Subject [jira] Created: (DERBY-2425) ResultSetMetaData.getColumnDisplaySize() returns a negative value for BLOB columns for client
Date Thu, 08 Mar 2007 20:28:24 GMT
ResultSetMetaData.getColumnDisplaySize() returns a negative value for BLOB columns for client

----------------------------------------------------------------------------------------------

                 Key: DERBY-2425
                 URL: https://issues.apache.org/jira/browse/DERBY-2425
             Project: Derby
          Issue Type: Bug
          Components: Network Client
    Affects Versions: 10.3.0.0
            Reporter: Kathey Marsden
            Priority: Minor



Client getColumnDisplaySize on a BLOB(1G) column returns 
-2147483648

embedded returns  2147483647

In client, the issue is that for binary values it multiplies the length * 2 and this overflows
the int range.
return (int) (2 * sqlLength_[column - 1]);
