Sama seperti FYI ....
select * from sys.types where system_type_id = 231 memberi Anda dua baris.
(Saya tidak yakin apa artinya ini tetapi saya 100% yakin itu mengacaukan kode saya sekarang)
sunting: saya kira artinya adalah Anda harus bergabung dengan user_type_id dalam situasi ini (situasi saya) atau mungkin juga user_type_id dan th esystem_type_id
name system_type_id user_type_id schema_id principal_id max_length precision scale collation_name is_nullable is_user_defined is_assembly_type default_object_id rule_object_id
nvarchar 231 231 4 NULL 8000 0 0 SQL_Latin1_General_CP1_CI_AS 1 0 0 0 0
sysname 231 256 4 NULL 256 0 0 SQL_Latin1_General_CP1_CI_AS 0 0 0 0 0
create procedure dbo.yyy_test (
@col_one nvarchar(max),
@col_two nvarchar(max) = 'default',
@col_three nvarchar(1),
@col_four nvarchar(1) = 'default',
@col_five nvarchar(128),
@col_six nvarchar(128) = 'default',
@col_seven sysname
)
as begin
select 1
end
Kueri ini:
select parm.name AS Parameter,
parm.max_length,
parm.parameter_id
from sys.procedures sp
join sys.parameters parm ON sp.object_id = parm.object_id
where sp.name = 'yyy_test'
order by parm.parameter_id
hasil:
parameter max_length parameter_id
@col_one -1 1
@col_two -1 2
@col_three 2 3
@col_four 2 4
@col_five 256 5
@col_six 256 6
@col_seven 256 7
dan ini:
select parm.name as parameter,
parm.max_length,
parm.parameter_id,
typ.name as data_type,
typ.system_type_id,
typ.user_type_id,
typ.collation_name,
typ.is_nullable
from sys.procedures sp
join sys.parameters parm ON sp.object_id = parm.object_id
join sys.types typ ON parm.system_type_id = typ.system_type_id
where sp.name = 'yyy_test'
order by parm.parameter_id
memberi Anda ini:
parameter max_length parameter_id data_type system_type_id user_type_id collation_name is_nullable
