【目標】實現表中多個字段模糊搜索。

【方法】ormlite like方法 ：like(columnName,pattern)? ? 使用%通配符來匹配，指定行數據，返回匹配到的結果

使用示范：mDao.queryBuilder().where().like("LastName", "A%").query(); 匹配A開頭的LastName

mDao.queryBuilder().where().like("LastName", “%s").query(); 匹配s結尾的LastName

mDao.queryBuilder().where().like("LastName", “%art%").query(); 匹配中間為art的LastName

對應SQL：SELECT * FROM `t_person` WHERE `LastName` LIKE 'A%'

【代碼】查詢與“孫”相關的數據。Dao cashDao=getCash();

//.or().like("month","%"+keys+"%").or().like("money","%"+keys+"%").or().like("payer","%"+keys+"%").or().like("way","%"+keys+"%")

List mdatas= cashDao.queryBuilder().where().like("client", "%"+keys+"%").or().like("month","'%"+keys+"%'").or().like("money","'%"+keys+"%'").or().like("payer","'%"+keys+"%'").or().like("way","%"+keys+"%").query();

for(Cashbook cashbook:mdatas){

String isIncome;

if(cashbook.getIncome()==0){

isIncome="支出";

}else{

isIncome="收入";

}

codeList.add(new TableCashData(cashbook.getPayer(),cashbook.getPayee(),cashbook.getClient(),cashbook.getMonth(),cashbook.getMoney(),cashbook.getWay(),cashbook.getRemark(),isIncome,cashbook.getDate(),false));

}

initColumn();

【報錯】“no such column ：孫”，把關鍵字認作“列名”了，不知為何！(應該不是這么拼的吧)10-07 16:28:37.812 27355-27355/menu.bottombar.bottombar E/SQLiteLog: (1) no such column: 孫

【解決辦法】

仔細觀察報錯語句：SELECT * FROM `tb_crashbook` WHERE ((((`client` LIKE '%孫%' OR `month` LIKE '%孫%' ) OR `money` LIKE '%孫%' ) OR `payer` LIKE ''%孫%'' ) OR `way` LIKE '%孫%' ) ，出現了兩個“ ?'?”符號，手動去掉語句首尾的即可，未弄清原因。List mdatas= cashDao.queryBuilder().where().like("client", "%"+keys+"%").or().like("month","'%"+keys+"%'").or().like("money","'%"+keys+"%'").or().like("payer","%"+keys+"%").query();
