Hi All,

Bob - You were right the other post did not address this!

This is the process that is followed to populate an Excel MIS. The
user clicks a button in Excel to trigger it.

1) Financial database tables linked to Access, Access query to
retrieve required data, Access crosstab query to manipulate data to
required format, import crosstab data to Excel.

This is what l would like to do:

2) Financial database tables, query to multiple tables and retrieve
data into Excel, run sql crosstab query
on retrieved data in Excel.

I know how to download the financial tables using ADO & SQL (using the
code posted below, found by searching this newsgroup) but l cant seem
to get it to run a simple query on 1 table let alone over multiple
tables. So my questions re 2) a

a) What is wrong with the SQL code below, which queries 1 table. Is it
my syntax? I am not an SQL expert.
b) Can you use SQL to query multiple tables from within the Excel VBA
environment.
c) I assume that the results of the intial query have to be written
to
an Excel sheet
d) Can l then use a SQL statement within VBA to create a sheet with
the results of the crosstab query?
e) If b) can be done does anybody have any example code please? or can
anybody tell me how to amend my existing code?
f) Will 2) be quicker / more efficient than 1)


I have been told by a database expert that because of the layout of
the tables within the financial database a single query cannot give
the desired result. I am not an expert on SQL.


I hope l have explained myself clearly.


All advice gratefully received.

The QueryMaster file at Debra Dalgleish's website has an example of a VBA
driven CrossTab query which runs directly against joined MS Access tables.
Perhaps it can help you resolve your issue.

Is that something you can work with?

Hi Ron,

Thanks for responding.

I have already got a solution that works using Access tables that are
'joined' but l felt that it is to slow & inefficient.

I was hoping to develop a solution in VBA that uses SQL to directly
query across multiple tables in the financials database (Sage). I
would then apply an SQL statement to the results retrieved to Excel
(ie the crosstab query)

I am getting there SLOWLY and the example workbook will help me build
the SQL code and points me in the right direction re manipulating the
data retrieved into the Excel workbook.

I hope all this work actually results in quicker code!
