在Sql Server触发器中判断操作是Insert还是Update还是Delete
DECLARE @IsInsert bit, @IsUpdate bit, @IsDelete bitIF EXISTS(SELECT 1 FROM inserted) AND NOT EXISTS(SELECT 1 FROM deleted) SET @IsInsert = 1ELSE SET @IsInsert = 0IF EXISTS(SELECT 1 FROM inserted) AND EXISTS(SELECT 1 FROM deleted) SET @IsUpdate = 1ELSE SET @IsUpdate = 0IF NOT EXISTS(SELECT 1 FROM inserted) AND EXISTS(SELECT 1 FROM deleted) SET @IsDelete = 1ELSE SET @IsDelete = 0 create trigger Update_Del on Table for update,delete as if not exists(select 1 from inserted) begin /*inserted表无记录，是删除*/ end else begin /*是更新*/ end go
