SQL Server：在存儲過程中使用表或@table

我有一個存儲過程（見下文），它將數據插入物理表中，然後將信息與sys.databases連接起來。我在想，沒有用於數據插入的物理表格會更好嗎？在這個過程中將這些結果提取到表變量中會更好嗎？如果是這樣，該怎麼做？SQL Server：在存儲過程中使用表或@table

CREATE PROCEDURE dbo.PROC_getDbInfo 
AS 
    SET NOCOUNT ON 
    GO 
    TRUNCATE TABLE dbo.dbinfo 
    GO 
    EXECUTE sp_msforeachdb 'insert into dbo.dbinfo 
      select ''?'' as name, 
        type_desc, 
        physical_name, 
        state_desc, 
        size * 1.0/128 as size_in_mb, 
        max_size, 
        growth * 1.0/128 as growth_in_mb, 
        is_percent_growth, 
        is_read_only  
    from [?].sys.database_files' 

    GO 

    SELECT @@SERVERNAME as instance_name, 
     f.name, 
     d.create_date, 
     d.compatibility_level, 
     d.collation_name, 
     d.user_access_desc, 
     d.state_desc, 
     d.recovery_model_desc, 
     d.page_verify_option_desc, 
     d.log_reuse_wait_desc, 
     f.type_desc, 
     f.physical_name, 
     f.state_desc, 
     f.size_in_mb, 
     f.max_size, 
     f.growth_in_mb, 
     f.is_percent_growth, 
     f.is_read_only 
    FROM dbo.dbinfo AS f INNER JOIN 
      sys.databases AS d 
       ON f.name = d.name 
    ORDER BY f.name 
GO
