Real SQL scripting quandry linking data to 2 values on the same row

Real SQL scripting quandry linking data to 2 values on the same row

am 02.05.2005 22:58:31 von DFS

Hi All

Wonder if you could help me with the problem I've caused myself!!

I have 2 problems both exactly the same and I can't fathom how to get round
them.

PROBLEM 1 (I am using an Access 2000 DB):

I basically poke the codes of team names into a line-by-line history table
so I'm not storing redundant data (ie the long team names) on each row, but
now that I want to query this historic info and link/display the right names
I can't do it. My query is as follows:

select WEEK, HOMETEAMID, HOMETEAMSCORE, HOMETEAMSHOTS,
HOMETEAMSAVES, AWAYTEAMID, AWAYTEAMSCORE, AWAYTEAMSHOTS,
AWAYTEAMSAVES
from MATCHES
where MATCHID='1'

Above is all the fields in my MATCHES table and this query works fine, but
it shows the team ids/codes and I want to link in my TEAMS table so that the
HOMETEAMID and AWAYTEAMIDs are substituted for the actual team names, which
are in my TEAMS table. The TEAMS table simply consists of TEAMID and NAME.

My problem is that I need to get the right individual name for 2 values on
the same row and this is what I don't know how to accomplish in a 'all in
one go' query with the other params.

PROBLEM 2 (I am using an Access 2000 DB):

Again I basically poke the codes of player names into a line-by-line history
table so I'm not storing redundant data (ie the long player names) on each
row, but now that I want to query this historic info and link/display the
right names I can't do it. My query is as follows:

select HOMEPLAYERID, HOMEPLAYERGOAL, HOMEPLAYERASSIST, HOMEPLAYERRATING,
HOMEPLAYERMOM, AWAYPLAYERID, AWAYPLAYERGOAL, AWAYPLAYERASSIST,
AWAYPLAYERRATING, AWAYPLAYERMOM from MATCHLINES
where MATCHID='1'

Above is all the fields in my MATCHLINES table and this query works fine,
but it shows the player ids/codes and I want to link in my PLAYERS table so
that the HOMEPLAYERID and AWAYPLAYERIDs are substituted for the actual
player names, which are in my PLAYERS table. The PLAYERS table simply
consists of PLAYERID and NAME.

Can you help?

Many thanks.

I'm having trouble understanding this explanation. I suggest you open your
database in Access, go to the Queries tab and start experimenting with using
the Query Builder to work with your tables. Access has a pretty good online
help system that should help you. You should search for information about
joining tables. Once you have a query built using the GUI designer, switch
to SQL View to see what the sql should look like. Or better yet, save your
query and execute the saved query from asp. See:

I think what you are trying to do is a double join to the teams (Players)
tables.

In other words, all teams are in a table and any team can be either a home
team or an away team, correct? The same is true for the players?

SELECT Matches.*, Teams_1.*, Teams.*
FROM (Matches INNER JOIN Teams AS Teams_1 ON Matches.HOMETEAMID =
Teams_1.TEAMID) INNER JOIN Teams ON Matches.AWAYTEAMID = Teams.TEAMID;

I copied this directly from the SQL view in Access so I know it will work.

To do this graphically in Access, add the TEAMS table to your query TWICE.
Then draw a relationship between the HOMETEAMID to one and the AWAYTEAMID to
the other.

HTH,
John

SELECT Matches.*, Teams_1.*, Teams.*
FROM (Matches INNER JOIN Teams AS Teams_1 ON Matches.HOMETEAMID =
Teams_1.TEAMID) INNER JOIN Teams ON Matches.AWAYTEAMID = Teams.TEAMID;

Try that. Basically, you join to the TEAMS table twice: once for the home
team and once for the away team.
