Subject [jira] [Commented] (DERBY-5201) Create tools for reading the contents of the seg0 directory
Date Fri, 27 Jan 2012 17:34:14 GMT

    [ https://issues.apache.org/jira/browse/DERBY-5201?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13194936#comment-13194936

Steve Ferguson commented on DERBY-5201:

Thanks very much for this. 2 pieces of feedback.

 If I provide a data signature, and a row contains a column with a null value, and Exception
is thrown and the program exists. I put a try catch ignore Throwable block around  dvd.readExternalFromArray(
is ); to circumvent this. 

I think it would nice if a data signature is present to add an XML element to output the name
of the column in addition to its index. 

I also found this link helpful in conjunction with the tool to query out my ddl to pass into
the tool as a data signature for tables with lots of columns.

without disturbing their contents.
