从字符串转换为uniqueidentifier sql时转换失败

Question

我创建了一个具有以下属性的表：

CREATE TABLE [a02].[property] 
(
    propertyID UNIQUEIDENTIFIER PRIMARY KEY DEFAULT newsequentialid(),
    propertyTitle VARCHAR(100) NOT NULL,
    residenceName VARCHAR(100) NOT NULL,
    residenceStreet VARCHAR(100) NOT NULL,
    postCode VARCHAR(100) NOT NULL,
    bedroomCount INT NOT NULL,
    bathroomCount INT NOT NULL,
    garageCarCount INT NOT NULL,
    internalSqMetres FLOAT NOT NULL,
    outdoorSqMetres FLOAT NOT NULL,
    askingPrice FLOAT NOT NULL,
    sellingPrice FLOAT,
    registeredDate DATE NOT NULL,
    soldDate DATE,
    localityID UNIQUEIDENTIFIER NOT NULL
            REFERENCES [a02].[locality] (localityID),
    typeID UNIQUEIDENTIFIER NOT NULL
            REFERENCES [a02].[propertyType] (typeID),
    accountID UNIQUEIDENTIFIER NOT NULL
            REFERENCES [a02].[userAccount] (accountID)
);

我正在插入以下记录：

INSERT INTO [a02].[property] (propertyTitle, residenceName, residenceStreet, 
                              postCode, bedroomCount, bathroomCount, garageCarCount,             
                              internalSqMetres, outdoorSqMetres, askingPrice, sellingPrice,         
                              registeredDate, soldDate, localityID, typeID, accountID)
VALUES ('Ground Floor Maisonette Fgura', '10', 'Triq il-Kbira', 
        'FGR2000', 3, 1.5, 2, 
        130, 50, 250000, 235000, 
        '11/13/2018', '11/13/2018', 
        (SELECT localityName FROM [a02].[locality] 
         WHERE localityName = 'Il-Fgura'), 
        (SELECT typeName FROM [a02].[propertyType] 
         WHERE typeName ='Maisonette'), 
        (SELECT accountID FROM [a02].[userAccount] 
         WHERE accountUsername = 'joeb')),
      ('First Floor Floor Maisonette Fgura', '10', 'Triq il-Kbira', 
       'FGR2000', 3, 1.5, 2, 
       130, 50, 350000, 335000, '11/13/2018', '11/13/2017', 
       (SELECT localityName FROM [a02].[locality] 
        WHERE localityName = 'Il-Fgura'), 
       (SELECT typeName FROM [a02].[propertyType] 
        WHERE typeName = 'Maisonette'), 
       (SELECT accountID FROM [a02].[userAccount] 
        WHERE accountUsername ='joeb')),
      ('Ground Floor Maisonette Mosta', '20', 'Triq il-Qamh', 
       'MST1000', 4, 2, 2, 
       150, 50, 275000, NULL, '11/13/2018', NULL, 
       (SELECT localityName FROM [a02].[locality] 
        WHERE localityName = 'Il-Mosta'), 
       (SELECT typeName FROM [a02].[propertyType] 
        WHERE typeName = 'Maisonette'), 
       (SELECT accountID FROM [a02].[userAccount] 
        WHERE accountUsername = 'lisaA')),
      ('Penthouse Zabbar', '5', 'Triq il-Passa',  
       'ZBR1050', 3, 1, 1, 
       150, 50, 300000, NULL, '11/13/2018', NULL, 
       (SELECT localityName FROM [a02].[locality] 
        WHERE localityName = 'Haz-Zabbar'),
       (SELECT typeName FROM [a02].[propertyType] 
        WHERE typeName = 'Penthouse'), 
       (SELECT accountID FROM [a02].[userAccount] 
        WHERE accountUsername ='joeb'));

我收到此错误：

从字符串转换为唯一标识符时转换失败

它标记了这条线：

INSERT INTO [a02].[property] (propertyTitle, residenceName,residenceStreet, postCode, bedroomCount, bathroomCount, garageCarCount, internalSqMetres, outdoorSqMetres, askingPrice, sellingPrice, registeredDate, soldDate, localityID, typeID, accountID)

有什么线索吗？

Answer 1

在插入语句中使用以下查询将字符串值转换为唯一标识符。

字符串值应该 >= 33。如果 > 33 则只需要 33 个字符

SELECT  CAST(
        SUBSTRING(<ColName>, 1, 8) + '-' + SUBSTRING(<ColName>, 9, 4) + '-' + SUBSTRING(<ColName>, 13, 4) + '-' +
        SUBSTRING(<ColName>, 17, 4) + '-' + SUBSTRING(<ColName>, 21, 12)
        AS UNIQUEIDENTIFIER)

会是这样的

INSERT INTO [a02].[property] (
      propertyTitle
      , residenceName
      , residenceStreet
      , postCode
      , bedroomCount
      , bathroomCount
      , garageCarCount
      , internalSqMetres
      , outdoorSqMetres
      , askingPrice
      , sellingPrice
      , registeredDate
      , soldDate
      , localityID
      , typeID
      , accountID
      )

      'Ground Floor Maisonette Fgura'
      , '10'

      , 1.5
      , 2
      , 130

        SUBSTRING(localityName, 17, 4) + '-' + SUBSTRING(localityName, 21, 12)
        AS UNIQUEIDENTIFIER)
            FROM [a02].[locality]
