How to fix the issue of access not being able to delete columns.

If deleting columns in ACCESS is not working, you can refer to the following solutions:

1. Make sure you have the necessary permissions to carry out the deletion operation. If you are connected to the database through a network, ensure you have the required permissions to modify the table structure.
2. Make sure that the column to be deleted does not exist in other places, such as triggers, indexes, or constraints, etc. If there are associated objects, those objects must be deleted or modified first before the column can be deleted.
3. Make sure you are using the correct syntax to delete a column. In ACCESS, the syntax for deleting a column is as follows:
4. Modify the table by removing a column.
5. Make sure you correctly specify the table and column names you want to delete.
6. If none of the above methods work, try creating a new table and copying the data from the old table to the new one. Exclude the columns to be deleted in the new table. Then, delete the old table and rename the new table to the original table’s name.

These are some common solutions. If the problem still cannot be resolved, it is recommended to refer to the official documentation of ACCESS or consult the relevant technical support.
