---------------------------------
Issue & fix info: [High Value Fix, Repro attached] (was: [High Value Fix])

> is deleted
> ----------------------------------------------------------------------------------------
>
> Key: DERBY-2992
> URL: https://issues.apache.org/jira/browse/DERBY-2992
> Project: Derby
> Issue Type: Bug
> Components: JDBC
> Affects Versions: 10.2.2.0, 10.3.1.4, 10.4.1.3
> Reporter: Kathey Marsden
> Attachments: TruncatedBlob.java
>
>
> If getBinaryStream is reading a value (READ_UNCOMMITTED) and the row is
> deleted by another connection, a truncated value will be returned without
> error. I believe instead either the whole value or an IOException should
> occur.
> With 10.2 and higher with the repro attahed we get:
> > java TruncatedBlob
> Embedded:
> Read 32669 bytes
> 0 rows in BLOBCLOB
> With 10.1
> Embedded:
> Read 40000 bytes (OK)
> 0 rows in BLOBCLOB
> Note network server returns the full value for both 10.1 and 10.2 but gives a
> lock timeout for 10.2+. I will file a separate issue for that.
