Missing insert () method in Doctrine DBAL Query Builder

I feel like I have a moment where I miss something small here; I am having trouble using a method insert()

in a component QueryBuilder

in Dotrine DBAL 2.2.x / 2.3.x.

I did some investigation and here's a snippet from the QueryBuilder page from the DBAL documentation

\ Doctrine \ DBAL \ Query \ QueryBuilder supports creating SELECT, INSERT, UPDATE and DELETE queries. What type of query you build depends on the methods you are using.

Next, we explain some code examples I can just do:

$builder = $connection->createQueryBuilder();
$result = $builder
    ->insert('table_name')
    // ...

      

        
        
        
      

    

To use Query Builder in insert mode . Except when I do this, I get a complaint from PHP:

Fatal error : Call to undefined Doctrine \ DBAL \ Query \ QueryBuilder :: insert () method

Further verification QueryBuilder.php source code

I don't see any reference to any method insert(...)

, no class inherits from it, no traits added to QueryBuilder

that the insertion mechanism can open. Also, I can see this right at the top:

/* The query types. */
const SELECT = 0;
const DELETE = 1;
const UPDATE = 2;

      

        
        
        
      

    

No insert request type; however this interesting method comment for execute()

:

/**
 * Execute this query using the bound parameters and their types.
 *
 * Uses {@see Connection::executeQuery} for select statements and {@see Connection::executeUpdate}
 * for insert, update and delete statements.
 *
 * @return mixed
 */

      

        
        
        
      

    

Bottom line:

This is a large-scale project with the participation of 100 maintainers, I am more likely to find my interpretation here than aversion to something so fundamental because of the numerous versions, but I cannot understand for life what I am missing, Please help me to see the obvious.
