Srikanth,
Aside from seconding Tim (your database is *not* normalized), the PIVOT
function is only available one of 2 ways:
SQL-ONLY, FIXED COLUMN: If you know your categories in advance, you can
write a complex view using outer joins, sub-selects, and aggregates.
Imagine that we know your types of marketing to be limited to TV, NEWS
and POSTER:
SELECT client_address, tv_totals.totaltv, news_totals.totalnews,
poster_totals.totalposter
FROM clients
LEFT OUTER JOIN (SELECT client_address, sum(tv_spots) as totaltvFROM clientsGROUP BY client_address ) AS tv_totalsON
tv_totals.client_address= clients.client_address
LEFT OUTER JOIN (SELECT client_address, sum(news_ads) as totalnewsFROM clientsGROUP BY client_address ) AS
news_totalsONnews_totals.client_address = clients.client_address
LEFT OUTER JOIN (SELECT client_address, sum(posters) as totalpostersFROM clientsGROUP BY client_address ) AS
poster_totalsONposter_totals.client_address = clients.client_address;
DYNAMIC METHOD: This requires an external programming language, and I'm
not going to write it for you! However, pick you favorite procedural
language (tcl, perl, or C) and write the following:
1. Do an select distinct to obtain each value in the column you want to
use in the headers. Load this series into an array.
2. Dynamically generate query text, adding a column and a LEFT OUTER
JOIN as above into the query for each value in your array.
This method is a lot of work for both you and the server. Why do you
think that MS Access often crashes on a large "crosstab" query?
