SQL唯一标识符是浮动

Question

我莫名其妙地坚持这一错误消息，我的痘痘查询中

消息206，级别16，状态2不兼容的37行 操作数类型冲突：唯一标识符是浮动不兼容

我已经尝试设置uniqueidentifier的值是唯一标识符在他们的表中

或者将值设置为0以进一步确定问题，但我没有运气。

您可以执行下列操作之一：

选项1：在你的表定义，改变DEVICE_ID列 的DeviceID唯一标识符DEFAULT NEWID（） 有了这个，你不必指定DEVICE_ID插入时的值。它将自动使用NEWID（）函数并生成一个新的GUID。

选项2：在您的数据插入过程中，您可以像下面那样调用以获取Device_ID的新GUID。

INSERT INTO <table> VALUES (....., NEWID() as Device_ID....)
