创建存储过程如下:

procedure bookproc
@id
int, @title char(20) output
As
Select
@title=title from book where id=@id
执行该存储过程的方法正确的是()。
A: exec bookproc 1, @title output
print
@title
B: exec bookproc @id=1, @title output
print
@title
C: declare @title char(20)
exec
bookproc 1, @title output
print
@title
D: declare @title char(20)
exec
bookproc @id=1, @title output
print
@title
Create
procedure bookproc
@id
int, @title char(20) output
As
Select
@title=title from book where id=@id
执行该存储过程的方法正确的是()。
A: exec bookproc 1, @title output
@title
B: exec bookproc @id=1, @title output
@title
C: declare @title char(20)
exec
bookproc 1, @title output
@title
D: declare @title char(20)
exec
bookproc @id=1, @title output
@title
