Table FACT1 is located on SERVER1 & Database - DBS1 (SQL Server 2000) with a column 'Date_fk'
Table DIM1 is located on SERVER2 & Database - DBS2 (SQL Server 2005) with a column 'Date_pk'.
I m trying to create a foreign key relation ship as follows:
ALTER TABLE [dbo].[FACT1] WITH CHECK ADD
CONSTRAINT [FK_Issue] FOREIGN KEY([Date_fk])
REFERENCES [SERVER2].[DBS2].[DIM1] ([Date_pk])
but it throws the foll. error
Foreign key 'FK_Issue' references invalid table 'SERVER2.DBS2.DIM1'.
Hi, I don't know if this is possible, i believe not, so I'm here to ask the experts if is possible to have a foreign key constraint that references the key of one of two tables. Like this: I have 3 tables: TABLE X, TABLE A and TABLE B Is it possible to the FK on TABLE X refernce the PK of TABLE A OR TABLE B? If yes, how can I do this? If not, I need to have a fourth table, so TABLE X references TABLE A and TABLE Y references TABLE B. Thanks!
The following SQL statements give me an error on the last line:
CREATE TABLE Employees (id int PRIMARY KEY NOT NULL, name nvarchar(50)); CREATE TABLE RandomTable (uniq int PRIMARY KEY NOT NULL, empid1 int NOT NULL, empid2 int NOT NULL); ALTER TABLE RandomTable ADD CONSTRAINT RandomTable_FKey_1 FOREIGN KEY (empid1) REFERENCES Employees (id) ON DELETE CASCADE; ALTER TABLE RandomTable ADD CONSTRAINT RandomTable_FKey_2 FOREIGN KEY (empid2) REFERENCES Employees (id) ON DELETE CASCADE;
The error is:
"The referential relationship will result in a cyclical reference that is not allowed."
Um...how is this cyclical? Is it because I have multiple cascade paths? If so, how do I go about doing the same thing?
I'm trying to create a local copy of a popular CRM database calledSalesforce.com. Many of the tables in the DB have FOREIGN KEYreferences that I want to preserve, but I've run into a chicken and eggproblem. Table "A" has a reference to table "B," and table "B" has areference to table "A." So I can't CREATE one until the other exists.Is there a way to disable these checks until I've created all theschema?Here's what I see (error first, then SQL that caused it):Server: Msg 1767, Level 16, State 1, Line 1Foreign key 'FK__UserRole__LastMo__48CFD27E' references invalid table'User'.Server: Msg 1750, Level 16, State 1, Line 1Could not create constraint.

I am using vs 2010 to write my dtsx import scripts.I use a script component as a source to create a flat file destination file.Everything have been working fine,but then my development machine crashed and we have to install everything again.Now when i use the execute package utility to test my scripts i get the following error:
Error system.NullReferenceException: Object refrence not set to an instance reference.
In PreExecute section TextReader = new system.io.streamreader(" file name") In the CreateNewOutputRows: dim nextLine as string nextLine = textReader.ReadLine
[code]...
is there something which i did not install or what can be the error?

when l run the cursor l get the error Server: Msg 207, Level 16, State 3, Line 15 Invalid column name 'Loan_No'. . If l reference it as Set @LoanNo = LoanTable.Loan_No l get the error

Can anyone see why I would get the 'Object Referenece not set to an instance of an object error in the following code? It happens on this line: MyAdapter.SelectCommand = New SqlCommand(SelectStatement, MyConnection) 'Populate the text boxes from database for alumni fields.

I am access SQL 7 via ADO in some ASP pages. My database objects were created under a user name aliased to the dbo. As a result, when I have my client logon to make a connection, I have to preface all my object references with the name of the owner, i.e., Select * from mydboname.people . Is there a way to avoid having to prefix all my transact sql statements with the owner?
I have two tables that are reference to each other by foreign key, now I would like to alter the table so the it doesn't reference each other any more. What is the syntax to alter a table so that the fk field doesn't reference a table anymore. Thanks in advance for the help.
As I posted earlier, I am relatively new to TSQL. I have been given a few books: O'Reilly SQL on SQL Server 2005 O'Reilly SQL in a Nutshell Mastering SQL Server 2005 - Sybex Beginning SQL Server 2005 Programming - Wrox
I have a copy of SQL2005 Developers Edition on a development server. So I think I have some decent tools at my disposal.
I was wondering if there are any other sites or forums that might be suggested for learning SQL programming? Right now, I am just making stuff up and following examples in books, etc. I would like to find a site where there are beginner level projects for no other purpose than educational. Something where I can get more hands on of the design and programming aspects. Just to practice.
CREATE TABLE s (sno VARCHAR(5) NOT NULL PRIMARY KEY, name VARCHAR(16), city VARCHAR(16) )
CREATE TABLE p (pno VARCHAR(5) NOT NULL PRIMARY KEY, descr VARCHAR(16), color VARCHAR(8) )
CREATE TABLE sp (sno VARCHAR(5) NOT NULL REFERENCES s, pno VARCHAR(5) NOT NULL REFERENCES p, qty INT CHECK (qty>=0), PRIMARY KEY (sno, pno) )
when i run this query i get an error saying:
Column 's.sno' is not the same length as referencing column 'sp.sno' in foreign key 'FK__sp__sno__5EBF139D'. Columns participating in a foreign key relationship must be defined with the same length.
Now i have a reauirement to build a stored proc in which all the transactions starting from one transaction like, if i want to know the chain for item no 2 it shall give the following result:
24 43 37
if i want to know the chain for item no 3 then it shall give following 37
if i want to know the chain for item no 1 then it shall give following 12 24 43 37

Hello. I'm getting an error - "Object reference not set to an instance of an object" when running an SSRS report with graphs. It only happens when the returned dataset is empty (based on parameters set by the user, it is possible to return no rows). I've tried using the NoRows property (I entered "No Data" in the property box), but I still get the same error. Is there another way to account for an empty dataset in charts?
I would like to use a custom build class library written in C# inside of the vb script. Does anyone know how to add the reference to the scriptComponent project once you open script through design script button?
Given a UDT, is there any way to get a reference to the table where the specific instance is running ?
IE: Let's suppose we have defined a UDT named UDTPoint; now we define two tables: ATable & BTable, wich both have one column that is defined as UDTPoint.
When an insert/update/delete operation on ATable or BTable occurs, the UDTPoint class needs to verify in which context it is running (ATable or BTable) before doing operations on data.
Hi, I wanted to add a reference to an assembly in my report (not a DLL, but an EXE). As I see there is no option to select an assembly which is an EXE. Firstly, is it possible to add a reference to an EXE (I guess not)? Secondly, If no, why is it not possible?
The table above is my users table. It allows for a user to be at multiple sites or multiple locations within a single site or multiple sites. Would it be wise to use a auto incrementing primary key instead of the 3 column composite key? The reason I ask is because if I am referencing this SU table (which I will be a lot), a lot more data would be replicated to the tables which have the foreign key to this table, right? But if I used a single incrementing column as the primary key, only a small integer would be used as the foreign key, saving space?Does this make sense?
I have a .NET assembly that I need to reference and use within my SSIS script task. The only way I can acheive this is to strongly name my assembly and put it in the GAC. This is not possible as my assembly is already in production and uses other 3rd party assemblies that would also need to be registered in the GAC. As a workaround, I have created a .Net console application that references my assembly, that call from a SSIS Process Task. Does anyone know of another way I could use my .NET assembly within my SSIS package? Any help appreciated. Regards, Paul.
Please help as I've no idea what to try next! I had a 2003 project designed by someone else. I upgraded it to 2005 using the conversion wizard. Now it all works find within vs2005, I deploy it to a location else where on my pc and create a virtaul directory and map it so that I'm using IIS. This all works fine. As soon as I move it to a virtual machine (windows 2k server SP4 IIS5) I get object reference not set to an instance, basically what I can determine is my sqlconnection fails when it is opened.
