i try to get results from table with multiple where and/or clauses.
My SQL statement is:
SELECT * FROM tbl
WHERE m__Id = 46
AND
t_Id = 2
AND
(Cab = 2 OR Cab = 4)
How i can get this with Laravel Eloquent?
My Code in Laravel is:
$BType = CabRes::where('m_Id', '=', '46')
->where('t_Id', '=', '2')
->where('Cab', '2')
->orWhere('Cab', '=', '4')
->get();
Using advanced wheres:
CabRes::where('m__Id', 46)
->where('t_Id', 2)
->where(function($q) {
$q->where('Cab', 2)
->orWhere('Cab', 4);
})
->get();
Or, even better, using whereIn():
CabRes::where('m__Id', 46)
->where('t_Id', 2)
->whereIn('Cab', $cabIds)
->get();
Also, if you have a variable,
CabRes::where('m_Id', 46)
->where('t_Id', 2)
->where(function($q) use ($variable){
$q->where('Cab', 2)
->orWhere('Cab', $variable);
})
->get();
When we use multiple and (where) condition with last (where + or where) the where condition fails most of the time. for that we can use the nested where function with parameters passing in that.
$feedsql = DB::table('feeds as t1')
->leftjoin('groups as t2', 't1.groups_id', '=', 't2.id')
->where('t2.status', 1)
->whereRaw("t1.published_on <= NOW()")
>whereIn('t1.groupid', $group_ids)
->where(function($q)use ($userid) {
$q->where('t2.contact_users_id', $userid)
->orWhere('t1.users_id', $userid);
})
->orderBy('t1.published_on', 'desc')->get();
The above query validate all where condition then finally checks
where t2.status=1 and
(where t2.contact_users_id='$userid' or where t1.users_id='$userid')

I want to make a count by the first letters... I have this column
I would like to count each OE rows and each GICS rows
I'm working with this query
$data4 = DB::table('incidencias')
->select(DB::raw('grupo_asig as grupo_asig'), DB::raw('count(*) as number'))
->whereNotIn('grupo_asig', [''])
->groupBy('grupo_asig')
->orderBy('number', 'desc')
->get();
Use CASE WHEN and count the field like OE and ASIG
$data4 = DB::table('incidencias')
->select(DB::raw("(CASE WHEN grupo_asig LIKE 'OE%' THEN 'OE'
WHEN grupo_asig LIKE 'GICS%' THEN 'GICS'
END) AS grupo_asig_type"),
DB::raw('COUNT(*) as number'))
->whereNotIn('grupo_asig', [''])
->groupBy('grupo_asig_type')
->orderBy('number', 'desc')
->get();
You should try to use the [LIKE][1] function then and add it to your query:
->where('grupo_asig', 'like', 'OE%')
->where('grupo_asig', 'like', 'GICS%')
Edit:
I tried a lot around and came to this solution and made a SQL fiddle: http://sqlfiddle.com/#!9/06a39b/8
Does it help you?
You could use Collections. No real need to change your query much.
$data4 = DB::table('incidencias')
->select('grupo_asig')
->selectRaw('count(*) as number'))
->whereNotIn('grupo_asig', [''])
->groupBy('grupo_asig')
// ->orderBy('number', 'desc') Unless you use this array somewhere, it's not needed.
->get();
use Illuminate\Support\Str;
...
// php >= 7.4.0
$oe_count = $data4->filter(fn($data) => Str::startsWith($data->grupo, 'OE '))->count();
$gigs_count = $data4->filter(fn($data) => Str::startsWith($data->grupo, 'GIGS '))->count();
// php < 7.4.0
$oe_count = $data4->filter(function ($data) {
return Str::startsWith($data->grupo, 'OE ');
})->count();
$gigs_count = $data4->filter(function ($data) {
return Str::startsWith($data->grupo, 'GIGS ');
})->count();
Starting with Laravel 6, you can also use cursor() instead of get() in your query to return a LazyCollection. It's faster for this scenario.
I would suggest using a query for that:
refer to this answer
SELECT
LEFT(grupo_asig, 1) AS first_letter,
COUNT(*) AS total
FROM incidencias
GROUP BY first_letter
LARAVEL 5.4 (but probably it's a more general SQL question)
Hello! I have a table with a structure:
Suppose it's my model 'Table'.
I want a query which:
uses (receives) variables :
$id of array ['id', 'string', integer]
where string is '<' or '>'
$status_not_bad = bool;
(if true - include all rows where 'status' !== 'bad' AND 'status' IS NULL);
for example, we are given:
$id = [['id', '>', 0]];
$status_not_bad = true;
Table::thisquery() ... ->get();
"get rows where status is not bad and id > 0" returns rows 1 and 3.
but if we given:
$id = [['id', '<', 3]];
$status_not_bad = true;
Table::thisquery() ... ->get();
"get rows where status is not bad and id < 3" returns row 1
(it should be same query which return those results using those variables).
Probably you end with something like this:
if ($status_not_bad) {
$nStatus = 'bad';
} else {
$nStatus = 'good';
}
Table::thisquery()->where('status', '<>', $nStatus)
->whereNotNull('status')
->where($id[0], $id[1], $id[2])
->get();
But it would be a good idea to check $id keys first.
Since row id = 3 you need <= in your where statement to have that row included in the result set
$id = ['id', '<=', 3];
So, I this works:
$chain = Sample::when($status_not_bad, function($query){
return $query->where('status', '<>', 'bad')
->orwhereNull('status');
})
->where([$id])
->get();

I've never used laravel before so my syntax could be off, but I know you want to use MySQL's ifNull function for this:
Table::where([['id', '>', 0], ['number', '>', 2])->whereRaw("IfNull(status, 'blah') <> 'bad'")->get();
Just chain your ->where() clauses. Maybe also consider wrapping them to prevent conflicting with any additional:
$results = Table::where("id", ">" 0)
->orWhere("number", ">", 2)
->orWhereNull("status")
->get();
Or, wrapped:
$results = Table::where(function($query){
$query->where("id", ">" 0)
->orWhere("number", ">", 2)
->orWhereNull("status");
})->get();
If you want to see what the actual query you're executing is, replace ->get() with ->toSql(), and use dd($result);:
$results = Table::where(...)->toSql();
dd($results);
Edit: Sounds like we need multiple wrapping queries, due to multiple conditions:
$results = Table::where(function($query){
$query->where("status", "!=", "bad")
->where("id", "<", 3); -- "status is not bad and id < 3"
})->orWhere(function($query){
$query->where("status", "!=", "bad")
->where("id", ">", 0); -- "status is not bad and id > 0"
})->get();
That should handle paired conditions as noted in your comment.
Is there some elegant way to write the following query in eloquent? I would like to avoid using the raw query:
results(id, data)
result_filters (id, result_id, filter_id, value)
SELECT * FROM results, result_filters as age, result_filters as followers
WHERE age.result_id = results.id
AND followers.result_id = results.id
AND age.filter_id = 2
AND age.value > 90
AND followers.filter_id = 6
AND followers.value < 10000
If you are using the laravel eloquent
your model relation could be like
model Result:
public function resultFilters()
{
return $this->hasMany('App\ResultFilter');
}
model ResultFilter:
public function result()
{
return $this->belongsTo('App\Result','result_id');
}
try the below code:
$result = Result::find(1);
$data = $result->resultFilter()
->whereIn('filter_id',[2,6])
->whereBetween('value',[90,10000])
->get();
What do you think? It's uses DB::raw but it works
$data = DB::table(DB::raw("results, result_filters as age, result_filters as followers "))
->select(DB::raw("* "))
->where('age.result_id', 'results.id')
->where('followers.result_id', 'results.id')
->where('age.filter_id', 2)
->where('age.value', '<', 90)
->where('followers.filter_id',6)
->where('followers.value','<',10000)
->get();
Following query returning six values
SELECT tbl_start FROM timetable inner join route ON tbl_rte_id = id WHERE rte_origin = "UL" and rte_destination = "HW" ORDER BY(tbl_start) DESC;
And my laravel code is returning only one value
$tables = Timetable::join('route', 'tbl_rte_id', '=', 'id')
->where('rte_origin', $origin, 'AND')
->where('rte_destination', $destination)
->orderBy('tbl_start', 'desc')
->get();
foreach ($tables as $table) {
$result[$table->id] = $table->tbl_start;
}
This laravel code is not similar or similar. Can anyone help me.
Change this part:
->where('rte_origin', $origin, 'AND')
// to:
->where('rte_origin', $origin)
It will know by default that it's AND operator
And if you want to provide this operator, then do this:
->where('rte_origin', '=', $origin, 'AND')
You may try something like this:
$tables = Timetable::join('route', 'tbl_rte_id', '=', 'timetable.id')
->where('rte_origin', $origin)
->where('rte_destination', $destination)
->orderBy('tbl_start', 'desc')
->get()->lists('tbl_start', 'id');
The $tables will contain an array of id => tbl_start pairs.
Add a listener in your routes.php
Event::listen('illuminate.query', function($sql){
var_dump($sql);
});
Then execute both queries and check if you have the same result
