Update Table without loops - laravel

Question

There is a table foo and it has a column called fooPos. I ned to update the fooPos column with respect to id.
I have the following data
$id = [21,23,34,56,76];
$fooPos = [1,2,3,4,5];
How can I update this without using loops?
It's like 21(id) => 1(fooPos), 23 => 2, 34 =>3 etc.,

Answer 1

You have a solution with INSERT INTO ... ON DUPLICATE KEY UPDATE..., more details in here Multiple update
That solution can trigger an error if the ID doesn't exist and you have some other required fields. In that cas you ca use this solution:
$updateSets = [];
$ids = [21,23,34,56,76];
$fooPos = [1,2,3,4,5];
foreach ($ids as $key => $id) {
$updateSets[] = 'SELECT '.$id.' as set_id, '.$fooPos[$key].' as pos ';
}
$updateSetsString = implode(' UNION ALL ', $updateSets);
\DB::statement('UPDATE your_table JOIN ('.$updateSetsString.') up_set ON your_table.id = up_set.set_id SET your_table.pos = up_set.pos');

function updateTableWithoutQueryLoops()
{
try {
$id = collect([21,23,34,56,76]);
$fooPos = collect([1,2,3,4,5]);
// To check both parameters should have an equal number of elements.
if(count($id) == count($fooPos) ) {
$combinedValues = $id->combine($fooPos);
} else {
return 'Please check equal number of elements for give arrays.';
}
// Run foreach loop of Combined values
foreach ($combinedValues as $id => $fooPos) {
$id = (int) $id;
$cases[] = "WHEN {$id} then ?";
$params[] = $fooPos;
$ids[] = $id;
}
$ids = implode(',', $ids);
$cases = implode(' ', $cases);
$params[] = \Carbon\Carbon::now();
return \DB::update("UPDATE `foo` SET `fooPos` = CASE `id` {$cases} END, `updated_at` = ? WHERE `id` in ({$ids})", $params);
} catch (\Exception $e) {
return 'Exception message:' . $e->getMessage() . ' with code: ' . $e->getCode();
}
