Many thanks for your message + help.

I have made some tests, which exactly confirm your information. Seeing
things a bit clearer now. The prepared statement you suggested not has made
a big difference, but i will have that in mind.

Conclusion: To limit memory usage, execution time and bandwidth with large
result sets (Columns X Rows) i HAVE to use "UseDeclareFetch=1" and
"Fetch=xxx".
"Fetch=xxx" with  "UseDeclareFetch=0" does not help.

I still hope there is a way to get RowCount without ReConnecting,
ReSelecting and halve the performance.

regards
