-------------------------------------------
Summary: Allow empty blob literals in CQL3
Key: CASSANDRA-5452
URL: https://issues.apache.org/jira/browse/CASSANDRA-5452
Project: Cassandra
Issue Type: Bug
Affects Versions: 1.2.1
Reporter: Sylvain Lebresne
Assignee: Sylvain Lebresne
Priority: Minor
Fix For: 1.2.5
Attachments: 5452.txt
The current grammar don't allow empty blob literals (so '0x'). The goal here is
to allow the following syntax for that:
{noformat}
INSERT INTO test(k, b) VALUES (0, 0x)
{noformat}
I'll admit that '0x' is not the most beautiful syntax ever, but I think that's
the only thing that make sense.
I'll note that currently there is 2 workaround to insert empty blobs: you can
either use prepared statement (not a bad idea when using blobs anyway) or,
because we've deprecated but still support until 2.0 using strings as blob (to
allow upgrade from 1.2.0 to 1.2.1), you can use an empty string. I'll note that
this latter workaround will trigger a deprecation warning in the log however
and will stop working in 2.0.
