 The query builder is used for regular CRUD operations on the database.
 
-#### Prefix
-
-Projects often use a prefix for all of the tables. For this project the default prefix is `oms_`.
-
-```php
-$query = new Builder();
-$query->prefix('oms_');

 #### Select, Insert, Update, Delete
 
 Both `select` and `insert` expect the column names as parameter. The `where`, `from` and `into` clause can be necessary depending on the type of operation like a normal sql query.
 
 ```php
-$query->prefix(...)->select('columnA', 'columnB')->from('table')->where(...);
-$query->prefix(...)->insert('columnA', 'columnB')->values('a', 'b')->into('table');
+$query->select('columnA', 'columnB')->from('table')->where(...);
+$query->insert('columnA', 'columnB')->values('a', 'b')->into('table');
 ```
 
 The `update` expects the table name which should be updated and then the `set` function to define the columns and new values.
 
 ```php
-$query->prefix(...)->update('table')->set(['columnA' => 'a'])->set(['columnB' => 'b'])->where(...);
+$query->update('table')->set(['columnA' => 'a'])->set(['columnB' => 'b'])->where(...);
 ```
 
 The `delete` function only expects the `from` and `where` clause to identify the to delete columns in a table.
 
 ```php
-$query->prefix(...)->delete()->from('table')->where(...);
+$query->delete()->from('table')->where(...);
