Re: Multipage JDBC result
What database are you using ? We use the MySQL database and have effectively used the limit clause to work with a limited set of records. we just store the query condition in the forms and work with that in every page. - Navneet [EMAIL PROTECTED] said the following on 18/09/2003 1:56 AM: It seems that it pulled the whole JDBC resultset into the memory at one time(correct me if I am wrong at this point) since my data sets will be very huge, I don't think it is a good idea to pull down all the data to the session for paging. Any better solution /examples? very appreciated!!

RE: Multipage JDBC result
Julie, In Oracle, you can also limit the # of records returned and the the starting point using rownum. Your JDBC driver can also limit the # of ResultSets. Check the JavaDoc.

RE: Multipage JDBC result
You didn't specify whether you want to do client-side or server-side paging. Assuming you want to pull the whole resultset in one shot, but have a paged presentation, check out the Struts Layout taglibs. They have a very handy pager widget that uses javascript and tags. If you want to do server side, this is really more of a database issue than a struts issue, and a lot will depend on what database you are using. The downside is you have to do a round-trip to the server for the next page. Search on Google for Scrollable resultsets. Almost all JDBC drivers support them. Another method is to specify a LIMIT offset in your query to specify the number of rows you want returned and where in the resultset you want to return from. Exact syntax is database-specific.
