我想要做的是将与 VhStock.No 关联的所有工作代码合并到一行中。任一列 WkRoDesc.Job_Code END AS WorkNeeded 具有所有工作代码，但下面列出的四个用“,”分隔，然后在另一列中以相同的方式组合这四个工作代码。

SELECT 
--other things selected here
vhstock.No AS [Tag #], 
WkInvReg.Ro_Number

CASE WHEN WkRoDesc.Job_Code = 'Outside AOR' 
         OR WkRoDesc.Job_Code = 'AOR Del'
         OR WkRoDesc.Job_Code = 'AOR L & G'
         OR WkRoDesc.Job_Code = '/Cust PU/D'
    THEN NULL ELSE WkRoDesc.Job_Code END AS WorkNeeded,
  CASE WHEN WkRoDesc.Job_Code = 'Outside AOR' 
         OR WkRoDesc.Job_Code = 'AOR Del'
         OR WkRoDesc.Job_Code = 'AOR L & G'
         OR WkRoDesc.Job_Code = '/Cust PU/D'
    THEN WkRoDesc.Job_Code ELSE NULL END AS DPO



FROM vhstock, WkInvReg, WkRoDesc

WHERE vhstock.no = WkInvReg.Stock_No AND WkInvReg.Ro_Number = WkRoDesc.Ro_Number

我正在使用带有 ODBC 连接的 SQL Server 08 R2 从 SQL Anywhere v.11 数据库进行查询。我使用 Foresight Intelligence 作为界面来进行查询。我无法直接访问这两个数据库，因为它们是由软件供应商管理的。

我怎样才能做到这一点？已经尝试过了，但收到一个没有解释的错误

stuff((
    select ',' + WkRoDesc.Job_Code + ', '
    from WkRoDesc
    where WkRoDesc.Ro_Number = WkInvReg.Ro_Number
      and NOT (WkRoDesc.Job_Code = 'Outside AOR' OR WkRoDesc.Job_Code = 'AOR Del' OR WkRoDesc.Job_Code = 'AOR L & G' OR WkRoDesc.Job_Code = '/Cust PU/D')
   FOR xml path('')
    ), 1, 1, '') AS WorkNeeded,    

stuff((
    select ',' + WkRoDesc.Job_Code + ', '
    from WkRoDesc
    where WkRoDesc.Ro_Number = WkInvReg.Ro_Number
      and (WkRoDesc.Job_Code = 'Outside AOR' OR WkRoDesc.Job_Code = 'AOR Del' OR WkRoDesc.Job_Code = 'AOR L & G' OR WkRoDesc.Job_Code = '/Cust PU/D')
   FOR xml path('')
    ), 1, 1, '') AS DPO

嗨，你试过 groupby 吗？希望这可以帮助

MAX(DISTINCT CASE WHEN WkRoDesc.Job_Code = 'Outside AOR' THEN WkRoDesc.Job_Code END) + ',' + MAX(DISTINCT CASE WHEN WkRoDesc.Job_Code ='AOR Del' THEN WkRoDesc.Job_Code END) 
                  + ',' + MAX(DISTINCT CASE WHEN WkRoDesc.Job_Code ='AOR L & G' THEN WkRoDesc.Job_Code END) + ',' + MAX(DISTINCT CASE WHEN WkRoDesc.Job_Code ='/Cust PU/D' THEN WkRoDesc.Job_Code END) 
                  AS WorkNeeded

结果是 WorkNeeded = 外部 AOR,AOR Del,AOR L & G,/Cust PU/D
