Find Stored Procedures referencing a table

Two ways:

SELECT o.object_id, o.name, m.definition
FROM sys.sql_modules m
INNER JOIN sys.objects o ON o.object_id = m.object_id
WHERE m.definition like '%tableName%'

SELECT p.name, c.text FROM syscomments c
JOIN sys.procedures p ON p.object_id=c.id
WHERE c.text LIKE '%tableName%'
ORDER BY p.name
