如何将 01,02,03 之类的列分隔为 SQL 中的行？

Question

CREATE TABLE Tabx_Test_Import
(
    ID        INT NOT NULL IDENTITY(1, 1),
    Week      NVARCHAR(2000),
    Code      NVARCHAR(20),
    Amount    NUMERIC(19, 6),
    Name      NVARCHAR(50),
    Last_Name NVARCHAR(50),
    RC        NVARCHAR(11)
) ON [PRIMARY]

CREATE TABLE Tabx_Test_Inz
(
    ID     INT NOT NULL IDENTITY(1, 1),
    Week   INT NOT NULL,
    RC     NVARCHAR(10),
    Code   NVARCHAR(20),
    Amount NUMERIC(19, 6),
) ON [PRIMARY]

INSERT INTO Tabx_Test_Import (Week, Code, Amount, Name, Last_Name, RC)
VALUES (N'01,02,03', N'012016A15', 11.50, N'Juraj', N'Novotný', N'050671/8652')

INSERT INTO Tabx_Test_Import (Week, Code, Amount, Name, Last_Name, RC)
VALUES (N'04,05,08', N'012016G45', 22.30, N'Peter', N'Pýchly', N'030888/3553')

INSERT INTO Tabx_Test_Import (Week, Code, Amount, Name, Last_Name, RC)
VALUES (N'10,11,12,13', N'012016A18', 8.70, N'Juraj', N'Novotný', N'050671/8652')

INSERT INTO Tabx_Test_Import (Week, Code, Amount, Name, Last_Name, RC)
VALUES (N'04,05,06', N'012016T66', 12.12, N'Peter', N'Pýchly', N'030888/3553')

INSERT INTO Tabx_Test_Import (Week, Code, Amount, Name, Last_Name, RC)
VALUES (N'04', N'012016H11', 55.00, N'Peter', N'Pýchly', N'030888/3553')

每周将在一行中 - 导入 table 周数的记录必须被打破，因为代码和客户需要这么多行用逗号分隔多少周。

表示一个星期，一个客户，一个代码在一行。

INSERT INTO Tabx_Test_Inz  (Week, RC, Code, Amount) 
    SELECT 
        SUBSTRING(Week,1,2), 
        REPLACE(RC,'/','') , Code, Amount
    FROM
        Tabx_Test_Import;

INSERT INTO Tabx_Test_Inz  (Week, RC, Code, Amount) 
    SELECT 
        SUBSTRING(Week,4,2), 
        REPLACE(RC,'/','') , Code, Amount
    FROM 
        Tabx_Test_Import;

INSERT INTO Tabx_Test_Inz  (Week, RC, Code, Amount) 
    SELECT 
        SUBSTRING(Week,7,2), 
        REPLACE(RC,'/','') , Code, Anount
    FROM 
        Tabx_Test_Import;

INSERT INTO Tabx_Test_Inz  (Week, RC, Code, Amount)
    SELECT
        SUBSTRING(Week,10,2),
        REPLACE(RC,'/','') , Code, Amount
    FROM 
        Tabx_Test_Import;

我已经试过了...但是不正确。

您似乎想为周的每个不同值插入相同的行，您可以使用 string_split 来实现此目的：

 insert into Tabx_Test_Inz (Week, RC, Code, Amount)
 select value, replace(RC,'/',''), code, amount
 from Tabx_Test_Import
 cross apply String_Split(week,',')
