using MS Access 2010, editing a form, 3 tables, one table is "one to many" and want to have query across one row - sql

Question

Example:
(using a comma, to show columns & "A_", "B_", "C_" to show tables)
I currently have...
A_John, A_Doe, B_MemStartDate, C_Date,
A_John, A_Doe, B_MemStartDate, C_Date,
A_John, A_Doe, B_MemStartDate, C_Date,
I would like Table "C" columns to be pulled by Course but shown as the "Date" column... in other words, example, where Course = 1, use Date... etc...
The table would have each member's course history.
MemberID, CourseID, Date
JohnDoe, Course1, 10-10-13
JohnDoe, Course2, 10-11-13
JohnDoe, Course3, 10-12-13
The table C is the one to many of course, with the goal to show the date that the course was taken as I would title the columns with the 3 different courses I want to show... (I want to pull only 3 different courses)
I would like to have them in a row...
A_John, A_Doe, B_Start Date, C_Course1Date, C_Course2Date, C_Course3Date
Sorry for the lack of experience in my question, but I usually get by with "copy/paste"...LOL
Keeping in mind I am using Access... can I do this?
Clarifying... sorry don't know how to do tables in basic html so have commas
Have this. Pulling from 3 different tables where the member# is unique and joined.
MEMBER, STARTDATE, STATUS, COURSE, COURSEDATE

LaraBentt, 12-01-2012, Inactive, Workshop2, 02-13-2012
LaraBentt, 12-01-2012, Inactive, Workshop3, 02-28-2012
Want this...
MEMBER, STARTDATE, STATUS, WORKSHOP1, WORKSHOP2, WORKSHOP3
JohnSmith, 08-01-2013, Active, 10-20-2013, 10-13-2013, 10-28-2013
LaraBentt, 12-01-2012, Inactive, 02-20-2012, 02-13-2012, 02-28-2012
Tables columns are basically like this...
Table 1 - tblMember (one - one)
MEMBER, STARTDATE
Table 2 - tblRegStatus (one - one)
MEMBER, STATUS
Table 3 - tblCourses (one to many)
MEMBER, COURSE, COURSEDATE
Hope this explains it better!

Answer 1

Your amendment to your question made it much more clear.
One of the problems you are going to encounter is if you have someone that has registered for the same course, twice. There has to be the understanding that you are only showing the most recent registration per person. Now that we understand that caveat - lets look at how you can build this.
The simplest way of building this is to change the query type from Select to Crosstab. This is done through the Access interface.
For each of the fields in the query, set the Total and Crosstab values to:
MemberName: Total = *Group By* Crosstab = *Row Heading*
StartDate: Total = *Group By* Crosstab = *Row Heading*
Status: Total = *Group By* Crosstab = *Row Heading*
CourseName: Total = *Group By* Crosstab = *Column Heading*
CourseDate: Total = *Max* Crosstab = *Value*
This will result in query results such as:
MemberName StartDate Status Biology English Math
---------- --------- ------ ------- ------- ----
John 10/1/2013 Active 11/14/2013 12/1/2013
Matthew 9/1/2013 Inactive 1/1/2013
Peter 8/7/2013 Active 1/1/2013 4/1/2013
Sam 1/14/2013 Inactive 11/14/2013
William 5/19/2013 Active 1/1/2013 4/1/2013
The advantage to the crosstab is that it will automatically add columns as there is data.
You have to construct your query (the joins) to give you the data that you want however. For example - do you want to show members that have no courses on the list? Do you want to show courses that have no enrollment?
Microsoft has a page on using crosstab queries:
http://office.microsoft.com/en-us/access-help/make-summary-data-easier-to-read-by-using-a-crosstab-query-HA010229577.aspx
If you want to hard code your three columns, you can also manually pivot the data. Again - keep in mind that we are using the Max aggregate, so only the latest courses will show. With a manual pivot you also need to remember that it will be limited to the data you are requesting.
Take your select query, right click and click "Totals" to show the Totals row. You can also click on the Totals icon in the ribbon under Query Tools / Design.
Set up your three columns:
MemberName: Total = *Group By*
StartDate: Total = *Group By*
Status: Total = *Group By*
Now add in a separate field for each course you wish to include. In the "Field" definition enter the following.
Science: IIf([CourseName]="Science",[CourseDate],Null)
Biology: IIf([CourseName]="Biology",[CourseDate],Null)
Math: IIf([CourseName]="Math",[CourseDate],Null)
English: IIf([CourseName]="English",[CourseDate],Null)
Set the "Total" definition value to "Max".
That should get you the results you are looking for.
