Here is some T-SQL I got from a friend of mine (David Mccoullgh). Just set the @SearchPhrase to search across stored proc, functions, triggers to see where that string is in use. Very helpful if you are changing a field name and want to know where it is in use.
DECLARE @SearchPhrase varchar(1000)
SET @SearchPhrase = 'PlayerBonus'
SELECT DISTINCT sysobjects.name AS [Object Name],
case
when sysobjects.xtype = 'P' then 'Stored Proc'
...
