One more: rowcounts with DODS standalone!

Thanks Alfred,

That was exactly what I needed! By accident I stumbled
over the selectCount() method which seems to be the
solution to another problem we are facing: how to
count the number of rows of a query!

My question is: does selectCount() cache the results?
Or is it recalculated all the times it is called?


Thanks in advance!

Axel

Hi !

xxxQuery classes support "readSkip" and
"setDatabaseLimit" methods to 
do
that ! "databaseLimitExceeded" even tells you, if
there would be more
data following...

Hi!

I have a practical question concerning browsing of
tables with DODS (standalone). I need to retrieve the
contents of a table in pages. In the old version of
DODS I constructed manually a query using the SQL
OFFSET and LIMIT feature.

What would be the best DODS way to browse a table,
page for page, without the need to get the entire
table at once and throw away the unneeded parts?

Thanks in advance,

   Axel
