Xutils操作数据库

Posted 2021-08-28 木白星枝

1.查询数据库

 List<androidSynchronizationModel> m1 = null;
        ProjectTableDAO a=new ProjectTableDAO();
        long p1=a.findProjectTable();
        try {
            m1= GISApplication.db
                    .selector(AndroidSynchronizationModel.class)
                    .where("project_id","=",p1)
                    .and("table_name","=",tableName)
                    .findAll();
        } catch (DbException e) {
            e.printStackTrace();
        }

2.新建

 ProjectTableDAO a=new ProjectTableDAO();
            long p1=a.findProjectTable();
            androidSynchronizationModel=new AndroidSynchronizationModel(p1,tableName,"T");
            try {
                GISApplication.db.saveOrUpdate(androidSynchronizationModel);
            } catch (DbException e) {
                e.printStackTrace();
            }

3.修改

 androidSynchronizationModel.upload_tag="F";
            try {
                GISApplication.db.update(androidSynchronizationModel,"upload_tag");
            } catch (DbException e) {
                e.printStackTrace();
            }
