[DBAL-345] When inserting decimals into Oracle, getting ORA-01722: invalid number

Mon, 17 Sep 2012 10:23:27 +0000

When I insert decimals into database I get the following error message:

ORA-01722: invalid number

Oracle wants decimals (e.g. NUMBER(5,2)) separated by comma instead of a dot. I think the reason is that I use the german version of Windows. I tried to modify the following method of \Doctrine\DBAL\Driver\OCI8\OCI8Statement::bindValue() just for testing of course:

    public function bindValue($param, $value, $type = null)
    {
        if (is_float($value)) {
            $value = str_replace('.', ',', (string) $value); // <--
        }
        return $this->bindParam($param, $value, $type);
    }

With this modification I do not get the error anymore.
It would be great if a solution could be found. The strange thing is, if I query "SELECT * from nls_database_parameters where PARAMETER='NLS_NUMERIC_CHARACTERS'" I get ".," which means that a dot is already used as decimal separator. Maybe Oracle preferes the Locale of the OS?!
Maybe you could provide a setting which defines what separator should be used for decimals.

I found some Links that might be interesting regarding this issue:
