Question

我有一张包含以下数据的表格。

我正在尝试根据以下规则更新丢失的Relation Number记录：

当两行POSTCODE相同时
如果Phone1或phone2或phone3匹配，或Account name匹配（帐户名％）

表：

DECLARE @MASTER TABLE
(
[Account Number] VARCHAR(8),    
[Account Name] VARCHAR (100),   
RelationNo VARCHAR(8),  
BRNAME VARCHAR(40), 
POSTCODE  VARCHAR(10),
PHONE001 VARCHAR(250),
PHONE002 VARCHAR(250),
PHONE003  VARCHAR(250)
)

INSERT @MASTER


SELECT '40045002', 'REVIVE', '', '2', 'WA168QE', '', '', '' UNION ALL -- Account Name Match
SELECT '60045002', 'REVIVE! MANCHESTER', '120002', '2', 'WA168QE', '07967967404', '', ''  UNION ALL -- Account Name Match


SELECT 'C2128617', 'KGN ELECTRIC', '', '85', 'RH54JH', '', '07773886450', '02072542392' UNION ALL -- Phone  match
SELECT 'D2128617',  'J & M SERVICES', '121542', '9', 'RH54JH', '', '', '07773886450' UNION ALL -- Phone  match


SELECT 'E3085970', 'RICHARDS AUTO SERVICES', '122390', '212','SY120EW', '01691622421',  NULL, NULL UNION ALL -- Not To be in Output Nothing Match
SELECT 'T5000647', 'Thomas Halsall-mooney', '', '212', 'SY120EW', '07493580779',  NULL,  NULL  -- Not To be in Output Nothing Match



 Output
'40045002',  'REVIVE', '120002', '2', 'WA168QE', '', '', ''  -- Account Name Match
'60045002', 'REVIVE! MANCHESTER', '120002', '2', 'WA168QE', '07967967404', '', ''   -- Account Name Match
'C2128617', 'KGN ELECTRIC', '121542', '85', 'RH54JH', '', '07773886450', '02072542392'  -- Phone  match
'D2128617', 'J & M SERVICES', '121542', '9', 'RH54JH', '', ''  ,'07773886450'  -- Phone  match

然而，代码并没有给出完美的结果。

;with cte as (
select o.*, x.FoundRelationNo
from @MASTER as o
cross apply (
  select top 1 FoundRelationNo = i.RelationNo 
    from @MASTER  as i
    where i.POSTCODE = o.POSTCODE
      and nullif(i.RelationNo,'') is not null
      and (
        nullif(i.PHONE001,'0') in (nullif(o.PHONE001,'0'), nullif(o.PHONE002,'0'),nullif(o.PHONE003,'0'))
      or nullif(i.PHONE002,'0') in (nullif(o.PHONE001,'0'), nullif(o.PHONE002,'0'),nullif(o.PHONE003,'0'))
      or i.[Account Name] like o.[Account Name]+'%')

    ) as x
where nullif(o.RelationNo,'') is null
 and (o.PHONE001 > '0' or o.PHONE001 > '0' or o.PHONE001>'0')
 )

 update cte set RelationNo = FoundRelationNo

请帮帮我。

;with cte as (
select o.*, x.*
from @MASTER as o
cross apply (
  select top 1 
      MatchedRelationNo = i.RelationNo 
    , MatchedAccountNumber = i.[Account Number]
    , MatchedOn = case 
        when i.[Account Name] like o.[Account Name]+'%'
          then 'Account Name' 
        when nullif(i.PHONE001,'') in (o.PHONE001, o.PHONE002,o.PHONE003)
          then 'Phone001'
        when nullif(i.PHONE002,'') in (o.PHONE001, o.PHONE002,o.PHONE003)
          then 'Phone002'
        when nullif(i.PHONE003,'') in (o.PHONE001, o.PHONE002,o.PHONE003)
          then 'Phone003'

          then i.PHONE001
        when nullif(i.PHONE002,'') in (o.PHONE001, o.PHONE002,o.PHONE003)
          then i.PHONE002
        when nullif(i.PHONE003,'') in (o.PHONE001, o.PHONE002,o.PHONE003)
          then i.PHONE003
        else null
        end
    from @MASTER  as i
    where i.POSTCODE = o.POSTCODE
      and nullif(i.RelationNo,'') is not null
      and (
         nullif(i.PHONE001,'') in (o.PHONE001, o.PHONE002,o.PHONE003)

       )
   ) as x
where nullif(o.RelationNo,'') is null
 )
select * from cte
--update cte set RelationNo = MatchedRelationNo
--select * from @Master

结果：

如果存在则检查多列中的值，然后在SQL 2008中更新Row-
