How to check if database exist on Remote Server through SQL query

Question

I have a table as following in SQL Server 2012.

|---------------------|------------------|------------------|
|      ClientName     |     servername   |Datab         


        

Answer 1

Is there a way to return only rows for which database exists on the server names mentioned in the table?

I want it to be part of where clause.

If I understand your question correctly, you can use where exists

e.g. (you need to have server1 as linked server from the server that you are running the query from)

select * from 
schema.yourTable
where exists (select 1 from Server1.dbname.schemaName.yourServerList
                 where DatabaseName = 'b1')
