Primary key constraint violation problem using Insert in SQL Server Management Studio 2008

I am getting the following error when trying to insert new records into a table.
Msg 2627, Level 14, State 1, Line 7
Violation of PRIMARY KEY constraint 'MLFML_PK'. Cannot insert duplicate key in object 'dbo.MLFML'.
The statement has been terminated.

Here is my code:

declare @TODAY varchar(10)
SET @TODAY = (SELECT CONVERT(VARCHAR(10), GETDATE(), 101) AS [MM/DD/YYYY])
 
 
INSERT INTO MLFML (BOOK_QTY, CREATED_BY, DATE_CREATED, DATE_LAST_ACT, DATE_LAST_ISSUE, DATE_LAST_PHY, DATE_LAST_PRINT,
DATE_LAST_RECPT, MLFML_USER_1,  MLFML_USER_2, MLFML_USER_3, MLFML_USER_4, ON_HAND_QTY, OPERATOR_ID, PART_ID, PHYSICAL_QTY, 
STOCK_LOCATION, STORES_CODE, DATE_LAST_UPDT,  TIME_LAST_UPDT,  DELETE_FLAG) 

SELECT 0, 'SYS.DM', GETDATE(), @TODAY, NULL, @TODAY, NULL, @TODAY, 0, 0, '', '', PI.QUANTITY, 'SYS.DM', PI.PART_ID, 0, PI.TO_LOCATION, 
PI.STORES_CODE,  convert(char(11),getdate(),101), convert(char(5),getdate(),108), 'N'

FROM PISTOCKTRANSFER PI, MLFML ML
WHERE ((PI.STORES_CODE <> ML.STORES_CODE) AND (PI.PART_ID <> ML.PART_ID) AND (PI.TO_LOCATION <> ML.STOCK_LOCATION))

Open in new window


The primary key is STORES_CODE, PART_ID, STOCK_LOCATION

I try and validate the records by using the following select:

 
SELECT * FROM MLFML ML
JOIN PISTOCKTRANSFER PI
ON PI.PART_ID = ML.PART_ID
WHERE (ML.STORES_CODE = PI.STORES_CODE) AND (ML.STOCK_LOCATION = PI.TO_LOCATION)

Open in new window


Of course I get 0 results from the above SELECT statement, however I get the primary key constraint when trying to insert.  
Please help

you need to used left join or if not exists

 
-- whit a left join
SELECT 
	* 
FROM 
	PISTOCKTRANSFER PI
	left join MLFML ML	
		ON PI.PART_ID = ML.PART_ID
			and PI.STORES_CODE = ML.STORES_CODE
			and PI.STOCK_LOCATION = ML.STOCK_LOCATION
WHERE 
	ml.PART_ID is null


-- whit if not exists
SELECT 
	* 
FROM 
	PISTOCKTRANSFER PI
WHERE 
	not exists 
	(
			select 
				*
			from 
				MLFML ML	
			where 
				PI.PART_ID = ML.PART_ID
				and PI.STORES_CODE = ML.STORES_CODE
				and PI.STOCK_LOCATION = ML.STOCK_LOCATION
	)

The problem is with the Insert, not the Select.

However, for information only, I did use the exact where clause with the "not exists" in my insert statement and still got the same error message.

I know the select I sent was to put in the insert statement.

2 possibility,
1- your primary key is not STORES_CODE, PART_ID, STOCK_LOCATION
2- you have a trigger on the table MLFML  trying to insert something that create duplicate

 
declare @TODAY varchar(10)
SET @TODAY = (SELECT CONVERT(VARCHAR(10), GETDATE(), 101) AS [MM/DD/YYYY])
 
 
INSERT INTO MLFML (BOOK_QTY, CREATED_BY, DATE_CREATED, DATE_LAST_ACT, DATE_LAST_ISSUE, DATE_LAST_PHY, DATE_LAST_PRINT,
DATE_LAST_RECPT, MLFML_USER_1,  MLFML_USER_2, MLFML_USER_3, MLFML_USER_4, ON_HAND_QTY, OPERATOR_ID, PART_ID, PHYSICAL_QTY, 
STOCK_LOCATION, STORES_CODE, DATE_LAST_UPDT,  TIME_LAST_UPDT,  DELETE_FLAG) 
-- whit if not exists
SELECT 
	* 
FROM 
	PISTOCKTRANSFER PI
WHERE 
	not exists 
	(
			select 
				*
			from 
				MLFML ML	
			where 
				PI.PART_ID = ML.PART_ID
				and PI.STORES_CODE = ML.STORES_CODE
				and PI.STOCK_LOCATION = ML.STOCK_LOCATION
