MySQL - How to select Multiple rows from Multiple tables -


i have question sql statement, reason script not working properly.. scenario; have 6 tables

patient -patientid -patientname -employerid fk employer.employerid.  employer -employerid -employername  carrier -carrierid -carriername  appointment -appointmentid -aptdatetime -patientid fk patient.patientid  insuranceplan -planid -groupname -employerid fk employer.employerid -carrierid fk carrier.carrierid  inssub -insubid -dateeffective -planid fk insplan.planid -suscriber fk patient.patientid

my script: need rows 5 tables,, not sql indexes validation, that's why script not working !

select p.patientname, e.employername, c.carriername, ip.groupname, a.aptdatetime, i.dateeffective  patient p, employer e, inssub i, insuranceplan ip, carrier c, appointment  e.employernum = p.employernum ,        i.subscriber = p.patientid ,       i.planid = ip.planid ,       ip.carrierid = c.carrierid ,       ip.employerid = e.employerid ,       ip.planid = i.planid ,           a.patientid = p.patientid ,           a.datetstamp > '2013/01/01' ,           a.aptdatetime != '0001-01-01 00:00:00'

it simpler if use explicit joins rather comma-delimited tables:

select p.patientname, e.employername, c.carriername, ip.groupname, a.aptdatetime, i.dateeffective patient p join employer e on p.employerid = e.employerid join insuranceplan ip on e.employerid = ip.employerid join carrier c on ip.carrierid = c.carrierid join appointment on p.patientid = a.patientid join inssub on p.patientid = i.subscriber , ip.planid = i.planid a.datetstamp > '2013/01/01'   , a.aptdatetime != '0001-01-01 00:00:00'
