Eloquent or Query Builder: When to Use Which?

[@josephnduati1214]

Thank you, great content as always. My experience: 1. Simple INSERTS: Eloquent 2. Complex INSERTS: Query Builder 3. Simple READS : Eloquent 4. Complex READS : Query Builder 5. Very Complex READS : Raw SQL What i miss out for not using eloquent fully is eloquent convenience/magic such as model events. I also find myself not using Eloquent Relationships.

One thing you missed is that when you use query builder you don't get advantages of model events

[@flying_david]

[@JLDRPT]

Well, in my case, I like to use Raw Queries. Correct me if I'm wrong, but nothing can be more performative than Raw Queries, because I think there are almost no layers betweeen Laravel em PHP PDO/MySQLi/whatever. Of course the table changing name is more effective with tradicional model approach, but you can always refactor you code with your editor. For me is not a big deal. And one very important downside of using only EloquentORM or Query Builder is that this is not available on the tools you use to manage directly you database on the server (SequelPro, HeidiSQL, PHPMyAdmin, etc.) Therefore, there can be a time when you will forget how to write propor SQL queries because you are used to run them with Query Builder. Just my 5 cents

[@hostname47]

Totally agree I hate these complications esp with subjoins and where clauses in query builder, they just complicate things. If we are backend devs we MUST know how to use sql syntax; and everyone tell me to use eloquent or QB to make code readable means bull**it

[@abelenocrodriguez]

I think it all depends on the case, but for the most part for general use it is better eloquent.

I normally use Eloquent. But when I do charts, reports, export and etc, query builder rules.

[@GergelyCsermely]

Thank You. I'm getting answers for my questions. Ha suffered a lot with Eloquent - at the end i managed to solve it that i prepared a view in MySQL and joined this with raw query. I needed sums, with group by with 2 additional joined tables.

[@oliverkobing4726]

I've had many situations, where I have had to switch to DB facade. More complicated queries usually tend to be much slower in Eloquent than using the facade or doing raw queries. Eloqent is programmer-friendly.

[@RobinsonMoscoso]

In some cases I used Stored Procedures for complex queries, and the performance is better. But the daily work, I use eloquent.

[@aibarra11]

Do you have a common workflow for moving to stored procedures? I was recently considering this for a project I'm working on, but wasn't sure if laravel supported these types of migrations. I was able to get by with a custom query and redis caching. It wasn't an often updated data set

[@faustoffff]

You can combine some advantages of Eloquent Builder and both less memory usage like using Query Builder (without hidrate Eloquent models) by using toBase() method of Eloquent Builder.

[@robdorn420]

When you use eager loading with eloquent the 'in' clause is used. In bigger systems the 'in' clause may easily have more than a thousand items (a company can sell more than 1000 articles). If so you cannot use it with an Oracle DB (12c) because it has a limit of 1000 items in an 'in' clause.

[@OLIV3R_YT]

If I remember correctly Laravel will split the IN clause into multiple IN clauses each not exceeding 1000 entries. I could be wrong though.

[@robdorn420]

@@OLIV3R_YT That would be a new feature then, because that wasn't the case about a year ago. I found out because Oracle is our primary db. On one side it would be great if Laravel would split it up; on the other side: more than a 1000 items in an 'in' clause.... doesn't feel great in my mind.

Lazy collection is automatic?

[@leonardoldr]

You can easily resolve this by using chunks. Even though above 1.000 records per time your server memory will feel it's heart being smashed with a giant rock. :(

[@robdorn420]

@@leonardoldr This is not about the amount of records that is retrieved, but the number of entries in the where ... in (1, 2, 3, max 1000 in Oracle). It is the eager loading of Laravel that creates the 'in' clause. That why we use Query builder and Raw queries. (And yes, we use chunking).

[@marcincook]

My case IF: (1) - I not need Model and relations for one thinks like this scenario DB::connection('sqlsrv') ->table('places') ->leftJoin('operators', 'places.OperatorID', '=', 'operators.ID') ->leftJoin('users', 'operators.ID', '=', 'users.OperatorID') ->select('operators.Nick', 'users.ID as UserID') ->where('places.PIN',$pin) ->where('operators.Locked', 0) ->first(); (2) - Must Call to stored Procedure in Sql Server like this scenario many triggers, procedures and a loot in Database $result = DB::connection("sqlsrv")->statement("exec p_SaveOrderWithRelation @cOrderID='{$order->id}', @cPaymentID='{$payment->id}', @cShiftID='{$shift->id}', @cSimple=0"); return $result->QueneID; (3) - If Underestand SqlSerwer and have Expirience in sql Querys, reports and advanced querys in T-SQL and have a loot of logic in Database like triggers, functions... Query Builder is more natural to build your result data if you have 100 tables and more, and aplications is only web part of full ecosystem (Desktop, Web, Mobile, Devices...) Elequent for all in own aplication QueryBuilder for strong and complicated relations like big reports

[@andreybalin9314]

All rights! When working with t-sql or Pl/sql, then use Orm is total fail. Model must get data from View (DB) or Stored procedure like simple Select.

[@ktotut5378]

You can use Model::table() instead of hardcoded table name.

[@gillesashley9314]

What makes laravel special is been able to combine power, performance and ease of use. I know there are other frameworks that perform much better than laravel, but are way much difficult to use.

[@alexrusin]

I think we are putting a cart in front of the horse here trying to see what is faster or more readable. Decision what to use should depend on application requirements, user stories, entity objects.

Hello sir, your tutorials are very helpful for me as a beginner in laravel. May I ask, do you have any student qr code attendance system demo project provided in this channel?

[@DanielPoliFabro]

Mr. Korop, first of all thank you so much for the videos. You really are a good teacher. Quick question: Im using query builder to fill report data, but when I need to use a related model currency field Laravel casts it as string. If I want the correct casting I need to insert the related field in the casts array of the main model. Is it a good pratice? Shouldnt the cast array content only the model fields? tks in advanced.

[@PezhvakIMV]

One of the main reasons i use eloquent is events. you forgot to mention that. in lots of situations we cleanup system using eloquent events, like uploaded image files.

[@gautammenariya8292]

Awesome tutorial as always. Keep it up👍👍👍👍

[@engramiribrahim]

Thanks for your Video, i want a video from you-> about curd operation (edit), actually how to put old value on combo box, using eloquent and db query both

[@MiguelFelipeCalo]

This varies more if it has a hasMany relationship.

[@raventor]

You can make table names dynamic when using query builder. So you dont have to update every query when the table name is changing. $users = DB::table(with(new User())->getTable())->get(); Or you can have a static method in the models, and delegate this logic there and use like this: $users = DB::table(User::getTable())->get();

[@Ballltas]

If you use some method that that eloquent does not have even if you call it via model facade it falls back to query builder. Like Product::join('products_categories')... so in some sence the diff is really negligible how you access it. $product->category->name or $product->category_name. So its not really an advantage. With our IDEs you can easily find all the cases where you have to change. So one line change versus 20 lines of change its not so different. So we are talking performance vs how quick you can change something for developer. But the probability of this needs changing is very low. So I don't even use eloquent unless it already used and I need to add some stuff.

[@javiershaka]

excellent video, a couple of months ago looking for how to improve my performance I saw your video of refactor controller and you post When to Use Dependency Injection, Services and Static Methods, I would like to know when it is good to use these things also adding resources and collections all attached in a project

[@PovilasKorop]

For those dependency injections and design patterns in general, there's no ONE answer on when to use them, you need to feel it when your project gets bigger and harder to control, then you need SOME patterns. Maybe my this article will help: blog.quickadminpanel.com/laravel-when-to-use-dependency-injection-services-and-static-methods/

[@javiershaka]

Thanks, I'll give you another read in more detail.

[@amirafatnassi4922]

Thank you for sharing , this is very intersting. However, i had to switch from elequent to query builder because it was giving me the wrong results (i'm sure there's a fix that i could'nt find ). My table has a string id composed of numbers and letters such as 1234M001, the elequent truncates the id and return only 1234.

[@thegreytangent]

I always use eloquent when I modify the data in db like creating or updating. I use Query builder when extracting data in database

[@kcastle]

2:03 Isn't it the other way around? The Eloquent query is "faster" / uses less database time because it's 27.37 + 4.02 = ~31ms while the Doctrine query with the join uses 52.5ms of database time. This makes the Eloquent query more scalable (only locking one table at a time too I think?).

[@elilopezdev]

Excellent advice! Thanks for the hard work.

[@waqasmushtaq81]

Eloquent is all about readibility and managing relationships more easily. If you have lots of tables with dozans of relationships then Eloquent is better option for sure.

[@kreaweb-be]

I use query builder a lot. But only on MySQL VIEWS. This way MySQL can do what it does best, all the heavy lifting. For normal CRUD, I always use Eloquent.

[@devKenny]

I used the query builder if I didn't need the model. I needed the stdClass object because it was convenient to work with.

[@TonyByng]

DB all the way with any speed requirements and Eloquent for Crud. We regularly interrogate tables with millions of records and queries were rewritten to use DB for speed. Also that same database imports 100,000 records per day and changing to DB meant we saved 50 percent of the daily load time. However crud, where speed isn't an issue, it's much easier to use eloquent.

[@msw0629]

When you say eloquent for CRUD, that basically covers every aspect of queries, doesn’t it? So what do you mean by ‘DB all the way’? Thanks in advance I’m just confused with this comment but I’m interested to know your thoughts since you do this often.

[@TonyByng]

@@msw0629 thanks for the question. When I said crud I should have said user interaction, like editing, creating, deleting one record via a user interface, where a process taking 0.25 seconds instead of 0.1 seconds won't be noticeable but if I'm importing thousands of records then I won't use eloquent because 10,000 lots of 0.15 seconds (for example) is an awful lot of additional seconds.

[@msw0629]

@@TonyByng Thanks Tony for the prompt reply and clarification. Would you care to shed some light on this: eloquent or DB when loading a collection? For example, let’s say we are loading 50 tasks from a table with 10k records (which is a pretty common scenario for task index page), would it be better to use DB query? This may be from the servers angle as such request can be frequent and consuming, e.g. every time after deleting/edit a task, send an API request to reload the task table. Thank you for your time.

[@TonyByng]

@@msw0629 personally I'd use eloquent for that. That would be essentially one query that selects 50 records from a table whereas if I was updating those 10,000 task records every day then I would use DB. Ultimately anything that is more than using PDO is potentially adding more processing to the request so if you are ultra sensitive to speed you wouldn't use any laravel routines. It's just weighing up whether in any particular scenario you are more sensitive to speed. And if you are needing the quickest response I would start caching where appropriate but for index pages with a table of 50 paginated records then I'd still use eloquent. Hope that helps

[@msw0629]

@@TonyByng It does. Thanks for your insights on Eloquent and cache. One last question: when the requested data requires comprehensive relationships (still 50 out of 10k records table, but use query builders that includes 10 joined tables). In this case, I suppose your expertise would favor DB?

[@syahnurnizam1755]

query builder is useful if I want to generate reports where the queries require multiple joins from different tables. I also use them when I need to use complex nested queries. On rare occasion, query builder is much easierto use than eloquent when dealing with complex queries.

[@charanarora3085]

If you have relationship defined and schema is perfectly build then elequent is better !

[@hakizuri]

In page where need to load alot of information such as dashboard, export to excel, can use Query Builder or Raw SQL. For page such as product page, can use eloquent with paginate so will break the data to small rows althought the the product got 1 millions rows.

[@infotex138]

[@mityaboy4639]

With all fairness that QueryBuilder should be in the model too as it has no place in the controller. then you could use $this->table (or self::) and you solved the "rename table" problem without much of a hassle. not as if renaming a table would be a frequent task. On the other hand this is just ONE query, imagine running twice as slow on every one of them. and eating up 5 times the memory. Yes there are sacrifices on the developer side if you use DB query but keeping your site lightning fast vs "well its easier to read" is not gonna win much fight with the management and with the endusers.. "sure it takes 5 seconds to render, but boy i can read the code with no effort" i am all in love with Laravel, but performance is key in every application, and running twice as slow quickly adds up. And the issue is that this masquerades the problem so well that less experienced developers will have no idea where the code gets so slow as they expect that laravel is superfast under the hood. (which is true most of the time) (note : i love automation, and i love that frameworks making life easier and coding faster, and would be super happy to sacrifice *some* performance, but this example shows that it is not "some" it is a lot. - and i know you can wrap things up and store them in cache for faster access, my point is that with no cache (or empty) things could get dreadfully slow and most of junior / mid devs wont have a clue, and they will accept that pulling 1k of data from a DB is slow, when the truth is DB could handle much bigger datasets much faster) anyway: keep up the good work, your videos are good and helpful.

I have one question with Eloquent, how return random row with where. User::where('role', $role)->inRandomOrder()->first() or User::where('role', $role)->random()->first()? These both ways are correct, just using different approaches under the hood or one of them is incorret?

[@gaffygaffy6539]

that second query you posted is wrong and will throw an error, there is no random() method in the query builder. What I think you meant was User::where('role, $role)->get()->random()->first(), as the ->get() returns a collection and ->random() is a method that can be called on a collection. ->inRandomOrder() adds to the query that get build and adds a RAND... function to the underlying sql query, and thus the processing to pushed to SQL rather than in your PHP that the ->random() call does since its acting on the collection in the PHP. So do you want the load in SQL or PHP? Generally you want to use SQL more as the database is built to be efficient at working with data than PHP is. So ->inRandomOrder() is probably the best option and I would say the better practise.
