SQL - Inserting a row and returning primary key

Question

I have a little witty problem. Say, I inserted a row with some data in a table where a primary key is present. How would one \"SELECT\" the primary key of the row one just i

If you need to retrieve the new index in MS SQL when there are triggers on the table then you have to use a little workaround. A simple OUTPUT will not work. You have to do something like this (in VB.NET):

DECLARE @newKeyTbl TABLE (newKey INT);
INSERT INTO myDbName(myFieldName) OUTPUT INSERTED.myKeyName INTO @newKeyTbl VALUES('myValue'); " & _
SELECT newKey FROM @newKeyTbl;"

If using .NET, then the return value from this query can be directly cast to an integer (you have to call "ExecuteScalar" on the .NET SqlCommand to get the return).
