How to replication a table without a primary key?
When we try to add an article to the transactional replication ( sp_addarticle ) for the table without a primary key we get this error: This Microsoft documentation describes replication article types.
Are there any limitations to transactional replication in SQL?
The best solution in our case is transactional replication, but there are some limitations though. The source database is used by a third-party application. Some tables have clustered and/or unique indexes, but the database doesn’t have primary keys. We can’t make changes to the existing objects, but we can create new ones.
How to replicate a table in SQL Server?
Create a subscription. To replicate the data using indexed views we will need to use the sp_addarticle stored procedure with @type parameter set to the “indexed view logbased”. SSMS only creates articles for the views with “indexed view schema only” type.
Can you run MySQL dump without locking tables?
Honestly, I would setup replication for this, as if you don’t lock tables you will get inconsistent data out of the dump. If the dump takes longer time, tables which were already dumped might have changed along with some table which is only about to be dumped. So either lock the tables or use replication.
Do you need a primary key for Merge Replication?
All tables should have a primary key when they are created, but sometimes this is not addressed and for replication to work this needs to be setup. In addition, if you are using merge replication you need to have a RowGuid column. Also, if you use identity columns you need to make sure the not for replication parameter is turned on .
How to enforce not for replication in Transact-SQL?
Right-click the foreign key constraint and then click Modify. In the Foreign Key Relationships dialog box, select a value of No for Enforce For Replication. Click Close. To perform this task in Transact-SQL, drop the foreign key constraint. Then add a new foreign key constraint and specify the NOT FOR REPLICATION option.
Why are foreign key constraints disabled in replication?
The constraint is disabled for the replication agent because the constraint was already checked at the Publisher when the data was originally inserted, updated, or deleted. Requires ALTER permission on the table.
