ORA-17270 When Inserting a LOB (Doc ID 1985465.1)

Last updated on AUGUST 09, 2023

Applies to:

JDBC - Version 11.2.0.4.0 and later
Information in this document applies to any platform.

Symptoms

On :  11.2.0.4.0 version, Thin JDBC driver, following upgrade from 10.2.0.4 driver connecting to 11.2.0.4 database,

ORA-17270 when inserting on a table with BLOB.

Updating the JDBC driver to 11.2.0.4 we get ORA-17270.

This error did not happen with older JDBC drivers.

In the following example table "mytable" contains 2 BLOB columns which are column5 and column6: 

org.springframework.jdbc.UncategorizedSQLException: Hibernate flushing: could not insert: [....]; uncategorized SQLException for SQL [insert into mytable (column1, column2, column3, column4, column5, column6, column7, column8, column9, column10, column11, column12, column13, column14, column15) values (?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?)]; SQL state [99999]; error code [17270]; Duplicate Stream Parameter: 6;

...

Changes

 The JDBC 11.2 implementation of this feature is substantially different from previous versions of JDBC.  Namely the OraclePreparedStatement.checkUserStreamForDuplicates did not exist in previous JDBC versions and seemingly allowed the duplicate streams to be used.
