Hi all, this is a really simple application to record results of a questionaiire. Basically, each question can have multiple yes/no type answers.
Any help appreciated. Also going to develop a c# front end.
When I set the relationship between two tables with a one-to-many relationship and I want all records deleted from the many side when a row is deleted from the one side, how should I set the Insert and Update Specs (Delete and Update) CASCADE or NO ACTION?
Then if there is a lookup table on the many side how should it be set?
i am a beginner and any response will help me a lot.
i have 20 types of products,each product has about 40 fields, most of them are common fileds for all products, but some of them are unique.
the number of the unique fields of all the product types is 75.
the question:Should i build one products table with 75 fields and leave nulls where a field is not property of a product type?Or should i build a products table for the 30 common fields and a 20 different tables for each product type extra fields?Or just build 20 different tables each product type?
other ideas are welcome
I have decided to build a Football Pool app as a way of teaching myself asp.net with non code-generating tools. I am stuck on some basic DB design thoughts and would appreciate some feedback.
Right now I have pages that let me input some of the initial data like Users, Teams and Game Schedules. I need to be able to record whether a user has paid their weekly entrance fee but I don't know which table to store this info even what datatype would be the best solution.
Here is the table design I have so far http://www.insecurepc.com/FootballPoolDBDesign.jpg Before you ask, the users tables would be the asp.net 2.0 mambership ones which are too many to list...
Thoughts please. TIA
Hi,
we have records with login.out of employees.
i.e.
this is a set of login/out for an employee for 1 day (but the actual data shows 2 dates )
login 1/1/2005 15:00
logout 1/1/2005 16:00
login 1/1/2005 17:00
logout 1/1/2005 18:00
login 1/1/2005 23:00
logout 1/2/2005 1:00
login 1/2/2005 2:00 <-----------this is the reason why we need a new table called schedules
logout 1/2/2005 3:00 some employee goes over the next day to finish their shift
I think in order to get the proper Start Time and Stop time we need a new table called schedules.
schedules will contain employee work schedules, kindly help me design how to accomplish this.
question is, will it be for each day?
so I'll have 365 record per employee?
help me design the columns
employeeID, startTime,stopTime, workdate -do I need only four?
Thanks.

View 5 Replies View RelatedHi,Probably a very simple question but I'm afraid my experience at this issomewhat limited so...In a database with a many to one relationship, say orders to customers, isit preferable to have an UID for a customer and store this in the orderstable rather than the customer name, for example.CUSTOMERS++++++++++UID: Name: Address: Postcode: etc01 Alpha 12 Acacia Ave HN7YHH02 Beta 23 Acacia Ave HN6YTH03 Gamma 28 Acacia Ave HN7UYHORDERSCustomer Amount dateAlpha 100 20030823Alpha 250 20030824Beta 90 20030825Alpha 800 20030825Gamma 1000 20030826Or is it is better to have:ORDERSCustomer Amount date01 100 2003082301 250 2003082402 90 2003082501 800 2003082503 1000 20030826Assuming that the second option is the best, how far do I go? I can see howit would beof benifit to do this for orders and customers where there may beseveral hundred thousand orders and hundreds of customers, but for examplewould I need to do this for a customer contact database with titles - egeach title having a UID and using this ID in the customer table?Thanks for taking the time to read this. Any advice is gratefully received.Kind thanksChris S

How to design tables in SQL Server for the above.
Ok, I'm doing a football database for fixtures and stuff. The problem I am having is that in a fixture, there is both a home, and an away team. The tables as a result are something like this:
-------
Fixture
-------
fix_id
fix_date
fix_played
----
Team
----
tem_id
tem_name
-----------
TeamFixture
-----------
fix_id
tem_id
homeorawayteam
goals
It's not exactly like that, but you get the point. The question is, can I do a fixture query which results in one record per fixture, showing both teams details. The first in a hometeam field and the second in an away team field.
Fixture contains the details about the fixture like date and fixture id and has it been played
Team contains team info like team id, name, associated graphic
TeamFixture is the table which links the fixture to it's home and away team.
TeamFixture exists to prevent a many to many type relationship.
Make sense? Sorry if this turns out to be really easy, just can't get my head around it at the mo!
I would like to create a table called product. My objective is to get list of packages available for each product in data grid view column while selecting each product. Each product may have different packages type (eg:- Nos, CTN, OTR etc). Some product may have two packages and some for 3 packages etc. Quantity in each packages also may be differ ( for eg:- for some CTN may contain 12 nos or in other case 8 nos etc). Prices for each packages also will be different that also need to show. How to design the table..
Product name :
Nestle milk |
Rainbow milk
packages :
CTN,OTR, NOs |
CTN, NOs
Price:
50,20,5 |
40,6
(Remarks for your reference):CTN=10nos, OTR=4 nos
| CTN=8 Nos

I have a table with a user column and other columns. User column id the primary key.
I want to create a copy of the record where the user="user1" and insert that copy in the same table in a new created record. But I want the new record to have a value of "user2" in the user column instead of "user1" since it's a primary key
Thanks.
Hey all!
Sorry for the less then descriptive post title but I didn't find a better way to describe it. I'm developing an app in the express editions of VB and SQLserver. The application is a task/resource scheduler. The main form will have a datepicker or weekly overview and show all tasks scheduled per day. The problem is, I've got one or more people assigned to tasks and I wonder what's the best way to design this. Personally, I'd go for one Task table, a People table and a table that provides a link between them (several record per task, one for each person assigned linking TaskID and PplID). However, I don't see a nice way of showing this data to the end user, allowing him to edit/add etc on ONE screen.
To fix that the only way I see is just add columns to the Task table for every person with select boxes. This way everything can be done on one simple screen. This obviously does present some future issues.
On top of this, which people are available on a day varies and there should be an option to allow a user to set who is available on a specific day. Which would lead me to my first idea and add another table that would provide this. but then I'm having design issues again for the form.
I'm kinda stuck atm, can anyone shed some light on this. I'm sure there is an elegant way of doing this but I'm failing at finding it.
Thanks in advance,
Johan
Hi,
We're running a Sage CRM install with a SQL Server 2000 database at the back end. We're using the Sage web services API for updating data and a JDBC connection to retrieve data as it's so much quicker.
If I retrieve a record using the JDBC connection and then try and update the same record through the web services, the query times out as if the record is locked for updates. Has anyone experienced anything similar or know what I'm doing wrong? If I just use DriverManager.getConnection() to establish the connection instead of the datasource, and then continue with the same code I don't get these record locking problems. Please find more details below.
Thanks,
Sarah
The JDBC provider for the datasource is a WebSphere embedded ConnectJDBC for SQL Server DataSource, using an implementation type of 'connection pool datasource'. We are using a container managed J2C authentication alias for logging on.
This is running on a Websphere Application Server v6.1.
Code snippet - getting the record thru JDBC:
DataSource wsDataSource = serviceLocator.getDataSource("jdbc/dsSQLServer");
Connection wsCon = wsDataSource.getConnection();
// wsCon.setAutoCommit(false); //have tried with and without this flag - same results
Statements stmt = wsCon.createStatement();
String sql = "SELECT * FROM Person where personID = 12345";
ResultSet rs = stmt.executeQuery(sql);
if(rs.next()){
System.out.println(rs.getString("lastName"));
}
if (rs != null){
rs.close();
}
if (stmt != null) {
stmt.close();
}
if (wsCon != null) {
wsCon.close();
}
I am attempting to create a multi-record file (as described in my last thread) and have found the following set of instructions very helpful:
http://vsteamsystemcentral.com/cs21/blogs/steve_fibich/archive/2007/09/25/multi-record-formated-flat-file-with-ssis.aspx
I have been able to create a sample file with two of my record types.
I now need to build on this further, because I have 9 record types in total that need to be extracted to a single flat file.
does anyone have any ideas how I might extend the example above to include more record types or know of another means of achieving this?
Thanks in advance for any help you might be able to provide.
Hi
Can anyone advise me as to how I can add the date and time to 2 columns in the sql server database for each record that is added. I'd prefer not to use the webform. Can sql server add the date automatically to the row?

Hi All,I have a table in SQL Server 2000 that contains several million memberids. Some of these member ids are duplicated in the table, and eachrecord is tagged with a 1 or a 2 in [recsrc] to indicate where theycame from.I want to remove all member ids records from the table that have arecsrc of 1 where the same member id also exists in the table with arecsrc of 2.So, if the member id has a recsrc of 1, and no other record exists inthe table with the same member id and a recsrc of 2, I want it leftuntouched.So, in a theortetical dataset of member id and recsrc:0001, 10002, 20001, 20003, 10004, 2I am looking to only delete the first record, because it has a recsrcof 1 and there is another record in the table with the same member idand a recsrc of 2.I'd very much appreciate it if someone could help me achieve this!Much warmth,Murray

Could anybody help me with the following scenario:
Table 1 Table2
ID,Date1 ID, Date2
I would like to link the two tables and receive all records from table2 joined on ID and the record from table1 that has the most recent date.
Example:
Table1 data Table2 Data
ID Date1 ID Date2
31 1/1/2008 31 1/5/2008
34 1/4/3008 31 4/1/2008
31 3/2/2008
The first record in table2 would only link to the first record in table1
The second record in table2 would only link to the third record in table1
Any help would be greatly appreciated.

I've been looking for examples online to write a SPROC to get some data. Here are the tables.
Album_Category
AlbumCategoryID (PK, int, not null)
Caption (nvarchar(max), not null)
IsPublic (bit, not null)
Albums
AlbumID (PK, int, not null)
AlbumCategoryID (int, null)
Caption (nvarchar(max), not null)
IsPublic (bit, not null)
I need to return:
-[Album_Category].[AlbumCategoryID]
-[Album_Category].[Caption]
-[Albums].[Single AlubmID for each AlbumCategoryID]
-[Count of Albums in each AlbumCategory]
I hope I was fairly clear in what I'm trying to do. Any tips or help would be appreciated. Thanks.
I have a directory of user information. What I would like to do isallow someone to search for person X and then return not only theinformation for person X, but also the information for the next 15people following person X sorted alphabetically by lastname.So if someone searched for the lastname = "Samson", it would return:Samson, JohnSaxton, GregScott, HeatherSears, Rebecca.... (15 names following "Samson) ...How do you in SQL return a record set of X records starting atparticular record (e.g. lastname = "Smith)?Thanks in advance.

Hello. I have a database with a record that has two columns locked. descrip1 and descrip2. they are both nvarchar(max) columns. These are the only two columns of the record that remain locked. I am certain no user is accessing the record. I have even moved a backup of the database to my testing computer and the lock still exists. How do I remove the lock from these two columns on that particular record.
I can edit these two columns on other records. I have researched "Unlock" on MSDN but it doesn't seem to apply to t-sql. Any help would be greatly appreciated.
Thanks. Gary.
I am trying to update a record in a table based off of criteria of another record in the table.
So suppose I have 2 records
ID owner type
1 5678 past due
2 5678 late
So, I want to update the type field to "collections" only if the previous record for the same record is "past due". Any ideas?
I have not yet succeeded in getting an aswer to this in a previous post, so I'll try again and rephrase the question
I have 2 fields, 1 called 'Created' the other 'Updated'
I would like to create a function, user procedure ,whatever in SQL something along the lines of...
FUNCTION myUID()
RETURN Date(Today)+Time(Now)+USERNAME
END FUNCTION
so that the value returned by the above pseudo code is something like '20080526T21:01:05.620SamL' where the date part is in yyyy0m0d format
I have got this working fine for the default 'Created' field but the calculated (and persisted) field comes up with something about being non-deterministic and refuses to play
Clearly something along these lines is a very straightforward requirement (I have it working fine in my 20+ year old database) , but have spent a week trying to get an answer (even from this forum) without success, so would be grateful for any help that you can provide me with to get round this barrier
Hi All,
I am trying to create package something like that..
1- New Customer table as OleDB source component
2- Lookup component - checks customer id with Dimension_Customer table
3- And if same customer exist : I have to update couple fields on Dimension_Customer table
4- if it does not exist then I have insert those records to Dimension_Customer table
I am able to move error output from lookup to Dimension_Customer table using oledb destination
but How can I update the existing ones?
I have tried to use oledb command but somehow it didnt work
my sql was like this : update Dimension_Customer set per_X='Y', per_Y= &Opt(it should come from lookup)
I will be appreciated if you can help me...
Hi,
How can we insert multiple records in a OLEDB destination table for each entry from the source table.
To be more clear, for every record from source we need to insert some 'n' number of records into the destination table. this 'n' changes depending on the record.
how is this achieved.
thanks.
I tried checking to see if the point at which the reader was, that if it was the record I am looking for to go ahead and add the table data to a label. But for some reason it's only taking the first record in the database and not the one I thought I was at.[CODE] public void UpdateMaleHistLbl() { SqlConnection conn = new SqlConnection("Server=localhost\SqlExpress;Database=MyFamTree;" + "Integrated Security=True"); SqlCommand comm = new SqlCommand("SELECT * FROM FatherHistTable, MotherHistTable, UsersTable WHERE UsersTable.UserName = @usrnmeLbl ", conn); comm.Parameters.AddWithValue("@usrnmeLbl", usrnmeLbl.Text); conn.Open(); SqlDataReader reader = comm.ExecuteReader(); while (reader.Read()) { string usr = reader["username"].ToString(); usr = usr.TrimEnd(); string pss = reader["password"].ToString(); pss = pss.TrimEnd(); if (usrnmeLbl.Text == usr) { if (hiddenpassLbl.Text == pss) { maleHistLbl.Text = reader["GG_Grandfather"] + " > "; maleHistLbl.Text += reader["G_Grandfather"] + " > "; maleHistLbl.Text += reader["Grandfather"] + " > "; maleHistLbl.Text += reader["Father"] + " > "; maleHistLbl.Text += reader["Son"] + " > "; maleHistLbl.Text += reader["Grandson"] + " > "; maleHistLbl.Text += reader["G_Grandson"] + " > "; maleHistLbl.Text += reader["GG_Grandson"] + "<br /><br />"; } } break; //exit out of the loop since user found } reader.Close(); conn.Close(); }}[/CODE]Thanks in advance
