By transpose do you mean a crosstab?

There is a command in SQL 2005 called PIVOT

In SQL 2000 there is are many workaround solutions. The best solution depends on your actual issue and what the realted systems are.


But basically a crosstab is best done in the front end, if you have one.

I've never heard the term cross tab, but I'll look in the PIVOT command.

I am not familiar with that term.  Could you explain what you are expecting?

Transpose is when you take a table and flip it 45 degrees so that all the columns are now rows and all rows are now columns.

Then indeed PIVOT/UNPIVOT is what you are looking for...

Hope this helps...

If I have
SELECT Date, Cost, Clicks, Impressions
FROM MyTable
GROUP BY Date

How can I pivot that statement to return each column as an individual Date?
Thanks

OK. First thing is that wiht PIVOT you need to explicilty define the output columns. In other words you need to know which dates you want to show beforehand.

There are stored procedures around that will do this for you too.

But really you are much better off doing this in the user interface, not in the database.

Here is a link to a dynamic crosstab stord procedure:

Here is link backing up the fact that you should do this in the presentation layer:
