Method Detail

initializeJdbcConnection

public void initializeJdbcConnection(JdbcConnectionDescriptor jcd,
                                     Connection conn)
                              throws PlatformException

Sybase Adaptive Server Enterprise (ASE) support timestamp to a precision of 1/300th of second. Adaptive Server Anywhere (ASA) support timestamp to a precision of 1/1000000tho of second. Sybase JDBC driver (JConnect) retrieving timestamp always rounds to 1/300th sec., causing rounding problems with ASA when retrieving Timestamp fields. This work around was suggested by Sybase Support. Unfortunately it works only with ASA.
