[jira] [Commented] (DERBY-6836) syscs_import_data_lobs_from_extfile can not read data past 2GB

    [ https://issues.apache.org/jira/browse/DERBY-6836?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14903718#comment-14903718 ] 

Rick Hillegas commented on DERBY-6836:
--------------------------------------

A similar defect probably affects SYSCS_UTIL.SYSCS_EXPORT_TABLE_LOBS_TO_EXTFILE. Perhaps we could use a Long or a BigInteger instead.

> syscs_util.syscs_import_data_lobs_from_extfile() imports data from .csv file.
> For binary data, in csv is expected a reference, where should be data read from.
> The reference is in form:
> <filename>.<offset>.<length>
> The offset and length are implemented as int.
> Hence, it is not possible to read binary data which are stored after 2GB.
> The stack trace is like:
> Caused by: java.lang.NumberFormatException: For input string: "2147563021"
