Subject: Re: Cross Tab

No, DB2 UDB for i5/OS doesn't have a cross-tab/pivot table function built in.

Web query is probably your best bet.

However, you can actually manually perform the cross-tab function
using the CASE statement.

Given:

Period Category Sales
2002-01 Snacks 3000.25
2002-01 Beverages 2145.01
2002-01 Fruit 175.20
2002-02 Snacks 2167.40
2002-02 Beverages 2022.39

Select Period,
Sum(Case When Category='Beverages'
Then SalesAmt End) As Beverages,
Sum(Case When Category='Fruit'
Then SalesAmt End) As Fruit,
Sum(Case When Category='Snacks'
Then SalesAmt End) As Snacks
From Sales
Group By Period
Order By Period

Gives you:
Period Beverages Fruit Snacks
2002-01 2145.01 175.20 3000.25
2002-02 2022.39 -- 2167.40



In addition, on the web you'll find various utilities developers have
written to automate this process so that you don't have to know ahead
of time how many columns you'll need.

Here's one, (from which I took the above example)

My boss (the PC server guy) asked me if System i's SQL had a cross tab function. Never heard of it, but he said it was like a pivot table.

My searches in the SQL manuals, Info Center, and the srchives only turned up a reference in the IC to OLAP in Web Query for DB2.

Is there a cross tab function in SQL? We do have 5722-ST1 (DB2 Query Mgr and SQL DevKit) installed.

Thanks.
