I have a Application which will update any of the field in a table(table with four fields with null as default and have a Unique key which includes all the fields of the table and hence no primary key associated with the table).Application using ROWID to update the record in the table(because table does not have any key field) .Application selects ROWID of the record when it selecting record for the update and uses the same while it updating back to the table. Application is able to update the record in the table as intended and my dought is is there any risk involed in using the ROWID of the record to update.
Quick suggestions will be appriciated.....
