I am new to MySQL and navicat as well. I have been creating a database in Access and now adding records. I added about 50 records earlier and then saved them to my flashdrive to import the new data in navicat using the import wizard. The reason I have to save to FlashDrive is I dont have Access on the pc at work, and I dont have Navicat on my laptop. Complicated I know. Anyway, the first time I imported, I selected "Copy: Delete all records from destination and repopulate the source..Woked fine. Next time I tried to add more records, it completes and says unsuccessful. Tried many times. Can someone tell me what causes the Unsuccessful error?? Thanks for any help!
