Answer 1

insert_batch translations into a SQL query that uses the VALUES form of INSERT . This requires every item being inserted to specify the same fields.

Answer 2

I have fixed my issue after change the line of code in the file "system\\database\\DB_query_builder.php"

Replace the code in the the file DB_query_builder.php, Path : "system\\database\\DB_query_builder.php"

protected function _insert_batch($table, $keys, $values)
{
return 'INSERT INTO '.$table.' ('.implode(', ', $keys).') VALUES '.implode(', ', $values);
}

By below code

protected function _insert_batch($table, $keys, $values)
{
if(is_array($values))
{
$values = implode(',',$values);
}
return 'INSERT INTO '.$table.' ('.implode(', ', $keys).') VALUES '.implode(', ', $values);
}

I have resolved my issue by this way. hope, same will work for you.
