php and postgres quessie.....

i have an sql command like...

select account.* billing.* orders.* from account, billing, orders WHERE.....

and I am putting the results of this query into a serialized php array... like so.....

 for($i=0; $row = @pg_fetch_array($res,$i); $i++)
    {
        $tabledata = $row;
    }

however, i am getting undesired results because the tables have common column names, for example, accounts.id order.id and billing.id and yet my $tabledata variable just has the on $tabledata["id"] element...

what i need (and i am not sure if its at a php level or sql level) is something which will allow me to have an array indexed by tablename.columnname rather than just column name...

so for the above example i would have

$tabledata['accounts.id'] == //the id var from the account table
$tabledata['billing.id'] == // the id var from the billing table
$tabledata['orders.id'] == // the id var from the orders table

instead of just the one $tabledata['id'] value from who knows what table...

can anyone help!!??

In that case you should go for pg_fetch_row.

$result = pg_Exec($conn,"select account.*,billing.*,order.* from ....");

$num = pg_numrows($result);

for ($i=0; $i < $num; $i++)
{
  $r = pg_fetch_row($result, $i);

  for ($j=0; $j < count($r); $j++) {
    echo "$r[$j]&nbsp;";
}

// the fields would be in the same order as in table and between tables it would be in same order as you have wrote table names.

What type of database are you using, MySQL, MSSQL, Oracle, ...?

I think the ideal solution would be to alias each of the fields, but it depends how the dynamic SQL is being built.  Can you give more details of this part of the code?

Generally speaking, unless you actually alias the fields in some way then the first "id" field will be "id" the next one "id_1" and so on.

If you can get you sql to look more like...

select
  account.id 'account.id',
  account.name 'account.name',
  billing.id 'billing.id',
  billing.address 'billing.address',
  orders.id 'orders.id'
  ...
from
  account, billing, orders
where.....

... then your problems will be solved.

Depending on your database being used, you can probably extract the necessary field names to build the SQL like this.
