This is really handy, but I wanted a way to show all user objects, not just tables, so I adapted it to use sys.objects instead of sys.tables
SET NOCOUNT ON
DECLARE @AllTables table (DbName sysname,SchemaName sysname, ObjectType char(2), ObjectName sysname)
DECLARE
@SearchDb nvarchar(200)
,@SearchSchema nvarchar(200)
,@SearchObject nvarchar(200)
,@SQL nvarchar(4000)
SET @SearchDb='%'
SET @SearchSchema='%'
SET @SearchObject='%Something%'
SET @SQL='select ''?'' as DbName, s.name as SchemaName, t.type as ObjectType, t.name as ObjectName
from [?].sys.objects t inner join sys.schemas s on t.schema_id=s.schema_id
WHERE t.type in (''FN'',''IF'',''U'',''V'',''P'',''TF'')
AND ''?'' LIKE '''+@SearchDb+'''
AND s.name LIKE '''+@SearchSchema+'''
AND t.name LIKE '''+@SearchObject+''''
INSERT INTO @AllTables (DbName, SchemaName, ObjectType, ObjectName)
EXEC sp_msforeachdb @SQL
SET NOCOUNT OFF
SELECT * FROM @AllTables ORDER BY DbName, SchemaName, ObjectType, ObjectName
