ODBC Functions
If you are using persistent connections (odbc_pconnect rather than odbc_connect) the next script that reuses the connection will inherit your changes to autocommit.
odbc_autocommit
(PHP 4, PHP 5)
odbc_autocommit — Toggle autocommit behaviour
Description
Toggles autocommit behaviour.
By default, auto-commit is on for a connection. Disabling auto-commit is equivalent with starting a transaction.
Parameters
-
connection_id -
The ODBC connection identifier, see odbc_connect() for details.
-
OnOff -
If
OnOffisTRUE, auto-commit is enabled, if it isFALSEauto-commit is disabled.
Return Values
Without the OnOff parameter, this function returns
auto-commit status for connection_id. Non-zero is
returned if auto-commit is on, 0 if it is off, or FALSE if an error
occurs.
If OnOff is set, this function returns TRUE on
success and FALSE on failure.

Hi (i'm belgian then sorry for my english).
I think you can do more simple to check the errors :
$conn = odbc_connect($odbc,$user,$password)
or die($error);
odbc_autocommit($conn, FALSE);
odbc_exec($conn, $query1);
odbc_exec($conn, $query2);
if (!odbc_error())
odbc_commit($conn);
else
odbc_rollback($conn);
odbc_close($conn);
I'm not sure it's better to use odbc_error() than
odbc_error($conn). It seems to be the same result.

It seems that example made by andrea dot galli at acotel dot com works exactly the contrary.
It sets autocommit OFF and NOT ON like it's written inside note!

If a transaction is started (autocommit disabled) while there is an active result id on the connection, odbc_autocommit will post a warning (Cannot set autocommit). Use odbc_free_result to clear the result id's or start the transaction before you execute the SQL.

Example: set autocommit on
<?php
$Link_ID = odbc_connect("DSN", "user", "pass");
$Return = odbc_autocommit($Link_ID, FALSE);
?>

When used in a odbc_fetch loop your selected resultset is lost and loop ends.

using autocommit functionality to rollback transactions in a "workspace"
<?php
$conn = odbc_connection("$DSN","USER","PASS");
//turns off autocommit
odbc_autocommit($conn,FALSE);
$query1 = "some SQL";
$query2 = "some more SQL";
$ErrorCount = 0;
//if odbc_exec fails it will increment the $ErrorCount
$result = odbc_exec($conn,$query1) or $ErrorCount++;
$result2 = odbc_exec($conn,$query2) or $ErrorCount++;
//checking for errors, commit if none, rollback else
if ($Errorcount == 0){
odbc_commit($conn);
echo "transaction successful";
}
else{
odbc_rollback($conn);
echo "there were errors processing the transaction.
No changes were made to the database";
}
odbc_close($conn);
?>
Cheers,
Ron
