Answer 1

Use MySQL functions STR_TO_DATE and CONCAT to put your month and year fields together as a date. http://dev.mysql.com/doc/refman/5.0/en/date-and-time-functions.html#function_str-to-date http://dev.mysql.com/doc/refman/5.1/en/string-functions.html#function_concat

select Amount
from tbl1
where STR_TO_DATE(CONCAT(tbl1.Entered-month,'-',tbl1.Entered-year),'%m-%Y') >= [start date] 
    and STR_TO_DATE(CONCAT(tbl1.Entered-month,'-',tbl1.Entered-year),'%m-%Y') <= [end date]

OR

select Amount
from tbl1
where STR_TO_DATE(CONCAT(tbl1.Entered-month,'-',tbl1.Entered-year),'%m-%Y') 
    between [start date] and [end date]

Make sure [start date] and [end date] are in the correct date format when passed into the query. Use STR_TO_DATE on those parameters if they are string parameters.

select Amount
from tbl1
where STR_TO_DATE(CONCAT(tbl1.Entered-month,'-',tbl1.Entered-year),'%m-%Y') 
    between STR_TO_DATE(startDate,'%Y-%m-%d') and STR_TO_DATE(endDate,'%Y-%m-%d')
