How to select specific columns in laravel eloquent

Question

lets say I have 7 columns in table, and I want to select only two of them, something like this

SELECT `name`,`surname` FROM `table` WHERE `id` = '1';

In laravel eloquent model it may looks like this

Table::where('id', 1)->get();

but I guess this expression will select ALL columns where id equals 1, and I want only two columns(name, surname). how to select only two columns?

Answer 1

You can do it like this:

Table::select('name','surname')->where('id', 1)->get();

Answer 2

Table::where('id', 1)->get(['name','surname']);

Answer 3

By using all() method we can select particular columns from table like as shown below.

ModelName::all('column1', 'column2', 'column3');

Note: Laravel 5.4

Answer 4

You can also use find() like this:

ModelName::find($id, ['name', 'surname']);

The $id variable can be an array in case you need to retrieve multiple instances of the model.

Answer 5

You first need to create a Model, that represent that Table and then use the below Eloquent way to fetch the data of only 2 fields.

Model::where('id', 1)
         ->pluck('name', 'surname')
         ->all();

Answer 6

Also Model::all(['id'])->toArray() it will only fetch id as array.

Answer 7

Get value of one column:

Table_Name::find($id)->column_name;

you can use this method with where clause:

Table_Name::where('id',$id)->first()->column_name;

or use this method for bypass PhpStorm "Method where not found in App\Models":

Table_Name::query()->where('id','=',$id)->first()->column_name;

in query builder:

DB::table('table_names')->find($id)->column_name;

with where cluase:

DB::table('table_names')->where('id',$id)->first()->column_name;

or

DB::table('table_names')->where('id',$id)->first('column_name');

last method result is array

Answer 8

You can use get() as well as all()

ModelName::where('a', 1)->get(['column1','column2']);

Answer 9

From laravel 5.3 only using get() method you can get specific columns of your table:

YouModelName::get(['id', 'name']);

Or from laravel 5.4 you can also use all() method for getting the fields of your choice:

YourModelName::all('id', 'name');

with both of above method get() or all() you can also use where() but syntax is different for both:

Model::all()

YourModelName::all('id', 'name')->where('id',1);

Model::get()

YourModelName::where('id',1)->get(['id', 'name']);

Answer 10

To get the result of specific column from table,we have to specify the column name.

Use following code : -

   $result = DB::Table('table_name')->select('column1','column2')->where('id',1)->get();  

for example -

$result = DB::Table('Student')->select('subject','class')->where('id',1)->get();  

Answer 11

use App\Table;
// ...
Table::where('id',1)->get('name','surname');

if no where

Table::all('name','surname');

Answer 12

Also you can use pluck.

Model::where('id',1)->pluck('column1', 'column2');

Answer 13

If you want to get a single value from Database

    Model::where('id', 1)->value('name');

Answer 14

You can use Table::select ('name', 'surname')->where ('id', 1)->get ().

Keep in mind that when selecting for only certain fields, you will have to make another query if you end up accessing those other fields later in the request (that may be obvious, just wanted to include that caveat). Including the id field is usually a good idea so laravel knows how to write back any updates you do to the model instance.

Answer 15

You can get it in various ways. Some of these are shown below-

//Eloquent: Get specific columns (not all the row). Pluck returns an array.
Model::where('id', 1)->pluck('name', 'surname');
// If you only want to get the result value:
Model::where('id', 1)->value('name');

Or,

Model::where('id', 1)
     ->pluck('name', 'surname')
     ->all();

Or,

ModelName::all('column1', 'column2', 'column3');

Or,

ModelName::find($id, ['name', 'surname']);

Answer 16

you can also used findOrFail() method here it's good to used

if the exception is not caught, a 404 HTTP response is automatically sent back to the user. It is not necessary to write explicit checks to return 404 responses when using these method not give a 500 error..

ModelName::findOrFail($id, ['firstName', 'lastName']);

Answer 17

While most common approach is to use Model::select, it can cause rendering out all attributes defined with accessor methods within model classes. So if you define attribute in your model:

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class User extends Model
{
    /**
     * Get the user's first name.
     *
     * @param  string  $value
     * @return string
     */
    public function getFirstNameAttribute($value)
    {
        return ucfirst($value);
    }
}

And then use: TableName::select('username')->where('id', 1)->get();

It will output collection with both first_name and username, rather than only username.

Better use pluck(), solo or optionally in combination with select - if you want specific columns.

TableName::select('username')->where('id', 1)->pluck('username');

or

TableName::where('id', 1)->pluck('username'); //that would return collection consisting of only username values

Also, optionally, use ->toArray() to convert collection object into array.

Answer 18

If you want to get single row and from the that row single column, one line code to get the value of the specific column is to use find() method alongside specifying of the column that you want to retrieve it.

Here is sample code:

ModelName::find($id_of_the_record, ['column_name'])->toArray()['column_name'];

Answer 19

ModelName::find($id, ['name', 'surname']);

Answer 20

->get() much like ->all() (and ->first() etc..) can take the fields you want to bring back as parameters;

->get/all(['column1','column2'])

Would bring back the collection but only with column1 and column2

Answer 21

You can get it like

`PostModel::where('post_status', 'publish')->get(['title', 'content', 'slug', 'image_url']`)

link

Answer 22

You can use the below query:

Table('table')->select('name','surname')->where('id',1)->get();

Answer 23

If you need to get one column calling pluck directly on a model is the most performant way to retrieve a single column from all models in Laravel.

Calling get or all before pluck will read all models into memory before plucking the value.

Users::pluck('email');
