Hi all I have a question, In my view I have two tables linked together for the users, my issue is that I want them to see one record so they can get the proper total amount of records. The main table is reports and the child table is subjects. How do I make it so that they see one record from the reports table, because if there is more then one subject linked to a reports number which is the primary key, they will see more then one report number. Does that make sense??
However, the userelationship function does not override the active relationship between Operation & Advice and so the measure is limited to Advices directly filtered by the Operation table.
If I delete the relationship between Operation and Advice, then the measure works as expected i.e. Operation indirectly filters Operation Commodity which filters Advice.
I'm writing a workflow management application for my work, and its somewhat complicated, here's a general idea of how it works:
- Anything that a company does is defined by a workflow. - A workflow consists of tasks. - Some tasks in a workflow can't be started until other tasks have been completed. If task A can't be started until tasks B and C are finished, then task A depends on B and C.
You might imagine that a bank has a workflow for handling a house loan. Before a bank could sign a contract with an applicant, they'd need proof of house ownership, but before they could get proof of house ownership they need an applicant's proof of identity like a driver's license or military ID.
Here's an oversimplified visual:
Each arrow points to its dependency. Each task can have multiple dependencies.
The setup above is represented in the database by a Tasks and a Dependencies table. Tasks has an ID field, and Dependencies has a TaskID and DependencyID field which are both foreign keys to Tasks.ID.
Code:
[Tasks] ID Status Name -- ------ ---- 1 Done Start Processing Loan Application 2 Done Photocopy applicant's driver's license 3 NotDone Photocopy proof of house ownership 4 NotDone Get a copy of applicant's W-2 forms 5 NotDone Perform credit check on applicant 6 NotDone Sign loan contract
Tasks has a many-to-many relationship with itself.
Here's the hard part: - A task can't be started until all of its dependencies have been completed. - after a task is completed (meanings its status is marked "done"), I need to return a list of all the new tasks that are ready to be started.
When TaskID 2 is marked "Done", then TaskID 4 is ready to begin; however, TaskID 5 is not ready to begin since it depends on 2 and 3, and 3 hasn't been completed yet.
The requirements of the query are very simple, but the implementation is difficult.
I'll post a prelimenary solution in the next post:
Im really confused and need some help please from some of you clever people.
I know the basics of SQL but Ive no idea how to write a query to do this.
Basically, we have two tables, the first containing a list of people and the second containing two relationships to the person table. The first is the parent relationship and the second the child relationship. Each person may be related to one or more other people (e.g. father, son, brother, sister etc.). If you can imagine we have a few hundred people in the person going back a couple of hundred years.
Now Ive set the scene Im really trying to create a query that can navigate all the relationships from a set point (Person).
Ultimately I would like to (given a PersonID, navigate the full PERSON_ASSOCIATION table to find:
a. All people below the PersonID (if there are any) b. All people above the PersonID (if there are any)
For example, in the data below there is somebody called John Smith.
Going down the PERSON_ASSOCIATION table I would like to show:
John Smith has a brother called Andrew Jones who has a brother-in-law called Stephen Barnes
John Smith has a wife called Jane Wallace
John Smith has a daughter called Mary Joseph
What I am going round in circles on is the multiple relatationships, e.g. A is related to B who in turn is related to D who in turn is related to E therefore A is related to E.
PERSON ID NAME 1 John Smith 2 Andrew Jones 3 Jane Wallace 4 Steven Barnes 5 Mary Joseph 98 Me 99 Joanne
Can somebody please point me in the right direction by explaining how I can write some SQL that will navigate (and iterate through) all the PERSON and PERSON_ASSOCIATION tables.
Im sure there must be a straight forward way of doing this.
One final thing, if it helps, Im hoping to eventually end up with a stored procedure which I can basically pass in a PERSON_ID and it returns a list of all the relationships from that person.
Can Somebody please show me how to acheive this, using the order details in Northwinddatabase or any other good example. as much details as possible. Many Thanks!
How can I set a one-to-one relationship using the Management Studio Express and SQL Server 2005 Express tblClient, CleintID (PK) tblProcess, ClientID (FK)
Hello I have need to write a query that I can pass in a bunch of filter criteria, and return 1 result....it's just ALL of the criteria must be matched and a row returned: example: Transaction table: id, reference attribute table: attributeid, attribute transactionAttribute: attributeid, transactionid Example dat Attribute table contains: 1 Red, 2 Blue, 3 Green Transaction table contains: 1 one, 2 two, 3 three transactionAttribute contains: (1,1), (1,2), (1,3), (2,3), (3,1)
If I pass in Red, Blue, Green - I need to be returned "one" only If I pass in Red - I need to be returned "three" only If I pass in Red, Green - nothing should be returned as it doesn't EXACTLY match the filter criteria
If anyone's able to help that would be wonderful! Thanks, Paul

Can anyone provided insight on how to create a one-to-one relationship between SQL tables? Every time I try to link two tables that should be one-to-one, the link says one-to-many. How can I specify one-to-one when SQL Server automatically thinks it is a one-to-many? Thanks, Kellie
Hey, I know I'm asking a stupid question but I need to get a clear response please: why using One-to-One relationship instead of meging the 2 tables in only one? thanks.
I created 2 tables with one to one relationship. if I add a record intable A, how does table B record get created? Does SQL do thisautomatically because it is one to one relationship? or do I need tocreate a trigger? if i need a trigger, how do I get the ID of newrecord to create the same ID in table B?thanks for any help.Joe Klein
Hi,Do you guys know what's wrong with a one-to-one relationship?The reason I want to make it like this is that at the very end of the chain,the set of keys is huge. I want to limit the number of columns to be thekey. i.e. the [company] table has 1 column as the key. The [employee]table will have 2 columns as the key.e,g,If I add a [sale] table to the [company]-[employee] relationship, the thirdtablewill have 3 columns as the key -- "company id", "employee id", and "saleid".(e.g.)I have a company with many employees and computers. But instead of classifyall these, I just want to call all these as an entity. A company is anentity. An employee is just another entity. etc.So, instead of a one-to-many:[company]---*[employee]---*[sale]||*[computer]I make it one-to-one.[entity]---*[entity]If I want to know the name and address of the entity "employee", I will havea 1-to-1 table [employee] to look up the information for this employeeentity.[entity]---*[entity]||[company]||[employee]||[computer]||[sale]--[color=blue]> There is no answer.> There has not been an answer.> There will not be an answer.> That IS the answer!> And I am screwed.> Deadline was due yesterday.>> There is no point to life.> THAT IS THE POINT.> And we are screwed.> We will run out of oil soon.[/color]
How do I create a one to one relationship in a SQL2005 Express database? The foreign key needs to be the same as the primary key so it can't just increment to the next number.
Hi. I get this error when i try to create a relationship in a db diagram (sql 2005) "'tblActivedir' table saved successfully 'tblClient' table - Unable to create relationship 'FK_tblClient_tblActivedir1'. Introducing FOREIGN KEY constraint 'FK_tblClient_tblActivedir1' on table 'tblClient' may cause cycles or multiple cascade paths. Specify ON DELETE NO ACTION or ON UPDATE NO ACTION, or modify other FOREIGN KEY constraints. Could not create constraint. See previous errors."
What i have is 2 tables. 1 named client 1 named activedir
In the client table the columns i want to bind with activedirtable are FR1 and DC1 I want to bind them in the ID of the activedir table (both, in different fk relationships) so that they get the id of activedir. Fr1 has an fk relationship with activedir (pk is activedir' id) and DC1 exactly the same in another fk. So i want both columns to comunicate with activedir. If p.e. activedir has 3 elements (a,b,c) when i delete element a then werever FR1 or DC1 have this element(binded to it's id) then the element will also be deleted (id of the element) from both FR1 and DC1 I don't want to set Delete and Update action to none because i want the element changed or deleted from activedir, to do the same on Fr1 or DC1 or both. Any help? Thanks.
I am trying to create a 1:1 relationship, but not primary key to primary key. In table 1 I have a uniqueidentifier as a primary key. In table 2 I have an int as the primary key and a column that takes the uniqueidentifier from table 1. Everytime I drag and drop the relationship line and link table 1 to table 2 it creates a 1:N relationship: ie. tbl1.primarykey links to tbl2.column2. So I'm not linking primary key to primary key however I still want a 1:1 relationship.
SQLServer 2005 - I have two tables. One has a field defined as a Primary Unique Key. The other table has the same field, but the Index is defined as non-Unique, non-clustered. There is no primary key defined on the second table. I want to set up a one-to-many relationship between the two, but am not allowed.
This should be simple. What am I doing incorrectly?

I have a fact table with 2 fields : "Dim Code 1" and "Dim Code 2" that I want to link with a Dim table. I don't want to create two dimensions Dim1 and Dim2 but only one dimension with something like :
Shirt shirt_id client_id meas_arm meas_neck meas_shoulder color_code description My question Is it possible to have a relationship linking one single table to other several one. For example i wanted to relate the field client_id from table client which is the primary to tables shirt,trousers and smoking with the client_id field which is the foreign key ?
Hi there everyone, this is my first post so go easy on me :) Basically I am trying to get my database to copy the value in the UserId (unique identifier field) from the aspnet_Users table to a foreign key UserId in a table called userclassset. I have made this field the same datatype and created a relationship between the two. Unfortunately, when I add a user using the ASP.Net configuration tool it does not automatically copy this value into my own custom table. I have noticed it is however automatically copied into the aspnet_Membership table. Any pointers on how to solve this would be great! Thanks :)
Hi, how can i make optional relationship? for example: In table A, there is column 1, column 2, column3. In table B, there is column 4, column 5 and column 6. column 1 and column 2 are primary keys for table A and table B. The relationships between table A and table B are column 2 and column 5; column3 and column 6. but optional (ie. when data exists in column 2, then column3 is null) how can i set the relationship? because one of the columns data is null each time, error always occurs.
Hello, I created some SQL 2005 tables using Microsoft SQL Server Management Studio. I need to get the script code of those tables. I was able to do that by right clicking over each table. But how can I get the code for the relationships between the tables? Can't I create relationships between two tables by using T-SQL? Thanks, Miguel
When I try to insert a record on my DB (SQL 2005 Express) I get a constraint error. This is my table setup which has been simplified to expose the problem I have: Categories TABLEint CatId PKvarchar CatName : Items TABLEint ItemId PKvarchar ItemName : X_Items_Categoriesint CatIdint ItemId So basically I have a one-to-many relationship between Items and Categories, in other words each item is associated to one or more categories and this association is done via the X_Items_Categories cross table. On this cross table I set two constraints:
The CatId of each entry in the cross table (X_Items_Categories) must exist in the Category table, and
Hi there, I just set up my AppData and i'm trying to connect the Membership to a tbl_Profile that i created.I notice there's an application_id and a user_id which are uniqueidentifiers. I've been trying create a relationship to tbl_Profile's user_id column but it won't let me saying it's not compatible. Am i suppose to set tbl_Profile's user_id column to int or uniqueidentifier? I've tried both and it won't let me... THanks!
HiI have 2 tables one is called QuickLinks and another called QuickLinkItemsQuickLinksQuickLinkID<PK> UserID QuickLinkName-------------------------- ----------- ------------------------1 111-111-111-111 QuickLink12 111-111-111-111 QuickLink23 222-222-222-222 QuickLink1 QuickLinkItemsQuickLinkID <FK> CharacterName CharacterImagePath---------------------- ------------------------------- ---------------------------------------- 1 a path11 b path22 d path32 e path43 a path14 b path 2 So thats how I see the data will look like in both of these tables the problem however I don't know how to write this into Ado.net code. Like I have made a PK to FK relationship on QuickLinkID(through the relationship builder thing). I am just not sure how to I do this. For the sake of an example say you have 5 text boxes 2 text boxes for inserting the character names and 2 text boxes for inserting the CharacterImagePath. Then one for the Name of the QuickLink. So how would this be done? Like if it was one table it would be just some Insert commands. Like if this was all one table I would first get the userID from the asp membership table then grab all the values from the textBoxes and insert them where they go to and the QuickLinkID would get filled automatically. The thing that throws me off is the QuickLinkID since it needs to be the same ID as in the QuickLink table. So do I have to first insert some values into the QuickLink table then do a select on it and grab the ID then finally continue with the inserts Into the QuickLinkItems table? Or do I have to join these tables together?Thanks
hi there, after a lot of fussing about i found it would be a lot easier to use an SQLDS and a gridview to display my data rather than code it. However i cant for the life of me work out how to replace some of the numbers (IDs) with their accompanying names. so i have a QTY which is an INT and a Location1 which is an INT in tbl_stock_location and in tbl_locations i have the appropiate 1 = shop etc this is what i came up with for my string SELECT tbl_stock_part_multi_location.stock_part_multi_location_ID, tbl_stock_part_multi_location.stock_ID, tbl_stock_part_multi_location.Description, tbl_stock_part_multi_location.Qty1, tbl_stock_part_multi_location.Location1, tbl_stock_part_multi_location.Qty2, tbl_stock_part_multi_location.Location2, tbl_stock_part_multi_location.Qty3, tbl_stock_part_multi_location.Location3, tbl_stock_part_multi_location.Qty4, tbl_stock_part_multi_location.Location4, tbl_stock_part_multi_location.Qty5, tbl_stock_part_multi_location.Location5 FROM tbl_stock_part_multi_location INNER JOIN tbl_location ON tbl_stock_part_multi_location.Location1 = tbl_location.Location_ID AND tbl_stock_part_multi_location.Location2 = tbl_location.Location_ID AND tbl_stock_part_multi_location.Location3 = tbl_location.Location_ID AND tbl_stock_part_multi_location.Location4 = tbl_location.Location_ID AND tbl_stock_part_multi_location.Location5 = tbl_location.Location_ID WHERE (tbl_stock_part_multi_location.stock_ID = @stock_ID)"
I used the query builder for this but it just dosnt seem to work and throws an error at me. Any help would be great!
