Sqlexception Number 2601
code: update tender set te_status='D' where rq_no like 'Q052401C' AND te_year like '2012' and te_no like 'n0066' if I place any other character in place of 'D' in te_status, update is successful except for 'D' e.g.: set te_status='S' When I run SELECT * FROM TENDER WHERE rq_no LIKE 'Q052401C' AND te_year LIKE '2012' AND te_no LIKE 'n0066' , it returns a single row.

Sql Error 2601
Cannot insert duplicate key in object 'dbo.tender'. The duplicate value is (N0066, Q052401C, D, 2012) The statement has been terminated. What does all these mean? sql-server sql-update share|improve this question edited Mar 14 '13 at 6:08 Simon MᶜKenzie 4,997132744 asked Mar 14 '13 at 5:35 user2168350 612 add a comment| 1 Answer 1 active oldest votes up vote 2 down vote It means you have a primary key defined on that table, which consists of the fields relating to the values it displayed - i.e. (N0066, Q052401C, D, 2012) - and that if you change the te-status field to D on the row you are updating, then this results in a primary key that already exists. Depending on the DB you use, you sometimes can't UPDATE a primary key field - you should do a DELETE of the old row and an INSERT of the changed row (with the new key). share|improve this answer edited Mar 14 '13 at 7:07 answered Mar 14 '13 at 5:46 Roger Rowland 18k83660 add a comment| Your Answer draft saved draft discarded Sign up or log in Sign up using Google Sign up using Facebook Sign up using Email and Password Post as a guest Name Email Post as a guest Name Email discard By posting your answer, you agree to the privacy policy and terms of service.

Question 0 Sign in to vote Hi What is the difference between Sql Server 2005 violation of unique key constraint sql server errors 2601 and 2627? How could one cause error 2627? Thanks Sunday, August 13, 2006 6:54 PM Reply | Quote Answers 1 Sign in http://stackoverflow.com/questions/15401952/sql-server-update-error-msg-2627 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 https://social.msdn.microsoft.com/Forums/sqlserver/en-US/272c3c7e-0819-4750-a8e8-ae364be34f01/errors-2601-and-2627?forum=transactsql 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 sql error 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 violation of primary 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 (SELECT 'X' FROM [dbo].[Loan Type] WHERE [Loan Type ID] = 'HOME EQUITY') INSERT INTO [dbo].[Loan Type] ( [Loan Type ID], [Name] ) VALUES ('HOME EQUITY', 'Home Equity Loan') Related Articles : Frequently Asked Questions - SQL Server Error Messages Frequently Asked Questions - INSERT Statement Frequently Asked Questions - SELECT Statement
