public class CloudscapeNetworkServerDataStoreHelper
CloudscapeNetworkServerDataStoreHelper
is a DataStoreHelper
implementation
customized for the Cloudscape database when running using the Cloudscape NetworkServer framework.
When mapping a SQLException
, the SQLException
mappings from the
CloudscapeNetworkServerDataStoreHelper
and
CloudscapeDataStoreHelper
are searched first, and subsequently, if no match is
found, the SQLException
mappings from the GenericDataStoreHelper
are searched.
If you have additional requirements on Cloudscape you should consider subclassing this
implementation.
Note: This class and its methods can not be called or referenced directly by user applications.
SQLException
mappings specific to the CloudscapeNetworkServerDataStoreHelper
are the following:

public CloudscapeNetworkServerDataStoreHelper(java.util.Properties props)
CloudscapeNetworkServerDataStoreHelper
constructor creates a new
CloudscapeNetworkServerDataStoreHelper
based on the DataStoreHelper
properties provided. All implementations inheriting from a data store helper
must supply this same list of properties to their super class by invoking the
constructor of their super class with the list of properties.

public void doStatementCleanup(java.sql.PreparedStatement stmt) throws java.sql.SQLException
This method cleans up a statement before the statement is returned to the statement cache. This method is called only for statements that will be cached. It is called only if at least one of the following statement properties has changed,
CloudscapeDataStoreHelper
resets all of the statement properties listed above
except for the queryTimeout
property.
The following operations do not need to be included in the statement cleanup since they are automatically performed by WebSphere when caching statements,
setFetchSize(0)
clearParameters()
clearWarnings()
A helper class implementing this method may choose to do additional cleanup for the statement. However, this should never include closing the statement, since the statement is intended to be cached.
