Key: CASSANDRA-2027
URL: https://issues.apache.org/jira/browse/CASSANDRA-2027
Project: Cassandra
Issue Type: Sub-task
Components: API
Affects Versions: 0.8
Reporter: Eric Evans
Assignee: Eric Evans
Priority: Minor
Fix For: 0.8
h3. String
Anything between double-quotes. Node-side this is just converted to bytes, so
it could really be used to represent *any* type so long as it is appropriately
encoded.
Examples:
{code:style=SQL}
SELECT "name" FROM cf;
UPDATE cf SET "name" = "value" WHERE KEY = "key";
{code}
h3. UTF-8
A double-quoted string literal that is prefixed with a "u" to indicated that it
should be encoded to bytes using the utf-8 charset node-side.
Examples:
{code:style=SQL}
SELECT u"name" FROM cf;
UPDATE cf SET u"name" = u"value" WHERE KEY = "key";
{code}
h3. Integer
An undecorated numeric literal, converted to a 4-byte int node-side.
Examples:
{code:style=SQL}
SELECT 10..100 FROM cf WHERE KEY = "key";
UPDATE cf SET 1000 = "thousand", 100 = "hundred" WHERE KEY = "key";
{code}
h3. Long
A numeric literal suffixed with an "L", converted to an 8-byte long node-side.
Examples:
{code:style=SQL}
SELECT 10L..100L FROM cf WHERE KEY = "key";
UPDATE cf SET 1000L = "thousand", 100L = "hundred" WHERE KEY = "key";
{code}
h3. UUID
A string-formatted UUID supplied as an "argument" to a ctor/function formated
string ({{uuid(<uuid string>)}}). Node-side this is converted back to the
corresponding UUID.
Examples:
{code:style=SQL}
SELECT uuid(5f989e95-ae07-4425-b84a-6876ba106c66) FROM cf WHERE KEY = "key";
UPDATE cf SET uuid(5621b93d-d3a2-4d22-8a59-bdb93202b6cb) = "username" WHERE
KEY = "key";
{code}
h3. TimeUUID (UUID Type 1)
A string-formatted time-based UUID (type 1) supplied as an "argument" to a
ctor/function formated string ({{timeuuid(<uuid string>)}}). Node-side this is
converted back to the corresponding UUID. In addition to a string-formatted
UUID, it should also be possible to supply dates in a variety of formats which
will result in a new UUID being created node-side.
Examples:
{code:style=SQL}
SELECT timeuuid(2011-01-01)..timeuuid(2010-01-21) FROM cf WHERE KEY = "key";
UPDATE cf SET timeuuid(now) = 1000L WHERE KEY = "key";
{code}
