我在模型中使用@CreateDateColumn()。使用查询生成器进行选择时，如何格式化选择内容中的日期？

  @CreateDateColumn()
  createdAt: Date;

    const documentarys = await getManager()
      .getRepository(IncomingDocumentary)
      .createQueryBuilder('d')
      .leftJoinAndSelect('d.tireBrand', 't')
      .select([
        'd.code as code',
        'd.tireSize as tireSize',
        'd.applicableCarModel as applicableCarModel',
        'd.amount as amount',
        'd.price as price',
        'd.createdAt as createTime',
        't.name as tireBrandName',
      ])
      .getRawMany();

使用javascript选择格式后，您可以更轻松地对其进行格式设置，但是，如果您确实要在select查询中对其进行格式设置，则应该使用数据库功能。例如，如果您有基于sql的数据库，则可以这样设置其格式：

const documentarys = await getManager()
  .getRepository(IncomingDocumentary)
  .createQueryBuilder('d')
  .leftJoinAndSelect('d.tireBrand', 't')
  .select([
    'd.code as code',
    'd.tireSize as tireSize',
    'd.applicableCarModel as applicableCarModel',
    'd.amount as amount',
    'd.price as price',
    'TO_CHAR(d.createdAt::DATE, 'dd/mm/yyyy')as createTime',
    't.name as tireBrandName',
  ])
  .getRawMany();

使用typeORM Select Query Builder时如何格式化日期？
