我有一個SQL Server數據庫的查詢獲取存儲這樣的程序參數:獲得Oracle存儲過程的參數
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'
這將返回一個結果集:
name name is_nullable
--------------------------------------
@Username nvarchar 1
@CreateDate datetime 1
我需要這個查詢一個Oracle數據庫。我如何在Oracle中運行此查詢?
