单独的逗号分隔值并存储在 sql server 的表中 [英] separate comma separated values and store in table in sql server

问题描述

我有一个存储过程，它获取逗号分隔值作为输入.我需要将它分开并需要将它作为单独的行存储在表中.

I am having a stored procedure which gets the comma separated value as an input. I need to separate it and needs to store it in a table as individual rows.

让 SP 的输入为:

Rule_ID  ListType_ID  Values
1        2            319,400,521,8465,2013

我需要将它存储在一个名为 DistributionRule_x_ListType 的表中，格式如下:

I need to store it in a table called DistributionRule_x_ListType in the below format:

Rule_ID  ListType_ID  Value
1        2            319
1        2            400
1        2            521
1        2            8465
1        2            2013

我的 SP 如下所示:

My SP looks like below:

ALTER PROCEDURE [dbo].[spInsertDistributionRuleListType]
(@Rule_ID int,
@ListType_ID int,
@Values VARCHAR(MAX)=NULL
)
AS
BEGIN

    INSERT INTO DistributionRule_x_ListType (Rule_ID,ListType_ID,Value)
    VALUES (@Rule_ID,@ListType_ID,@Values)

END

推荐答案

您将需要创建一个类似于此的拆分函数:

You will need to create a split function similar to this:

create FUNCTION [dbo].[Split](@String varchar(MAX), @Delimiter char(1))       
returns @temptable TABLE (items varchar(MAX))       
as       
begin      
    declare @idx int       
    declare @slice varchar(8000)       

    select @idx = 1       
        if len(@String)<1 or @String is null  return       

    while @idx!= 0       
    begin       
        set @idx = charindex(@Delimiter,@String)       
        if @idx!=0       
            set @slice = left(@String,@idx - 1)       
        else       
            set @slice = @String       

        if(len(@slice)>0)  
            insert into @temptable(Items) values(@slice)       

        set @String = right(@String,len(@String) - @idx)       
        if len(@String) = 0 break       
    end   
return 
end;

然后在您的存储过程中，您将调用该函数来拆分您的字符串:

Then in your stored procedure, you will call the function to split your string:

ALTER PROCEDURE [dbo].[spInsertDistributionRuleListType]
(
  @Rule_ID int,
  @ListType_ID int,
  @Values VARCHAR(MAX)=NULL
)
AS
BEGIN

    INSERT INTO DistributionRule_x_ListType (Rule_ID, ListType_ID, Value)
    SELECT @Rule_ID, @ListType_ID, items
    FROM [dbo].[Split] (@Values, ',')  -- call the split function 

END

当您执行存储过程时，它将拆分值并将多行插入到您的表中:

When you execute the stored procedure, it will split the values and insert the multiple rows into your table:

exec spInsertDistributionRuleListType 1, 2, '319,400,521,8465,2013';

请参阅SQL Fiddle with Demo.这将插入以下结果:

See SQL Fiddle with Demo. This will insert the following result:

| RULE_ID | LISTTYPE_ID | VALUE |
---------------------------------
|       1 |           1 |    10 |
|       1 |           2 |   319 |
|       1 |           2 |   400 |
|       1 |           2 |   521 |
|       1 |           2 |  8465 |
|       1 |           2 |  2013 |
