Hi is it possible to implement type inheritance in SQL server? and is it also possible to define user defined types's operators/functions in a level lower than SQL?
View 6 Replies View RelatedFirst of all I apologise if this is a dumb question. I am from a object-orientated background and am trying to convert a legacy application to have an SQL backend. My SQL knowledge is fairly basic...
I have an application where I am trying to maintain a list of recipies that are composed of base ingredients.
No problem so far two tables Ingredients and a Recipie table coupled with another table Element which maintains the many-to-many relationship.
Ingredients
ID (PK)
Name
Cost
Recipie
ID (PK)
Name
Element
ID (PK) <-- maybe not necessary
RecipieFK <-- the recipie this element belongs to
Amount <-- the amount of the ingredient used (e.g. 200g)
IngredientFK <-- the ingredient that makes up this element
My problem comes because Recipies can also form part of other recipies, for example the White Sauce is composed of
Milk (ingrediant)
Flour (ingrediant)
Butter (ingrediant)
However a lasagne is composed of
Minced Beef (ingrediant)
Tomatoes (ingrediant)
Lasagne Pasta (ingrediant)
Onions (ingrediant)
Basil (ingrediant)
White Sauce (recipie)
In a OO environment this is simple, I have a base class Ingredient and a Recipie class derives from Ingredient. Each Recipie contains a list of Ingredients that make up the dish. As Recipie derives from Ingredient that list of ingredients can include other recipies.
The best SQL I've come up with so far is changing the Element table to be
ID (PK) <-- maybe not necessary
RecipieFK <-- the recipie this element belongs to
Amount <-- the amount of the ingredient used (e.g. 200g)
IngredientFK <-- an ingredient that makes up this element (can be NULL)
ComplexIngredientFK <-- a recipie that makes up this element (can be NULL)
And to insist that one of IngredientFK or ComplexIngredientFK must be NULL and the other cannot be. This bothers me because it doesn't feel right. There's redundancy built into this design, you'd have to use tiggers to wipe one FK if the other was specified and it is crying out for a more elegant solution, but so far I have drawn a blank.
Can anyone suggest a more appropriate schema!
Thanks in advance

Hi, I am running SQL SERVER 2005 Enterprise Edition under Windows 2003 server. I would like to use table hierarchies (inheritance) in SQL 2k5 just as we do it in informix,PosgresSQL and other databases. Can we do the same in SQL 2k5 also? If yes, then how?
Thanks
Is there a table inheritance in SQL ?
I need to make two tables which are identical :
1. Recharcheable battery
2. Primery Battery
Is there a way to make a 'Battery' Table and create the 1 and 2 tables with inheritance in a way that when i change a field from smallint to int in the Battery Table , The same fields in the 1 and 2 tables will be replaced too?
(I work with SQL Server 2005)
thanks.
hi folks,i'm puzzled over this one, anyone with some solid db experience might beable to enlighten me here.i'm modelling a file system in a database as follows, and i can't figure outto cleanly implement an inheritance mechanism.i have a hierarchy of folders in an sql table. every folder has aparentFolderID, if this value is 0 then it means it's a root folder.then, in a 'files' table, every file has a parentFolderID to give it alocation in the structure. fairly basic.the hard part is that each file record has an attribute 'STYLE' that can beexplicitly specified, or inherited from it's parent folder, or it's parentsparent folder, or.. all the way back to the root.the 2 ways i've come up with representing it are:1) if the style is being inherited, enter a null value in the STYLE field.then to figure out what style applies to a file or folder, i trace backthrough it's parentFolderID records until i find a style attribute that isnot null.the good thing about this is that if i change the style that is applied tothe entire filesystem, it only takes one update.the bad thing is when i want to figure out what style applies to a file, ihave to traverse back through possibly several records to locate the folderthat actually specifies the style being inherited by the file.2) explicitly state all style values in each record.this is good for accessing the style of a file or folder because you get itstraight out first time from the db.the bad thing is if i update the entire file system, i might have severalhundred / thousand update sql statements to execute to update all the valuesin every folder and every file. nasty!thanks for any help, i'm really stumped with this and i'm thinking theremust be a more elegant way to implement inheritance.thankstim
View 2 Replies View RelatedThe Adventure Works Model comes with 'Sales Person' entity inheriting 'Employees'. The Binding dropdown in the inheritance property for 'Sales Person' provides a 'FK_SalesPerson_Employee_SalesPersonID' choice.

i have two table. i want to create a veiw for display data which in both table(parent class table and a child class)
how can i do?
Hi,
in my application, the data is in hierarchical format. there is a tree with set of nodes having parent child relationships. this data can be stored either through adjacency or nested set model approach. this is fine. but the issue here is that each child node inherits the properties of its parent node, parent's parent node and so on until the root node. lets say root node has two attributes A1 and A2 and they are stored in two columns in a table. but its child nodes inherits this data from its parent and it has its own extra attributes. so should I copy parent's data for the child node as two additional columns? the problem is that there are around 15 levels in the tree and the attribute list grows from top to bottom in the tree. lets say I need to find all the attributes for a leaf node in the tree (both direct and inherited), if I am not storing the inherited attributes for each node, then I need to walk-up the tree and find all the inherited attributes. there are around 30K nodes and each node has around ten attributes. xml is not option because of large volumes of data and auditing and reporting on individual nodes. what is the best way to store this type of data? my current approach is to have an attribute table having nodeid as a foreign key and only store the direct and NOT the inherited attributes of the node in the table, but this means to find all the attributes for the node, I need to gather the attributes of all the parents until the root node. I can't see any easy way out for this.
Hi,
I have a folder structure of reports like this
Home
|
/
A B
Now, suppose I have created this folder, A first and user, say A_User is given permission to view this folder. I am expecting this user to browse from 'Home' to A folder but as you know to browse folder 'Home' he must also be added to 'Home' folder . So I add him to 'Home' now.
The problem comes when I add new folder B, for user B_User. The moment I add this folder A_User is also added to folder B because of the inheritance of users to child folders.
So user A is able to see both A and B folder....and thats my problem, he is supposed to only A folder and not B
Is there any way to disable this inheritance feature ??
I tried deleting A_User from B with a script using "InheritParentSecurity" method of ReportingService but it says that it can not delete inherited users.
How can I fix the problem ? without need to manually delete users from folders ??/
thanks

Hi, I am trying to edit some data from a SQL2000-datasource in ASP.NET 2.0 and have a problem with a column that has bit-data and is used for selection. SQL2005 works fine when declaring <SelectParameters> <asp:Parameter DefaultValue="TRUE" Name="APL" Type="boolean" /> </SelectParameters>When running this code with SQL2000, there are no error-msgs, but after editing a record the "APL"-column looses its value of 1 and is set to 0. Looks like an issue with type-conversion, we've hit incompatibilities between SQL200 and 2005 with bit/boolean several times before. So, how is this done correctly with SQL2000? (I've tried setting the Type to "int16" -> err. Also setting Defval="1" gave an err) ThanksMichael
View 2 Replies View RelatedI've created a small company database where the tables reside in a SQLServer database. I'm using Access 2000 forms for a front end.I've got a System DSN set-up to SQL Server and am using links withinAccess 2000 to get to the SQL Server tables.My forms worked fine until I made a few minor changes to the databaseschema on SQL Server (e.g. added a foreign key, or added a column).After that, all the links break - I click on a table link and get anerror msg like "invalid object name."Deleting the links after a schema change and re-adding the links seemedto fix the problem. The forms I'd already created seemed to work fineafter re-creating the links.But then I got more advanced with my forms. I have it set up so thatfor certain entry fields, the combobox gets populated with values froma table (the description appears in the drop-down and the correspondingprimary key value gets populated in the table). I created a number offorms using this technique, entered data, and everything worked fine.Made a small schema change and it broke everything -- not the actualtable links, but the functionality for the drop-downs. My values nolonger appeared, and this was true for forms that accessed tables whoseschemas did not change.This is driving me nuts. Is there any way to keep my forms frombreaking each time I make a small schema change?Thanks.- Dana

Hi,
I worked on a project in ASP.NET using SQL server 2000 as the back end. Its a conversion application that I rewrote in ASP.NET using C#. I need to import the old data in Access db into SQL server 2000 and I have very little knowledge about doing it. The data in not a direct one -one transformation. There are considerable changes to the Database design and data types. Any help and suggestions wud be really helpful. Also, any article links wud be great.

We have a SQL Server 7.0 system in NT 4.0 environment. We upgraded our users to Access 2000 and started to work with this. Now we installed a new
server which is Windows 2000 based and the domain is different from
the SQL servers domain. We then installed Access 2000 on Windows 2000
to use with terminal server. But I noticed that there was a problem
with the program. I then looked at the program which was written on Access 2000 and saw that the tables and views can't be seen. The program runs but
I can't see the views and tables. Another thing is access disconects from SQL Server when I want to see the tables. So what can be the problem.
In one part there is an Access 2000 on Windows 2000 server. On the other part SQL Server 7.0 on Windows NT 4.0. And Access can't see the tables in SQL server.
I have a public mailbox that gets information mailed to it (in a pre-determined format).
Is there a way for that info to be put into a table in SQL Server without any user interaction (something running on the exchange server)?
I hope I've given enough info.
Thanks for any and all help!
