Please tell me if there is a size limitation for ResultSet

Question

Hi,
I have a sql select * from....and the following code. If I limit the rows from the query results(rows 1 to 500), there is no problem. But if I get all the query results once , the ResultSet line get error message OutOfMemoryError. (I have large html infor. in the query result).
So my question is if there is a size limitation for ResultSet? Do I have to break down the query results?
PreparedStatement st = conn.prepareStatement(sql.toString());
ResultSet rs = st.executeQuery();Thanks in advance,
Katie

Hi,
Thanks for the link, but I didn't see any answers for
my question.....my question is if there is a way that
ResultSet hold all the query results?
Thanks again,
KatieDid you read this part:
" Result Set Limitations and Downgrade Rules
Some types of result sets are not feasible for certain kinds of queries. If you specify an unfeasible result set type or concurrency type for the query you execute, the JDBC driver follows a set of rules to determine the best feasible types to use instead.
The actual result set type and concurrency type are determined when the statement is executed, with the driver issuing a SQLWarning on the statement object if the desired result set type or concurrency type is not feasible. The SQLWarning object will contain the reason why the requested type was not feasible. Check for warnings to verify whether you received the type of result set that you requested, or call the methods described in "Verifying Result Set Type and Concurrency Type".
- There was a part after that that also talked about work arounds.
