I have a database which stores the Accounts and productsinformation. Account is always updated with products values. Forexisting products, I have to use UPDATE SQL command. If newproducts are added into Products table, the new Product rowsneed to be inserted into Accounts table.

Is there a way I can INSERT a record, if Update returnsNo-Record-found with minimum trips to database? I'm using Accessdatabase and CSharp.
 
Hi,

What you could do is to call stores procedure and inside of this stored
procedure first check if record exists using EXISTS function (I do not
remember exact syntax, but it should look like)

If EXISTS (SELECT .... WHERE .....)
UPDATE ...
ELSE
INSERT ....
