From: cubew00t on 22 Dec 2009 06:22 Hello I am dealing with some unfriendly import files which import as: timestamp position name 001 2 Jon 001 3 Bob 001 1 Ann 001 4 Mike 002 1 Joe 002 2 Sue 003 1 Jeff 004 5 James 004 1 Andy 004 2 Beth 004 4 Mitch 004 3 Chris And would like to create a new table that displays thusly: timestamp position1 position2 position3 position4 position5 001 Ann Jon Bob Mike 002 Joe Sue 003 Jeff 004 Andy Beth Chris Mitch James By browsing this forum the closest I have come to a solution is: SELECT pos1.timestamp, pos1.name AS position1, pos2.name AS position2 FROM table1 AS pos1 INNER JOIN table1 AS pos2 ON pos1.timestamp = pos2.timestamp WHERE (((pos1.position)=1) AND ((pos2.position)=2)) I cannot figure out how to expand this to my specs, any help is much appreciated. I don't understand generalities (having started on access today). Can you be specific as to my particular situation and what I need to do the get the desired output. Thank you.

Assumption is that there is no duplication of the combination of timestamp and position TRANSFORM First([Name]) as TheName SELECT Timestamp FROM YourTable GROUP BY Timestamp PIVOT Position In query design view == Add your table == Add Timestamp, Position, and Name fields == Select Query: Crosstab from the menu == Change Group by to First under the name field == Select Value under the name field == Select Row under timestamp == Select Column under position John Spencer Access MVP 2002-2005, 2007-2009 The Hilltop Institute University of Maryland Baltimore County cubew00t wrote: > Hello I am dealing with some unfriendly import files which import as: > > timestamp position name > 001 2 Jon > 001 3 Bob > 001 1 Ann > 001 4 Mike > 002 1 Joe > 002 2 Sue > 003 1 Jeff > 004 5 James > 004 1 Andy > 004 2 Beth > 004 4 Mitch > 004 3 Chris > > And would like to create a new table that displays thusly: > > timestamp position1 position2 position3 position4 position5 > 001 Ann Jon Bob Mike > 002 Joe Sue > 003 Jeff > 004 Andy Beth Chris Mitch James > > By browsing this forum the closest I have come to a solution is: > > SELECT pos1.timestamp, pos1.name AS position1, pos2.name AS position2 > FROM table1 AS pos1 INNER JOIN table1 AS pos2 > ON pos1.timestamp = pos2.timestamp > WHERE (((pos1.position)=1) AND ((pos2.position)=2)) > > I cannot figure out how to expand this to my specs, any help is much > appreciated. > > > I don't understand generalities (having started on access today).
