拆分列多个值

Question

我面对的困难，更是15万所记录的客户表中有包含超过一个值（电话）的电话号码列用空格，逗号，短划线，点等中分离出的原始列值是VARCHAR类型最大30.我需要一种方法来检查这些值，并将它们分割成一个新的表中的列相等，然后通过从除去任何特殊字符正常化他们在他们里面。新的列值都不应超过10位。

查找低于目前的表，清楚地描绘了当前的混乱的选择查询结果。柱NO_（ΠΕxxxxxx）是Customer Unique Identifier。柱Phone No_是凌乱一个

通过分离每个数字/， - 或空间必须被分离成新的列

任何文本必须被去除。

少于10位数任何数量的序列，如果序列具有6位数必须加入前缀，如果序列具有9数字和第一个数字序列的始于，数6必须添加为前缀。 对于实施例

the number 342456 must become 2310342456 and the number 944111072 must become 694411072 

的10个数字的数字序列之间的任何点（。）必须被移除以有一个唯一的数字 对于实施例

the number 231.282414 must be 231282414 or 6942.693372 must be 6942693372 

任何帮助非常感谢

例如

if object_id('splitNums') is not null 
    drop function splitNums 
go 

create function splitNums(@nums varchar(30)) 
returns @tr table (n1 varchar(10), n2 varchar(10), n3 varchar(10), n4 varchar(10), n5 varchar(10)) as 
begin 
    declare @v varchar(10) 
    declare @i int 
    insert into @tr values (null, null, null, null, null) 
    declare @ci int = 1 
    while (@ci <= 5) begin 
     if (LEN(@nums) > 0) begin 
      set @i = charindex('/', @nums) 
      if (@i <= 0) 
       set @i = charindex(' ', @nums) 
      if (@i <= 0) 
       set @i = charindex('-', @nums) 
      if (@i <= 0) begin 
       set @v = @nums 
       set @nums = '' 
      end else begin 
       set @v = SUBSTRING(@nums, 1, @i - 1) 
       set @nums = SUBSTRING(@nums, @i + 1, len(@nums) - @i) 
      end 
     end else set @v = '' 
     if (@v = '') break 
     set @v = replace(@v, '.', '') -- more code needed here to remove text 
     if (len(@v) = 6) set @v = '2310' + @v 
     else if (len(@v) = 9 and CHARINDEX('9', @v) = 1) set @v = '6' + @v 
     -- impossible to do dynamic sql in function so... 
     if (@ci = 1) 
      update @tr set n1 = @v 
     else if (@ci = 2) 
      update @tr set n2 = @v 
     else if (@ci = 3) 
      update @tr set n3 = @v 
     else if (@ci = 4) 
      update @tr set n4 = @v 
     else if (@ci = 5) 
      update @tr set n5 = @v 
     set @ci = @ci + 1 
    end 
    return 
end 
go 

declare @t table (
    id nvarchar(10), 
    number nvarchar(30) 
) 

insert into @t (id, number) values 
    (N'ΠΕ000586', '2310836590'), 
    (N'ΠΕ000589', '2310.443602/6977.226818'), 
    (N'ΠΕ000633', '2310.288408/342456/6944.503637') 

select * from @t cross apply dbo.splitNums(number) 
go
