thanks alot.
Is there a fast way to see, which relations a table has for his PK?

is it posible to add relations in sql compact databases (.sdf) ?
I tried in server explorer (in orcas) and there is no option for relations. Also .sdf file cannot be opened in SQL Server Express Management Studio SP2 because is version 3.5.
Hi There,Im trying to display a list of results and have extra information pulled from another table. Please read on as this isnt what you think, just hard to explain but I will try.In Table 1 I have a set of Orders, example data below.Order 1, Line 1Order 1, Line 2Order 1, Line 3Now I have another table to record what lines a user would like to monitor, for this example the user will monitor these lines.Line 1Line 2but not Line 3I need to display a single grid view using the least amount of queries possible to diplay the following resultOrder 1, Line 1, MonitoredOrder 1, Line 2, MonitoredOrder 1, Line 3, NOT MonitoredI have tried viewed, but with the relationships it only displayes what is avialable in both tables, I have also thought about using a DataSet relationship with two queries through the code, but am really wondering if anybody knows of a simple and low overhead way of producing this result? Mayby stored procedures?Kind Regards,Gareth
View 2 Replies View RelatedI'm looking for some input about how I should setup my database tables. Here's the setup - There are several Report Forms that users can fill out and each one has its own table (I'll use Report1 and Report2 for examples). There are several other tables that relate to these Report tables, for example, a table named Pictures. If a user is filling out Report1 or 2, they could add a picture to it. The picture information is stored in the Picture table, along with the ReportID of the report it belongs to.
Report1 (table)intReportID (pk)vcFirstNameetc...Report2 (table)intReportID (pk)vcFirstNameetc...Pictures (table)intPictureID (pk)intReportID (fk - to match ReportID in appropriate Report table - not being allowed...)vcFilePathetc...
Right now, I've two relationships setup for the pictures table - one with the picture table ReportID as a FK to the Report1 table's ReportID PK, and another setup the same way, but for Report2.It's not letting me do this because it's looking for a matching ReportID in both the Report1 and Report2 tables for each entry in the Pictures table. A match will only ever exist for one or the other, never both.
In addition to Pictures, I have about 9 other tables that work the same way. I also have about 7 Report tables total. I'd really like to set something up so if I delete a record from a report table, it will delete all matching entries from the other tables. Does anyone know how I can go about setting this up?
Thanks very much!

I have just made a database with 3 tables, they are now connectet with relationships.
My problem is when I write my select statement:
select * from table1 a, table2 b where a.ID=2.
I will get all the ´records from both the tables, I just want One record. Then I addes some too my select statement so it now looks like this:
select * from table1 a, table b where a.ID=2 AND a.No=b.No
Now I got the right result, but if this is the only way to do it, there is no recent to make all the relations i the DB between the tables.
Thank You... Jonas

I want to join tables above in only one query.
I tried something I couldn't.
there are 5 users in TBL1
TBL2 is for their web sites records.
But while tom,alice,alex and carl have web site,Melissa hasn't.
I want to print like below
Code:
Tom http://www.Tom.com
Alice http://www.Alice.com
Alex http://www.Alex.com
Melissa

my tests, although users who have web site were printed, Melissa wasn't printed.
Although she hasnot a website, I want to get her , too.
Hi,
I build a local cube from a relation database. In the database there are 1:n relations.
Is there a way to handle 1:n relations?
For example:
I have a table LOGGEDFLAW and a table LOGGEDREASON with a 1:n relation between them. We create a select statement of these tables and as an result we get duplicate records of LOGGEDFLAW each time more than 1 record of LOGGEDREASON are associated to 1 record of LOGGEDFLAW - this is the standard result I get with an relational JOIN operation. Now I want to count the LOGGEDFLAWs without the duplicates generated by the 1:n relationship.
Best regards,
Thorsten

View 1 Replies View Relatedhello,
i started making my database some time ago, and therewith i maked some relations between my tables
at the beginning, at Tables, at the UserId row, i had uniqueidentifier. and because i had some difficulties when trying to get the username who corresponds with that uniqueidentifiers i've discarded that and replacing the uniqueidentifier with varchar(255) where i am writing dirrectcly User.Identity.Name.
Because of that, i had to delete some of the tables relations, because i can make relations only by unique variables (witch in fact are unique but database can't know that)
What i should do now? remake the tables with UserId as uniqueidentifer or i should let it so without no relations between them? (witch i don't think is good)
thanks
i want to write program that will return
the relations between the tables and its type (one to many,.....etc)
any help

Hi,
I have a doubt, can anyone please clarify me.
I have created the following table,
create table z
(
eno int,
deptno char(2),
ename varchar(5),
constraint pk_eno_deptno primary Key(eno,deptno)
)
and I tried to establish a foreign key based on the above defined table. It's giving error,
create table z_dup
(
eno int FOREIGN KEY REFERENCES z(eno),
deptno char(2)
)
go
Error:-
*****
There are no primary or candidate keys in the referenced table 'z' that match the referencing column list in the foreign key 'FK__z_dup__eno__18CE1BA6'.Could not create constraint. See previous errors.
Even I tried to create a foreign key like the following,
create table z_dup
(
eno int FOREIGN KEY REFERENCES z(eno,deptno),
deptno char(2)
)
go
Error:-
********
More than one key specified in column level FOREIGN KEY constraint, table 'z_dup'.
Can anyone please help me to create a foreign key relation with the base table.
tks in advance,

I have to synchronize 2 databases hourly but am having difficulty maintaining foreign key relations. These tables use auto-increment columns as primary keys, with child records in other tables related with foreign keys. I can't change the way the local software uses primary or foreign keys as it is hardcoded in the local app. (microsoft retail management system)..(however the web-remote app is easily customized). I am using CDB synchronizer to sync the two databases because the remote one is mysql.
Example tables layout:
Items table has auto-increment primary key 'id'
TransactionEntry table has its own auto-increment primary key 'id' and a foreign key 'item_id'
Example of how remote and local database foreign key relations are incorrect after sync using CDB synchronizer:
8:00am -first installation of database-'item' tables auto-increment 'id' columns match with id last record value of '6'
locally the following products are added:
11001 short sleeve t---gets added with primary key in 'item' table 'id' of '7'
11002 long sleeve t----gets added with primary key in 'item' table 'id' '8'
remotely the following products are added:
21001 hipster jeans- --gets added with primary key in 'item' table 'id' of '7'
31001 overalls---gets added with primary key in 'item' table 'id' '8'
remotely someone orders 21001..so TransactionEntry table records sale of "item_id" of '7', but after synch with our local server,
product with "item_id" of '7' is "short sleeve t".
9:00 -synch takes place...item_id foreign key isn't accurate because of independent auto-increment values..
whenever a product is ordered, the TransactionEntry table will record the product's ID column thats available in it's own local copy... after synch, the 'item_id' field will not match the 'Item' table id field and the data about the transaction's product is lost.
I have read of solutions involving staging/temporary tables to cascade update foreign keys before synching into main database, but hopefully there is a more elegant solution for this. If this is only way, will it be reliable? foreign key mix-match seems like could cause havoc.
Hi all,
I have a big problem. I have many tables with constraints, with foreign keys. I need to create a ordered list of tables, on the top must be the basic table what has no parents, then the second level tables (those depends on the first level) the the names of third level etc.
for example:
Table A[id]
Table B[id, idc]
Table C[id, ida]
Table D[id, ida]
Table E[id, idc]
I tried it by using information_scheme but I was unsuccesfull.
The result should be:
A
C
D
B
E

i've a database where relations are hold in a special way which the projectleaders think of as "performant and uncomplicated" but which is veryquestionable to me:------------------------------------------------Table [Attributes]Fields [AttributeID] and [AttributeText]Table [Objects]Fields object stuff.... and [AttributeIDs] (varchar with 0-20 ids usually)in AttributeIDs there is a backslash separted list of Attribute-IDs like'3412278'so to get 20 object with a special attribute (which we need often) we doSELECT TOP 20 *FROM ObjectsINNER JOIN AttributesON (Objects.AttributeIDs LIKE ('%' + (CAST AttributeID AS varchar) + '\%'))ORDER BY ObjectTextps: to store data we need for communication we include a dozen of fields in*every* table and its content makes about 100 bytes/record------------------------------------------------i would do this stuff with a table to store the object/attributecorrelations.could someone tell me if that stuff makes any sense to an expert and how tovaluate it in regard of performance(we have big customers where that *is* anissue), design, scalability, pragmatism and sense ;)thanks in advance,ViperDK

I've been trying to export a whole database from one server to another (connected through a local network) but the keys always get lost: when I open the diagrame I can actually see them just before the tables names appear. I've tried inserting the primary keys for each table manually with the export wizard, which took me some time, but no relations were exported. Any way of doing this automatically?

HiI have to make export of SQL Server Database to MS Access and I havedone it with the tables but now I need to transfer(export) therelations, keys and indexes. Can any1 tell me how to read relations,keysand indexes from SQL Server and convert them to MS Access.(it seams thatfor creation of indexes in MS Access ADOX is the only way but ADOXcannot read all information about keys,indexes from SQL Server.)All I can see is that I have to use SQLDMO to enumarate allrealtion/keys/indexes from SQL Server database and use ADOX to createthis relations/keys/indexes in MS Access database, but I don't knowexact matching attributs of relations/keys/indexes from SQL to Access.Thanks
View 3 Replies View RelatedSuppose I have a table with relations (REL). In this table there are relations between parent en child, so the columns are: Rel_Id, parent_Id, child_Id. Example:
1, A, B
2, A, C
3, A, D
4, B, E
5, C, F
6, G, H
7, G, I
8, H, J
I need a query which returns all relations from REL that are in the same tree as the input unit.
In the example, giving D as input unit, it should return relations 1, 2, 3, 4 and 5, because A, B, C, E and F are (in)directly related to D and belong therefore to the same tree.
Giving H as input, it should return relations 6, 7 and 8.
(with a tree, I mean that a parent can have 0, 1 or more children and a child belongs at most one parent.)
Thanks for your help in advance!
I am having a requirement as below. I am having a Emp_Dim dimension table which is having a Manager_Key which is dependent on again on the Emp_Key. Based on the designation I have to create a Hierarchy. I have to create a Hierarchy with 10 levels according to the Designation.
While extracting data I am giving a particular Area manager id in Emp_Key I should get the accumulated data (His and the employees working under him as well). So it's like my MDX query should be like this if I am giving any emp_key then I need all the business done by under him.
My doubt is how I can establish the relations between the different levels in my Hierarchy. I am pretty new to SSAS.
hi! I've been using sql server for a while but until recently have kept things pretty simple. now I'm trying to expand my horizons by trying to tackle some more complex applications, and one I'm really struggling with is nested relations. I hope this is in the right forum; if it is not, please feel free to move it, thank you!
here is my problem: I'm desigining a simple "Downloads" page in asp.net, and I have two tables set up. One is Downloads and the other is DownloadCategories. here is a simplified layout of the tables:
Downloads:
ID PK
Title
Description
CatID FK
DownloadCategories
ID PK
Name
Description
ParentID FK
basically CatID in downloads is a foreign key to the ID in downloadcategories, and ParentID is a foreign key to the ID in the same table, downloadcategories. This is set up because I want to support an infinite number of categories, each being able to support their own subcategories, which can go deeper into more subcats, and so on...
the problem is that I can't seem to get them to fill into the dataset I've created in vs 2005's designer. I have a procedure SelectAll which retrieves all rows, and SelectMain which retrieves only the topmost categories (where ParentID=Null). If I fill the datatable with SelectMain, I don't get any of the child categories, and if I call SelectAll, I get just a single table with all the rows, but no relations.
I have defined a relation in the datatable that mirrors that of the database, but no matter what I try, I cannot get it to show the relationship in the datatable when I fill it. am I doing something wrong? this is kind of how I have it setup:
dataset with Downloads and Categories datatables, relations from Categories to Downloads, and from Categories to Categories. I have the two queries added to the table adapter, and I call the SelectAll query to fill it, but all it does is fill the table with rows; it doesn't create any relations.
I hope this explanation of my problem makes sense. as I said I'm still very new to this complex stuff, and I'm hoping to get my head around it soon, because I really need the functionality (not to mention the skills!) so if you can take a moment to go over what I've explained and point out where my flaw might be, I would really appreciate it!!
if you need any more information to help, please let me know and i'll get right back to you. thanks a bunch!

Hi all,
In my project i will have the data in a collection of objects, I need to update series of tables with foreign key relations
Right now my code looks like this
foreach(object obj in Objects){
int accountId=Account.Insert(obj.accountOpenDate,obj.accountName);//this will update the accounts table and returns account id which is a Identity column in Acccounts table
int DebtId=Debt.Insert(accountd,obj.debtamount,obj.debtbalance); this will update the Debts table and returns DebtId
///series of tables like above but all the relevant data comes from obj and in the Insert Methods i am using stored procedures to Insert the data into table
}
The no of objects varies from 1000 to 1 milliion,, with this approach its taking more time to update all the data. Please let me know if any alternative procedure to handle this kind of scenario.

Why terms are not being corrected on a partial match? I thought this was the point of term based relation rules.
I am testing in an email address (nvarchar) field?
E.g. trying to correct @@ to @ and .con to .com (just to test)
And everything passes.
If I test with an entire value, the field is corrected.
E.g. 605688878@@qq.com corrects to 605688878@qq.com if I enter those exact values as term based relations.
