I have a master table which had a corrupted autoincrement index field. I have repaired this using PDXRBLD.exe and can now access this table. However, I am now unable to open the 'slave' table which has a field linked to the previously corrupted index field of the master table. As it is a small table I can delete it and manually recreate the data but there must be a better way to solve this problem. Thank you in advance for your comments or suggestions.

There are only 13 records in the master table. After the repair their value is the same as originally. The problem is that I cannot open the details table because Database Desktop cannot open the master table when opening the details table. Thanks for your interest. Quote: "Bob Henderson" wrote...

Yep, I'll bet that's what happened. Bob, you've learned this the hard way: Never use an autoinc field unless you're content with any random value, and don't care what it is. Never use an autoinc field as a foreign key in another table. Make your key field an integer field, and write your own incrementing routine.

It won't be a problem to change the detail table as you recommend.
