I know that there are many pros to using Multi row fetch. Buts are there really any cons to using row set ?
i have a scenario , where i will be be running dynamic queries (have a webserive interface with dotnet ) based on some fields sent from the front end. The resultant can vary anywhere from zero to 2K . Is multirow fetch a good candidate for this?

by resultant do you mean result set anywhere from 0 to 2000 rows?
or do you mean something else.
multi-row fetch means
1. less calls to db2
2. less transmission of data
3. larger area required to contain the data.(row size X number of rows)
4. different handling of sqlcode and sqlerrcd(3) (never do spell that correctly)
now, do any of these considerations discount your use of mult-row fetch?
Limit your number of rows per multi-row fetch to be in the range of 10-100, so that you gain benefit of multi-row fetch.For more number of rows the benefit becomes negligible and you will also introduce overhead of having larger array of host variables to hold the fetched values. Thanks.
