Wrapped fieldname to solve SQL Error when sorting

[jeroendeleur]

Wrapped fieldname with backticks, because when the primary key of a model is a reserved word, MySql will throw an error.

Description

When the model has a reserved word as the PK e.g. key sorting records will throw the following SQL error.

SQLSTATE[42000]: Syntax error or access violation: 1064 You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near 'key = 'cZKBUpPyUR' then 1 when key = 'EQ5zh0Eqhf' then 2 when key = 'lwmhTQ8C...' at line 1 (Connection: mysql, SQL: update age_groups set sort = case when key = 'cZKBUpPyUR' then 1 when key = 'EQ5zh0Eqhf' then 2 when key = 'lwmhTQ8Cjd' then 3 when key = '0XaE8LzBZN' then 4 when key = 'tUkKkfH3P2' then 5 when key

I've added backticks around $modelKeyName on line 47 of the CanReorderRecords concern, this will solve the issue.

I think this will break every other driver apart from MySQL? right?

This is a fair point. Is it an idea to replace it with upsert?

Replacing

$model
    ->newModelQuery()
    ->whereIn($modelKeyName, array_values($order))
    ->update([
        $orderColumn => DB::raw(
            'case ' . collect($order)
                ->map(fn ($recordKey, int $recordIndex): string => 'when `' . $modelKeyName . '` = ' . DB::getPdo()->quote($recordKey) . ' then ' . ($recordIndex + 1))
                ->implode(' ') . ' end'
        ),
    ]);

with

$collection = collect($order)
                ->map(fn ($recordKey, int $recordIndex) => [$modelKeyName => $recordKey, $orderColumn => $recordIndex]);
$model->upsert($collection->toArray(), [$modelKeyName], [$orderColumn]);

Hmm I'm not sure I've seen upsert used in this way. Maybe get the query grammar object, and then use invade($grammar)->wrapValue($string) to wrap the string in the correct quotes for that database engine?

[jeroendeleur]

That was my first aproach, but google sent me through the doctrine/dbal rabbit hole. I have changed the code to:

$wrappedModelKeyName = DB::connection()->getSchemaGrammar()->wrap($modelKeyName);

And then used the new variable in the raw SQL.

I have tested it on, MySql, MariaDB, SQLite and Postgres drivers, not on SQL server as I don't have a test bench for that.

Thanks for fixing it!
