> Rolling back a transaction can leave a table in an inconsistent state if the table has
been previously altered through the addition of new columns. It appears that if newly added
columns have not been changed from their default value, then when a transaction which sets
new values for these columns is rolled back the new columns are not restored to their previous
values.
> Attached is an ij script with fairly minimal steps to reproduce the problem on Derby
10.6.2.0 and 10.8.2.2 (Win7 x64, Sun 32-bit JRE 1.6.0.26). Expected and observed output also
attached.
> Would appreciate any suggestions as to a workaround for this issue. Running SYSCS_UTIL.SYSCS_COMPRESS_TABLE
on the table after adding the columns seems to avoid the problem but may be just masking the
issue.
