The code polishing

[sleptor]

Let's make the code more beautiful and compact :)

1. You extended \yii\db\Command. It is ok. But you copy-pasted a lot of unnecessary code from a parent class to your child class. You should clean it up.

for example, properties
public $db;
public $params = [];
...
and so on
must be removed from your class
some unnecessary methods should be removed as well

I checked only Command class, but I guess other classes may be affected as well.
Please fix it.

2. https://github.com/sanchezzzhak/kak-clickhouse/blob/master/Command.php#L332
   I guess preg_match may be replaced with stripos here

3. to be continued :)

I guess a lot of methods of Command class can be removed as well
cache
noCache
getSql
setSql (why did you change it?)
queryAll
queryOne
bindValues (why schema checking was commented out? you set $typeMap in Scheme class, all has to work good)

maybe some other methods may be removed also..

the main idea is the MOST methods MUST be inherited from a parent class

$_sql & $_pendingParams must be removed as well

setSql (why did you change it?)

I do not remember (((

getSql, setSql, queryAll, queryOne - removed
