Does Network Server support scroll sensitive read-only and updatable resultsets?
--------------------------------------------------------------------------------
Key: DERBY-154
URL: http://issues.apache.org/jira/browse/DERBY-154
Project: Derby
Type: Bug
Components: Network Server
Versions: 10.0.2.1
Reporter: Mamta A. Satoor
Derby in embedded mode does not support scroll sensitive resultsets in both
read-only and updatable modes. But when I write a simple test program in
Network Server configuration, it appears that scroll sensitive resultsets are
supported both in read-only and updatable modes. Is that correct?
Connection con =
DriverManager.getConnection("jdbc:derby:net://localhost:1527/db1drda;create=true:retrieveMessagesFromServerOnGetMessage=true:deferPrepares=false;",
"app", "app");
Statement s = con.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE,
ResultSet.CONCUR_READ_ONLY);
SQLWarning warnings = con.getWarnings();
while (warnings != null)
{
System.out.println("warnings on connection = " + warnings);
warnings = warnings.getNextWarning();
}
System.out.println("Did we get TYPE_SCROLL_SENSITIVE? " +
(s.getResultSetType() == ResultSet.TYPE_SCROLL_SENSITIVE));
System.out.println("Did we get CONCUR_READ_ONLY? " +
(s.getResultSetConcurrency() == ResultSet.CONCUR_READ_ONLY));
s = con.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE,
ResultSet.CONCUR_UPDATABLE);
System.out.println("Did we get TYPE_SCROLL_SENSITIVE? " +
(s.getResultSetType() == ResultSet.TYPE_SCROLL_SENSITIVE));
System.out.println("Did we get CONCUR_UPDATABLE? " +
(s.getResultSetConcurrency() == ResultSet.CONCUR_UPDATABLE));
And the output in Network Server mode for above test case is
Did we get TYPE_SCROLL_SENSITIVE? true
Did we get CONCUR_READ_ONLY? true
Did we get TYPE_SCROLL_SENSITIVE? true
Did we get CONCUR_UPDATABLE? true
