获取SP和函数的所有输入和输出参数集有更简单、更正确的方法，请尝试以下语句。 （来源为）

选择SCHEMA\u NAME（SCHEMA\u ID）作为[SCHEMA]，
SO.Name作为[ObjectName]，
SO.Type_Desc AS[对象类型（UDF/SP）]，
PM.Parameter_ID为[ParameterID]，
案例
当pm.system\u type\u id=pm.user\u type\u id时，则为“system\u type”
else“用户类型”
结束为[TypeDescr]，
案例
当PM.Parameter_ID=0时，则“返回”
我叫什么名字
结束为[ParameterName]，
“['+TYPE_NAME（PM.User_TYPE_ID）+']”作为[ParameterDataType]，
案例
当在（'float'，'uniqueidentifier'，'datetime'，'bit'，'bigint'，'int'，'image'，'money'，'xml'，'varbinary'，'tinyint'，'text'，'ntext'，'smallint'，'smallmoney'）中键入\u NAME（PM.User\u TYPE \u ID）时，则
当在（'decimal'，'numeric'）中键入_NAME（PM.User_TYPE_ID）时，则“（'+CAST（精度为VARCHAR（4））+”，'+CAST（比例为VARCHAR（4））+”）”
其他的
案例
当PM.Max_Length为-1时，则“（'+CAST（PM.Max_Length为VARCHAR（4））+”）”
当（TYPE_NAME（PM.User_TYPE_ID）=“xml”）或（PM.system_TYPE_ID PM.User_TYPE_ID）时，则“”
else'（最大值）'
结束
结束为[大小]，
案例
当PM.Is_Output=1时，则为“Output”
其他“输入”
结束为[方向]
从sys.objects开始
内部连接sys.parameters作为SO.OBJECT\u ID=PM.OBJECT\u ID上的PM
其中输入（'P'，'FN'）
ORDER BY[Schema]，SO.Name，PM.parameter\u id

请按照此链接中的建议尝试sp_procedure_params_行集-感谢您的快速响应。毫无疑问，sp_procedure_params_行集“TestDefaultSpValue_Default”sp_procedure_params_行集“TestDefaultSpValue_NoDefault”返回相同的列和值。如此链接中所述，SQL Server仅维护CLR对象的默认值在此目录视图中；因此，对于Transact-SQL对象，此列的值为0。若要查看Transact-SQL对象中参数的默认值，请查询sys.SQL_modules目录视图的definition列，或使用object_definition system函数。我认为除了解析definition列之外，没有其他方法。请投票赞成更改e here:失败，因为您可以使用与以前一样的数据类型定义。您应该尝试：选择*from information_schema.information_schema.PARAMETERS，其中specific_name='my_sp_name'**您需要将MyProcName更改为proc的名称或通配符）**这将获得默认值，如果您喜欢CTE，则更容易理解（通用表表达式）
