All Implemented Interfaces:
DataStoreHelper, java.io.Serializable
Direct Known Subclasses:
WSConnectJDBCDataStoreHelper
public class ConnectJDBCDataStoreHelper
extends DataDirectDataStoreHelper
implements java.io.Serializable

ConnectJDBCDataStoreHelper is a DataStoreHelper implementation customized for the Microsoft JDBC driver for MS SQL Server 2000 and the unbranded Connect JDBC driver. SQLException mapping is handled by the DataDirectDataStoreHelper. If you have additional requirements on the Microsoft JDBC driver for MS SQL Server 2000 or the unbranded Connect JDBC driver consider subclassing this implementation.

Constructor Detail

ConnectJDBCDataStoreHelper

public ConnectJDBCDataStoreHelper(java.util.Properties props)
This ConnectJDBCDataStoreHelper constructor creates a new ConnectJDBCDataStoreHelper based on the DataStoreHelper properties provided. The properties parameter is provided only for future extensibility and is currently unused.

Parameters:
props - DataStoreHelper properties.
Method Detail

doStatementCleanup

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,

  • cursorName
  • escapeProcessing
  • fetchDirection
  • maxFieldSize
  • maxRows
  • queryTimeout

ConnectJDBCDataStoreHelper resets all of the statement properties listed above except for the cursorName 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.

Specified by:
doStatementCleanup in interface DataStoreHelper
Overrides:
doStatementCleanup in class GenericDataStoreHelper
Parameters:
stmt - the PreparedStatement.
Throws:
java.sql.SQLException - if an error occurs cleaning up the statement.
