開發輔助工具，有時一段文本如D1,D2,D3,...,D10很不想自己打字，很想從哪復制過來用，這工具就可以派得上了。也可以創建一個更復雜的如這樣ISNULL([D1],0) AS [D1],ISNULL([D2],0) AS [D2],ISNULL([D3],0) AS [D3],ISNULL([D4],0) AS [D4],ISNULL([D5],0) AS [D5],ISNULL([D6],0) AS [D6],ISNULL([D7],0) AS [D7],ISNULL([D8],0) AS [D8],ISNULL([D9],0) AS [D9],ISNULL([D10],0) AS [D10]，要自己輸入感覺就不好受，該工具就可以代勞了放心
