我正在为特定实例中的每个数据库的表安排查询。每个数据库的查询和表都是类似的。我将查询结果指向文本文件。在查询结果之前,我包含了进行特定查询的数据库。但是,在我在AdventureWorks中的测试中,我得到的结果是一个带有很长下划线的数据库名称。

以下是我得到的输出:

DatabaseName
-------------------------------------------------------------------------------
AdventureWorks                                                                                                                          

AttemptDate             
-----------------------

以下是我调用的查询:

set nocount on
use AdventureWorks
GO
select DB_NAME()as DatabaseName
select AttemptDate from dbo.ChangeAttempt

我的问题是:如何缩短数据库名称下面的行?

使用LEFT()

试试这个:

declare @mytabel table (longvalue  varchar(1000))

select longvalue from @mytabel

select left(longvalue,50) as longvalue from @mytabel

输出:

longvalue
----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

(0 row(s) affected)

longvalue
--------------------------------------------------

(0 row(s) affected)

答案 1 :(得分:1)

尝试:

SELECT LEFT(DB_NAME(), 20) AS DatabaseName

答案 2 :(得分:-1)

您从此查询中获得什么输出?

set nocount on
use AdventureWorks
GO
select DB_NAME() as DatabaseName, AttemptDate from dbo.ChangeAttempt
