Hi can anyone help me building below query in laravel Eloquent i am really confuse in using OR condition with between
SELECT * FROM tbl WHERE
existing_start BETWEEN $newSTart AND $newEnd OR
$newStart BETWEEN existing_start AND existing_end
i tried using like
whereBetween('existing_start',[$newSTart,$newEnd])
but have no idea how to use OR
There is an orWhereBetween
method available from the Query Builder, but it is undocumented in the Query Builder Documentation. You can however find it in the Laravel API Documentation.
The explanations below assume that the variables have the following values:
$newStart = '1';
$newEnd = '10';
Unfortunatelly, using orWhereBetween
for the second condition is not applicable in your case, because both whereBetween
and orWhereBetween
will check if a column value is between two input values. This is fine from your first condition since it checks if the existing_start
column value is between $newStart
and $newEnd
. So this is fine:
->whereBetween('existing_start', [$newStart, $newEnd])
As it will be compiled to:
WHERE `existing_start` BETWEEN '1' AND '10'
However your second condition wants to check if an input value from $newStart
is between two column values existing_start
and existing_end
, and there is no Query Builder method that does that. So this will not work:
->orWhereBetween($newStart, ['existing_start', 'existing_end'])
Because it will be compiled to:
OR `1` BETWEEN 'existing_start' AND 'existing_end'
Notice the backticks `
around 1
, because of that MySQL will try to find a column named 1
and throw an error.
So the best option here is to use orWhereRaw
with bindings like this:
DB::table('tbl')
->whereBetween('existing_start', [$newStart, $newEnd])
->orWhereRaw('? BETWEEN existing_start AND existing_end', [$newStart])
->get();
The ?
will be replaced by the value of $newStart
which will be properly quoted and escaped to avoid SQL injection.
Or course there is always the option of having two grouped conditions that check the boundaries, which would be equivalent to your BETWEEN
condition:
DB::table('tbl')
->whereBetween('existing_start', [$newStart, $newEnd])
->orWhere(function ($query) use ($newStart) {
$query->where('existing_start', '<=', $newStart);
$query->where('existing_end', '>=', $newStart);
})->get();
Which will compile to:
SELECT * FROM `tbl`
WHERE
`existing_start` BETWEEN '1' AND '10' OR
(`existing_start` <= '1' AND `existing_end` >= '1')
