The INSERT statement conflicted with the FOREIGN KEY constraint
(3 answers)
Closed 6 years ago.
The INSERT statement conflicted with the FOREIGN KEY constraint "FK__faredestin__svno__503BEA1C". The conflict occurred in database
"travelproject", table "dbo.bus", column 'svno'. The statement has
been terminated.
svno column is used as FOREIGN KEY in table.you have to consider FOREIGN KEY hierarchy while insert/delete operation.And FOREIGN KEY must be unique value and record must be in main table for given FOREIGN KEY.
while Inserting in to table check what value goes in svno column and check whether their is record for given svno in table where svno is used as a PRIMERY KEY.

I am trying to migrate a table which has 2 colums.
Id - Primarky key
Parent ID - Foreign key populated by the value above (Id).
(So basically the FK is in the same table)
When I migrate this, I get the following error.
"The UPDATE statement conflicted with the FOREIGN KEY SAME TABLE constraint"
Please let me know how to deal with this.
Thanks in advance
Disable the foreign key constraint first. Then migrate your data. And afterwards you can enable the constraint again.
ALTER TABLE Purchasing.PurchaseOrderHeader
NOCHECK CONSTRAINT FK_PurchaseOrderHeader_Employee_EmployeeID;
ALTER TABLE Purchasing.PurchaseOrderHeader
CHECK CONSTRAINT FK_PurchaseOrderHeader_Employee_EmployeeID;

FOREIGN KEY SAME TABLE error - but foreign key doesn't exist
(1 answer)
Closed 6 years ago.
I like to know if it's possible to create a self refering constraint using an ALTER TABLE statement. (tsql SQL Server 2012)
expected I have a table with just a Primary Key called ID and column called parent_id
I want to do something like this:
ALTER TABLE myTable
ADD CONSTRAINT FK_myTablemyTable
FOREIGN KEY (parent_Id)
REFERENCES myTable(Id)
but I just get the error:
The ALTER TABLE statement conflicted with the FOREIGN KEY SAME TABLE constraint
Is there an alternative way to get the statement working, or do you have to recreate the whole table in this case ?
Hope somebody is able to help
Cheers
Problem solved
I am creating some kind of table migration tool and have not realized that the data was inserted already ...
Problem was that the root element was Inserted with parent_id = 0 and not null...
So there is no mistake in the SQL statement.
now it's working
Issue
I have to table "Account_Manager" and "Partner" and both table contains foreign Key of each other and now I want to add data and it show the error Foreign Key conflict issue.
Guide me how I can insert data into these two table.
Table 1
Table 2
Make both columns (designated as FKs) nullable. Thats only way you can make circular reference/FK
I tried many forums but was not satisfied - I have a table that has a primary key and foreign key relation.
I have to delete table rows with primary key so I need to remove the constraints before deleting.
I used:
delete from [docd_metadata].[docd_metadata].[STATEMENT_IMAGES]
where [statement_image_id]= 05291520275
I got error:
The DELETE statement conflicted with the REFERENCE constraint "fk_stmnt_image_StmntImageId". The conflict occurred in database "docd_metadata", table "docd_metadata.STATEMENT_CAMPAIGN", column 'STATEMENT_IMAGE_ID'.
so I tried :
ALTER TABLE[docd_metadata].[docd_metadata].[STATEMENT_IMAGES]
DROP CONSTRAINT [fk_stmnt_image_StmntImageId]
Now I am getting :
Constraint 'fk_stmnt_image_StmntImageId' does not belong to table 'STATEMENT_IMAGES'
Schema:
Also:
Any suggestion please?
If you really closely read the error message, it's clear that the FK constraint is on table docd_metadata.STATEMENT_CAMPAIGN and not on STATEMENT_IMAGES - so therefore, you must use this SQL to drop the FK constraint:
ALTER TABLE [docd_metadata].[STATEMENT_CAMPAIGN]
DROP CONSTRAINT [fk_stmnt_image_StmntImageId]
The FK goes from table [docd_metadata].[STATEMENT_CAMPAIGN] (column STATEMENT_IMAGE_ID) to [docd_metadata].[STATEMENT_IMAGES] - one table has the primary key, which another table references via its foreign key.

How to alter column in the existing table for the primary key and identity. I tried below query but showing Incorrect syntax near the keyword 'identity'.
alter table IAM_Software_Licence_Master
alter column SoftwareLicId int identity(1,1) primary key
How can I achieve this..
Its difficult to say what the issues are with changing this on your end as I do not know the table structure or whether or not this is used as a foreign Key. But the below link should give you everything you need:
