Error while deleting records from table

[Nitin Daphale]

Table Name => PropDocument
Column1 => propertyid ( foreign key from Property table )
Column2 => documentid ( foreign key from Document table )

The error ( in the attached image ) comes when
I try to delete the record.
This error comes often when there are 2 records with same values as you can see in the image.

By mistake I have added that records but
now how can I delete the records ?

[finito]

ALTER TABLE Table1

ADD TempID int IDENTITY(1, 1)

Run this in SQLBrowser

It will create another Column and make everything unique

Delete what you want and then delete the column
