表

Column A        Column B        Column C
----------------------------------------------

我有一个输入字符串，如（Apple，Banana，Orange）。我需要将这些值插入上表。

结果应该是

ColumnA     Column B        Column C
-------------------------------------------
Apple       Banana          Orange

是否可以使用将输入参数作为csv字符串的过程？

Answer 1

请使用以下代码获取列名列表。您可以将其传递给SP以插入到您的表格中。

BEGIN
          DECLARE @str VARCHAR(2000)
          DECLARE @input VARCHAR(4000)
          DECLARE @ind Int
          DECLARE @Count int 
          DECLARE @max int 
          SET @max =0
          DECLARE @table TABLE(ColumnA varchar(10),ColumnB varchar(10),ColumnC varchar(10))
          DECLARE @Result TABLE (ID int identity(1,1),value varchar(1000))
          SET @input ='Apple,Banana,Orange'
          IF(@input is not null)
              BEGIN
                    SET @ind = CharIndex(',',@input)
                    WHILE @ind > 0
                        BEGIN
                              SET @str = SUBSTRING(@input,1,@ind-1)
                              SET @input = SUBSTRING(@input,@ind+1,LEN(@input)-@ind)
                              INSERT INTO @Result values (@str)
                              SET @ind = CharIndex(',',@input)
                        END
              SET @str = @input
              INSERT INTO @Result values (@str)
             END

          SET @Count = (SELECT Max(ID) from @Result)

             WHILE @Count > @max
              BEGIN
               SET @max = @max +1
               DECLARE @Value varchar(1000)
               SET @Value = (SELECT value from @Result WHERE ID =@max)

               SELECT @value
             END
    END

请检查以下SQL脚本，该脚本将输入字符串参数拆分并插入表

请注意我使用SQL split string function dbo.Split，你可以在推荐的SQL教程中找到源代码

除非使用SQL Server 2016

，否则您将需要这样的用户定义拆分功能

/*
create table TableT (
[Column A] varchar(100),
[Column B] varchar(100),
[Column C] varchar(100)
)
*/
declare @string varchar(max) = 'Apple,Banana,Orange'
select * from dbo.Split(@string, ',')

insert into TableT
select
    MAX([Column A]) as [Column A],
    MAX([Column B]) as [Column B],
    MAX([Column C]) as [Column C]
from (
select
    case when id = 1 then val end as [Column A],
    case when id = 2 then val end as [Column B],
    case when id = 3 then val end as [Column C]
from dbo.Split(@string, ',')
) s

select * from TableT

Answer 3

请使用以下查询。它在SQL Server 2012中运行良好。

char

用逗号读取字符串并插入到sql表的单行中
