The following column Laravel Tutorial will introduce to you the "DB::Exception: Missing columns" problem caused by using clickhouse query in laravel. I hope it will be helpful to everyone!
Use clickhouse Special attention: you cannot write like this!
$where = [];
if($cookieId) {
$where['cookie_id'] = $cookieId;
}
if($host) {
$where['host'] = $host;
}
if($uri) {
$where['uri'] = $uri;
}
$builder = DB::connection('clickhouse')
->table((new AccessLogs)->getTable())
->where($where);
if(!empty($startTime)) {
$builder->where('create_time', '>=', $startTime);
}
if(!empty($endTime)) {
$builder->where('create_time', '<=', $endTime);
}When querying with multiple conditions, the $where array will be treated as a field in SQL, resulting in DB::Exception: Missing columns: '2022-09-27 13:00:49' '2022 -09-27 16:00:49' error while processing query.
Optimize like this:
$builder = DB::connection('clickhouse')
->table((new AccessLogs)->getTable());
if(!empty($cookieId)) {
$builder->where('cookie_id', $cookieId);
}
if(!empty($host)) {
$builder->where('host', $host);
}
if(!empty($uri)) {
$builder->where('uri', $uri);
}
if(!empty($startTime)) {
$builder->where('create_time', '>=', $startTime);
}
if(!empty($endTime)) {
$builder->where('create_time', '<=', $endTime);
}can query correctly.
One more thing to mention: when querying on the command line, use single quotes for parameter values. When using double quotes, the parameter value will also be treated as a field:
The correct operation is:
select * from access_log where create_time >= ‘2022-09-27 13:00:49’ and create_time <= ‘2022-09-27 16:00:49’ order by create_time desc limit 10;
