Hi,

I need to change the CHARACTER SET of columns in a table from
UNICODE_FSS to ASCII.
Column 1 is of type VARCHAR(14)
Column 2 is of type CHAR(1)
Using IBExpert, when I change the CHARACTER SET of column 1 everything
seems fine.
But when I change column 2 I get an error: arithmetic exception, numeric
overflow, or string
truncation, when making a backup of the database.

Am I performing illegal operations here?

TIA
Constantijn
