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.

[Zope] dtml-in: total??
Hello, 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? Bye, Edwin Martin. --- The world is moving so fast these days that the person who says it can't be done is generally interrupted by someone doing it. -- Harry Emerson Fosdick ___ Zope maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev )
