I'm making a generic DTML-method which shows a bar like AltaVista does:
[ < previous] [1] [2] [3] [4] [next > ]
I need to know the number of rows the database returned.
In appendix A of the Zope book, I see I can use total-name etc.
How can I get the total number of rows, independent of column names?
Can I do it without rewriting the SQL-queries? You can.
It is even prepared for you: "dtml-in" defines variables "previous-batches" and "next-batches" describing all previous and following batches. It you do not like this prepared solution, you can use "sequence-length", another "dtml-in" defined variable, to access the length of the sequence. Dieter
