Question

我开发了typeorm querybuilder。为了进行调试，我想显示sql。

我测试了printSql()方法。但没有显示任何SQL。

      const Result = await this.attendanceRepository
      .createQueryBuilder("attendance")
      .innerJoin("attendance.child", "child")
      .select(["attendance.childId","child.class","CONCAT(child.firstName, child.lastName)"])
      .where("attendance.id= :id", { id: id})
      .printSql()
      .getOne()
      console.log(Result);

它返回了。

Attendance { childId: 4, child: Child { class: 'S' } }

我想要的结果是获得SQL

有什么不对的地方吗？有什么好的方法来获取sql吗？

如果有人有意见，请告诉我。

谢谢

.getQuery()或.getSql()

const sql1 = await this.attendanceRepository
      .createQueryBuilder("attendance")
      .innerJoin("attendance.child", "child")
      .select(["attendance.childId","child.class","CONCAT(child.firstName, child.lastName)"])
      .where("attendance.id= :id", { id: id})
      .getQuery();
      console.log(sql1);

const sql2 = await this.attendanceRepository
      .createQueryBuilder("attendance")
      .innerJoin("attendance.child", "child")
      .select(["attendance.childId","child.class","CONCAT(child.firstName, child.lastName)"])
      .where("attendance.id= :id", { id: id})
      .getSql();
      console.log(sql2);
