Question

For inserting special characters in data like (,’)etc., I am using mysql_real_escape_string() function & it’s working fine.

Now I want to use same variable while inserting values in Oracle.

$str = 'N.G.Palace\'s Building',
    'xyzcity', '12345678','India','100001',12

Here $str is result of mysql_real_escape_string(). so it escapes special character.
Now my code for oracle is like this-:

 $qry ="INSERT INTO Ora_table(ship_to_street, ship_to_city,ship_to_country, ship_to_telephone, order_id, record_no) VALUES(".$str);

So my doubt is Oracle is not accepting values return by mysql_real_escape_string i.e. Palace\’s (like this as this mysql function attach \ before ‘single quote)?
So can anybody tell me ho9w can I use that variable $str to insert data into Oracle?

Also I tried like this also-:

"q"."'"."c".$str."c"."'"

can we use this for multiple values like in my case…though still I am unable
to inser data in oracle?

HOW to insert special characters in Oracle db?
like 'SWEET/HOME', 'CROY-BOY' etc. /,-,\ etc.

please tell me..

I strongly urge you not to build queries by appending strings together. This is a ticket straight to hell – or to SQL Injection City, which is one stop earlier. 🙂 Seriously, though, if you use parameter markers and bind the values to the parameter markers you gain a couple of advantages:

1. You don’t have to escape anything, and
2. No worries about SQL injection.

Share and enjoy.
