miss.
If you have three identical accounts, log in to the account you want to keep, and delete the redundant ones in System Preferences > Users & Groups.
Now that you know, the easiest way to migrate accounts is to use Setup Assistant when you first get a new Mac. That eliminates any possibility for this to occur, but most people are so eager to use their new Mac that they elect to migrate later.
That's OK too, but in that case you would want to create a temporary account whose sole purpose is to run Migration Assistant so that you may migrate your old one with an identical name. Be sure to give the new account Administrator privileges. When that finishes you would log in to the newly migrated account, and delete the temporary account.

PowerPivot - Create a Lookup Table and Calculate Totals via PowerQuery

Hi,
I have got a question to powerpivot/powerquery.
I have got one source file "product-sku.txt" with product data (product number, product size, product quantity etc.).
In powerpivot I created via this text file 2 powerpivot tables:
product-sku and
products.
The "products" table is a lookup table and was created via powerquery using the columns prodnumber, removing the prodsize and the prodquantity columns and then removing duplicates.
My question: How could I show/leave a column prodquantity in the lookup table "products" which shows the total of all sizes per prodnumber?
I need this prodquantity in the lookup table to do a banding analysis via the "products" table (e.g. products with quantity 0-100, 101-200 etc.).
I give you an example:
source file columns (product-sku.txt):
Source
Date
ProdNumber
ProdSize
ProdQuantity
ProdGroup
ProdSubGroup
ProdCostPrice
ProdSellingPrice
The powerpivot table "product-sku" contains all columns from the txt file above
The lookup table "products" created via powerquery has the following columns:
Source
Date
ProdNumber
ProdQuantity (this column I would wish to add; if a prodnumber 123 had two sizes (36 and 38) with quantities of 5 and 10, the prodquantity should add up in the lookup table to 15. How could this be achieved?)
I enclose a link to my dropbox with example files: PowerPivot-Example-Files
Thank you for any help.
Chiemo

Chiemo,
If you would like to consolidate to one table as Olaf has suggested, that would be very easy to do. I have included the modified DAX for the calculated column below. This calculated column would be created in the 'product-sku' table itself.
You are correct in your assumption that you need an explicitly calculated column to most easily do banding analysis.
Olaf is correct that avoiding the creation of a separate 'products' table as you have done is a good idea. I was not thinking about modeling best practices when I replied. If the only purpose of your 'products' table was to create this calculated column,
then I do suggest deleting that table and implementing the calculated column in 'product-sku' with the DAX below.
Edit: If you need to use 'products' as a dimension table which will have a relationship to a fact table, then it will be necessary to keep it. PowerPivot does not natively handle a many-to-many relationship. Dimension tables must have a unique key. If [ProdNumber]
is the key, then it will be necessary to have your 'products' table. If you need to implement a many-to-many relationship, please see this
post as a primer.
=
CALCULATE (
SUM ( 'product-sku'[ProdQuantity] ),
'product-sku'[ProdNumber] = EARLIER ( 'product-sku'[ProdNumber] )

Creating a master table and using it to populate other tables.

Hi everyone.
I am a novice at using Numbers and I need some direction.
I am looking to create a master table with information for our summer camp. This table will include vital information such as name, address, etc. along with cabin assignments, tuitions received, and more.
We will separate this information into smaller tables that different portions of that master table for specific use. Such as: names and addresses for leaders, names and tuitions for registration, etc.
My goal is to type the information into the master table and have it update the other tables automatically. Can someone direct me how to format the master and sub tables so that this is possible?
I would greatly appreciate it and it will greatly reduce the record-keeping time for our camp.
Thank You!
Roy

Hi Roy,
Welcome to the Numbers discussions. You are giving us a tall order, especially when we don't know your level of experience in programming spreadsheets.
Here are a couple of basics to start the conversation...
In normal spreadsheet programming, we Pull data from one location into another, we don't Push it or Send it. This should help you to understand that the hard work is done in the sub tables, not the master.
You will use LOOKUP functions to pull the data to your sub tables. Download the Numbers User Guide and the Formulas and Functions User Guide and read up on them.
In your master table, make sure you have one column that uniquely identifies each participant so it will be easy to reference that person in your sub tables.
Regards,
Jerry

Create a Z-table and fill it with value and transport everything

Hi
I would like to create a Z-table, fill it with values and then transport everything.
This table will not be updated in the productions system.
Delivery class = C Customizing table, maintenance only by cust., not SAP import
Data Browser/table view maint = Display/maintenance allowed
Field: MANDT, etc. etc.
Technical settings: Data class = APPL1, Size = 0, Buffering switched on, Fully buffered.
I also create the Table maintenance generator
When I fill my table with values, these will not be saved in my change request.
What I'm doing wrong?
Thanks // Peter B

Go to
se11>utilities>table maintenance generator-->there u fill
Fungroup group (inthe function group u give any a z name related to ur table name it create automatically)
package
maintenance screen type and screen name
After this save and activate.
Then goto
Utilities>TABLE CONTENTS>CREATE ENTERIES

If I get the Iphone, can I create a separate account and move all my music sucessfully from my Ipod to my new Iphone?

I want to know if I can create a separate account from the one that my ipod belongs to and transfer all my music and movies to that new account which will have my iphone on it. Not all of my music is bought from the Itunes store though. I downloaded some from youtube and CDs. Can I also transfer those songs onto my Iphone?

There's various ways of managing multiple devices on a single computer. The following document is worth checking through:

How to Create a Separate N and G Network?

I have been reading post after post, and none of them gives enough explicit detail for me to figure this out. I want to create 2 separate networks in my home, one just 802.11n the other 802.11g. The n is for internet and time capsule with my MacBook Pro, the g for my iPhone. I have a Time Capsule, an Airport Express and a DSL modem.
Right now I have the DSL modem connected to the TC and it set for 802.11n only @ 5 Ghz. The Airport Express is connected via an ethernet cable to the TC. What settings must I change in the Airport Express "Manual Setup" section to ensure no problems?
I have heard of turning of DHCP and something about SSID. I have no idea what those are. I have a static IP address from AT&T.
Thanks so much!

I've read a number of posts on this topic and also read the TC manual. I am still having a problem getting this to work so I am hoping someone can provide a step by step based on the following info:
I have a cable modem connected to the TC using ethernet.
I want my Macbook Air and Apple TV to connect to the TC wirelessly at 5Mhz. I called the TC "Home_5Mhz" with WPA2 Personal active.
I have a b/g AEBS connected to the TC using ethernet. I called the AEBS "Home" with WPA2 Personal active.
I want to connect my iPhone, iMac G5 and Powerbook G4 wirelessly to the AEBS b/g network.
I want all of my devices to have access to the Internet at the highest speed possible without degrading 802.11n performance on the TC.
The problem I'm having: Access to the Internet from the iMac, Macbook Air, and Apple TV is sporadic. Sometimes it works, most of the time is doesn't. The TC is set to find a channel automatically; the AEBS is using Channel 11. The two computers seem to recognize the TC as a storage device and I can back up to it. It is very slow backing up the iMac G5's full 250gb hard drive (supposed to be, right?). It's the Internet connection that doesn't appear to be working consistently. By that I mean I get the Safari web page saying that I'm not connected to the Internet (page with Diagnostic button). Running Diagnostics has not resolved the problem. I have tried resetting both the TC and AEBS to factory specs and starting from scratch but the problem persists.
I'm pretty sure it's just a simple setting I have yet to identify, I just can't figure out which one it is. Currently the AEBS is in bridge mode allowing b/g devices to connect to the Internet. "n" devices cannot most of the time unless I change the AEBS from bridge mode to share an IP address. Then I can connect the "n" devices but I think it's happening via the AEBS not the TC.
Any suggestions or step by step info (link?) would be greatly appreciated and I offer my thanks in advance.

Separate table and index data in RAC database

Hi Experts,
Our database is Oracle11g RAC database. I need your expertise on this
Do we need to retain the table and index data in two different tablespaces for performance perspective in RAC database too?
Please share your practical experience…Thanks in advance.
Regards
Richard

In my opinion, if there is striping implemented then performance shouldn't degrade even if the index and table blocks are in one tablespace. Exactly.. striping is NOT a good idea at tablespace level as a tablespace is a logical storage device. It is very difficult to stripe comprehensively/correctly at that level, if not impossible.
Striping is a function of the actual storage system and need to happen at physical level. A proper RAID0 implementation.
So the question about multiple tablespaces for a performance increase should not be about striping - but about issues such as data management, block sizes, transportable tablespaces and so on.
Thus my question (at the OP) - what performance problems are expected and are these relevant to the number of tablespaces?

Separate table and figure numbering sequences

I need some pointers and guideance on how to setup autonumbering for tables and figures separately. As it is, the number sequence advances upon usage by a table or a figure. For example, Table 1, Figure 2, Figure 3, Table 4. What I need in that case is Table 1, Figure 1, Figure 2, Table 2.

Steve,
The easisest way is to use what's called a series indicator for you autonumber sequence. This consists of a single letter at the star of the autonumber. Typically, one could use F:<n+> for figures and T:<n+> for tables. FM will then number these streams differently. You can make things more complex in your setup (and much easier for the authors) using a numbering matrix where parent heading tags reset the lower level counters (which is what Peter was alluding to).

How to create one master table and two detail for it

I have one table , imagine it like mastertable( empid,deptid );
and two different tables like employeetable(empid ) , departmenttable ( deptid )....
I dont have any relation on database side. I need to create view link and ı need to use only one master table for two detail tables.
How can ı manage this scenerio ?
thanks...

yes Shay ı really want to use two detail table in one UI as you suggest in your blog. But in that scenerio probably tables have link in database side with foreign key. My detail tables dont have any connection in database side with my master table. How can ı link them under one mastertableVO ?
I am really sorry about my bad explanation. I am a newbie and probably ı dont know the correct words to tell my problem.
Thanks for your time...

How to create solved fact table and corresponding cube

Hello,
I want to create cube with solved fact table. It means, i need to feed data for higher levels of dimension also from fact table instead of aggreting from base level.
I am using star schema and AWM 10g R2 for creating cube.
If anyone knows how to do this, i would be very benificial.
Thanks

I have generated parent child script using cwm2_olap_pc_transform.create_script. After running this generated script, it has created 3 table/view.
My Base Parent Child table is like this:-
drop table PARENT_CHILD;
create table PARENT_CHILD (PARENT varchar2(30), CHILD varchar2(30));
insert into PARENT_CHILD values ('Eligible', 'Compliant');
insert into PARENT_CHILD values ('Eligible', 'Non-Compliant');
insert into PARENT_CHILD values ('All', 'Eligible');
insert into PARENT_CHILD values ('All', 'Ineligible');
insert into PARENT_CHILD values (null, 'All');
After running generated script thru cwm2_olap_pc_transform.create_script, it has created :-
Table - PARENT_CHILD_SOLVED
View - PARENT_CHILD_SOLVED_view , PARENT_CHILD_view
This script also inserted data in above table/view. (5 rec in each). Table/View structure is like this:-
SQL> desc PARENT_CHILD_view
Name Null? Type
GID NUMBER
CHILD1 VARCHAR2(30)
CHILD2 VARCHAR2(30)
CHILD3 VARCHAR2(30)
Data:-
0 All Eligible Compliant

1 All Eligible
1 All Ineligible
3 All

CHILD2 VARCHAR2(30) ,
CHILD3 VARCHAR2(30) ,

Data in Fact Table:-
insert into HCP_PC_FACT values('Compliant',0,'All','Eligible','Compliant', 100);
insert into HCP_PC_FACT values('Non-Compliant',0,'All','Eligible','Non-Compliant', 200);
insert into HCP_PC_FACT values('Eligible',1,'All','Eligible',null, 300);
insert into HCP_PC_FACT values('Ineligible',1,'All','Ineligible',null, 400);
insert into HCP_PC_FACT values('All',3,'All',null,null, 500);
I am not sure how to create level, level attr, dim attr for such dim.
All CWM2 validation API shows that my all dims, cubes are valid but when I try to create presentation thru JDev it hangs after selecting Parent-Child Measure.
Any complete working exapmle will be helpful.
P.S. One more query I have can we have one solved and one un-solved dim in the same cube/measure?

How to create a cluster table and cluster view?

Hi,
Can anyone guide me in creation of cluster table in general and also creation of cluster view?

Hi,

Repeat to create multi-column table

I'm trying to use a spry:repeat directive to create a
two-column table. What I would like to have generated as a result
of the repeat is something like the following:
<table>
<tr>
<td>row[0] data</td>
<td>row[1] data</td>
<tr>
<tr>
<td>row[2] data</td>
<td>row[3] data</td>
<tr>
</table>
Using the spry:test directive it's easy to get only the even
rows in the first TD element, but I can't figure out how to
reference the data element for the second TD in each table row.
Here's what my HTML looks like:
<div id="thumbContainer" spry:region="dsPhotos">
<table border="0" cellpadding="0" cellspacing="0">
<tr align="center" valign="middle" spry:repeat="dsPhotos"
spry:test="loadThumb({ds_RowNumber}, {ds_RowCount})">
<td width="85" height="85"><img
src="thumbnails/{filename}" /></td>
<td width="85" height="85"><img
src="thumbnails/{filename}" /></td>
</tr>
</table>
</div>
The loadThumb function returns true for every other row. That
works correctly and I see the even-numbered items in the two
columns of each row. I've tried replacing the contents of the
second img src attribute with every imaginable combination of
dsPhotos.getData() and I can't find the magic combo that gets me
the filename of the *next* row. I did try different usages of the
ds_RowNumberPlus1 data reference but wasn't able to get that to
work either. I verified that if I create two separate tables and
use floating div's to get them to appear side-by-side and use
separate spry:test functions to get the even and odd rows, I can
iterate the data set twice and get the right contents in each
table, but I would like to be able to solve this with a single
table and a single iteration of the data set. Can anyone shed some
light on how I should reference the n+1th row in my HTML table
definition above?
Thanks,
Steve

XE provides the browser-based interface for 'convenience'. You could always switch to SQLPlus or use the SQL Window and enter it manually. You could do this after the table has been created by using a documented syntax such as this sample
ALTER TABLE sales
ADD CONSTRAINT sales_pk PRIMARY KEY (prod_id, cust_id) DISABLE;
found at http://download.oracle.com/docs/cd/B19306_01/server.102/b14200/clauses002.htm#i1002629
The referenced doc also shows how to create the constraint at the same time as the table.
