I have two different tables in sql server database on the same host that I need to join together in a query.
I would like to use the laravel QueryBuilder to do so.
I've tried so far:
return DB::table('users')
->select([
'users.id',
'Resources.FirstName'
])
->join('Resources.dbo.ID', 'Resources.UserID', '=', 'users.id');
It results in the following error: General error: 1 near ".": syntax error (SQL: select "users"."id", "Resources"."FirstName" from "users" inner join "Resources"."dbo"."ID" on "Resources"."ID" = "users"."id")
If I copy the query in my dabatase script editor and run it, it runs correctly and give the expected result.
I have also tried this
return DB::table('users')
->select([
'users.id',
'Resources.FirstName'
])
->join(DB::raw('Resources.dbo.ID'), 'Resources.UserID', '=', 'users.id');
return DB::table('users')
->select([
'users.id',
'Resources.FirstName'
])
->join(DB::raw('Resources.ID'), 'Resources.UserID', '=', 'users.id');
->join('Resources', function($q) {
$q->connection('tcollect')->on('Resources.ID', '=', 'users.id');
});
Is there a way to achieve this?
Please try that
DB::table('Database1.Resources as dt1')-> join('Database2.users as dt2', 'dt2.id', '=', 'dt1.UserID')->select(['dt1.*','dt2.*'])->get();

I use Alias name of column because I have two columns in different tables with the same name, when retrieve them one column will override another column
DB::table('trip_user')
->join('trips', 'trips.id', '=', 'trip_id')
->join('users', 'users.id', '=', 'user_id')
->where('guide_id','=',$id)
->get(['*','trips.name As tirp_name','trip_user.id As reservation_id'])
How can I write it with paginate?
Try it this way:
$result = DB::table('trip_user')
->join('trips', 'trips.id', '=', 'trip_id')
->join('users', 'users.id', '=', 'user_id')
->where('guide_id','=',$id)
->paginate(100, ['*','trips.name As tirp_name','trip_user.id As reservation_id']);
I'm trying to get my query working and I'm hoping someone can check out my code to see where I'm going wrong.
What happens is that I get This page isn't working page and I don't get any errors in my log file or dev tools
Here is my query
$query = DB::connection('data')
->table('products')
->leftJoin('categories', 'products.product_id', '=', 'categories.product_id')
->leftJoin('users', 'products.product_id', '=', 'users.product_id')
->select('products.product_id', 'categories.name', 'users.name')
->where('products.product_id', '=', 134)
->get();
I think your mistake is in select you are trying to get name from 2 table try this
$query = DB::connection('data')
->table('products')
->leftJoin('categories', 'products.product_id', '=', 'categories.product_id')
->leftJoin('users', 'products.product_id', '=', 'users.product_id')
->select('products.product_id', 'categories.name as category_name', 'users.name')
->where('products.product_id', '=', 134)
->get();
I noticed that when you join tables in laravel using lefJoin() or Join the ids that it returns are the one of the last table. So I was wondering if I can join two tables in laravel and keepig the ids of the first table?
Here's my query
$comments = DB::table('posts')
->where('posts.parent_id',$id)
->leftJoin('profiles', 'profiles.user_id', '=', 'posts.user_id')
->leftJoin('users', 'users.id', '=', 'posts.user_id')
->get();
you should show ur code .
but try like this
$query = Users::where("users.user_id","=",$users->user_id)
if ($request->exists('product_name')) {
$query->join('products', 'users.user_id', 'products.user_id');
$query->where('products.product_name', 'like', '%' . $request->input('product_name')
. '%');
}
$test= $query->get();
Better use aliases in this case.For Example
DB::table('table_1')->select('table1.column_name as alias_name', 'table_2.column_name as alias_name2')->leftjoin('table_2', 'table_2.userId', '=', 'table_1.id')
->get();
You can select all from first table and nothing from second
DB::table('table_1')->join('table_2', 'table_1.id', '=', 'table_2.table_1_id')
->selectRaw('table_1.*')
->get();
Example DB::table('guests')->join('answers', 'guests.id', '=', 'answers.guest_id')
->selectRaw('guests.*')->get()
You also can select here anything from another table
use: ->addSelect('table_2.column')
I have a posts table that has join query with 4 other tables. 3 of them are one to one relations but the 4th is one to many. I want the query to return only 1 row for each post. What i am trying so far is like this-
$query = DB::table('posts')
->select('posts.*',
'subcategories.subcategory_title_en',
'subcategories.subcategory_title_bn',
'categories.category_title_en',
'categories.category_title_bn',
'users.*',
'postimages.postimage_thumbnail'
)
->join('subcategories', 'subcategories.subcategory_id', '=', 'posts.subcategory_id')
->join('categories', 'categories.category_id', '=', 'subcategories.parent_category_id')
->join('users', 'users.id', '=', 'posts.user_id')
->join('postimages', 'postimages.post_id', '=', 'posts.post_id');
$query->groupBy('posts.post_id');
echo $query->count();
exit();
I have currently 50 posts in database, but the query returns all rows for each postimages, more than 1 row for each post that is. I thought distinct would only show each post_id once? What am i missing here?
I would prefer if someone tells me how to do this with query builder. As this will have a lot of searching on different columns and i want it to be as fast as possible.
This is a simpler version -
$query = DB::table('posts')
->select('posts.*','postimages.postimage_thumbnail')
->join('postimages', 'postimages.post_id', '=', 'posts.post_id')
->groupBy('posts.post_id');
echo $query->count();
exit();
The strange thing is the SQL query that is shown by laravel " select posts.*, postimages.postimage_thumbnail from posts inner join postimages on postimages.post_id = posts.post_id group by posts.post_id" works fine in mysql
You should use groupby
Try this code
$query = DB::table('posts')
->select('posts.*',
'subcategories.subcategory_title_en',
'subcategories.subcategory_title_bn',
'categories.category_title_en',
'categories.category_title_bn',
'users.*',
'postimages.postimage_thumbnail'
)
->join('subcategories', 'subcategories.subcategory_id', '=', 'posts.subcategory_id')
->join('categories', 'categories.category_id', '=', 'subcategories.parent_category_id')
->join('users', 'users.id', '=', 'posts.user_id')
->join('postimages', 'postimages.post_id', '=', 'posts.post_id')->groupBy('posts.post_id');
In config/database.php at "mysql" change : 'strict' => true, to false
Here I joined 2 tables addprojects and users. But It show me error. How can I fix it?
$test= addproject::select('addprojects.id','addprojects.proj_name',DB::raw("DATEDIFF(addprojects.proj_starts,addprojects.proj_end)AS Days"))
->join('user', 'users.emp_id', '=', 'addprojects.emp_id')
->where('id', 1)->get();
what the error appeared to you ?
check this example below, i had done it to join tables :
$nextvisits = patients::join('visits', 'visits.patient_id', '=', 'patients.id')
->join('users', 'users.id', '=', 'visits.user_id')
->where('visits.revisit_date','>=',$now_str)
->where('patients.clinic_id', $user->clinic_id)
->where('visits.clinic_id', $user->clinic_id)
->where('visits.active','=','1')
->get();
