How to change Foreign Key name?
I am currently creating new tables in my SQL Server database. I am renaming the开发者_StackOverflow中文版 old tables, so also the foreign key constraints.
To use the Adventureworks DB as an example the SalesOrderDetail table has FK_SalesOrderDetail_SalesOrderHeader_SalesOrderId (which links to the SalesOrderHeader table).
Is is changing the name of this foreign key sufficient or do I also need to change the foreign key reference in the SalesOrderHeader Table?
Just the name - it won't change the relationship in any way.
EXEC sp_rename 'Sales.FK_SalesOrderDetail_SalesOrderHeader_SalesOrderId',
'new_name',
'OBJECT';
NB: That foreign key in AdventureWorks is in the Sales
schema so the object_name
argument is schema qualified in the procedure call above.
SELECT Object_name(constraint_object_id),
Object_name(parent_object_id),
(SELECT name
FROM sys.columns
WHERE object_id = parent_object_id
AND column_id = parent_column_id),
Object_name(referenced_object_id),
(SELECT name
FROM sys.columns
WHERE object_id = referenced_object_id
AND column_id = referenced_column_id),
'sp_rename ''' + Object_name(constraint_object_id) + ''', ''con_fk_' + (SELECT Lower(name)
FROM sys.columns
WHERE object_id = parent_object_id
AND column_id = parent_column_id) + ''',''OBJECT'''
FROM sys.foreign_key_columns
