在T-SQL存储过程中，是否可以在输出参数之后添加可选参数？

Question

Let's say you have a T-SQL stored procedure with this signature:

myProcedure 
  @param1 varchar(10), 
  @param2 varchar(10) OUTPUT

Is it possible to add an optional parameter after the output parameter like this?

myProcedure
  @param1 varchar(10),
  @param2 varchar(10) OUTPUT, 
  @param3 varchar(10) = NULL

Answer 1

There is no need to ask a question like here because you can simply find it from internet or you can try it and find by creating a sample procedure

Any way the answer is yes you can

i have included a sample procedure for your reference

alter procedure proc1
@param1 nvarchar(10),
@param2  int output,
@param3 int=null

as 
begin 
select @param2
end
DECLARE @param2 int=10
EXEC proc1 @param1 = 'Calgary', @param2 = @param2 OUTPUT--will give result 10
EXEC proc1 @param1 = 'Calgary', @param2 = @param2 OUTPUT,@param3=100-- will give result 10
