Bryan Pendleton commented on DERBY-6923: ---------------------------------------- Assuming that this is in fact a strange behavior of Derby's locator implementation in the NetworkClient, DERBY-2496 is probably the relevant code to study. > Passing a ClientClob or ClientBlob from another connection to an INSERT > statement results in 'null' being written. > ------------------------------------------------------------------------------------------------------------------ > > Key: DERBY-6923 > URL: https://issues.apache.org/jira/browse/DERBY-6923 > Project: Derby > Issue Type: Bug > Components: Network Client, Network Server > Affects Versions: 10.13.1.1 > Environment: Java 8 > MacOS > Windows > Reporter: Gordon Innes > Priority: Critical > Attachments: DerbyEmbeddedOnly.java, DerbyNetworkOnly.java, > DerbyNetworkRead.java, DerbyNetworkWrite.java > > > When assigning a Blob or Clob from a ResultSet to a PreparedStatement > parameter on a second connection, null is written to the column instead. > Attached the same example using Embedded->Embedded, Embedded->Network, > Network->Embedded and Network->Network. > Only the Network->Network example exhibits the fault. > Originally discovered in HA-JDBC's sync code with 2 derby instances on > Windows. Example were tested using MacOS. Both were running on Oracle Java 8 > VMs. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
