in reply to Inserting a Long Raw into an Oracle table fails above 32512 bytes

See the section Handling BLOB / LONG / Memo Fields in the DBI docs
In this situation, the value of the $h->{LongReadLen} attribute is used to determine how much buffer space to allocate when fetching such fields. The $h->{LongTruncOk} attribute is used to determine how to behave if a fetched value can’t fit into the buffer.

    From the same document:

    The LongReadLen attribute only relates to fetching and reading long values; it is not involved in inserting or updating them.
