sql - 简单的sqlite查询，升序排列

Question

我正在使用QT并使用sqlite。当我写这个：

QSqlQuery q = db_.exec("SLECT *"
                       "From history;");

它按预期工作，但与此无关：

QSqlQuery q = db_.exec("SLECT *"
                       "From history"
                       "ORDER BY id ASC;");

这是表的创建：

db_.exec("CREATE TABLE IF NOT EXISTS history ("
          "id INTEGER PRIMARY KEY AUTOINCREMENT NOT NULL,"
          "url TEXT,"
          "day REAL,"
          "month REAL,"
          "year REAL,"
          "hour REAL,"
          "minute REAL,"
          "second REAL"
          ");");

谢谢

除了SELECT缺少E之外，您可能还需要*和From之间以及history和ORDER之间的空格字符-尝试：

QSqlQuery q = db_.exec("SELECT * "
                       "From history "
                       "ORDER BY id ASC;");
