Laravel数据库过滤器总数大于n

Question

How can I filter out only results when total is greater than n? other words only IPs with more wisits than n (say 500)

I tried ->where('total','>',500) but it didn't work

Thank you

$visits = DB::table('visits')
    ->select('ip_address',DB::raw('count(*) as total'))
    ->where('timestamp', '>=',\Carbon\Carbon::now()->startOfDay())
    ->groupBy('ip_address')
    ->orderBy('total', 'desc')
    ->get();

Answer 1

WHERE cannot be used on grouped item (such as count(*)) whereas HAVING can. You can refer WHERE vs HAVING question to understand more details,

You have to use having

->having('total', '>', 100)

optionally in your case you can use havingRaw

->havingRaw('count(*) > 2500')
->havingRaw('total > 2500')
