    Unanswered: db2 type 4 driver result set fetch size

    I m using jdbc code to retrieve records in db2 and using type 4 driver db2jcc.jar.
    Does it supports setting for fetch size on statement or prepared statement or not?

    Because i have 1 million records in my database,if the result set loads all at one shot then my java program will through out of memory exception.

    thanks in advance

    when declaring a cursor and fetching from this cursor there is a blocking mechanism
    I believe you get blocks of data, whenever you fetch new data
    the block is limited in size (8k I believe)
    should be verified..
    there are some topics in doc regarding this.. see

    Not sure, I think you can control that with the setting of "enableRowsetSupport" described here: DB2 Database for Linux, UNIX, and Windows
