我正在尝试执行我通过用于Microsoft Visio的Forward Engineer Addin创建的数据库脚本。
以下是我收到的错误以及错误消息引用的代码部分:
错误1:
Msg 1776, Level 16, State 0, Line 12
There are no primary or candidate keys in the referenced table 'dbo.Account_BillingAccount' that match the referencing column list in the foreign key 'Account_BillingAccount_InvoiceDetail_FK1'.
Msg 1750, Level 16, State 0, Line 12
Could not create constraint. See previous errors.
代码参考1:
ALTER TABLE [dbo].[InvoiceDetail] WITH CHECK ADD CONSTRAINT [Account_BillingAccount_InvoiceDetail_FK1] FOREIGN KEY (
[BillingAccountNumber]
, [AccountNumber]
)
REFERENCES [dbo].[Account_BillingAccount] (
[BillingAccountNumber]
, [AccountNumber]
)
错误2:
Msg 1776, Level 16, State 0, Line 2
There are no primary or candidate keys in the referenced table 'dbo.ManagerContract' that match the referencing column list in the foreign key 'ManagerContract_RegionalCoordinators_FK1'.
Msg 1750, Level 16, State 0, Line 2
Could not create constraint. See previous errors.
代码参考2:
ALTER TABLE [dbo].[RegionalCoordinators] WITH CHECK ADD CONSTRAINT [ManagerContract_RegionalCoordinators_FK1] FOREIGN KEY (
[AssociateID]
, [WritingNumber]
)
REFERENCES [dbo].[ManagerContract] (
[AssociateID]
, [WritingNumber]
)
删除上述错误的最有效方法是什么?
答案 0 :(得分:0)
您必须在引用的表中具有与列列表匹配的主键或唯一键。因此,ManagerContract
AssociateID, WritingNumber
Account_BillingAccount
需要BillingAccountNumber, AccountNumber
上的alter table dbo.ManagerContract
add constraint UNQ_ManagerContract_AssociateID_WritingNumber
unique (AssociateID, WritingNumber)
需要一个唯一键。{/ 1}}
在这里查看如何创建唯一约束。 http://msdn.microsoft.com/en-us/library/ms191166.aspx
ALTER TABLE [dbo]。[TableName] ADD CONSTRAINT UNQ_ TableName _ColumnName UNIQUE([ColumnName])
你的情况就是这样。
