	[Sex] [NVARCHAR](10) NULL)

CREATE TABLE [dbo].[Test_TriLog](
    [LogId] [INT] IDENTITY(1,1) NOT NULL PRIMARY KEY,
	[TriOn] DATETIME NULL,
	[TriOp] NVARCHAR(50) NULL,
	[Id] [INT] NOT NULL,
	[Name] [NVARCHAR](10) NULL,

CREATE TRIGGER [dbo].[tr_Test_All]

	-- interfering with SELECT statements.
	SET NOCOUNT ON;
	declare @TriOP nvarchar(50)
	--新增
	if exists(select 1 from inserted) and not exists(select 1 from deleted)
	BEGIN
