Déterminer par programme combien de paramètres dans une procédure stockée

Question

Y at-il quelque chose dans les vues de catalogue dans SQL Server qui vous donnera une liste des procédures stockées comme select name from sys.procedures qui vous indiquera également combien de paramètres chaque procédure prend? Intellisense vous apportera les noms des paramètres et Visual Studio le sait également. Yat-il un meilleur moyen d'obtenir un résultat de procédures stockées et le nombre (et/ou le nom) des paramètres que chaque procédure prend?

Je suppose que l'on pourrait faire cela est ils sont analysés sp_helptext 'sprocName' mais je pense qu'il y a une meilleure façon de le faire.

Creusez un peu plus creuser et est venu avec

;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 faire le travail.

Answer 1

Vous pouvez obtenir à l'information des paramètres comme ceci:

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); 

Answer 2

Essayez celui-ci sur:

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

Answer 3

Si, comme vous l'avez mentionné, vous utilisez un langage .NET pour cela, vous pouvez utiliser la méthode DeriveParameters de SqlCommandBuilder. De cette façon, vous n'avez pas besoin d'écrire quoi que ce soit dans le backend et faites cela uniquement dans le code .NET.
