I have this table:

CREATE TABLE [dbo].[Location](
[LocationID] [int] IDENTITY(1,1) NOT NULL,
[Location] [nvarchar](255) NOT NULL,
[Product_Code] [nvarchar](255) NOT NULL UNIQUE,
[LocationProductStockAmt] decimal(18,2),
CONSTRAINT pk_Location_ID PRIMARY KEY (LocationID),
CONSTRAINT fk_Location_ProductCode FOREIGN KEY (Product_Code) REFERENCES Product(Product_Code),
) ON [PRIMARY]

I created this dummy data:

INSERT INTO LOCATION VALUES ('Johannesburg', '1231', 4000)
INSERT INTO LOCATION VALUES ('Pretoria', '1232', 7236)
INSERT INTO LOCATION VALUES ('East London', '1233', 1256)
INSERT INTO LOCATION VALUES ('Cape Town', '1234', 1258)
INSERT INTO LOCATION VALUES ('Bloemfontein', '1235', 1458)
INSERT INTO LOCATION VALUES ('Rustenburg', '1236', 2145)
INSERT INTO LOCATION VALUES ('Cape Town', '1237', 1236)
INSERT INTO LOCATION VALUES ('Polokwane', '12310',1256)
INSERT INTO LOCATION VALUES ('Kimberly', '1238', 1256)
INSERT INTO LOCATION VALUES ('Welkom', '1239', 1235)

Now I need to create a database object that When a record or records are added or altered by whatever means to Location and the record exists already, based on the "Code" field then the record should be updated with a suffix of " - Updated", if the record does not exist insert the new record

Help please.

What version of SQL server are you using?

If 2008+ then I'd suggest you use a merge statement. Other wise you can "upsert" (combination of update and insert).

here is a link that may help:

EDIT: Too early in the morning, I thought I was still in the "New to SQL Server" forum. So, yeah, I'd suggest a Merge statement. :)
