如何探險臨時表中的內容時，程序調試

Question

當我使用SQL Server 2008這樣的說法：

--INSERT INTO #tmp_file EXEC ('restore_database_proc N''' + @database_bak_path + '''') 
    INSERT INTO #tmp_file EXEC ('RESTORE FILELISTONLY FROM DISK = N''' + @database_bak_path + '''') 
    set @database_mdf_oldname = (select LogicalName from #tmp_file where Type = 'D') 
    set @database_log_oldname = (select LogicalName from #tmp_file where Type = 'L') 

的varible @database_mdf_oldname和@database_log_oldname有當我調試的程序沒有價值，所以我要檢查臨時表有價值，爲什麼結果沒有給變量？

您可以添加一個select語句select * from #tmp_file和SQL服務器它可以顯示臨時表導致這樣的：

INSERT INTO #tmp_file EXEC ('RESTORE FILELISTONLY FROM DISK = N''' + @database_bak_path + '''') 
    select * from #tmp_file--this can be diaplay on debugging result 
    set @database_mdf_oldname = (select LogicalName from #tmp_file where Type = 'D') 
    set @database_log_oldname = (select LogicalName from #tmp_file where Type = 'L')
