Question

我有这些查询

    QSqlQuery query;
  query.exec("Create table users (name varchar(20), type int)");
  query.exec("INSERT INTO users values('Daihee',0)");
  query.exec("INSERT INTO users values('Jessica',1)");
  query.exec("INSERT INTO users values('Tony',1)");
  query.exec("INSERT INTO users values('Yacine',0)");
  //PROJECTS
  query.exec("Create table projects (name varchar(20),owner varchar(20) ,teamSize int)");
  query.exec("INSERT INTO projects values('P1','Daihee', 5)");
  query.exec("INSERT INTO projects values('P2','Daihee', 5)");
  query.exec("INSERT INTO projects values('P3','Daihee', 5)");

  query.exec("Create table projectStu (projectName varchar(30), stuName varchar(30)");
  query.exec("INSERT INTO projectStu values('P1','Jessica')");
  query.exec("INSERT INTO projectStu values('P2','Jessica')");

但是第三个表没有被创建，我也在使用SQLITE 任何提示都可能有所帮助！

Answer 1

您在第三个表格定义的末尾错过了结束语)。

另请查看exec()的返回值以查看是否出现问题，并lastError()了解它是什么。

第3桌不会创建
