Add sp parameter sql server without modifying the stored procedure request - sql-server

Question

I have a sample stored procedure named SPExample .
I want to add a parameter named TestParam to this stored procedure without using this syntax
Alter PROCEDURE SPExample
#TestParamint
AS
BEGIN
...
END
Is there a syntax like: Alter PROCEDURE SPExample Add parameter ... or any other alternative?

Short answer:
NO you can not
Detailed answer:
Alter procedure has 3 different syntax as below:
SQL Server Syntax:
ALTER { PROC | PROCEDURE } [schema_name.] procedure_name [ ; number ]
[ { #parameter [ type_schema_name. ] data_type }
[ VARYING ] [ = default ] [ OUT | OUTPUT ] [READONLY]
] [ ,...n ]
[ WITH <procedure_option> [ ,...n ] ]
[ FOR REPLICATION ]
AS { [ BEGIN ] sql_statement [;] [ ...n ] [ END ] }
[;]
<procedure_option> ::=
[ ENCRYPTION ]
[ RECOMPILE ]
[ EXECUTE AS Clause ]
SQL Server CLR Stored Procedure Syntax:
ALTER { PROC | PROCEDURE } [schema_name.] procedure_name [ ; number ]
[ { #parameter [ type_schema_name. ] data_type }
[ = default ] [ OUT | OUTPUT ] [READONLY]
] [ ,...n ]
[ WITH EXECUTE AS Clause ]
AS { EXTERNAL NAME assembly_name.class_name.method_name }
[;]
Azure SQL Database Syntax:
ALTER { PROC | PROCEDURE } [schema_name.] procedure_name
[ { #parameter [type_schema_name. ] data_type }
[ VARYING ] [= default ] [ [ OUT [ PUT ]
] [,...n ]
[ WITH <procedure_option> [ , ...n ] ]
[ FOR REPLICATION ]
AS
{ <sql_statement> [...n ] }
[;]
<procedure_option> ::=
[ ENCRYPTION ]
[ RECOMPILE ]
[ EXECUTE_AS_Clause ]
<sql_statement> ::=
{ [ BEGIN ] statements [ END ] }
Note that in all 3 syntaxes above, sql_statement is one of the mandatory parts of the syntax. Parts inside [ and ] are optional, Read more about Transact-SQL Syntax Conventions here: https://msdn.microsoft.com/en-us/library/ms177563.aspx
As you see in the above syntaxes there is not any syntax like one you requested.

You cant add parameter with out altering stored proc. A closer option would be to use Default Parameters in case if you dont want to edit your stored procedure when you want to add new Parameter..
this goes something like this..
create proc usp_test
(
#param1 int=4,
#param2 int =null,
#param3 int =null
)
as
Begin
END
Those parameters with null wont be having any impact
