編程方式確定有多少參數在存儲過程中

有沒有在SQL Server目錄視圖，這將使你像select name from sys.procedures的存儲過程，也將告訴你每道工序多少參數接受一個列表什麼？ Intellisense會帶你參數的名稱，Visual Studio也會知道。有沒有更好的方法來獲取存儲過程的結果以及每個過程所需參數的數量（和/或名稱）？編程方式確定有多少參數在存儲過程中

我想一個能做到這一點是他們解析sp_helptext的「sprocName」，但我認爲有一個更好的辦法做到這一點。

挖多一點挖想出了

;with x 
as 
(
SELECT 
    p.name AS Parameter,   
    t.name AS [Type], 
    sp.name 
FROM sys.procedures sp 
JOIN sys.parameters p 
    ON sp.object_id = p.object_id 
JOIN sys.types t 
    ON p.system_type_id = t.system_type_id 
) 
select name,Parameter,COUNT(*) 
from x 
group by name,Parameter

which'll做的工作。

您是否試圖從.NET語言（您提到Visual Studio）或直接在TSQL內部執行此操作？ –

@YuriyGalanter在Visual Studio裏面怎麼樣，因爲我發現了一個TSQL soltuion（並且你不能只是製作一個上面TSQL的存儲過程:)） – wootscootinboogie

還有一個更好的方法，請看下面的答案 –

您可以在參數信息得到像這樣：

declare @ProcedureName sysname; 
set @ProcedureName = '[dbo].[YourProcedureName]'; 

select sp.name, 
     spa.name, 
     spa.is_output 
from sys.procedures sp 
join sys.parameters spa on 
     sp.object_id = spa.object_id 
where sp.object_id = object_id(@ProcedureName);

只是好奇，你爲什麼創建該變量，而不是隻是使Where子句，其中'sp.name ='x'' – wootscootinboogie

只是習慣，我想，如果你會從DAL調用等。使用'object_id'允許你傳遞一個DatabaseId作爲以及名稱解析的架構。 –

啊，整齊。我必須在我的工具箱中將其存檔。 – wootscootinboogie

試試這個：

select * from information_schema.parameters 
where specific_name='your_procedure_name'

如果真如你所說，你使用.NET語言爲此，您可以使用SqlCommandBuilder的DeriveParameters方法。這樣你就不必在後端編寫任何東西，只需在.NET代碼中完成。

.NET新手，並沒有聽說過這個，謝謝。 – wootscootinboogie

還有一些有趣的程序，由微軟提供。您可以從中選擇正確的數據。另請參見System Stored Procedures
