Handling Errors in Table Mapping

Whenever you perform any type of comparison function between a data source and an in-memory data representation, there is potential for error. Errors can occur when a data source and its corresponding dataset do not share uniform numbers of columns, or when column types in a data source do not correspond to the column types in the dataset. In addition, other, internal errors can occur for which there is no designtime workaround. You can use both the MissingMappingAction property and the MissingSchemaAction property to respond to errors in your table mapping operations. Use the MissingMappingAction when you want to specify how the adapter should respond when the mapping is missing. Use the MissingSchemaAction when you want to specify how the adapter should respond when it tries to write data to a column that isn't defined in the dataset.
