How to count all stored procedures in the SQL Server for a database?

select Count(*) from sys.procedures

And as Philip Kelley noted this is sql 2005 and up

-- Information about table -- 
SELECT * FROM sys.sysobjects WHERE xtype = 'U'

-- Information about Stored Procedure --
SELECT * FROM sys.sysobjects WHERE xtype = 'P'

-- Information about Functions --
SELECT * FROM sys.sysobjects WHERE xtype = 'FN'

-- Information about Views --
SELECT * FROM sys.sysobjects WHERE xtype = 'V'

To get the Stored Procedure count:

SELECT COUNT(*) SPCOUNT 
  FROM INFORMATION_SCHEMA.ROUTINES
 WHERE ROUTINE_TYPE='PROCEDURE'

or:

SELECT COUNT(*)
  FROM sys.procedures

or:

SELECT COUNT(*) 
  FROM sys.sysobjects
 WHERE xtype = 'P'

Hope one of these help.
