我有以下代碼，使用pscyopg2：sql = 'select %s from %s where utctime > %s and utctime < %s order by utctime asc;'data = (dataItems, voyage, dateRangeLower, dateRangeUpper)rows = cur.mogrify(sql, data)輸出：select 'waterTemp, airTemp, utctime' from 'ss2012_t02' where utctime > '2012-05-03T17:01:35+00:00'::timestamptz and utctime < '2012-05-01T17:01:35+00:00'::timestamptz order by utctime asc;當(dāng)我執(zhí)行此操作時(shí)，它會(huì)崩潰-這是可以理解的，因?yàn)楸砻車囊?hào)是非法的。有沒(méi)有一種方法可以合法地將表名作為參數(shù)傳遞，或者我是否需要進(jìn)行（明確警告）字符串連接，即：voyage = 'ss2012_t02'sql = 'select %s from ' + voyage + ' where utctime > %s and utctime < %s order by utctime asc;'為任何見(jiàn)識(shí)加油。
