pdo - mysql join two tables select and records problems -

-

i want show below info onto webpage :
date - personal expense (business expense)
06-june-2012 - usd555.00 (usd3022.00)
05-june-2012 - usd666.00 (usd0.00)
04-june-2012 - usd0.00 (usd444.40)
04-june-2012 - usd333.00 (usd2333.40)

currently code :

$sql = "select payment_date, sum(price) expense category=? spender_id=? group payment_date";     $q = $conn->prepare($sql);     $result = $q->execute(array("personal", $user_id));     while($r = $q->fetch(pdo::fetch_assoc)){         $payment_date_db = $r['payment_date'];         $payment_date_db2 = date("d-f-y", strtotime($payment_date_db));         $price_db = $r['sum(price)'];          echo $payment_date_db2 . " - " . $money_currency . $price_db . "<br />";     }

i don't know how select , display business expense record , show blanket sign (). idea?

you should provide more details in regards table schema, think can infer query it's this:

expense(payment_id [pk], spender_id [fk], category [fk??], price, payment_date)

where category field contains either "personal" or "expense".

so if want sum of both personal , business expense particular spender each date, try query:

select      payment_date,     sum(if(category = 'personal', price, 0)) personal_expense_total,     sum(if(category = 'business', price, 0)) business_expense_total      expense      spender_id = ? group      payment_date

so in php code, can this:

$sql = '     select         payment_date,         sum(if(category = "personal", price, 0)) personal_expense_total,         sum(if(category = "business", price, 0)) business_expense_total     expense     spender_id = :spender_id     group payment_date'; $stmt = $conn->prepare($sql); $stmt->bindparam(':spender_id', $user_id, pdo::param_int); // assuming $user_id contains integer $stmt->execute();  while($r = $stmt->fetch(pdo::fetch_assoc)) {     $date = date('d-f-y', strtotime($r['payment_date']));     $personal = 'usd' . number_format($r['personal_expense_total'], 2);     $business = 'usd' . number_format($r['business_expense_total'], 2);      echo "$date - $personal - ($business)<br />"; }

on website user have 1 group. , user can change group. it's made user.groups.clear() and user.groups.add(new_group) but it's not efficient, because there 2 sql query: delete, insert. how can change group update query? user , group related each other using manytomanyfield . means intersection table exists relating both entities, , if don't specify model map (using through attribute) django creates 1 you. looking @ sources django.contrib.auth.models see that's case. fortunatly, can access intermediary model using through attribute of manager (in case, user.groups.through ). can use regular model. example: >>> alice = user.objects.create_user('alice', 'alice@example.com', 'alicepw') >>> employee = group.objects.create(name='employee') >>> manager = group.objects.create(name='manager') >>> alice.groups.add(employee) >>> alice.groups.all() [<group: employee...
