tdengine用的是2.4.0.16，driver-go版本用的是v2.0.4
示例代码：
// 获取状态规则列表
func (t *Tdengine) GetStateRuleList(where map[string]string) ([]*StateRuleTdObj, error) {
whereStr := t.setwhere(where)

}
filedSet := t.setfield(fields)
stable := enum.TDENGINE_STATUS_RULE_STABLE_NAME
rowsData := make([]StateRuleTdObj, 0)
query := fmt.Sprintf("select %s from %s %s order by ts desc", filedSet, t.DbName+"."+stable, whereStr)
logx.Info("查询语句:", query)
conn, err := t.ConnNew()
if err != nil {
return nil, err
}
defer conn.Close()
// conn := SRConn
// count
// countQuery := fmt.Sprintf("select count() as count from %s %s", t.DbName+"."+stable, whereStr)
// logx.Info("countQuery：", countQuery)
// rowsCount := conn.QueryRow(countQuery)
// logx.Errorf("%v",rowsCount.Err())
// var count int64
// if err := rowsCount.Scan(&count); err != nil {
// logx.Error("count赋值err：", err)
// return nil, err
// }

// }
// end count
rows, err := conn.Query(query)
if err != nil {
return nil, err
}
for rows.Next() {
var r StateRuleTdObj
if err := rows.Scan(&r.StateRuleModelsId, &r.StateRulePartnerId, &r.StateRuleEquipmentId, &r.ClassifyId, &r.CateId, &r.LevelId, &r.ParamId, &r.Param, &r.Pid, &r.RuleStandardType, &r.Point, &r.PointName, &r.PointUnitId, &r.PointUnitName, &r.ProductId, &r.StateRuleDeviceId, &r.EquipmentId, &r.DeviceId, &r.ClassifyTypeId, &r.ClassifyTypeDefaultClassifyId, &r.CompanyId, &r.CompanyIndexId, &r.StateRuleId); err != nil {

return nil, err
}
rowsData = append(rowsData, &r)
}
return rowsData, nil
}
func (t *Tdengine) GetModelsTheoryList(equipmentId int64) ([]*ModuleTheoryTdObj, error) {
fields := []string{
"equipment_id", "name", "device_id", "product_id", "model_value", "gid", "threshold_type", "threshold", "models_param_id", "standard_type", "standard", "point", "param_type", "point_name", "point_unit_name", "theory_id",
}
filedSet := t.setfield(fields)

query := fmt.Sprintf("select %s from %s where equipment_id=%d order by ts desc", filedSet, t.DbName+"."+stable, equipmentId)
logx.Info("查询语句:", query)

}
return rowsData, nil
}
请问每次查询会返回多少条数据
每次返回的数据量不多，有的多有的少，20-30条吧，当没有查询到记录也会出现这种情况
您可以升级 TDengnie 到3.0.2.5，driver-go 到 3.1.0 再试一下
