如何在SQL Server中获取有关函数特殊参数的所有信息？

Question

我需要知道如何获取SQL Server中所有函数参数的所有信息的特殊名称，类型，顺序和IsOutput？

例如：

ufnGetContactInformation() in AdventureWorks2014

ParameterName   Type    Order
@PersonID       int     1     

Answer 1

我认为应该这样做：

USE AdventureWorks2012;

SELECT  o.name AS [Function Name]
       ,p.is_output
       ,p.name AS [Parameter Name]
       ,p.parameter_id AS [Parameter Number]
       ,t.name AS [Parameter Type]
FROM    sys.objects o
        INNER JOIN sys.parameters p ON o.object_id = p.object_id
        INNER JOIN sys.types t ON p.system_type_id = t.system_type_id
WHERE   o.type = 'FN'
ORDER BY o.name
       ,p.parameter_id;
