Description:
------------
When using the oracle-supplied ODBC Driver under Linux, any odbc_exec() call fails with:
[unixODBC][Driver Manager]Driver does not support this function
The log files is a bit more verbose:
[unixODBC][Driver Manager]Driver does not support this function, SQL state IM001 in SQLSetStmtOption
The offending code is in odbc_prepare(line 875) and odbc_exec (line 1276), when the module tries to set SQL_CURSOR_DYNAMIC via SQLSetStmtOption, which returns an error using the oracle driver.
The error goes away if I undefine HAVE_SQL_EXTENDED_FETCH, so the statements will not be reached.
Would it be possible to only issue a notice when this command fails and proceed with processing.
I can provide a patch to fix it, if that's appreciated.
Reproduce code:
---------------
$dsn="ANY_ORACLE_DSN";
$uid="ANY_VALID_USERID";
$pwd="ANY_VALID_PASSWORD";
$conn = odbc_connect ( $dsn, $uid, $pwd );
/* The connect succeeds */
if (!$conn) {
printf("Error connecting to $database.<br>\n");
return;
}
/* The exec will fail with the decribed error */
$cursor = odbc_exec($conn,"SELECT tname from tab");
if (!$cursor) {
printf("Failure in odbc_exe:<br>\n");
printf("%s<br>\n",htmlentities(odbc_errormsg($conn)));
return;
}
Actual result:
--------------
[unixODBC][Driver Manager]Driver does not support this function, SQL state IM001 in SQLSetStmtOption

Well, here is a patch. I dont know whether the formatting is preserved her properly, it should apply cleanly with "patch -p1 < patchfile" from whithing the php-5.0.5 directory. The patch just stops odbc_exec and odbc_prepare from failing if the SQLSetStmtOption fails. The warning is still displayed in the error_log. It would be great if this could be applied.
