Laravel DB::update don't working, doing nothing at all, without any errors - sql

Question

I am learning how to run raw SQL queries and stuck at UPDATE operation.
I have route for INSERT:
Route::get('/insert', function (){
DB::insert('insert into posts (title, content) values (?, ?)', ['PHP with Laravel', 'Just testing']);
return 'after insert';
});
And route for SELECT:
Route::get('/read', function (){
$results = DB::select('select * from posts');
return var_dump($results);
});
After SELECT query I see:
/home/pavel/www_mysite/TestLaravel/routes/web.php:31:
array (size=1)
0 =>
object(stdClass)[239]
public 'id' => int 11
public 'title' => string 'PHP with Laravel' (length=16)
public 'content' => string 'Just testing' (length=12)
public 'created_at' => null
public 'updated_at' => null
public 'is_admin' => int 0
And at least UPDATE query:
Route::get('/update', function (){
DB::update('update posts set title = "Nothing here"');
});
After that query the new SELECT query shows the same data and in PHPPgAdmin I found no changes. I installed LaravelDebugBar and may see it at the bottom of the browser at pages for INSERT and SELECT queries, but don't see it at the page for UPDATE query. I cannot realize, where is the mistake.

Answer 1

try to use where clause.
example :
$affected = DB::update('update users set votes = 100 where name = ?', ['John']);

Answer 3

I run your update code on my local environment (laravel 5.2, mysql 5.1). It's updated OK.
How about your log?

Answer 4

After some extra research I found that PostrgreSQL may store case-sensitive names of tables and columns. For that case you need to take their names in double quotes in your query. I think that when PostrgreSQL found double quotes in the query - it "thinks" that it is table/column name. But there is no column with those name.
