The INSERT statement conflicted with the FOREIGN KEY constraint "FK_tblLinks_tblWebSite".

  

How does this happen? the tblLinks doesn't even have a column called websiteID.  websiteID is the primary key of the table tblwebsite. LinkID is the primary key of tblLinks. There is not LinkID column in tblwebsite.

The INSERT statement conflicted with the FOREIGN KEY constraint "FK_tblLinks_tblWebSite". The conflict occurred in database "Linkexchanger", table "dbo.tblWebSite", column 'WebSiteID'. The statement has been terminated.

 

So how does this happen? How do I terminate the foreign key relationship? I understand I can add this to my Insert stored procedure:

ALTER TABLE Links
DROP CONSTRAINT FK_tblLinks_tblWebSite

but that stored procedure is used for other functions in my website, and I don't know if doing that is a good idea. Is there a way to relax the constraints for the purpose of this function here?  I'm taking data from a backup links table and trying to write a new row in the links table.


INSERT statement conflicted with COLUMN FOREIGN KEY constraint...

  

Hi there,

I have a stored procedure which i pass a number of parameters into. One of these parameters is staffNo (only passed this in because i couldn't execute the query without it). The thing is this field can be Null, but when trying to pass null into it it comes up with an Foreign Key conflict. staffNo is a foreign key within the table i'm inserting the data into.

This is the error i get:

"INSERT statement conflicted with COLUMN FOREIGN KEY constraint 'PropStaffFK'. The conflict occurred in database 'DewMountain', table 'TblStaff', column 'staffNo'. The statement has been terminated. The 'PropertyAdvert' procedure attempted to return a status of NULL, which is not allowed. A status of 0 will be returned instead. "

 

Does anyone know of away around this? how to pass a null value to the stored procedure without it causing this error.

Thank you

Melanie

SQL DIAGOSITC MANAGER tools capture "SELECT *" statement while ALTER / ADD CHECK CONSTRAINT is execu

  
Hello  ,   I exectuted the code(alter/add with check)  below in SSMS . My_table has 200 millions records . While running the alter/add with check query  the server crashed and the “SQL DIAGOSITC MANAGER” which run on the top of sql serever alert the DBA that select * from my_table was obtained from the last command issued by the user using a DBCC command.      Where does the select * from my_table comes from ? I didn’t excuted select * from my_table at all .   After the sql serever re started I was able to run the command below with out any problem. I checked the SQL PROFILER for the trace there is no “select * from my_table” .   So again where this select * from my_table comes from ?   Here is my initial query ----------------------------------------------------------------- ALTER TABLE [Dbo].my_table WITH CHECK ADD  CONSTRAINT [FK_key1] FOREIGN KEY([Key1]) REFERENCES [Dbo].[Dim_table1] ([Key1]) GO   ALTER TABLE [Dbo].my_table CHECK CONSTRAINT [FK_key1] GO   ALTER TABLE [Dbo].my_table WITH CHECK ADD  CONSTRAINT [FK_key2] FOREIGN KEY([key2]) REFERENCES [Dbo].[Dim_table2] ([key2]) GO   ALTER TABLE [Dbo].my_table CHECK CONSTRAINT [FK_key2] GO   ALTER TABLE [Dbo].my_table WITH CHECK ADD  CONSTRAINT [FK_key3] FOREIGN KEY([d], [c], [r], [g]) REFERENCES [Dbo].my

The DELETE statement conflicted with the REFERENCE constraint "FK_tblAdvanceLink_tblLink

  

I"m using table adapters here. I tried to use the following in my table adapter:

ALTER TABLE tblAdvanceLInk

DROP FOREIGN KEY FK_tblAdvanceLink_tblLink

DELETE FROM [tblAdvanceLink] WHERE WebsiteID=@WebsiteID 

 

The DELETE statement conflicted with the REFERENCE constraint "FK_tblAdvanceLink_tblLink". The conflict occurred in database "LinkExchanger", table "dbo.tblAdvanceLink", column 'LinkID'.
The statement has been terminated

I get the same problem every time. So I read you could do this in a sql query. Why doesn't this work in my tableadapter? Do I have this in the right place?  Do I also put this into the other table? (tblLInk)

Isn't there a way to just relax ALL constraints so I can delete some rows? I'm deleting rows from both tables which have the corresponding websiteID


SQL Server 2008 - Alter Table Switch Statement Fails Where Partition Key Defined as a Persisted Comp

  

Here's a very annoying and poorly (or undocumented) issue in SQL Server 2008 Ent. Ed. post-SP1, CU8:

When creating a table with a persisted computed column as the clustered primary and partitioning key (see below), where the computation includes a call to CONVERT, watch out for the representation of this calculation on sys.computed_columns.  The query parser will modify the definition at table creation to insert a default style parameter of "(0)", if no other style is specified.  If the original definition did not include any style parameter and you later attempt to programmatically recreate the table using the stored definition contained on sys.computed_columns, the query optimizer will throw an error when you then attempt to switch partitions from the original table into the new programmatically created table, as follows:

Msg 4966, Level 16, State 1, Line 72

ALTER TABLE SWITCH statement failed. Computed column '%' defined as '%' in table %' is different from the same column in table %' defined as '%'.

This is so, eventhough the two definitions are completely functionally equivalent, considering the default value of the style parameter.  This can cause a lot of headaches, because correcting the problem requires dropping and rebuilding the computed column with a definition that include

The DELETE statement conflicted with the REFERENCE constraint. The conflict occurred in database.

  

Hello,

I am getting the following error 

The DELETE statement conflicted with the REFERENCE constraint "FK_Person_Country_CountryID_CountryID".
The statement has been terminated.

I know what the problem is, but can anyone help me in catching this exception in the best possible way?

I do not want the user to delete the country if there are any FK contrains. Or a better way will be to ask the user if they want to delete the records referencing this "Country".

int countryID = Convert.ToInt32(gvCountry.DataKeys[e.RowIndex].Value);
        db.DeleteCountry(1, 1, countryID);
        db.SubmitChanges();
        gvCountry.EditIndex = -1;
        BindData();


**i am using linq to sql

Thank you.

Ambiguous MSDN help on ALTER TABLE ... SWITCH statement

  
This page on MSDN contains a paragraph that I believe is ridiculously ambiguous:
"Source and target tables must share the same filegroup . The source and the target table of the ALTER TABLE...SWITCH statement must reside in the same filegroup , and their large-value columns must be stored in the same filegroup . Any corresponding indexes, index partitions, or indexed view partitions must also reside in the same filegroup . However, the filegroup can be different from that of the corresponding tables or other corresponding indexes."

What other "corresponding" tables or indexes can there be involved in the ALTER TABLE ... SWITCH statement? Why does this paragraph mention tables and indexes sharing the same filegroup when partitions of each of them can reside on different filegroups?

Can someone please enlighten me on the meaning of this paragraph?

Saving primary key constraint when creating new table using SELECT INTO statement - SQL Server 2008

  

Using SQL Server 2008:

We have a main database - MAIN.   For monthly data extracts, I create new tables with relevant data in another database called EXTRACT.

I use SELECT INTO statements to create the tables in the EXTRACT schema.  How do I preserve the primary key constraints in the EXTRACT tables?  Do I need to write separate queries to set them?

SELECT statement to return NULL by matching data from another table.

  
Hi,I am fairly new at SQL and I have been struggling for days now trying to find an answer to my problem and i have come to the point where i have run out of ideas and about to give up. I'm hoping someone can put me in the correct path. The problem I have 3 table Table 1 Department" has the following columns: REF, NAME Table 2  "Department_Collection" has the following columns: REF, DEPARTMENT_REF, MANAGER_REF, STORE_REF, ACTIVE Table 3 Store" has the following columns: REF, NAME, STORE_ID  What i am trying to do is to take all the rows in the Department table and get a matching row (DEPARTMENT.NAME, DEPARTMENT_COLLECTION.REF) from the Department_Collection table, if it does not match any then still display DEPARTMENT.NAME but mark DEPARTMENT_COLLECTION.REF as null. I have tried the following select statement but it seem to remove all null values when supplied with a 'storename' SELECT DEPARTMENT.NAME, DEPARTMENT_COLLECTION.REF FROM DEPARTMENT_COLLECTION right outer join DEPARTMENT on DEPARTMENT_COLLECTION.DEPARTMENT_REF = DEPARTMENT.REF left outer join STORE on DEPARTMENT_COLLECTION.STORE_REF = STORE.REF where STORE.NAME = 'storename' order by DEPARTMENT.NAME   Any help will be greatly appreciated. Thanks

Foreign key constraint not replicating

  
We have a merge replication setup with one publisher/distributor and several subscribers.  Several of the tables being replicated have foreign key constraints and these replicate without issue.  However, some foreign key constraints that utilize cascading do not replicate.  To make matters worse, some tables with these cascading fk constraints replicate fine while others do not.  Has anyone run across this behavior and is there a fix for it?  The cascades will dramatically reduce our merge conflicts and help maintain the integrity of the data so we need to keep them in place.
