How to bind datetime field between two string value - php

Question

I have method like this :
public function getCustomDateOrders(string $startDay,string $endDay,string $food) :array
{
$result = $this->_em->createQueryBuilder()
->select
(
'OrderEntity.name'
'OrderEntity.created'
)
->from($this->entityClass , 'OrderEntity')
->leftJoin(
'Directory\Food',
'Food',
'with',
'Food.id = OrderEntity.FoodId '
)
->where("Food.id =:food")
->andWhere("OrderEntity.status =:active")
->andWhere("startDate<:OrderEntity.orderCreated >:endDay")
->getQuery()
->setParameters([
"food" => $food,
"active" => 1,
"startDate" => $startDay,
"endDay" => $endDay
])
->getScalerResult();
->getScalarResult();
}
I have couple of values :
$startDay is equal to "2016-010-17 00:00:00" (string)
$endDay is equal to "2016-10-03 00:00:00" (string)
And also order.created (one of order's fields) is datetime.
I want to fetch order from order entity which has created field is between $startDay and $endDay. How to solve it?

Answer 1

Use between:
public function getCustomDateOrders(string $startDay,string $endDay,string $food) :array
{
$result = $this->_em->createQueryBuilder()
->select
(
'OrderEntity.name'
'OrderEntity.created'
)
->from($this->entityClass , 'OrderEntity')
->leftJoin(
'Directory\Food',
'Food',
'with',
'Food.id = OrderEntity.FoodId '
)
->where("Food.id =:food")
->andWhere("OrderEntity.status =:active")
->andWhere("OrderEntity.orderCreated between :startDay and :endDay")
->setParameters([
"food" => $food,
"active" => 1,
"startDay" => $startDay,
"endDay" => $endDay
])
->getQuery()
->getScalerResult();
}

And that is why we don't store dates as strings. You can still convert the string inside the query, so don't just turn off the computer yet.
Use the str_to_date() function:
Lets translate it into SQL:
select * from yourtable
where created > str_to_date(start_day, '%Y-%m-%d %H:%i:%s')
and created < str_to_date(end_day, '%Y-%m-%d %H:%i:%s')
There we go. Give me all the rows which where created after the start_date and before the end date.
The better way would probabbly be converting your strings to dates and the use between like sugested.
