我尝试在编写SQL时更好，并希望将以下3个SQL查询/代码组合到一个SQL调用中 - 是否可能？ （我意识到它不会格式化为100％，因为我特别指出monthly_totals，但如果那也可能......？）
注意：下面提供的代码可以让您了解我的数据库结构以及我想要完成的任务。
$ret = array(
'raw' => array(),
'total' => '0.00',
'monthly_totals' => array()
);
if (!empty($sales_rep_id)) {
$orders = $this->query("
SELECT
id,
invoice_no,
CONCAT(firstname, ' ', lastname) as name,
affiliate_id,
commission,
YEAR(created) as created_year,
MONTH(created) as created_month,
created
FROM orders
WHERE
active = 1 AND
affiliate_id = {$sales_rep_id}
ORDER BY MONTH(created) DESC
");
if (!empty($orders)) {
$total = $this->query("
SELECT SUM(commission) as commission_total
FROM orders
WHERE
active = 1 AND
affiliate_id = {$sales_rep_id}
");
$raw_monthly_totals = $this->query("
SELECT
MONTH(created) as month_no,
SUM(commission) as monthly_commission
FROM orders
WHERE
active = 1 AND
affiliate_id = {$sales_rep_id}
GROUP BY MONTH(created)
");
$monthly_totals = array();
foreach ($raw_monthly_totals as $tot) {
$monthly_totals[$tot['month_no']] = $tot['monthly_commission'];
}
$ret['raw'] = $orders;
$ret['total'] = $total[0]['commission_total'];
$ret['monthly_totals'] = $monthly_totals;
}
}
return $ret;

答案 0 :(得分：2)
当然可以。我添加了一个QueryDesc列来区分查询。
$ret = array(
'raw' => array(),
'total' => '0.00',
'pending' => '0.00',
'monthly_totals' => array()
);
if (!empty($sales_rep_id)) {
$raw_query_data = $this->query("
SELECT
'detail' query_desc,
id,
invoice_no,
CONCAT(firstname, ' ', lastname) as name,
affiliate_id,
commission,
YEAR(created) as created_year,
MONTH(created) as created_month,
created
FROM orders
WHERE
active = 1 AND
affiliate_id = {$sales_rep_id}
UNION ALL
SELECT
'total' query_desc,
NULL id,
NULL invoice_no,
NULL name,
NULL affiliate_id,
SUM(commission) as commission_total,
NULL created_year,
NULL created_month,
NULL created
FROM orders
WHERE
active = 1 AND
affiliate_id = {$sales_rep_id}
UNION ALL
SELECT
'monthly_total' query_desc,
NULL id,
NULL invoice_no,
NULL name,
NULL affiliate_id,
SUM(commission) as commission_total,
NULL created_year,
MONTH(created) as created_month,
NULL created
FROM orders
WHERE
active = 1 AND
affiliate_id = {$sales_rep_id}
GROUP BY MONTH(created)
ORDER BY created_month DESC
");
foreach ($raw_query_data as $data) {
switch ($data['query_desc']) {
case 'detail':
unset($data['query_desc']);
$ret['raw'][] = $data;
break;
case 'monthly_total':
$ret['monthly_totals'][$data['created_month']] = $data['commission'];
break;
case 'total':
$ret['total'] = $data['commission'];
break;
}
}
}
return $ret;
