To use in Eloquent  Add on top of your model  protected  table    table name as alias        table name should be exact as in your database     then use in your query like  ModelName  query  - gt select alias id  alias name

You can use less code  writing this        users   DB  table  really long table name          - gt get array  really long table name field very long name as short name       And of course if you want to select more fields  just write a     and add more     users   DB  table  really long table name          - gt get array  really long table name field very long name as short name    really long table name another field as other    and another       This is very practical when you use a joins complex query

To use aliases on eloquent models modify your code like this   Item       from   items as items alias        - gt join   attachments as att   DB  raw   att item id          DB  raw   items alias id          - gt select  DB  raw   items alias            - gt get      This will automatically add table prefix to table names and returns an instance of Items model  not a bare query result  Adding DB  raw prevents laravel from adding table prefixes to aliases
