Question

当我执行insert a log record to a table时，我想stored procedure 首先，

我创建了一个包含3列名为

的表

ID（自动增量），消息（VARCHAR），CREATED_ON（DATETIME）

其次我写了一个程序：

 create  PROCEDURE        DO_LOG(@MSG_IN VARCHAR) 
 as
 BEGIN

 INSERT INTO test.dbo.TB_ETLLOG(MESSAGE,CREATED_ON) 
 VALUES(@MSG_IN,GETDATE());
 END;

我想在执行另一个程序时写日志，所以我使用这个

EXEC DO_LOG @MSG_IN ='Start DO_ACCOUNT_AML'

但它没有写日志到表。我的代码中有错误吗？感谢

以下是创建日志存储过程的方法，可以将其添加到代码中：

创建表格：

    CREATE TABLE [dbo].[Log](
        [LogID] [int] IDENTITY(1,1) NOT NULL,
        [LogTime] [datetime] NOT NULL,
        [LogAction] [varchar](50) NOT NULL,
        [LogNote] [varchar](max) NOT NULL,
     CONSTRAINT [PK_CourionLog] PRIMARY KEY CLUSTERED 
    (
        [LogID] ASC
    )WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
    ) ON [PRIMARY] TEXTIMAGE_ON [PRIMARY]
    GO

创建存储过程：

CREATE PROCEDURE [dbo].[AddLog] 
        @LogAction varchar(50), 
        @LogNote varchar(max), 
        @LogTime datetime = null

    AS
    BEGIN
        -- SET NOCOUNT ON added to prevent extra result sets from
        -- interfering with SELECT statements.
        SET NOCOUNT ON;

            if @LogTime is null
                set @LogTime = getdate();

            INSERT INTO Log(LogTime, LogAction, LogNote)
                Select @Logtime, @LogAction, @LogNote 

    END

用法：

DECLARE @msg VARCHAR(1000);
DECLARE @tmpCount INT;
SET @tmpCount = 1
SET @msg = 'Completed LastName Check: ' + cast(@tmpCount as varchar(10))
EXECUTE [dbo].[AddLog] 'INFO', @msg

EXECUTE [dbo].[AddLog] 'ERROR', 'This is an error message.'

查看日志消息：

select * from [dbo].[Log]

执行存储过程时将日志写入表SQLserver
