New To Yii And 2 Mysql Questions

Hello all - total noob to yii

have not a clue where to place mysql code to attempt this using Active Record

currently have written raw mysql/php report generator for static pages that
generates google visualization bar-format charts that widgets consume,
but before attempting to convert to AR was wondering are the following doable

case 1: Automation
need to run 2 similar mysql queries

/*  get external inbound calls
example of output of query which is consumed by barFormat chart 
google barFomat gridchart along with get outbound calls
['<==outbound - inbound==>',11,'dur','avg'],
['816 ==> Kansas City, MO',11,'00:01:39','00:00:09'],
['812 ==> Evansville, IN',2,'00:01:18','00:00:39'],
...
*/
SELECT concat("['",
			case 
			   when length(src) = 10 then left(src,3) 
			   when length(src) = 11 then mid(src,2,3) 
			end,  
			" ==> ",
			concat(t2.city, ", ",t2.st),
			"',",
			count(src),
			",'",
			SEC_TO_TIME(sum(duration)),
			"','",
			SEC_TO_TIME(avg(duration)),
			"'],") as areacodes
FROM `cdr8`
join ac as t2
 	on  t2.acs = 
			 case 
			   when length(src) = 10 then left(src,3) 
			   when length(src) = 11 then mid(src,2,3) 
			 end  
WHERE length(src) > 9 
group by  
	case 
	   when length(src) = 10 then left(src,3) 
	   when length(src) = 11 then mid(src,2,3) 
	end

results then will be consumed by widget that displays google visualization barFormat grid
i'm running this offline and cut'n'paste (8 different tables 2 queries each table ).

case 2: Forensic filters for tables with excess of 500,000 rows
while search generated by gii crud admin and extended filtering for range is somewhat helpful need real WHERE clause. User needs to supply ranges as well as NOT ranges and dates and field lengths to test after render

WHERE
field2 BETWEEN '8000' AND '8100' 
AND field2 REGEXP '^-?[0-9]+$'
AND LENGTH(field2) = 4
AND ((LENGTH(field4) != 4 
AND  field4 NOT BETWEEN '8000' AND '8100')
OR (field4 REGEXP '^-?[0-9]+$'
AND LENGTH(field4) > 6)) 
AND LEFT(field0,11) between '2012-12-10' and '2012-12-13' 

Hope i've explain this enough for a response, even if it is run-away and stick to straight SQL queries and forget AR/yii entirely

Sorry for long post, but could not find any post that even reference BETWEEN a and b ranges or more complex searches.
Thanks
