Constant Crosstab Headings & functions to create queries

Michel Walsh has been most generous in his time over the years in giving,
in reply to several postings on the matter, a Function as a solution to
holding column headings constant, so that a cross tab query (the fields of
which would otherwise change depending on the input data) can be reliably
used as the basis of another Query, Report or Form. What, unfortunately, he
seems with similar consistency to avoid is telling us all how to actually
use that Function! Anyone got any ideas. Basically, it returns a string
starting "SELECT .....". How can I use a function generating a SQL
statement to actually create a useable Query?

You can create a QueryDef object, and set its SQL property to the SQL
statement generated by the function. As well, you can set the RecordSource
for a report equal to the SQL statement itself.

re: Constant Crosstab Headings & functions to create queries

I'm still learning the basics of VBA but it sounds to me like a
function-created-query can only be accessed within yet more VBA code ...?
Am I right in thinking I cannot use a VBA function to create a 'real' Query
as a layman would know it in the database window's list of queries?

CurrentProject.Connection.Execute _
"CREATE PROCEDURE qryBlah (parBlah Integer) AS DELETE * FROM tblBlah WHERE
fldTransactionID = parBlah"

ACXP

gives ... for qryBlah

PARAMETERS parBlah Long;
DELETE tblBlah.fldTransactionID, *
FROM tblBlah
WHERE (((tblBlah.fldTransactionID)=[parBlah]));

No that's not correct.


Sub CreateQueryDAO()
Dim db As DAO.Database
Dim qdf As DAO.QueryDef

Set db = CurrentDb()
Set qdf = db.CreateQueryDef("MyQuery")
qdf.SQL = "TRANSFORM ...

Set qdf = Nothing
Set db = Nothing
End Sub
