我已经为连接三个表写了查询但是它出错了无法读取属性＆＃39;长度＆＃39;未定义的。
这是我的查询
var userquery = 'SELECT Device_Id,DATE_FORMAT(Date, "%d/%m/%Y") AS Date,Time,Session_Status,Associate_id,Patient_ID,Session_Id,Applicator_Type,Intensity,Motor_Frequency,CONCAT(PEMF_Min_Freq,"-",PEMF_Max_Freq)as PEMF,Waveform,Treatment_Duration, CONCAT(therapy_session_info.Patient_iid,"-",patient_info.first_name)as patient_info,patient_info.condition1, user_device_mapping.device_id from therapy_session_info INNER JOIN patient_info ON therapy_session_info.Patient_iid=patient_info.patient_id INNER JOIN user_device_mapping ON therapy_session_info.Device_Id=user_device_mapping.device_id where doctor_id=? and Date > DATE_SUB(NOW(), INTERVAL 2 DAY) ';
one: function (callback) {
db.query('SELECT doctor_id from user_info where email_id=?', [name], function (error, rows, fields, next) {
for (var i in rows) {
console.log('----------hhh--111-' + rows[i].doctor_id);
}
db.query(userquery,[rows[i].doctor_id], function (error, rows, fields, next) {
console.log('length--' + rows.length);
callback(error, rows);
console.log('report fetching error---'+rows);
});
});
}
这是therapy_session_info表
