Ca se fait juste après l'insert en récupérant la variable systeme qui renvoie le dernier ID entré dans la table, voila la copie de la MSDN la dessus :
@@IDENTITY
Returns the last-inserted identity value.
Syntax
@@IDENTITY
Return Types
numeric
Remarks
After an INSERT, SELECT INTO, or bulk copy statement completes, @@IDENTITY contains the last identity value generated by the statement. If the statement did not affect any tables with identity columns, @@IDENTITY returns NULL. If multiple rows are inserted, generating multiple identity values, @@IDENTITY returns the last identity value generated. If the statement fires one or more triggers that perform inserts that generate identity values, calling @@IDENTITY immediately after the statement returns the last identity value generated by the triggers. The @@IDENTITY value does not revert to a previous setting if the INSERT or SELECT INTO statement or bulk copy fails, or if the transaction is rolled back.
@@IDENTITY, SCOPE_IDENTITY, and IDENT_CURRENT are similar functions in that they return the last value inserted into the IDENTITY column of a table.
@@IDENTITY and SCOPE_IDENTITY will return the last identity value generated in any table in the current session. However, SCOPE_IDENTITY returns the value only within the current scope; @@IDENTITY is not limited to a specific scope.
IDENT_CURRENT is not limited by scope and session; it is limited to a specified table. IDENT_CURRENT returns the identity value generated for a specific table in any session and any scope. For more information, see IDENT_CURRENT.
Examples
This example inserts a row into a table with an identity column and uses @@IDENTITY to display the identity value used in the new row.
INSERT INTO jobs (job_desc,min_lvl,max_lvl)
VALUES ('Accountant',12,125)
SELECT @@IDENTITY AS 'Identity'
