#87 — java resultset

  To: comp.lang.java.databases
Hi

Can I create a resultset that have all the specified columns? And, I have to
populate it with data. When the database is offline, then I can simulate it
to test my code. Please provide simple example.

Thanks

A resultset is stored in memory - I'm unsure what you mean about 
"offline". To get all of the columns, ask for all of the columns.

A simple resultset example:

java.sql.Connection c = DriverManager.getConnection("your driver and 
path to db", "your db user id", "your db password");
Statement get = c.createStatement(ResultSet.TYPE_SCROLL_INSENSITIVE,
                           ResultSet.CONCUR_READ_ONLY);
ResultSet rs = get.executeQuery("your query");

//use your result set from here

The newer RowSet interface lets you disconnect from the database while using 
the results, unlike normal ResultSets.
