The catalog view sys.sql_expression_dependencies gets you close. For example:

SELECT 
  [A view] = s.name + '.' + v.name, 'references',
  [B object] = d.referenced_database_name + '.' 
             + d.referenced_schema_name + '.' 
             + d.referenced_entity_name
FROM DatabaseA.sys.views AS v
INNER JOIN DatabaseA.sys.schemas AS s
ON v.[schema_id] = s.[schema_id]
INNER JOIN DatabaseA.sys.sql_expression_dependencies AS d
ON v.[object_id] = d.[referencing_id]
WHERE d.referenced_database_name = N'DatabaseB';


It does not provide column names, however.

Unfortunately other catalog views like sql_dependencies are unreliable for this kind of thing, since they don't follow dependencies outside the scope of the current database. And it's deprecated anyway. However there are more reliable views, like sys.dm_sql_referenced_entities:

SELECT 
  [A view] = s.name + '.' + v.name, 'references',
  [B column] = r.referenced_database_name + '.'
             + r.referenced_schema_name + '.'
             + r.referenced_entity_name + '.'
             + r.referenced_minor_name         
FROM DatabaseA.sys.views AS v
INNER JOIN DatabaseA.sys.schemas AS s
ON v.[schema_id] = s.[schema_id]
CROSS APPLY DatabaseA.sys.dm_sql_referenced_entities
(
  QUOTENAME(s.name) + '.' + QUOTENAME(v.name), N'OBJECT'
) AS r
WHERE r.referenced_minor_id &gt; 0
AND r.referenced_database_name = N'DatabaseB';

Troubleshooting SQL Dependencies


Also understand that dependencies are hard, they've changed the approach several times since SQL Server 2000, and we've had a long history of employing workarounds to ensure that the information is current and consistent (but still tend to fail on a regular basis).
