Question

我希望基于列加入输出，但问题是，其中一列被解析然后通过语句创建

PARSENAME(
   REPLACE(
      replace(
        replace(
          replace(
             replace(dbo.IDENTITY_MAP.Name,'My Company\',''),
          '-VLAN2','')
        ,'.VLAN2\','')
      ,'.Instr\','') 
  , '\' , '.')
,1)

输出

abc
123
abra
cadabra

另一个表的列直接打印为

abc
123
abra
cadabra

我试图解决这个问题：

abc      wine
123      sherry
abra     cognac
cadabra  whisky

和这个

abc       Alaska       Bobby
123       Canada       Jessie
abra      New Zealand  Audrey
cadabra   Maldives     Sammy

进入：

abc      wine    Alaska       Bobby
123      sherry  Canada       Jessie
abra     cognac  New Zealand  Audrey
cadabra  whisky  Maldives     Sammy

请记住，第一列其中一个表是使用PARSENAME

人工创建的

查询第一个输出

SELECT PARSENAME(REPLACE(replace(replace(replace(replace(dbo.IDENTITY_MAP.Name,'My Company\',''),'-VLAN2',''),'.VLAN2\',''),'.Instr\','') , '\' , '.'),1) as "Site",
                   Count (CASE
                            WHEN dbo.SEM_AGENT.AGENT_VERSION LIKE '11.%' THEN 1
                          END) AS 'SEP-11',
                   Count(CASE
                            WHEN dbo.SEM_AGENT.AGENT_VERSION LIKE '12.%' THEN 1
                          END) AS 'SEP-12'...
            FROM   dbo.sem_computer
                   INNER JOIN [dbo].[V_SEM_COMPUTER]
                           ON [dbo].[V_SEM_COMPUTER].COMPUTER_ID = SEM_COMPUTER.COMPUTER_ID ...
            WHERE dbo.IDENTITY_MAP.Name NOT LIKE '%Servers%'
      Group by PARSENAME(REPLACE(replace(replace(replace(replace(dbo.IDENTITY_MAP.Name,'My Company\',''),'-VLAN2',''),'.VLAN2\',''),'.Instr\','') , '\' , '.'),1)
      Order by "Site" DESC

查询第二个输出

SELECT * from dbo.SEPM_Site

我创建了dbo.SEPM_Site，要加入的列实际上是主键！

如果我们在2005年之后谈论一个版本的sql server，为了对你所拥有的内容有所了解，你可以将查询放入CTE并将其与表格连接起来：

;with cte as (
  --- put the parsename query here (without the order by)
)
select 
  *  -- feel free to query what you need from here
from cte
join SEPM_Site ss
  on cte.Site = ss.Site

SQL Query根据已解析的列连接两个表
