Good Night I am seeking some help with a sql question. The question is: For both Electrical and Mechanical components list the total number under each category and the total number of suppliers that supply those components under each category. Note# A component can have a maximum of three levels of subcomponents. I tried using a nested IF statement and also and Inner Join but neither of them is working...I am a bit lost and confused and how to go next. Codes I tried:SELECT SupID, (SELECT COUNT(e.PartNo) AS myTotalElec, COUNT(s.SupID) AS myTotalElecSupplierFROM ElecComponent AS e, Supplier AS sWHERE s.PartNo=e.PartNo), (SELECT COUNT(m.PartNo) AS myTotalMech, COUNT(s.SupID) AS myTotalMechSupplierFROM MechComponent AS m, Supplier AS sWHERE s.PartNo=m.PartNo)FROM Supplier AS sORDER BY SupID; SELECT Supplier.SupName, ElecComponent.PartNo, MechComponent.PartNoFROM ElecComponent, MechComponentINNER JOIN SupplierON Supplier.SupID=ElecComponent.PartNoORDER BY SupName; Could someone assist me?
