java - Netezza Streaming ResultSet -

-

i having memory issues because trying read huge resultset netezza database. netezza support kind of "streaming" resultset mysql does? if not, limiting fetch size work instead?:

stmt.setfetchsize(50);  conn.setautocommitmode(false);

if want pull rows store in file, best best use remote external table.

here example creates transient remote external table on jdbc. invoke bulk export/load funciontality provided jdbc driver, , create pipe delimited text file.

create external table 'c:\mytest.txt'  using (delimiter '|' remotesource 'jdbc' ) select * table1;

you can call using conn.createstatement().execute, , have add change file specification c:\mytest.txt escape existing backslash.

you can read more external tables in documentation here.

you can use setfetchsize, way. i'm not sure solve memory issue though.
