I'm trying to query using where statement with 'LIKE', but seems like it is not returning the desired result
my database has a product table, and my query is
Product::where('sku', 'like', "%"."A47ROD01"."%")->get()
while the sku stored in the database is A47ROD
It's normal, you want to search with a LIKE A47ROD, but your request says you must have at least A47ROD01 to find a result, that part A47ROD**01** not match your result.
You need to do
Product::where('sku', 'like', "%A47ROD%")->get()

I am using Laravel, I would like to know how I can obtain this result using DB::
[{'id':1,'name':'A',pictures:[{'property_id':1,'filename':'A01'},{'property_id':1,'filename':'A02'},{'property_id':1,'filename':'A03'}]}]
Right now I'm using eloquent relationships and it works fine but it's slow so I want to do it directly with DB::
PROPERTIES
PICTURES
Is it necesary to make it exactly in that format?
To just get all data you want as one object try something like:
DB::table('properties')
->join('pictures', 'property_id',
'=', 'properties.id')
->select('*')
->get()->toArray();
I want to find by letter customer's first_name on my 'customers' table.
And the only thing that I get is an empty array.
For instance, I put in the parameter 'q' value 'E' to get customer Elena from my database by I get an only empty array.
I use the following code to get first_name :
$search = Input::get('q');
if($search)
{
$customers = Customer::all()->where('full_name', 'LIKE', "%{$search}%");
return ($customers);
}
Can someone help me?
Your query don't work because you are calling the all() method before the where(). That's actually not wrong, but it have different behavior.
When you call all(), it actually does the SQL query. After that, any chained methods are being called into a Eloquent Collection class, and it also have a where method, but that's simpler since it runs on PHO instead of running on SQL.
Since the collection's where() method doesn't support LIKE operator, it's probably searching for a value that is exactly %E%.
Hope it can help you understanding why your query doesn't work as expected.
Try this
$customers = Customer::where('full_name', 'LIKE', "%{$search}%")->get();
Laravel Eloquent
I'm trying to get the most recent record for each candidate_id from a ìnterviews` table.
This is what I want to achive:
I'm using Eloquent on laravel and have already tried this methods (with and without eloquent):
$candidates = DB::table('interviews')->select('interviews.*', 'i2.*')
->leftJoin('interviews as i2',
function ($join) {
$join->on('interviews.candidate_id', '=', 'i2.candidate_id');
$join->on('interviews.created_at', '<', 'i2.created_at');
}
)
->whereNull('i2.candidate_id')
->get();
and with eloquent I've tried this:
$candidates = Interview::leftJoin('interviews as i2',
function ($join) {
$join->on('interviews.candidate_id', '=', 'i2.candidate_id');
$join->on('interviews.created_at', '<', 'i2.created_at');
}
)->whereNull('i2.candidate_id')
->get();
If I change get() to toSql() I have exactly the same query that's shown on the above image, but running on laravel I'm getting always these results (this using the first method, with query builder):
Anyone know why I get this results? Is hard to understand that laravel is doing the same query that I do in HeidiSql but I get diferent results :(
Any tip?
Thanks in advance!
Because you are using ->select('interviews.*', 'i2.*') combined with ->whereNull('i2.candidate_id') I am assuming the second select parameter is overriding all fields on the interviews table with nulls, try reversing the order to ->select('i2.*','interviews.*') or not use the i2.* at all.
This is because the output ignores the alias and only uses the fieldname as element key in the returned collection.
Hope it works.
Perfect case scenario you pick the exact columns you want from each of the joined tables for e.g. it may go like this: table1.id,table1.column1,table1.column2,table2.column2 as smth_so_it_doesnt_override
I have an laravel eloquent select statement which looks like this:
$test = Test::with(['a.b.companies']) .. and so on
Now, I want to return results for this query based on some company names in companies table.
I tried to write a where clause with various trial and errors but it doesn't work. I am new to laravel and mysql. Any help in the right direction will be good. thanks.
You may use where, for more reference : - Eloquent ORM
$test = Test::where('company_name1', '=', $company_name1)->orWhere('company_name2', '=', $company_name2)->get();
I have such query:
Tournament::has('participations', '<', '2')->get();
How can I replace constant number '2' on tournament's column named slots ?? I would like retrieve only these tournaments which have least participants than slots in tournament.
Let's start by using the column name instead of "2". Like you would do in "normal" SQL
Tournament::has('participations', '<', 'slots')->get();
Now, you don't even have to try that because it won't work. But why's that? Because Laravel treats slots like a string and escapes it so SQL does as well.
What you need to do, is use DB::raw(). raw makes sure Laravel changes nothing and just injects it into the SQL query
Tournament::has('participations', '<', DB::raw('slots'))->get();
Update
After some trying out I found this: (Its not very pretty but the only way I got it working)
$subquery = function($q) use ($uid){
$q->where('player_id', $uid);
}
Tournament::whereHas('participations', $subquery)
->whereHas('participations', $subquery, '<', DB::raw('slots'))
->get();
The first whereAs checks for count(*) > 0, the second count(*) < slots and the subquery filters by player id.
