idea is to put the values of column name from first table in the second table where sID is the same

i tried Select * From TABLE1 c LEFT join TABLE2 T on c.sID=T.sID

Answer 1

Your left join is the wrong way around.

 select table2.sid, pname, table1.name as supplier 
 from table2  
    left join table1 on table2.sid = table1.sid 

or change your left join to a right join
