PHP回滚方法失败

Question

我已经尝试过这段代码，不幸的是回滚方法失败了！ 提前致谢！！

$bash = new mysqli('localhost', 'root', '','dbastegoi');
$bash->autocommit(FALSE);

echo 'timologio';
$r =$bash->query("INSERT INTO tbparastatika (strArithmos, fkERGO, strPROMITH, sngCOST, intTYPOS, intDRASH) VALUES ('1','1001','123123123',800138,1,1)");
//ΕΙΣΑΓΩΓΗ ΤΙΜΟΛΟΓΙΟΥ
 $i = $bash->insert_id;
ECHO PHP_EOL;
echo 'dapanh';
try {
    $r =$bash->query("INSERT INTO tbdapanes_stegash (idPARASTATnIKO, sngCOST, fkDIAMERISMA, intMONTH) VALUES ($i,100,1,1)");
    echo $r;
} catch (Exception $e) {
    echo 'error2';
}

$bash->commit();
$bash->rollback();

//$SYNDESH->commit();
//$SYNDESH->rollback();
$bash->close();

您不能先提交，然后再进行回滚。如果您的查询运行没有错误，则必须提交，如果遇到错误，则必须回滚：

try {
    $r =$bash->query("INSERT INTO tbdapanes_stegash (idPARASTATnIKO, sngCOST, fkDIAMERISMA, intMONTH) VALUES ($i,100,1,1)");
    echo $r;
    $bash->commit();
} catch (Exception $e) {
    echo 'error2';
    $bash->rollback();
}
