Determining If a Database Supports Scrollable Result Sets</h3>
A scrollable result set allows the cursor to be moved to any row in
the result set. This capability is useful for GUI tools that browse
result sets.
<P> There are two types of scrollable result sets. An
<font color="#0066ff"><i>insensitive</i></font> scrollable result set is one where the values captured
in the result set never change, even if changes are made to the table
from which the data was retrieved. A <font color="#0066ff"><i>sensitive</i></font> scrollable result
set is one where the current values in the table are reflected in the
result set. So if a change is made to a row in the table, the result
set will show the new data when the cursor is moved to that row.
<pre>
try {
DatabaseMetaData dmd = <font color="#0066ff"><i>connection</i></font>.getMetaData();
if (dmd.supportsResultSetType(ResultSet.TYPE_SCROLL_INSENSITIVE)) {
// Insensitive scrollable result sets are supported
}
if (dmd.supportsResultSetType(ResultSet.TYPE_SCROLL_SENSITIVE)) {
// Sensitive scrollable result sets are supported
}
if (!dmd.supportsResultSetType(ResultSet.TYPE_SCROLL_INSENSITIVE)
&& !dmd.supportsResultSetType(ResultSet.TYPE_SCROLL_SENSITIVE)) {
// Updatable result sets are not supported
}
} catch (SQLException e) {
}
