Hi, I am using PHP+ODBC+Oracle driver+instantclient to connect to Oracle database and I have problem with national characters in queries.

The database has charset EE8MSWIN1250 and I want to have the same charset on the client, so my NLS_LANG=".EE8MSWIN1250".

The data from the server are fetched right, the data in bind parameters (prepare/execute) are sent right, but the query itself is always sent as ISO-Latin1.

Example - this works fine:
$ret = odbc_prepare($dbh,"insert into TABLE1 values (?)");
odbc_execute($ret,array('ě'));

Example - this works but characters are broken:
odbc_exec($dbh,"insert into TABLE1 values ('ě')");

The problem is that the query itself is always treated as ISO-Latin1 and it does not follow the setting of NLS_LANG, it ignores it completely.

Is it an oracle bug? Is there any way around?

Ubuntu Server 6.06, PHP 5.2.3, unixODBC, instantclient-10.2.0.3, ODBC-Linux-10.2.0.3

I have checked the oci8 extension too, it works fine (charset is part of oci_connect call) but I cannot use it because it clashes with Gupta client for some reason.

Thank you.
