This is awesome.

Isn't just as simple as adding a count() and a group by?

SELECT MAGINUS_SUPPLIER.SUPPLIER_ACCOUNT

, MAGINUS_SUPPLIER.SUPPLIER_NAME,MAGINUS_SUPPLIER.ADDRESS1

, MAGINUS_SUPPLIER.ADDRESS2

, MAGINUS_SUPPLIER.ADDRESS3

, MAGINUS_SUPPLIER.ADDRESS4

, MAGINUS_SUPPLIER.ADDRESS5

, MAGINUS_SUPPLIER.ADDRESS6

, MAGINUS_SUPPLIER.POSTCODE

, MAGINUS_SUPPLIER.PAYMENT_TERM

, MAGINUS_BANK_DETAILS.BANK_SORT_CODE

, MAGINUS_BANK_DETAILS.BANK_ACCOUNT_NUM

, MAGINUS_BANK_DETAILS.BANK_REFERENCE

, xxxCustDelivDump.InvDate

, COUNT(*)

FROM MAGINUS_SUPPLIER

INNER JOIN MAGINUS_BANK_DETAILS...

That seems like a lot of work, when you could modify the original stored procedure to save the multiple result sets to a temp table and then return them all...
