odbc_autocommit

(PHP 4, PHP 5)

odbc_autocommit — Toggle autocommit behaviour

Описание

mixed odbc_autocommit ( resource $connection_id [, bool $OnOff ] )

Toggles autocommit behaviour.

By default, auto-commit is on for a connection. Disabling auto-commit is equivalent with starting a transaction.

Список параметров

connection_id

The connection identifier.

OnOff

If OnOff is TRUE, auto-commit is enabled, if it is FALSE auto-commit is disabled.

Возвращаемые значения

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.

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

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.

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!

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.

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.
