I am going to an informix 9.3 server and the following code works:

$ce_notes ="sfasdfasdfsadfsadfasdfasdf";
$sql = "insert into call_extension(ce_activity,ce_callresult,ce_notes) values (" . $ce_activity . ",3211664,?);";
   $stmt = odbc_prepare ($crs,$sql );
   $sqldata = array ($ce_notes);
   $r = odbc_execute ($stmt, $sqldata);

they following code fails:

$sql = "execute procedure web_cr_update(?,'ADD',1312,4748999,17057,'2001-09-25 15:34:16.000','2001-09-25 15:34:16',0,277,null,0,null,14999)";
   $stmt = odbc_prepare ($crs,$sql );
   $sqldata = array ($ce_notes);
   $r = odbc_execute ($stmt, $sqldata);

with the following error:

Warning: SQL error: [Informix][Informix ODBC Driver]SQL data type out of range., SQL state S1004 in SQLExecute in /home/httpd/html/followup/calladd.php on line 65

Note: The value in $ce_notes is the same in each case and the line number refers to odbc_execute line.

It also fails when I try:

$sql = "execute procedure web_filter_modify(?,14999,1312)";
....

Both stored procedures work within a c++ program.
