我想为推荐的换油设置预定的电子邮件。为此,我需要从最近一次换油超过3个月前的订单项表中进行选择。我需要一个条件来忽略当前选定的客户行,其中3个月前购买了换油。我该如何添加这个条件?
$search_term = 'oil change';
$date = new DateTime('-3 months');
$users = $this->prospectInstance->getDatabase()->table('LineItems')
->join('WorkOrder', 'WorkOrder.id', '=', 'LineItems.order_id')
->join('Customer', 'Customer.customer_id', '=', 'WorkOrder.customer_id')
->where('LineItems.line_type', 'like', "%$search_term%")
->where('WorkOrder.create_date', '<=', $date)
// this block produces errors
->whereNotIn('Customer.customer_id', function($query) use ($search_term, $date)
{
return $query->where('LineItems.line_type', 'like', "%$search_term%")
->join('WorkOrder', 'WorkOrder.id', '=', 'LineItems.order_id')
->join('Customer', 'Customer.customer_id', '=', 'WorkOrder.customer_id')
->where('WorkOrder.create_date', '>=', $date);
})
->orderBy('WorkOrder.create_date', 'DESC')
->groupBy('Customer.customer_id');
表格结构:
LineItems
order_id
line_type
WorkOrder
id
customer_id
create_date
Customer
customer_id
编辑:我能够使用下面的建议使用两个单独的查询来完成此任务,但我想知道是否有一个查询可以创建以实现相同的结果:
$search_term = 'oil change';
$date = new DateTime('-3 months');
$base_query = $this->prospectInstance->getDatabase()->table('LineItems')
->join('WorkOrder', 'WorkOrder.id', '=', 'LineItems.order_id')
->join('Customer', 'Customer.customer_id', '=', 'WorkOrder.customer_id')
->where('LineItems.line_type', 'like', "%$search_term%")
->orderBy('WorkOrder.create_date', 'desc')
->groupBy('Customer.customer_id');
$recent = clone $base_query;
$users = clone $base_query;
$recent->where('WorkOrder.create_date', '>', $date)
->select('Customer.customer_id');
$users->where('WorkOrder.create_date', '<=', $date)
->whereNotIn('Customer.customer_id', $recent->lists('customer_id'));
答案 0 :(得分:1)
我认为这样可行,但显然没有经过测试:
$users = $this->prospectInstance->getDatabase()->table('Customer')
->join('WorkOrder', 'WorkOrder.customer_id', '=', 'Customer.customer_id')
->join('LineItems', 'LineItems.order_id', '=', 'WorkOrder.id')
->where('LineItems.line_type', 'like', "%$search_term%")
->whereNotIn('Customer.customer_id', function($query) use ($date, $search_term)
{
$query->select('Customer.customer_id')
->from('Customer')
->join('WorkOrder', 'Customer.customer_id', '=', 'WorkOrder.customer_id')
->join('LineItems', 'WorkOrder.id', '=', 'LineItems.order_id')
->where('WorkOrder.create_date', '>', $date)
->where('LineItems.line_type', 'like', "%$search_term%");
})
->orderBy('WorkOrder.create_date', 'desc')
->groupBy('Customer.customer_id');
