Does A Database Table Need An Id Column?
Dec 14, 2005I always create database tables with an id column with an autoincrementing number.
Does a table actually need this or can I remove this field if I don't refer to it?
thanks

Feb 13, 2015I have researched how to put a URL column in my SQl Server 2008 database and table. I have tried varchar(max) and varchar(1000) and then done what I found online by inserting into the url with ' ' around it and then I ODBC into Access and it does not look like a link. Cannot link on it and have it go where it needs to. I have also tried this in the front-end application and it does not look like a link. It does not respond either.

Not Able To Create An Identity Column For An Existing Database Table
Feb 1, 2008I am working with a table in SQL server. I have a column that I want to designateas an identity column. I am not able to do this, because the field for "Identity Specification" is not editiable.
What I did was I went to sql server, right clicked and selected "Modify".The column properties dialog box/edit grid is then displayed with attributesthat I can modify.
There are two major nodes in this dialog box. One is named "General" and the otheris named "Table Designer". I expand the "Table Designer" node and then go to the node labeled "Identity Specification" It is here where I would like to edit thevalues.
The values that are listed for edit are listed below. BUT, the problem is thatI can place my cursor in those fields, but I am not able to change/edit them.Can anyone tell me what the problem is here? and how I can fix it?

Counter For Max Tickets - Refer To A Database Table Row/column Etc
Feb 7, 2008I posted a thread in the Getting Started forum about how to make a counter for maximum tickets : http://forums.asp.net/t/1215258.aspx
but maybe this is a more appropriate forum for this subject.
In a school project, we are making a website for a fictional concert/festival (using Visual Studio 2005, C#). On that site users can register and order tickets.
We have access to an SQL-database, by the way, where we can create tables etc.
We want the maximum amount of tickets to be 10000 per day. The festival is supposed to last from friday to sunday.
What would be the best way to do this programatically? The counter should maybe be in an own database table?

SQL 2012 :: Query Based On Column Name / Setting Up Database Table
Oct 30, 2015I have a set of data spread across a number of tables regarding stock market data. An example of this follows:
Market Capitalization...
Date CompA CompB
01/01/11 100 5
02/01/11 102 4
Share Price....
Date CompA CompB
01/01/11 100 100
02/01/11 101 99
Event Data...
Date Company
01/01/11 CompA
02/01/11 CompB
Pretty simply, I need a way to retrieve the market capitalisation and share price data based on the event data. So for instance I say 'oh, there is an event on the 01/01/11 involving company A, the market capitalisation on this day was 100, then for the next event it was 4 for company B.
I can also transpose the data so that the company name is in the rows and the dates in the columns for the market cap and share price tables, but this leads to the issue that when I try and get the data, I don't know how to query the correct company for that date.
For instance:
SELECT Event.Date, Event.Company
FROM Event
how do I now say.....
SELECT MarketCapitalisation.Column
WHERE Column = Event.Company
AND MarketCapitalisation.Date = Event.Date.
I have played around with a few basic joins, but I am having issue with the principle of that second to last line of SQL (so only getting the correct column).
I still have a copy of the data in excel so can flip things around as needed, but that would only mean that I would have the issue of WHERE Column = Event.Date instead of Event.Company.
SSIS Database Table To Flat File Destination With Column Headings
Sep 8, 2006Hi,
I have a simple enough task to complete that I can€™t seem to find the answer to.
The task is this €“
Select table x from the database and write it to a flat file complete with that tables column headings.
Now I€™ve managed to set up an ole db datasource and selected the table and I€™ve also linked it to the flat file output. So now I can generate a flat file from the database. However no column headings appear in the flat file.
I can€™t seem to find anywhere (like a checkbox) that will also output the column headings to the flat file.
Now I can add in Headings manually in the properties of the Flat File Destination object but the columns that appear in the flat file don€™t appear to be in the order that I requested them in the SQL.
So the question is how do I automatically have the column headings appear for flat file output (ideally without me having to manually add them in).
If it can€™t be done and I have to use a vb.net script instead then would anyone have an example script of how to do it?
Thanks in advance for anyone who manages to answer this.
Matt.

How To Create Key Time Column And Key Column For A Case Table And A Nested Table For Time Series Algorithm?

Questions On Key Column In Case Table And Key Time Column In Nested Table Using Time Series Algorithm
Jun 4, 2007Hi, all experts here,
Thank you very much for your kind attention.
I am confused on key column of case table and key time column of nested table by using Time Series algorithm.
In my case, the case table structure is as below:
Territory key text (the ID is actually dimrisk_key, in this case, I use the name column binding to combine the Territory column of case table Dimrisks),
While the nested table structure is as below:
Cal_month key time (in this case, actually the ID is dimdate_key, again, I used name column bining property to bind the Cal_month to the ID)
So my question is, as the key column of case table has been set to be Territory, as a result, does the model training still cover all the cases (rows) based on the ID of the table?
Also, in the nested table, as the key time column has been set to Cal_month rather than Dimdate_key of the nested table, as a result, would the single series based on the cal_month?
Hope it is clear for your advices and help.
And I am looking forward to hearing from you shortly.
With best regards,
Yours sincerely,
