Vlad, looking at sql2008 (part2, foundation, 11.10 - alter table statement) one can read in <add column definition> that when new column is added, and this is base (not generated) column, and this is not identity column then every value in this column is it's default value. And it's mentioned in <alter column definition> <set column default clause> that new default value is stored in column descriptor, but nobody mentions that it should be changed for existing records. I.e. according to standard old (interbase origined) behavior was a bug and current one is correct. ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot Firebird-Devel mailing list, web interface at https://lists.sourceforge.net/lists/listinfo/firebird-devel
