SQL唯一標識符是浮動

Question

我莫名其妙地堅持這一錯誤消息，我的痘痘查詢中

消息206，級別16，狀態2不兼容的37行 操作數類型衝突：唯一標識符是浮動不兼容

我已經嘗試設置uniqueidentifier的值是唯一標識符在他們的表中

或者將值設置爲0以進一步確定問題，但我沒有運氣。

USE [master]; 

    if OBJECT_ID('tempdb.dbo.powerdeviation') is not null 
    BEGIN 
    DROP TABLE tempdb.dbo.powerdeviation 
    END 


    DECLARE @factor decimal = '1,5' /* delete VALUE in workflow */ 
    DECLARE @item nvarchar(256) = '450294' /*delete Value in workflow */ 
    DECLARE @item2 nvarchar(256) = '450295' /*delete Value in workflow */

Answer 1

您可以執行下列操作之一：

選項1：在你的表定義，改變DEVICE_ID列 的DeviceID唯一標識符DEFAULT NEWID（） 有了這個，你不必指定DEVICE_ID插入時的值。它將自動使用NEWID（）函數並生成一個新的GUID。

選項2：在您的數據插入過程中，您可以像下面那樣調用以獲取Device_ID的新GUID。

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