SYMPTOMS

In a Microsoft SQL Server 2005 merge replication, you drop a foreign key constraint on a table at the publisher. After you synchronize the data between the publisher and the subscriber, the replication merge agent does not drop the foreign key constraint on the table at the subscriber.

This problem occurs when the related tables at the publisher and at the subscriber do not belong to the dbo schema.

Back to the top

CAUSE

This problem occurs because the replication merge agent runs an incorrect query at the subscriber. When the replication merge agent runs the query, the OBJECT_ID function returns NULL. Then, the IF EXISTS statement returns FALSE. Therefore, the replication merge agent does not run the DROP CONSTRAINT statement.

The following is an example of the query that the replication merge agent runs at the subscriber:
IF EXISTS (SELECT * from sysconstraints WHERE constid = OBJECT_ID (N'[FK_DETAIL_TO_MASTER]')) 
IF OBJECT_ID (N'[Test].[Detail]') IS NOT NULL 
EXEC ('ALTER TABLE [Test].[Detail] DROP CONSTRAINT FK_DETAIL_TO_MASTER')

MORE INFORMATION

Steps to reproduce the problem

1.Create two tables by using a schema that is not a dbo schema.
2.Create a foreign key constraint on a table to reference a column in another table.

Note When you create the foreign key constraint, the foreign key constraint is created by using a schema that is not a dbo schema.
3.Publish both tables.

Note When you publish the tables, make sure that you perform the following operations:
•Specify that the primary key constraint and the foreign key constraint are to be copied to the subscribers.
•Specify that the Destination object owner property of the articles is to be an owner other than the dbo user.
4.Initialize a subscription.
5.Drop the foreign key constraint on the publisher.
6.Run the merge agent to synchronize the data between the publisher and the subscriber.
