public void search()
{
rpl='select name,industry,type,AccountNumber,phone,AnnualRevenue from account';
if((aname!=''&&aname!=null)&&(atype!=''&&atype!=null)&&(aindustry!=''&&aindustry!=null))
{
rpl=rpl+' where (industry=:aindustry AND type=:atype AND name=:aname)';
}
else
{
if((aname!=''&&aname!=null)&&(atype!=''&&atype!=null))
{
rpl=rpl+' where (type=:atype AND name=:aname)';
}
