Question

如何使用SQL Server 2005中的元数据获取存储过程的输入参数列表？我想对它进行SELECt，然后迭代变量名。

Answer 1

从这里开始

select * from information_schema.PARAMETERS
where SPECIFIC_NAME = 'YourStoredProcedureName'
order by ORDINAL_POSITION

查找parameter_name，data_type，parameter_mode

Answer 2

SQL-Server本地方式：

select      type_name(system_type_id) as type_name
              , parameter_id
              , name
              , max_length
from          sys.parameters
where        object_id = object_id(N'{schema}.{name}');

踢屁股!!!!!

我用它来为经典的asp苦差事生成ADO参数。你救了我几个小时!! 将PROCEDURE dbo.createParms @procname VARCHAR（200）改为

SELECT 'dbCommand.Parameters.Append (dbCommand.CreateParameter("'+ parameter_name + '"' + 
    ',' 
    + CASE WHEN data_type='char' THEN 'adChar'
    WHEN data_type='varchar' THEN 'adVarChar'
    WHEN data_type='int' THEN 'adInteger'
    WHEN data_type='text' THEN 'adLongVarchar'
    WHEN data_type='datetime' THEN 'adDBTimeStamp'
    WHEN data_type='bit' THEN 'adBoolean'
    WHEN data_type='uniqueidentifier' THEN 'adGuid'
    end
    +',adParamInput,'
    +CASE WHEN data_type='int' THEN '0' 
        WHEN  data_type='datetime' THEN '0'
        WHEN data_type='varchar' THEN CONVERT(VARCHAR,character_maximum_length)
        WHEN data_type='char' THEN CONVERT(VARCHAR,character_maximum_length)
        WHEN data_type='text' THEN 'len('+replace(parameter_name,'@','')+')'
        WHEN data_type='bit' THEN '0'
        WHEN data_type='uniqueidentifier' THEN '0'
     end
    + ','+replace(parameter_name,'@','') +'))' AS parm
from information_schema.PARAMETERS
where SPECIFIC_NAME = @procname
