I need to join 3 tables and show all the data :
The following query works fine. Here i have joined 2 tables called "comparitive_statement1" and "comparitive_st_sup". Here the total everything is fine.
SELECT tc.*,sum(tci.total_inr) as tot1, tci.supplier_name,tci.currency as currency2 FROM comparitive_statement1 tc INNER JOIN comparitive_st_sup tci ON tc.tender_id=tci.tender_id WHERE tc.tender_id='$tender_id' and tc.sup_name=tci.supplier_name GROUP BY tc.sup_name ORDER BY tc.sup_name ASC
Now i need to join one more table called "comparitive_st_tech_compliance" with same tender_id and supplier_name. Here when i join my totals are wrong. Placing the query which i have done:
SELECT tc.*, sum(tci.total_inr) as tot1, tci.supplier_name,tci.currency as currency2 FROM comparitive_statement1 tc INNER JOIN comparitive_st_sup tci ON tc.tender_id=tci.tender_id INNER JOIN comparitive_st_tech_compliance cl ON tci.tender_id=cl.tender_id and tc.sup_name=cl.supplier_name WHERE tc.tender_id='$tender_id' GROUP BY tc.sup_name,cl.supplier_name ORDER BY tc.sup_name ASC
What iam doing wrong?

part
try
INNER JOIN comparitive_st_tech_compliance cl ON
tci.tender_id=cl.tender_id and tc1.supplier_name=cl.supplier_name
