// 用gorm实现分页查询db.Order("id desc").Limit(10).Offset(1).Find(&List).Count(&totalRows)//以上查询是没有任何问题的,正常结果//但是当查询第2页每页查询10条时,如以下语句,这时totalRows为0,且报错 sql: no rows in result setdb.Order("id desc").Limit(10).Offset(10).Find(&List).Coun...
要点是,count的查询必须写在分页之前,可以写在其余查询逻辑之后。 如果写在分页之后,第一页不会报错,但是从第二页开始就会报错sql: no rows in result set 如果count写的太靠前了,就没办法顾及到其他必要的查询条件。
