ActiveRecord & oci8 driver adding double quotes to table names and fields

[eluser]Andre83[/eluser]
I've just noticed that using ActiveRecord and the oci8 driver, writing this piece of code

Code:

$this->db->get('mytable')

produces the statement

Code:

SELECT * FROM "mytable"

, that fails miserably when executed.

This happens because the

Code:

$_escape_char

variable at line 49 of oci8_driver.php equals

Code:

"

Setting it to an empty string solves the problem; but is this really a possibile solution, or can it be done differently without having to patch the driver?
