Here is my query to get a list of all groups for all months.  I have also attached the output in a file.  As you can see from the data results, the Month column presents a challenge.  I would like to find all records between the months of December to February. How could I do so in SQL?  I imagine that I will have to convert the Month column to a date type somehow.

select P.Agency, M.Month, F.Description,F.GrossAmount,F.NetAmount,F.InKindAmount from tblOrgProfile P 
Join tblorgMonthlyReport M on M.AgencyID = P.AgencyID
Join tblOrgMonthlyFunds F on F.MonthlyID = M.MonthlyID
Where Agency <> 'Administrator'
order by Agency

maybe this:

DATEPART(month, some_Date) in (12,1,2)

Honestly, I think it'd be more effort to force it to a date format than to just process it as is:

WHERE
    [Month] LIKE '%Dec%' OR
    [Month] LIKE '%Jan%' OR
    [Month] LIKE '%Feb%'

what values do you have? string like 'December', 'January', February'? Then:

month in ('December', 'January', February')

The problem is that from a vb6 form I am having a user choose from a date range and then I would retrieve it in SQL.

I would like to specify a date range which means the code would need to be more scalable for such a purpose.

Any other ideas?

The value would be a beginning month and an ending month.

For example

December to February

I would be passing only two variables: December, February

The attached file shows what I have in my table related to months.

... where
DATEPART (month, M.Month) between GetMonth(@param1)+12 and GetMonth(@param2)+12

where GetMonth is a function like

create function GetMonth(@s varchar) returns int32 as 
begin
	return (case @s 
		when 'January' then 1
		...
		when 'December' then 12
	end
	);
end;

maybe this (fix for above query where I used +12):

... where
(
(DATEPART (month, M.Month) >= GetMonth(@param1) and DATEPART (month, M.Month)<=GetMonth(@param2)) or
(DATEPART (month, M.Month) <= GetMonth(@param1) and DATEPART (month, M.Month)>=GetMonth(@param2))
)

I think the parenthesis are off.  I corrected here:

select P.Agency, M.Month, F.Description,F.GrossAmount,F.NetAmount,F.InKindAmount from tblOrgProfile P 
Join tblorgMonthlyReport M on M.AgencyID = P.AgencyID
Join tblOrgMonthlyFunds F on F.MonthlyID = M.MonthlyID
Where Agency <> 'Administrator' And
((DATEPART (month, M.Month) >= 7) and (DATEPART (month, M.Month) <= 12)) or
((DATEPART (month, M.Month) <= 7) and (DATEPART (month, M.Month) > 12))
order by Agency

The problem is that I get an error:

Msg 241, Level 16, State 1, Line 1
Conversion failed when converting date and/or time from character string.
