Ovanstående hittar alla referenser inom varje databas, men kommer inte att hitta korsdatabasreferenser. Det tog lite att spela och resultatet är inte exakt vad du ville ha, men jag tror att det gör det mer självförklarande:

DECLARE @table_name SYSNAME = N'%'; -- find all



CREATE TABLE #d
(
    db SYSNAME, 
    [object_id] INT, 
    sch SYSNAME,
    obj SYSNAME,
    ref_db NVARCHAR(128),
    ref_sch NVARCHAR(128), 
    ref_obj NVARCHAR(128),
    ref_object_id INT,
    type_desc SYSNAME
);

DECLARE @sql NVARCHAR(MAX) = N'';

SELECT @sql += 'SELECT ''' + QUOTENAME(name) + ''',
    d.referencing_id,
    QUOTENAME(s.name),
    QUOTENAME(o.name),
    QUOTENAME(d.referenced_database_name),
    QUOTENAME(d.referenced_schema_name),
    QUOTENAME(d.referenced_entity_name),
