When using Lotus Domino/Notes JDBC Driver 1.5 Toolkit with a Prepared Statement the following exception is thrown. This error occurs with both UPDATES and INSERTS. The IN value and paramters being set are correctly macthed in both my statements. This appears to be a problem with the driver. I have tested the operation by reducing the values that get passed in and that seems to work. However, my last to values that need to be set are Date/Time fields in Notes, so I pass in java.sql.Date values and this exception is raised. Any ideas on how the driver handles NULL values for Date/Time, some of the records will have NULLs. SQLException: [Lotus][Domino Driver for JDBC]Wrong number of parameters.
