Search all objects(Trigger,Store Procedure,Rule,Constraint etc) in a database containing a certain string

search all objects in a database containing a certain string, in my case a reference to another database. This example makes it possible to find all references in triggers and stored procedures etc:

SELECT DISTINCT o.name AS ObjectName,

CASE o.xtype

WHEN 'C' THEN 'CHECK constraint'

WHEN 'D' THEN 'Default or DEFAULT constraint'

WHEN 'F' THEN 'FOREIGN KEY constraint'

WHEN 'FN' THEN 'Scalar function'

WHEN 'IF' THEN 'In-lined table-function'

WHEN 'K' THEN 'PRIMARY KEY or UNIQUE constraint'

WHEN 'L' THEN 'Log'

WHEN 'P' THEN 'Stored procedure'

WHEN 'R' THEN 'Rule'

WHEN 'RF' THEN 'Replication filter stored procedure'

WHEN 'S' THEN 'System table'

WHEN 'TF' THEN 'Table function'

WHEN 'TR' THEN 'Trigger'

WHEN 'U' THEN 'User table'

WHEN 'V' THEN 'View'

WHEN 'X' THEN 'Extended stored procedure'

ELSE o.xtype

END AS ObjectType,

ISNULL( p.Name, '[db]') AS Location

FROM syscomments c

INNER JOIN sysobjects o ON c.id=o.id

LEFT JOIN sysobjects p ON o.Parent_obj=p.id

WHERE c.text LIKE '%_%'

ORDER BY Location, ObjectName
