问题
Where can I find information about stored procedure parameters? In my situation I need to know only the input parameters of given store procedure.
In the sys.objects there is only common details about the procedure. In sys.sql_modules I can extract the whole SQL text of a procedure.
As (in SQL Server Management studio) I am able to extract information about the parameters in tabular view using ALT+F1 when selecting the procedure name. I hope there is some place from which I can extract input parameters details in that way.

select
'Parameter_name' = name,
'Type' = type_name(user_type_id),
'Length' = max_length,
'Prec' = case when type_name(system_type_id) = 'uniqueidentifier'
then precision
else OdbcPrec(system_type_id, max_length, precision) end,
'Scale' = OdbcScale(system_type_id, scale),
'Param_order' = parameter_id,
'Collation' = convert(sysname,
case when system_type_id in (35, 99, 167, 175, 231, 239)
then ServerProperty('collation') end)
from sys.parameters where object_id = object_id('MySchema.MyProcedure')
回答2:
select * from sys.parameters
inner join sys.procedures on parameters.object_id = procedures.object_id
inner join sys.types on parameters.system_type_id = types.system_type_id AND parameters.user_type_id = types.user_type_id
where procedures.name = 'sp_name'

There are the system tables, like sys.objects or sys.sysobjects.
Or you could also look at INFORMATION_SCHEMA, specifically INFORMATION_SCHEMA.ROUTINES and INFORMATION_SCHEMA.ROUTINE_COLUMNS.
Because it is in the ANSI-standard INFORMATION_SCHEMA, there are less SQL Server specific quirks. IMHO it is easier to understand for most things.

The following Query worked for me:
SELECT * FROM sys.parameters sp1, sys.procedures sp2 WHERE sp1.object_id = sp2.object_id
For more specific result with parameter order:
SELECT * FROM sys.parameters sp1, sys.procedures sp2, sys.types st WHERE sp1.object_id = sp2.object_id AND sp2.name = 'usp_nameofstoredprocedure' AND sp1.user_type_id = st.user_type_id ORDER BY sp1.parameter_id asc;
回答5:
It Contains a row for each parameter of an object that accepts parameters. If the object is a scalar function, there is also a single row describing the return value. That row will have a parameter_id value of 0.
SELECT *
FROM sys.parameters
WHERE object_id = object_id('SchemaName.ProcedureName')

For a supplied procedure name, the following query lists all of its parameters and their order along with their type and the type's length (for use with VARCHAR, etc.)
Replace procedure_name with the name of your procedure.
DECLARE @ProcedureName VARCHAR(MAX) = 'procedure_name'
SELECT
pa.parameter_id AS [order]
, pa.name AS [name]
, UPPER(t.name) AS [type]
, t.max_length AS [length]
FROM sys.parameters AS pa
INNER JOIN sys.procedures AS p on pa.object_id = p.object_id
INNER JOIN sys.types AS t on pa.system_type_id = t.system_type_id AND pa.user_type_id = t.user_type_id
WHERE p.name = @ProcedureName
回答7:
SELECT *
FROM INFORMATION_SCHEMA.PARAMETERS
WHERE SPECIFIC_NAME='proc_name'
ORDER BY ORDINAL_POSITION
(tested with MSSQL 2014)

Probably a little late , but since the search term Get parameters for all stored procedure on SQL on google, landed me this page, I will post that solution (which is also bit different from other answers in terms of join)
Select PROCS.name As StoredProcName,TYPE_NAME(user_type_id) As ParameterType,PARAMS.name As Params from sys.procedures PROCS
JOIN sys.parameters PARAMS WITH(NOLOCK) ON PROCS.object_id = PARAMS.object_id
Order by PROCS.object_id

Information Schemas are are ISO standard SQL. The PARAMETERS information schema view displays a list of parameters for user-defined functions and stored procedures in the current or specified database. This is one I use to get a list of all parameters for all procedures:
SELECT SPECIFIC_NAME, PARAMETER_MODE, PARAMETER_NAME, DATA_TYPE
FROM INFORMATION_SCHEMA.PARAMETERS
ORDER BY SPECIFIC_NAME
回答11:
select t1.[name] as [SP_name],t2.[name] as [Parameter_name],
t3.[name] as [Type],t2.[Length],t2.colorder as [Param_order]
from sysobjects t1
inner join syscolumns t2 on t1.[id]=t2.[id]
inner join systypes t3 on t2.xtype=t3.xtype
where t1.[name]='My_StoredProc_Name'
order by [Param_order]
