Cross Tab - Storing different dates (Meeting1, Meeting2, Meeting 3 etc) in the same column

Question

I need to keep track of different dates (dynamic). So for a specific Task you could have X number of dates to track (for example DDR1 meeting date, DDR2 meeting date, Due Da

Answer 1

I don't have personal experience with the pivot operator, it may provide a better solution.

But I've used a case statement in the past

SELECT 
    TaskDescription, 
    CASE(DateTypeID = 1, Tasks_DateType.Date) AS DDr1, 
    CASE(DateTypeID = 2, Tasks_DateType.Date) AS DDr2,
    ...
FROM Tasks 
    INNER JOIN Tasks_DateType  ON Tasks.ID = Tasks_DateType.TasksID
    INNER JOIN DateType ON Tasks_DateType.DateTypeID = DateType.DateTypeID
GROUP BY TaskDescription

This will work, but will require you to change the SQL whenever there are more Task descriptions added, so it's not ideal.

EDIT:

It appears as though the PIVOT keyword was added in SqlServer 2005, this example shows how to do a pivot query in both 2000 & 2005, but it is similar to my answer.
