我正在嘗試對(duì)序列化列進(jìn)行簡(jiǎn)單查詢，您該怎么做？serialize :mycode, Array1.9.3p125 :026 > MyModel.find(104).mycode MyModel Load (0.6ms) SELECT `mymodels`.* FROM `mymodels` WHERE `mymodels`.`id` = 104 LIMIT 1 => [43565, 43402] 1.9.3p125 :027 > MyModel.find_all_by_mycode("[43402]") MyModel Load (0.7ms) SELECT `mymodels`.* FROM `mymodels` WHERE `mymodels`.`mycode` = '[43402]' => [] 1.9.3p125 :028 > MyModel.find_all_by_mycode(43402) MyModel Load (1.2ms) SELECT `mymodels`.* FROM `mymodels` WHERE `mymodels`.`mycode` = 43402 => [] 1.9.3p125 :029 > MyModel.find_all_by_mycode([43565, 43402]) MyModel Load (1.1ms) SELECT `mymodels`.* FROM `mymodels` WHERE `mymodels`.`mycode` IN (43565, 43402) => []
