Vous avez juste besoin d'un WHERE
clause je pense.
INSERT INTO SN_IO ( [C1] ,[C2] ,[C3] )
SELECT [C1] ,[C2] ,[C3]
FROM OPENXML (@currRecord, 'ios/io', 1)
WITH ([C1] [varchar](25) 'C1',
[C2] [varchar](25) 'C2',
[C3] [varchar](20) 'C3' )
WHERE [C1] IS NOT NULL AND [C2] IS NOT NULL AND [C3] IS NOT NULL
Ou vous pouvez le faire dans le XPath à la place, ce qui, je suppose, peut être plus efficace
FROM OPENXML (@currRecord, 'ios/io[C1 and C2 and C3]', 1)
