Question

我在SQL Server数据库中有一个查询，它获取存储过程参数，如下所示：

SELECT
    parameter.name, 
    types.name,
    types.is_nullable
FROM 
    sys.parameters AS parameter 
INNER JOIN 
    sys.procedures AS procedures ON parameter.object_id = procedures.object_id 
INNER JOIN 
    sys.types AS types ON parameter.system_type_id = types.system_type_id 
                       AND parameter.user_type_id = types.user_type_id
WHERE 
    procedures.name = 'UsernameSP'

返回结果集：

name           name        is_nullable
--------------------------------------
@Username      nvarchar    1
@CreateDate    datetime    1

我需要查询Oracle数据库。如何在Oracle中运行此查询？

Answer 1

select argument_name,position, data_type
from user_arguments
where object_name =  <your procedure>
order by position

假设您已登录到过程所在的当前架构。我认为oracle没有相当于“is_nullable”
