Question

我写了下面的代码。它无法正常工作

INPUT

A,B,C,D

QUERY（我到目前为止已尝试过）

Declare @products nvarchar(max)='A,B,C,D'
Declare @individual nvarchar(max)

Declare @Jurisdiction table
(
     JurisdictionX nvarchar(max)
)
WHILE LEN(@products) > 0
BEGIN
    IF PATINDEX('%,%',@products) > 0
    BEGIN
        SET @individual = SUBSTRING(@products, 0, PATINDEX('%,%',@products))
        SELECT @individual

        SET @products = SUBSTRING(@products, LEN(@individual + ',') + 1,
                                                     LEN(@products))
    END

    ELSE
    BEGIN
       SET @individual = @products
       SET @products = NULL
       Insert into @Jurisdiction values(@individual);
    END
END

Select * from @Jurisdiction;

渴望输出

COLS
.....
 A
 B
 C
 D

我想执行插入操作。它无法正常工作

Answer 1

好像你没有指定列名：JurisdictionX

试试这个：Insert into @Jurisdiction(JurisdictionX) values(@individual);

Answer 2

我认为您正在尝试将Comma Separated Values插入行。

为此您可以使用此查询

DECLARE @STR NVARCHAR(MAX)='A,B,C,D'

SELECT PARSENAME(REPLACE(Split.a.value('.', 'VARCHAR(100)'),',','.'),1) 'Ids' 
FROM  
(
     -- Select the string in XML format
     SELECT CAST ('<M>' + REPLACE(@STR, ',', '</M><M>') + '</M>' AS XML) AS Data         
) AS A 
CROSS APPLY Data.nodes ('/M') AS Split(a)

的 SQL FIDDLE

更新：根据OP提供的代码

Declare @products nvarchar(max)='A,B,C,D' Declare @individual nvarchar(max) Declare @Jurisdiction table ( JurisdictionX nvarchar(max) ) WHILE LEN(@products) > 0 BEGIN IF PATINDEX('%,%',@products) > 0 BEGIN SET @individual = SUBSTRING(@products, 0, PATINDEX('%,%',@products)) SELECT @individual SET @products = SUBSTRING(@products, LEN(@individual + ',') + 1, LEN(@products)) END ELSE BEGIN SET @individual = @products SET @products = NULL Insert into @Jurisdiction values(@individual); END END Select * from @Jurisdiction;

逗号将值分隔为行
