Route::get('/test', function(){
return DB::table('table')->where_not_null('column')->get();
});
In Laravel 4 I have the following route, obviously with table and column replaced. I had it in the controller but it wasn't working, so I moved it to a test route.
The error I am getting is:
SQLSTATE[42S22]: Column not found: 1054 Unknown column '_not_null' in 'where clause' (SQL: select * from `table` where `_not_null` = column)
https://tower.la.utexas.edu/docs/database/fluent#where
Documentation says:
return DB::table('table')->where_null('column')->get();
It should be
return DB::table('table')->whereNull('column')->get();
Or
return DB::table('table')->whereNotNull('column')->get();
You have used where_not_null.This is the right reference.
See the proper writing for that: http://laravel.com/docs/queries#selects
DB::table('table')->whereNotNull('column')->get();
The documentation states that following the table declaration you should put the query builder information, where_null, where_not_null, where_in.
However that doesn't work. I'm not sure why, it makes no sense, and is frustrating. However, this does work.
return DB::table('user')->whereuserName('not_null')->get();
By placing the column name where the documentation says to put the query, and the query where the documentation says to put the column you are able to execute your query. To note, camel case is converted to snake case in the query, so the column has to be named user_name.
I am posting this because I attempted googling it and was not able to find anything.

Given this code
$mapper->reset();
$mapper->set( 'foo', 'bar' ); // <--- Error here: `foo` does not exists in the table
$mapper->insert();
Where foo is a column that does not esist in the mapped table I get this error
Internal Server Error
SQLSTATE[42S22]: Column not found:
1054 Unknown column 'bar' in 'field list'
[/var/www/example.com/html/lib/php/fatfreeframework/DB/SQL.php:230]
The error message is misleading in fact the non existent column is foo, not bar: the latter is the value that has been attempted to set to the non-existent column.
Why does this happen? Is there a way to fix this?

By opening a issue on github I got the answer from #ikkez:
This is currently the expected behavior because setting a field not existing = defining an adhoc field.
$mapper->set('count_x',
'SELECT COUNT(id) from x where x.id = y.foreign_key group by x.id');
ref.: https://fatfreeframework.com/3.8/databases#VirtualFields
The way to fix this is to apply a whitelist of fillable fields that are allowed to be set in case you are using something like copyfrom.
i.e.:
$mapper->copyfrom('POST', function($val) {
return array_intersect_key($val, array_flip(['first_name', 'last_name', 'age']));
});
I have a table called user_wallet like this:
Then at the Controller, I tried this:
try {
if ($request->pay_wallet == '1') {
$us_id = Auth()->user()->usr_id;
$user_wallet = UserWallet::find('user_id', $us_id);
dd($user_wallet);
}
}catch (\Exception $e) {
dd($e);
}
But I get this error:
SQLSTATE[42S22]: Column not found: 1054 Unknown column '2' in 'field list' (SQL: select 2 from user_wallet where user_wallet.id = user_id limit 1)
However as you can see in the picture, there are two wallets with the user_id of 2.
So what's going wrong here? How can I solve this issue?
the find method only works on id so it's better to use where clause
$user_wallet = UserWallet::where('user_id', $us_id);
I think you are using find() wrong, this method accepts only one paramater, it is the value of the primary key you want to find. Because you are in a pivot table and there is no id present,
you will have to use firstWhere('user_id', $us_id) for the first occurrence or you will have to rewrite the find() method for the pivot table.
But please be aware that a user could have multiple wallets, so it might be better to ask them which wallet to use.
I am trying to figure out why is DB::raw() queries are getting sent as lowercases?
Query = DB::('table_name')->select(['is_read as isRead'])->get();
Result = [{ isRead: true }]
But when I do raw its converting it to lowercase
Query = DB::('table_name')->select(DB::raw('is_read as isRead'))->get();
Result = [{ isread: true }]
I have a reason to use DB raw so I really need to figure this thing out.
I'm not able to reproduce the issue you mention... Which version of Laravel are you using?
For instance, if I run the following:
DB::table('users')->select(DB::raw('is_read as isRead'))->get();
I would get the error:
Illuminate/Database/QueryException with message 'SQLSTATE[42S22]: Column not found: 1054 Unknown column 'is_read' in 'field list' (SQL: select is_read as isRead from users)'
Which is normal because I have no is_read column in my users table. However, you can see in the error that the isRead is not converted to lowercase.
Maybe you can use selectRaw instead:
DB::table('table_name')->selectRaw('is_read as isRead')->get();
The query would be:
select is_read as isRead from `table_name`
Otherwise, could you update your question to provide more information on how to reproduce so your issue with the capitalization.
I can confirm that when using DB:raw (or orderByRaw or any row raw methods) column names get converted to lowercase.
To avoid that, you can try to protect the name with quotes:
Query = DB::('table_name')->select(['is_read as "isRead"'])->get();
I am trying to calculate two columns values but I am receiving the following error. The Minus between invoice and payment is a arithmetical operation. Can you please help me.
Controller.php
public function getIndex( Request $request )
{
$this->data['balanceTotal'] = \DB::table('tb_accounts')->select('sum(invoice-payment)')->get();
return view('account.index',$this->data);
}
Index.blade.php
{{ $balanceTotal }}
Error
SQLSTATE[42S22]: Column not found: 1054 Unknown column
'sum(invoice-payment)' in 'field list' (SQL: select
sum(invoice-payment) from tb_accounts)
You need a raw expression:
\DB::table('tb_accounts')->select(\DB::raw('sum(invoice)'))
But, I suppose you need to sum invoice and payment:
\DB::table('tb_accounts')->select(\DB::raw('(invoice - payment) AS amount'))
See the docs: https://laravel.com/docs/5.5/queries#raw-expressions
Note: avoid the minus in your column name or use back-ticks (Do minus sign in mysql table column names cause issues?)
this will solve your problem
use Illuminate\Support\Facades\DB;
DB::table('tb_accounts')->select(\DB::raw('(invoice + payment) AS amount'))
You are getting this error
htmlentities() expects parameter 1 to be string, array given (View: /home/unive/public_html/sistem/resources/views/accounts/index.blade.php)
because you are passing array in place of string if you need to pass array in your view try to return like this
return view('account.index')->withdata($data);
and then use in your index.blade.php
$data['balanceTotal'];
I want to do a simple select with a SUM of several rows in Drupal, but I can't seem to figure out how to do that. I know there are more ways to do a query in Drupal (one of them is writing the actual query, but I don't want that).
Here is the code I have:
$query = db_select("node","n");
$query->fields("n", array("nid","likes" => "SUM(likes)"));
But apparently Drupal strips my brackets and I get the following error:
1054 Unknown column 'n.SUMlikes' in 'field list'
Could anyone help me? Is there something like $query->sum()?
You'd be best off using an expression:
$query = db_select('node', 'n')
->fields('n', array('nid'));
$query->addExpression('SUM(likes)', 'likes');
The first argument is the expression, the second the alias.
Hope that helps
