odbc_autocommit

(PHP 4, PHP 5, PHP 7, PHP 8)

odbc_autocommit — Toggle autocommit behaviour

说明

odbc_autocommit(resource $odbc, bool $enable = false): int|bool

Toggles autocommit behaviour.

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

参数

odbc: ODBC 连接标识符，详见 odbc_connect()。
enable: If enable is true, auto-commit is enabled, if it is false auto-commit is disabled.

返回值

Without the enable parameter, this function returns auto-commit status for odbc. Non-zero is returned if auto-commit is on, 0 if it is off, or false if an error occurs.

If enable is set, this function returns true on success and false on failure.

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.

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.

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.

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

Example: set autocommit on

<?php

   $Link_ID = odbc_connect("DSN", "user", "pass");

    $Return = odbc_autocommit($Link_ID, FALSE);

?>
