SQL问题

对于存储过程输入，例如：

@CustomerID ='1,2,3,4，'
@Address ='Oregon'
@City ='Portland'

。我需要将值插入到单独的行中，如下所示：

    customerID | address city
 --------------+------------------
    1          |  Oregon Portland
    2          |  Oregon Portland
    3          |  Oregon Portland
    4          |  Oregon Portland

我需要有关如何在单个参数中插入CSV值以分隔行的帮助。

Answer 1

使用Jeff Moden的CSV分离器功能：

declare @CustomerId varchar(8000) = '1,2,3,4,'
      , @Address    varchar(64)   = 'Oregon' 
      , @City       varchar(64)   = 'Portland'

select 
    CustomerId = d.Item
  , Address = @Address
  , City = @City
from [dbo].[delimitedsplit8K](@CustomerId,',') as d
where d.Item <> ''

返回：

+------------+---------+----------+
| CustomerId | Address |   City   |
+------------+---------+----------+
|          1 | Oregon  | Portland |
|          2 | Oregon  | Portland |
|          3 | Oregon  | Portland |
|          4 | Oregon  | Portland |
+------------+---------+----------+

拆分字符串参考：

Answer 2

一种方法是递归CTE：

OnClickListener

Answer 3

使用while循环

WHILE len(@CustomerID) >1
BEGIN
insert into MyTable (customerID, Address, City)
values (left(@CustomerID, charindex(',',@CustomerID)), @Address, @City)

@CustomerID = substring(@CustomerID, 
                        charindex(',',@CustomerID)+1,
                        len(@CustomerID)-charindex(',',@CustomerID))

END

Answer 4

使用xQuery的有趣方式

declare @CustomerXML xml = '<i>' + replace(@CustomerID, ',', '</i><i>') + '</i>'

select 
    i.value('.', 'int') as customerID,
    @Address as address,
    @City as city
from @CustomerXML.nodes('for $i in /i where $i != "" return $i') as T(i)

Answer 5

我使用自定义的Table值Split函数，它在自定义指定的分隔符上拆分分隔的字符串，并在表变量中返回结果。

<div class="form-group has-feedback">
   <input type="text" class="form-control" placeholder="Phone Number" name="phone" value="{{ old('phone') }}"/>
   <span class="glyphicon glyphicon-phone form-control-feedback"></span>
</div>
