I have one Table called Draft which has several fields that user will select like PlayerID ,DraftTeam and Ncca Team then I have 4 remaining textboxes and here is where I don't know where to start I have a  sub that gets current year 2014 but when user goes to use this it will be 2015 so I made that field available for testing now I have 3 textboxes left one is round, one is Draft position and last is overall position at the round only increases in NFL after 32 draft positions have been reached 30 for NBA and 30 for nhl overall just increments until the end so after round 1 has been complete then round becomes 2 and Draft position goes back to 1 and based on sport increments to either 32 NFL 30 NBA AND 30 NHL. THE Issue is if any of these 3 sports adds a new team to their league. That will screw up flow cause if I hardcode 32,or 30. oh overall position is just a count which increments.
Any suggestions

I don't quite understand the question. Maybe examples might make it clearer.

Assuming that your problem is that you want the minimum number of matches than any team has played, and you have a Year field and a Team field, so you know that a particular team has played x matches in a particular year, then you could use:

Select min(Matches) as MinMatches
from 
(select [Year], Team, count(Team) as Matches
from Draft
where [Year] = (select max(Year) from Draft)
Group by [Year], Team) as t

Open in new window


However, as I said, what you are asking for is not clear. Maybe you could also post the structure of your tables.

Sorry Guys that I was unclear I posting to screenshots one shows a complete round 1 Draft and the 2nd round 2 draft You can see the draft position stays 1to32 and overall just keeps incrementing. Here 2 screen shots
I thing I was thinking of using something like this
 Dim sql As String = "SELECT TOP 1 draftpos FROM draft ORDER BY overallpos DESC" this won't work but I know this will grab last row I'm just trying to think the logic not a SQL Master wish I was.

Still not clear what you want.

If you want OverAllPos to be from 1-32, then use ROW_NUMBER().

if you look at both pics column Draftpos is the column 1-32 and look at overallpos it goes 1-32 but on 2nd round 33 to 64 that column keeps incrementing until the entire draft is done. next round Draftpos is 1-32 Each Nfl team gets a pick then it's 3rd round Draftpos 1-32 and then Overallpos is 65-100. I apologize if this is not clear. But that's what I am Tasked with.

Therefore, I would used ROW_NUMBER().

If you knew the number of teams, then I could use % as the modulo.

Do you want to grab all row or just one field?
For full row use this query:
"SELECT TOP 1 * FROM draft ORDER BY overallpos DESC"
