I have tried your solution but another error apears...
Column 'cpu.name' is invalid in the select list because it is not contained in either an aggregate function or the GROUP BY clause

ok ,well this is your next problem. check this:"SELECT cpu.name,image1,Min(cost),MAX(cost) FROM sell,cpu WHERE cpu.name=sell.brand group by(cpu.name)"

Try this:

C#

SqlCommand cmd = new SqlCommand("SELECT cpu.name,image1,Min(cost),MAX(cost) FROM sell,cpu WHERE cpu.name=sell.brand group by(cpu.name)", con);
