我直接贴代码了，做一个备份

  public async zbjhList(request: Hapi.Request, h: Hapi.ResponseToolkit) {
    const { page, size } = request.payload;
    const min = (page - 1) * size;
    const max = page * size;
    let sql = `SELECT * FROM (SELECT ROWNUM AS rowno, t.* FROM  "bsjduser".jcsj_zbjh t WHERE  ROWNUM <= ${max}) table_alias
 WHERE table_alias.rowno >= ${min}`
    const binds = {};
    const options = {
      outFormat: oracledb.OUT_FORMAT_OBJECT
    };
    let result = null;
    result = await h.oracle.execute(sql, binds, options).catch(err => {
      console.log(err)
    });
    const data = result.rows;
    sql = `select count(*) as count from "bsjduser".jcsj_zbjh`;
    result = await h.oracle.execute(sql, binds, options).catch(err => {
      console.log(err)
    });
    result = await h.oracle.execute(sql, binds, options).catch(err => {
      console.log(err)
    });
    const total = result.rows[0]['COUNT'];
    return {
      code: 1,
      msg: '值班计划列表获取成功',
      data: data
      paginate: { size: parseInt(size), page: parseInt(page), pages: parseInt(total / size), total: total }
    }
  }
