odbc_execute doesn't work with variable parameter

[els_p]

when I execute these statements:

 

$road = 'A013';

$result = odbc_prepare($conn_id, "SELECT from, to FROM roads WHERE ident4 = ?");

odbc_execute($result, array($road));

 

I get this error message:

 

Warning: odbc_execute() [function.odbc-execute]: SQL error: , SQL state 00000 in SQLExecute in /var/www/html/rapportering/events/kiesweg2.php on line 24

 

when I use odbc_prepare without ? like this:

 

$result = odbc_prepare($conn_id, "SELECT from, to FROM roads WHERE ident4 = 'A013'");

odbc_execute($result);

 

It gives me the correct results.

 

How can I solve this?

 

I already tried to get more error info with

echo odbc_errormsg( $conn_id );

but this doesn't give me any extra info...

I just read this was a bug fixed in PHP 5.2.2.
