我需要所有琴弦的长度 5

原版的 [477, 4770,]

预期 ["477 ", "4770 "]

我怎么能用Ruby做到这一点？

我有一个表,我希望在某些条件下获取数据.我正在使用以下查询获取数据.

SELECT track,
       ytd,
       weekno,
       [unit] 
FROM SMIrawdataFinal 
WHERE unit IS NOT NULL AND tracktype='focus' AND track='A' AND ytd IS NOT NULL

原始表(数据)如下所示.

track   ytd    weekno    unit
A      (Blank)   1        1
A      (Blank)   2        2
A      (Blank)   3        3
A        19      5        5
A      (Blank)   4        4

我在sql server中使用PIVOT得到了以下数据.我的问题是如何删除空值并在一行中获取相同的数据.

autoId  track   ytd   col4   col3   col2    col1    
-------------------------------------------------
1         A   (Blank)  NULL    4      3       2  
2         A     19     5     NULL    NULL    NULL

下面是我的SQL查询:

SELECT * 
FROM (
    SELECT track,ytd,weekno,[unit]
    FROM SMIrawdataFinal …

我有两个表Test和TestHistory

CREATE TABLE [dbo].[TEST](
    [ID] [int] NULL,
    [Name] [varchar](10) NULL,
    [Status] [char](1) NULL,
    [CreatedDate] [datetime] NULL
) ON [PRIMARY]

GO

CREATE TABLE [dbo].[Test_History](
    [ID] [int] NULL,
    [Name] [varchar](10) NULL,
    [Status] [char](1) NULL,
    [CreatedDate] [datetime] NULL
) ON [PRIMARY]

GO

INSERT INTO TEST ([ID],[Name],[Status],[CreatedDate])values (1,'Mohan','A',GETDATE())

创建的触发器:

ALTER TRIGGER [dbo].[trg_Test] 
     ON [dbo].[TEST]
     FOR UPDATE 
     AS

     Declare @ID INT;
     Declare @Name varchar(10);
     Declare @Status CHAR(2);
     Declare @CreatedDate DATETIME;


     Select @ID = I.ID from INSERTED I
     Select @Name = I.Name from INSERTED I
     Select …

您可以在SQL Server的结果集中显示特殊的Unicode字符吗？

例如,我如何显示这些字符???？
