I have two tables Person & Location where Location has a primary key LocationId and Person has a foreign key LocationId.
Sometime ago I used the Database Diagrams visual tool of SQL Server Management Studio Express to create the foreign key relationship between the two tables - i.e. "visually" (drawing a line between the PK & FK LocationId elements of both tables).
Time has passed and I recently noticed that, upon retrieving my saved diagram, the foreign key relationship had "fallen off" (i.e. the many-to-one line was no longer showing in the diagram).
After recreating the relationship (redrawing the line) I find that I get an error message when I try to save the diagram:
Post-Save Notifications
[!] Errors were encountered during the save process. Some database objects were not saved.
'Location' table saved successfully
'Person' table
- Unable to create relationship 'FK_Person_Location'.
The ALTER TABLE statement conflicted with the FOREIGN KEY constraint "FK_Person_Location". The conflict occurred in database "mydb", table "dbo.Location", column 'LocationId'.
When I go back to the object explorer and view the dependencies for the two tables, there is no dependency (between these two tables) revealed. When I try to create the foreign key constraint manually (T-SQL) it again says can't add the constraint. It comes up with an error as follows:
ALTER TABLE Person
ADD FOREIGN KEY (LocationId) REFERENCES Location (LocationId)
Msg 547, Level 16, State 0, Line 2
The ALTER TABLE statement conflicted with the FOREIGN KEY constraint "FK__Person__LocationId__793DFFAF". The conflict occurred in database "mydb", table "dbo.Location", column 'LocationId'.
(Note: Each time I do this, the 8 hexadecimal character suffix changes.)
When I try to drop the foreign key:
alter table Person
drop constraint FK__Person__LocationId
it comes back with the error:
Msg 3728, Level 16, State 1, Line 2
'FK__Person__LocationId' is not a constraint.
Msg 3727, Level 16, State 0, Line 2
Could not drop constraint. See previous errors.
So it seems that there's some kind of goof up here. Can anybody shed light on this / tell me how to fix it?
I need to drop and recreate few subscriptions in transactional publication Do I need to worry about log marker issues ? Do I need to set the primary and replicate databases in 'DBO use only'
The Primary and Replicate databases are being accessed all the time.
I have come across a user that has error 2525 errors on sysobjects tables throughout their SQL 6.5 system. The ids match and I can identify the index. But as they are system tables I cannot drop or rebuild the indexes.
Any ideas please?
The errors have been occuring for some time, so it is not an option to restore. I would like to avoid having to transfer data to and from another SQL Server.
I'm having a heck of a time trying to upload data to an excel spreadsheet. This works perfectly in sql 2000 but I've been having problems with 2005

Hello, I need to retrieve all the information about all the foreign key constraints,inorder to store them temporarily (to be deleted later)and then recreated after making the necessary modifications to the concerned tables. The stored proc sp_helpconstraint shows all the constraint types, their user-defined or system-supplied name, the columns on which they have been defined, and the expression that defines them.But I don't know whether it can be manipulated to get what I want.I need to get it done programmatically..so that I can integrate it in my program which I'm building up progressively. Any help or scripts would be appreciated!
I have found an (encrypted) SP which takes ~20 seconds to run on one of our client DBs.
If I drop and recreate (or alter) the SP giving it the same contents it will run in ~1 second.
I need to know 1. why the sp started running so slowly 2. how to stop it happening again 3. how to fix it without resorting to drop/recreate (I can't exactly write a batch script to recreate all our sps every so often)
I have tried sp_updatestats and sp_recompile before running the sp to no avail...
Here is my issue I am new to 2005 sql server, and am trying to take my old data which is exported to a txt file and import it to tables in sql. The older database is non relational, and I had made several exports for the way I want to build my tables. I built my packages fine and everything is working until I start building relationships. I remove my foreign key and the table with the primary key will get updated for the package again. I need to update the data daily into sql, and once in it will only be update from the package until the database is moved over.
It will run and update with a primary key until I add a foreign key to another database.
Here is my error when running the package when table 2 has a foreign key.
[Execute SQL Task] Error: Executing the query "TRUNCATE TABLE [consumer].[dbo].[Client] " failed with the following error: "Cannot truncate table 'consumer.dbo.Client' because it is being referenced by a FOREIGN KEY constraint.".

student --- enrollment is 1- to - many . ssn is pk in student. ssn and courseid is pk in enrollment. later I added the foreign key constraint FK_SSN in enrollment table reference student table. it is ok. enrollment --- lessonhistory is 1-to -many, ssn, courseid and lessonid is pk in lessonhistory . I tried to set FK_SSN foreign key constraint in lessonhistory table reference enrollment table, it always show error message " no primary key in referewnce talbe enrollment " I don't know how to fix it. could you help me out, thanks!!
I have a created a database with nearly 20 tables in it, so I cannot post all of my statements. I am having an issue though with two tables' referential integrity when it comes to foreign key constraints. I want to constrain them to cascade updates from the primary key tables, but I keep getting the error msg 1785

I have tried making an update trigger but it does not work.
Hello, I have hit the wall here...can't make sense of this one.
I have a script that creates a PRIMARY KEY constraint called PK_tblDRG CODE:
ALTER TABLE [dbo].[tblDRG] ALTER COLUMN [record_id] Uniqueidentifier NOT NULL Go ALTER TABLE [dbo].[tblDRG] WITH NOCHECK ADD PK_tblDRG PRIMARY KEY CLUSTERED ( [record_id] ) WITH FILLFACTOR = 90 ON [PRIMARY]
if exists (select * from dbo.sysobjects where id = object_id(N'[dbo].[PK__tblDRG]') and OBJECTPROPERTY(id, N'IsPrimaryKey') = 1) ALTER TABLE [dbo].[tblDRG] DROP CONSTRAINT PK__tblDRG
I am attempting to write a DTS package that copies the data across from one instance of a db on a test server to a second instance on to the live server. It has to replace all the exisiting date so I can't append. Unfortunately, the package keeps giving me errors all of the type "unable to truncate tbl due to foreign key constraints". Is there a way round this?

Hi, I am fairly new to SQL server Express and I have quite a simple database set up and I am trying to test it out with data. I have €śPain Reading€? and €śWorsen Factors€? tables with a 1: M relationship. The primary key in the Pain reading table is ReadingID which is being set using getdate() for the default value. I am getting the following error when attempting to add a new row to the €śWorsen Factors€? table:
No row was updated
The data in row 1 was not committed. Error source:.Net SqlClient Data Provider Error Message: The insert statement conflicted with the FOREIGN KEY constraint "FK_WorsenFactor_PainReading1". The confilct occurred in database "paindata", table "dbo.PainReading", column 'ReadingID'. The statement has been terminated.
When I try to like Rkey from both tables as a foreign key relationship, I get an error that the columns in one table "do not match an existing primary key or UNIQUE constraint. (I've tried it both ways and get the same error.)
Hi, i have two tables, one is department-Table(Master table) and other is employee-table(Child table). DNO is a data field which is common in both the table. "DNO" is primary key in department-table and "DNO" is foreign key in child table.
I am trying to insert rows in the table i found the following error:
The INSERT statement conflicted with the FOREIGN KEY constraint "FK_Employee_Department". The conflict occurred in database "Project", table "dbo.Department", column 'Dno'.
Yesterday I made alot of updates to to various tables within a databse, to update some records I had to drop the foreign key constraint, but when I try to add the constraint back I get an error message (in red) ALTER TABLE [dbo].[ITEMS] ADD CONSTRAINT [FK_ITEMS__ITEM_CATEGORIES] FOREIGN KEY ( [ITC_ID] ) REFERENCES [dbo].[ITEM_CATEGORIES] ( [ITC_ID] ) ON UPDATE CASCADE NOT FOR REPLICATION , CONSTRAINT [FK_ITEMS__ITEM_TYPES] FOREIGN KEY ( [ITY_ID] ) REFERENCES [dbo].[ITEM_TYPES] ( [ITY_ID] ) ON UPDATE CASCADE NOT FOR REPLICATION GO Server: Msg 1785, Level 16, State 1, Line 1 Introducing FOREIGN KEY constraint 'FK_ITEMS__ITEM_CATEGORIES' on table 'ITEMS' may cause cycles or multiple cascade paths. Specify ON DELETE NO ACTION or ON UPDATE NO ACTION, or modify other FOREIGN KEY constraints. Server: Msg 1750, Level 16, State 1, Line 1 Could not create constraint. See previous errors
any suggestions? I tried modifying the statement to ON UPDATE NO ACTION, but I get exactly the same error message. Any help would be much appreciated...thanks in advance
A website that I'm working on has users sign in and keeps a log of the pages they go to. The log table has a foreign key in it that links to the username is the users table. I need to update the username for one of the users but the foreign key is preventing me from doing so. What is the benefit of having a foreign key like this? Can I delete it to update the username or is there a better way?
I need to make some changes to tables in a database. To do this requires that I "alter table" and "drop constraint" All constraints drop properly, except one. The last one will churn away forever in query analyzer and never drop. I am unable to make the necessary changes until this completes. I am guessing that there is a data issue that is keeping the constraint from being dropped. Any ideas on how to proceed? Thanks!
I have a table called suppliers where i type my suppliers details. I have also a table called supp_corellation in which i have the proffesion of my suppliers.
there is one column in the table of suppliers which it takes data from the table supp_corellation . Is it possible to choose the values from a list instead of typing in my table (lets say drop down list)???
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!
I have two tables: table 1 and table 2. The primary key of table is composite key of two collumns and table 2 is the child of parent table 1. Is it possible to create / define a foreign key constraint using a composite primary key?
I am importing data from a flat, comma delimited text file. It appears to properly import all the records and then on the last record it give me the error
INSERT statement conflicted with COLUMN FOREIGN KEY constraint for 'EOR_ITE_REF_EOR'.
Then it goes on to tell me the database, table and column in which the problem occured which is the first column in the table. It looks like it doesn't like the end of the file for some reason (EOR, end of record?) so I tried deleting the last record from the file and it still does it. I do have a file that I have imported that worked so I tried copying the last record of that file and pasting it into the last record of the file I wanted but that did not work either. The ends of file that works and the file that doesn't work look the same and I can find nothing on 'EOR_ITE_REF_EOR'. Any help would be appreciated.
why it is not possible to create a Foreign key to a Unique constraint?
Table A has column 1 holding a Primay key and two columns (2 and 3) holding a Unique combination (and some more columns).He created an Unique constraint on column 2 and 3 together.
He wanted to use this Unique combination to point to table B (instead of the table 1's PK) so he tried to create a foreign key on a column in table B but an error popped up prompting;
The columns in table 'TABLE_A' do not match an existing primary key or UNIQUE constraint.
Ok - these two columns ar no PK but the hold an Unique constraint......
