Hello. I'm hoping someone can explain this. I suspect the answer is straight forward but I can't figure it out myself, and I've found no answers online.
Yesterday my work's IT department moved a network drive to another location. The old location still worked as read-only. I have two Access databases: One contains the tables and the other contains the forms and queries, and has links to the tables in the other files. In order to avoid having to use the linked table manager every time I move the databases, I use the \\network\address notation instead of drive letters, such that the database with the linked tables was pointing to the old, read-only location. I deleted the linked tables and relinked to them using the new location, and noticed that there was a discrepancy of 30 records I had entered through the forms not showing up once I linked to the tables in the new location.
It was clear that the database I use to enter data never actually inserted those records into the linked tables, but still acted as though it had in that it showed all records. Once I deleted the linked tables and linked to them again, those records completely disappeared. What's odd to me is that I'd entered these data into the database over a week ago. Why does Access take so long to synchronize the data between the linked tables and the actual tables? Are there any settings I can change to make sure the data are synchronized when I exit the application? Is it the ODBC refresh interval? If the default is 25 minutes (1500 seconds), does it mean that the data are never synchronized if I don't keep the database open for at least that long?? This is really puzzling.
I was able to go back to the old network location and get the old database showing all the records it's supposed to have. I had it import the linked tables as local tables and it looks like the local tables contain all records. This is not an ideal solution, but at least it seems like I recovered all the data.
