Drupal db_update not working, unless intentional error through batch API -

i'm submitting form view through drupal batch api update row in db. statement use is:

db_update('scores')     ->fields(['status' => 0])     ->condition('sid', $score->sid)     ->execute(); 

the batch returns , gives me feedback of

performed undo publishing on 1 item.

however, row in db not updated.

when using following code:

$result = db_update('scores')     ->fields(['status' => 0])     ->condition('sid', $score->sid)     ->execute();  drq($result); 

the batch api returns error due unexpected output, , after refreshing page manually, row in question is updated!

i can't life of me figure out what's going on nor how query batch api log somewhere can see what's going on.

any appreciated.

it seems there's 2 queries being executed. 1 db_update statement described earlier, , 1 entity.controller.inc::save() in entity module. latter started transaction negated db_update action.

i changed code following

db_update('scores')     ->fields(['status' => 0])     ->condition('sid', $score->sid)     ->execute();  $score->status = 0; $score->save(); 

and works intended. status of item gets changed in db , seems well. know ugly workaround actual problem, @ moment it's solution can find.
