$connstr = "driver=microsoft access driver (*.mdb);dbq=".realpath("db.mdb");????
$connid = odbc_connect($connstr,"",sql_cur_use_odbc);
$odbc_exec = odbc_exec($connid,"insert into tablename (name) values('name')");????
$query = odbc_do($connid,"select * from tablename ");???
$odbc_result_all = odbc_result_all($query);????
echo $odbc_result_all;?
//保存数据
$connstr = "driver=microsoft access driver (*.mdb);dbq=".realpath("db.mdb");?
$connid = odbc_connect($connstr,"insert into t……")
//查询数据
$a = 0;
$begintime = time();
while($a<100)
{
??? $conn = odbc_connect("forphp","sa","sa");
