sql server - How to Query 2 SQL databases and compare results -

i have 2 separate sql server databases i'd query , compare results.

for example:

db1

select *  customers  dtcreated > @startdate

this query give me list of customers created after specific date.

i take results above, , query database (db2) tell me of above query customers still active.

something like:

db2

select *  customers bactive = 'true'       (and exists in db1 query)

is there way this?

output:

number of records db1            number active in db2         155                                   67

you can cross-database queries specifying databasename , schema + table name.

select *  customers b bactive = 'true' , exists (select 'x'  database1.dbo.customers a.dtcreated > @startdate , a.key = b.key)

i'm sorry i'm bit confused example querys , example output. using technique can count way like
