Another in the potentially quite sporadic series of I need to do ... but I cant find it on the internet.
I have a table that I think might be involved in replication but I don't know which publication its in...
We know the table name - 'MyTable'
We have replication running on our server and its replicating our database, or part of it - 'MyDatabase'.
We need to know if the table is replicated and if so which publication is going to need to be reviewed if we make changes to the table.

How?

USE MyDatabase
GO
/* Lots of info about our table but not much that's relevant to our current requirements*/
SELECT * FROM sysobjects
WHERE NAME = 'MyTable'
-- mmmm, getting there
/* To quote BOL - "Contains one row for each merge article defined in the local database. This table is stored in the publication database.replication"
interesting column is [pubid]
*/
SELECT * FROM dbo.sysmergearticles AS s
WHERE NAME = 'MyTable'
-- really close now
/*
the sysmergepublications table - Contains one row for each merge publication defined in the database. This table is stored in the publication and subscription databases.
so this would be where we get the publication details
*/
SELECT * FROM dbo.sysmergepublications AS s
WHERE s.pubid = '2876BBD8-3D4E-4ED8-88F3-581A659E8144'
-- DONE IT.
/*
Combine the two tables above and we get the information we need
*/
SELECT s.[name] AS [Publication name] FROM dbo.sysmergepublications AS s
INNER JOIN dbo.sysmergearticles AS s2 ON s.pubid = s2.pubid
WHERE s2.NAME = 'MyTable'

So I now know which
