QT requested database does not belong to the calling thread.线程中查询数据报错
QString name = "ttx";
QSqlQueryModel* sql_model;
QString sql_comm = QString("select * from dssb_moddve_loddt_tab where name='%1'").arg(name);
sql_model->setQuery(sql_comm);//错误
sql_model->setQuery(sql_comm, db);//正确，指定数据库连接
sql_model数据放入tableView控件
m_sqlDataBase是连接数据库的名字
QSqlDatabase m_sqlDataBase;

QSqlQuery query(sql, m_sqlDataBase); //创建query时，指定数据库连接
if(!query.exec()){
qWarning()<<"query error,"<<m_sqlDataBase.lastError();
