Try:

strQuery = "
	SELECT SUM(`Production`) 
	FROM` MONTHLYPROD` 
	WHERE	(STR_TO_DATE(`DATE`,'%m/%d/%Y') 
				BETWEEN 
						STR_TO_DATE('01/12/1999','%m/%d/%Y') 
					AND 
						STR_TO_DATE('01,02,2000', '%m,%d,%Y') 
			) 
		AND (`UNIQUEID` LIKE '"+engineName+"')";

uh oh, it's not working :(
am i doing any wrong?
i am using visual studio 2008 with ms.access as the data source

and the error is :

An unhandled exception of type 'System.Data.OleDb.OleDbException' occurred in System.Data.dll

Additional information: Undefined function 'STR_TO_DATE' in expression.

You posted this in MySQL. The syntax I gave you is for MySQL, NOT access.
Try:

strQuery = "
	SELECT SUM([Production]) as total
	FROM [MONTHLYPROD] 
	WHERE( 
			CDATE([DATE])
				BETWEEN 
						#01/12/1999# 
					AND 
						#01/02/2000# 
		) 
		AND ([UNIQUEID] LIKE '"+engineName+"')"
