Subject [jira] [Commented] (DERBY-6880) Update failing with java.sql.SQLDataException
Date Fri, 01 Apr 2016 03:18:25 GMT

    [ https://issues.apache.org/jira/browse/DERBY-6880?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15221076#comment-15221076
] 

Bryan Pendleton commented on DERBY-6880:
----------------------------------------

In the code:

{code}
                for(col=1;col<=maxColumns;col++)
                {
                    ColumnDescriptor cd = td.getColumnDescriptor(col);
                    if(cd.isAutoincrement())
                    {
                        break;
                    }
                }

                if(col <= maxColumns)
                {
                    DataValueDescriptor dvd = row.cloneColumn(col);
                    identityVal = dvd.getLong();
                }
{code}

is where we go astray. The for loop locates the correct column descriptor,
it is for the "id" column of table "pipeline_command".

But the table descriptor in "td" is not accurate for use with the data in "row".

In this particular case, "td" describes the underlying "pipeline_command" table,
and it appears to have all the relevant columns just as you would expect, and
so column 1 is indeed the autogenerated "ID" column.

However, column 1 of "row" is nothing the same at all. "row" is a ValueRow,
and has only 3 columns, in my case the three columns are:
  - the old value of the "status" column
  - the new value of the "status" column
  - some sort of value that is displayed as "(1,8)", which I haven't decoded yet.

I think that "row", at the time when we are running, is some sort of intermediate
object, and the code in UpdateResultSet is getting all confused because it
is trying to use the underlying table descriptor to interpret the values in "row",
but "row" is not a row from the base "pipeline_command" table anymore, it is
some intermediate "old-value,new-value" row that has been constructed by the query.

Anyway, that's as far as I got today fooling around with the reproduction script.

> Notably, I have tried executing the same update via other means (for example, manually
via SquirrelSQL, and via the ORMLite framework) and the update succeeds. This may be due to
the exact JDBC APIs they are using (for example, SquirrelSQL is not using a prepared statement,
and ORMLite updates all the columns when it updates a table rather than just some of them).
