--如果表是插入，则同步更新AlarmsMiddleTbl

IF EXISTS(SELECT 1 FROM inserted) AND NOT EXISTS(SELECT 1 FROM deleted)

BEGIN

INSERT INTO [PHS].[dbo].[AlarmsMiddleTbl]

SELECT i.[Id], i.[SequenceId], i.[code], i.[alarmdefineid],

CONVERT(varchar,i.[occurTime],120), i.[confirmation], i.[ConfirmationTime],

i.[MaintenanceName], i.[MaintenanceProcedure],

i.[ClearTime], i.[screen],CONVERT(varchar, getdate(), 120)

FROM inserted i

END



--如果表是更新某个字段，则同步更新AlarmsMiddleTbl

IF NOT EXISTS(SELECT 1 FROM inserted) AND EXISTS(SELECT 1 FROM deleted) AND

UPDATE(ConfirmationTime)

BEGIN

INSERT INTO [PHS].[dbo].[AlarmsMiddleTbl]

SELECT d.[Id], d.[SequenceId], d.[code], d.[alarmdefineid],

CONVERT(varchar,d.[occurTime],120), d.[confirmation], d.[ConfirmationTime],
