# 3243 Database Catalog Table Structure Checksums Calculating Incorrectly

I must move a table in database on Pc1 into another same database on Pc2 (Overwrite Table to Pc2 if is alreasy exist)

Db AZ0001
Tab Clienti.xxx --------- > Pc2
Db AZ0001
Tab Clienti.xxx

This is message error:

ElevateDB Error #100 There is an error in the metadata for the table Clienti (The internal version does not match the version in the configuration or catalog)

Comments Comments
The problem was that the checksum calculation was incorrectly including the internal object ID in the calculation. Therefore, if two tables were identical in terms of structure, but had different internal object IDs because they were created in a different order in each database catalog, EDB would incorrectly think that they were different.

To "fix" the checksum, make sure that you're using 2.03 Build 17 or higher, and perform the following steps with each table that needs to be copied:

1) Alter the table and add a dummy INTEGER column to the table.
2) Alter the table again, and remove the dummy INTEGER column.

After completing these steps, EDB will have recalculated the checksum properly, and you will be able to move around the table files without getting an error.

Also, the error message has been changed a bit to reflect that the structure is the source of the problem, not an internal version number (old design).
