In my application i have three tables, reservation, patient and sub_unit, i need to take the patient_id from reservation table and query the patient table for patient data,same time i need to take the sub_unit_id from the reservation table and query the sub_unit name from the sub_unit table… i need to put all this data in to an one array in the sequence like
patient_id, sub_unit_name, patient_name, address and pass it to the Codeigniter table class to draw a table.

How can I query three tables in the same time to query out this data? can you guys help me out?

Answer 1

Select r.patient_id, s.sub_unit_name, p.patient_name, p.address 
from reservation r, sub_unit s, patient p 
where r.patient_id = p.patient_id and r.sub_unit_id = s.sub_unit_id
