So current identity of the table is lower that already existing values, and adding new rows causes this error. Check cur

How could one cause error 2627? Thanks Sunday, August 13, 2006 6:54 PM Reply | Quote Answers 1 Sign in error 262 to vote 2601 - Violation in unique index 2627 - Violation in unique constraint (although it is implemented using unique index) The error messages are used to distinguish the object on which the violation happens (unique constraint or unique index). Also, constraints are logical entities and part of sql error 262 the ANSI SQL standard whereas indexes are physical structures that are not part of the standard. So the ANSI SQL standard doesn't talk about how a primary key or unique constraint should be enforced by a database engine. It just happens that SQL Server enforces primary key/unique constraints using an unique index underneath the covers. And when you create logical data model you can use only constraints. Indexes are created on the tables for optimizing certain access paths or queries and not part of the logical data model.

Cannot insert duplicate key in object Table Name. SQL Server Error Messages - Msg 2627 - Violation of PRIMARY KEY constraint Constraint Name. Cannot insert duplicate key in object Table Name. SQL Server Error Messages - Msg 2627 Error Message Server: Msg 2627, Level 14, State 1, Line 1 Violation of PRIMARY KEY constraint Constraint Name. Cannot insert duplicate key in object Table Name. Causes: This error occurs when you are trying to insert a new record into a table that contains a PRIMARY KEY constraint and the key of the record being inserted already exists in the table. As an example, suppose you have a table containing the different loan types that your application are accepting: CREATE TABLE [dbo].[Loan Type] ( [Loan Type ID] VARCHAR(20) NOT NULL PRIMARY KEY, [Name] VARCHAR(50) NOT NULL ) GO And your table already contains the following loan types: Loan Type ID Name ------------- ------------------ CAR Car Loan HOME Home Loan HOME EQUITY Home Equity Loan PERSONAL Personal Loan STUDENT Student Loan If you try to add another loan type where the Loan Type ID already exists without knowing that it is already in the table, you will get the error. INSERT INTO [dbo].[Loan Type] ( [Loan Type ID], [Name] ) VALUES ('HOME EQUITY', 'Home Equity Loan') Server: Msg 2627, Level 14, State 1, Line 1 Violation of PRIMARY KEY constraint 'PK_Loan_Type'. Cannot insert duplicate key in object 'Loan Type'. The statement has been terminated. Solution / Work Around: To avoid this error, check first if a record with a given key already exists in the table and if it doesn’t exist yet, then perform the INSERT: IF NOT EXISTS (SELE
