PHP: odbc_autocommit

Description

mixed odbc_autocommit ( resource connection_id [, bool OnOff] )

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 TRUE, auto-commit is enabled, if it is FALSE auto-commit is disabled. Returns TRUE on success, FALSE on failure.

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

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.

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

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.
