About controlling updates

When Sybase WorkSpace generates the basic DataWindow object, it defines whether the data is updatable by default as follows:

If the DataWindow object contains columns from a single table and includes that table's key columns, Sybase WorkSpace defines all columns as updatable and specifies a nonzero tab order for each column, allowing users to tab to the columns.
If the DataWindow object contains columns from two or more tables or from a view, Sybase WorkSpace defines all columns as not being updatable and sets all tab orders to zero, preventing users from tabbing to them.

You can accept the default settings or modify the update characteristics for a DataWindow object.

If using a Stored Procedure or External data source If the data source is Stored Procedure or External, you can use the getNextModified method to write your own update mechanism in the Java code.
