I have
a Win Form, Data Entry, application that uses 4 seperate Data Bases. This is an occasionally connected app that uses Merge Replication (SQL 2005) to stay in Sync. This is working just fine. The next hurdle I am trying to tackle is adding Filters to my Publications.
Right now we are replicating 70mbs, compressed, to each of our 150 subscribers when, truthfully, they only need
a tiny fraction of that. Using Filters I am able to accomplish this(see code below) but I had to make
a mapping table in order to do so. This mapping table consists of 3 columns.
A PrimaryID(Guid), WorkerName(varchar),
and ClientID(int).
The problem is I need this table present in all FOUR Databases in order to use it for the filter since, to my knowledge, views or cross-db query's are not allowed in
a Filter Statement.
What are my options?
Seems like I would set it up to be maintained in 1 Database
and then use Triggers to keep it updated in the other 3 Databases. In order to be
a part of the Filter I have to include that table in the Replication Set so how do I flag it appropriately.
Is there
a better way, altogether?
SELECT <published_columns> FROM [dbo].[tblPlan] WHERE [ClientID] IN (select ClientID from [dbo].[tblWorkerOwnership] where WorkerID = SUSER_SNAME())
Which allows you to chain together Filters, this next one is below the first one so it only pulls from the first's Filtered Set.
SELECT <published_columns> FROM [dbo].[tblPlan] INNER JOIN [dbo].[tblHealthAssessmentReview] ON [tblPlan].[PlanID] = [tblHealthAssessmentReview].[PlanID]
