Steven Hawkins updated TEIID-5121:
----------------------------------
Description:
If a source returns streaming lobs and a shared tuple source is used, then a streaming
exception can occur when the tuple source is reused.
For example in TEIID-5093 a union of two identical branches of the same texttable will
result in the exception:
TEIID60019 Streaming result has already been read once.
This issue was separated from the S3 issue as it affects any streaming lob, which would
typically be from the ws translator/resource adapter.

lookup('BQT1.SmallA', 'StringKey', 'IntKey', IntKey) AS StringKey,
DoubleNum FROM BQT1.SmallA
