c# - SQL Server : conversion failed when converting from a character string to uniqueidentifier

Question

我正在尝试将表导入 SQL Server 并执行以下语句:

INSERT INTO [schemes] 
VALUES('3510C197C4043E419C8F01E0C62FA978', 1, 'AS2', null, 
       '2009-04-21 12:52:00.000', '2009-04-21 12:52:00.000');

我遇到异常

Conversion failed when converting from a character string to uniqueidentifier

谁能帮我解决这个问题吗？

Answer 1

尝试以正确的格式将其转换为 UNIQUEIDENTIFIER，例如:

DECLARE @uuid VARCHAR(50)
DECLARE @gid UNIQUEIDENTIFIER

SET @uuid = '3510C197C4043E419C8F01E0C62FA978'
SELECT @gid = CAST(
        SUBSTRING(@uuid, 1, 8) + '-' + SUBSTRING(@uuid, 9, 4) + '-' + SUBSTRING(@uuid, 13, 4) + '-' +
        SUBSTRING(@uuid, 17, 4) + '-' + SUBSTRING(@uuid, 21, 12)
        AS UNIQUEIDENTIFIER)

然后在其后面插入该值

insert into [schemes] 
values(@gid, 1, 'AS2', null, '2009-04-21 12:52:00.000', '2009-04-21 12:52:00.000');
