i have a project to show database value...
but, the database name has dot in it.
my database name is "t.produk".
How can i select the database in laravel?
i run it and got an error says it invalid like below
EDIT:
and i also did it with just string, came out error too :
Here the picture
First of all - avoid naming database tables like that. You should not use any dots there. It could be t_produk as example.
But table name should be descriptive so go for something like products. Than name your entity as Product.
You get this error here because you can't set variable as (t.produk). You should pass a string as I see here. So do it like this:
protected $table = 't.produk';
EDIT:
I saw the error with a string variable. So now you see why the current table naming you choose is quite not good. DB reads it as follows:
select from database t table produk
If you will name your table like t_produk problem should be no longer here.
My bad, so the tables name can't have dot in it. noted.
Btw y'all thanks for the answers :)
before i use alias for table i get the error:
: Integrity constraint violation: 1052 Column 'id' in field list is ambiguous
Then i used aliases and i get this error:
unknown index a
I am trying to get a list of category name ( dependant to a translation) and the associated category id which is unique. Since i need to put them in a select, i see that i should use the lists.
$categorie= DB::table('cat as a')
->join('campo_cat as c','c.id_cat','=','a.id')
->join('campo as d','d.id','=','c.id_campo')
->join('cat_nome as nome','nome.id_cat','=','a.id')
->join('lingua','nome.id_lingua','=','lingua.id')
->where('lingua.lingua','=','it-IT')
->groupby('nome.nome')
->lists('nome.nome','a.id');
The best way to debug your query is to look at the raw query Laravel generates and trying to run this raw query in your favorite SQL tool (Navicat, MySQL cli tool...), so you can dump it to log using:
DB::listen(function($sql, $bindings, $time) {
Log::info($sql);
Log::info($bindings);
});
Doing that with yours I could see at least one problem:
->where('lingua.lingua','=','it-IT')
Must be changed to
->where('lingua.lingua','=',"'it-IT'")
As #jmail said, you didn't really describe the problem very well, just what you ended up doing to get around (part of) it. However, if I read your question right you're saying that originally you did it without all the aliases you got the 'ambiguous' error.
So let me explain that first: this would happen, because there are many parts of that query that use id rather than a qualified table`.`id.
if you think about it, without aliases you query looks a bit like this: SELECT * FROM `cat` JOIN `campo_cat` ON `id_cat` = `id` JOIN `campo` ON `id` = `id_campo`; and suddenly, MySQL doesn't know to which table all these id columns refer. So to get around that all you need to do is namespace your fields (i.e. use ... JOIN `campo` ON `campo`.`id` = `campo_cat`.`id_campo`...). In your case you've gone one step further and aliased your tables. This certianly makes the query a little simpler, though you don't need to actually do it.
So on to your next issue - this will be a Laravel error. And presumably happening because your key column from lists($valueColumn, $keyColumn) isn't found in the results. This is because you're referring to the cat.id column (okay in your aliased case a.id) in part of the code that's no longer in MySQL - the lists() method is actually run in PHP after Laravel gets the results from the database. As such, there's no such column called a.id. It's likely it'll be called id, but because you don't request it specifically, you may find that the ambiguous issue is back. My suggestion would be to select it specifically and alias the column. Try something like the below:
$categories = DB::table('cat as a')
->join('campo_cat as c','c.id_cat','=','a.id')
->join('campo as d','d.id','=','c.id_campo')
->join('cat_nome as nome','nome.id_cat','=','a.id')
->join('lingua','nome.id_lingua','=','lingua.id')
->where('lingua.lingua','=','it-IT')
->groupby('nome.nome')
->select('nome.nome as nome_nome','a.id as a_id') // here we alias `.id as a_id
->lists('nome_nome','a_id'); // here we refer to the actual columns
It may not work perfectly (I don't use ->select() so don't know whether you pass an array or multiple parameters, also you may need DB::raw() wrapping each one in order to do the aliasing) but hopefully you get my meaning and can get it working.
You might read this question every day so i tried another Stackoverflow's answer before asking:
CakePHP table is missing even when it exists
Anyways. The table i try to select data from does exist (quadra-checked uppercase/lowercase!) and it gets also listed via $db->->listSources().
Here's a screenshot of the query, the message and the last result from listing all Datasource's tables:
http://i.stack.imgur.com/CdhcV.png
Note: If i run this query in PHPMyAdmin manually it works fine. I would say its impossible to get the pictures output at one time in a view - now its up to you to tell me the opposite. By the way: I am pretty sure to use the correct Datasource.
I should tell additionally that the mysql-server is hosted on another platform. Since i can use it for my localhost-phpmyadmin if i modify the config.inc.php i can promise it is no Firewall-Problem.
Written in behalf of xcy7e:
The mistake was to execute the Query from the local Model. Here's the code:
$conn = ConnectionManager::getDataSource('myDB');
$conn->query($query);
// instead of $this->query($query);
In my Rails testing environment, I have a user_id that looks like 1234-567abc89. I'm getting inconsistent behaviour by querying this user in different tables. Most of the queries are working, but running one particular query fails:
ActiveRecord::StatementInvalid (Mysql::Error: Unknown column '1234' in
'where clause': SELECT * FROM `point_allocations` WHERE (user_id = 1234-567abc89) ):
So for some reason, everything beyond the hyphen is getting cut off. I realized that for the queries that work, it is looking up user 1234 instead of 1234-567abc89, but if all the others work, any idea why only this one would return an error?
You need to include quotations.
SELECT * FROM `point_allocations` WHERE (user_id = '1234-567abc89')
Because the user_id column expects character-typed data, it will take your value (1234-567abc89) and parse it as an integer, truncating the content after the hyphen. If you include it in quotations, it will accept it as a string and transfer properly.
Enjoy and good luck!
I'm trying to create a text file that contains the value of a custom field I added on redmine. I tried to get it from an SQL query in the create method of the project_controller.rb (at line 80 on redmine 1.2.0) as follows :
sql = Mysql.new('localhost','root','pass','bitnami_redmine')
rq = sql.query("SELECT value
FROM custom_values
INNER JOIN projects
ON custom_values.customized_id=projects.id
WHERE custom_values.custom_field_id=7
AND projects.name='#{#project.name}'")
rq.each_hash { |h|
File.open('pleasework.txt', 'w') { |myfile|
myfile.write(h['value'])
}
}
sql.close
This works fine if I test it in a separate file (with an existing project name instead of #project.name) so it may be a syntax issue but I can't find what it is. I'd also be glad to hear any other solution to get that value.
Thanks !
(there's a very similar post here but none of the solutions actually worked)
First, you could use Project.connection.query instead of your own Mysql instance. Second, I would try to log the SQL RAILS_DEFAULT_LOGGER.info "SELECT ..." and check if it's ok... And the third, I would use identifier instead of name.
I ended up simply using params["project"]["custom_field_values"]["x"] where x is the custom field's id. I still don't know why the sql query didn't work but well, this is much simpler and faster.
