我試圖在固定長度列中插入數據,但是出現錯誤。在固定長度列sql服務器中插入數據
表看起來是這樣的:
CREATE TABLE [dbo].[zam_pcinfo](
[Id] [decimal] identity NOT NULL,
[employe_name] [nvarchar](50) NOT NULL,
[location_id] [decimal] NOT NULL,
[department_id] [decimal] NOT NULL,
[computer_name] [nvarchar](25) NOT NULL,
[user_name] [nvarchar](25) NOT NULL,
[teamviewer_id] [nvarchar](25) NULL check (DATALENGTH(teamviewer_id) = 9),
[lan_ip] [nvarchar](20) NULL,
[policy] [nvarchar](25) NOT NULL,
[os] [nvarchar](25) NOT NULL,
[pctype] [nvarchar](25) NOT NULL,
[note] [nvarchar](50) NULL,
[password] [nvarchar](25) NOT NULL,
[tmngr] [bit] NOT NULL,
[type_user] [nvarchar] (25) Not null,
[w-internal-mac-address] [nvarchar](50) null)
我使用DATALENGTH
功能teamviewer_id
列,當我試圖將數據插入到該列就顯示了這個錯誤:
insert statement is conflict with check constraint "nameoftheconstraint" the conflict occurred in database "nameofdatabase", table "nameoftable" column
teamviewer_id
燦你幫助我嗎?檢查約束在這種情況下是否正確?
哪些數據是你想插入teamviewer_id列?違反約束的例外情況表明數據長度不是9個字符。 – Andrew
你需要'LEN'嗎? – Milen
當您將長度限制爲9時,爲什麼要使用VARCHAR(25)? – dnoeth
