# 3456 Altering a Table Can Result in Error #100

---

Steps to reproduce the 100 error with EDB 2.05b8.

1. Create a new database with a single table. In that table, add just a single field. I don't think the type matters, but I chose a boolean field.

2. Open the database with EDB Manager and alter the table to add another field.

3. Close EDB Manager and re-open it.

4. Open the table to produce the 100 error.
