How to get current timestamp with CQL while using Command Line?

Question

I am trying to insert into my CQL table from the command line. I am able to insert everything. But I am wondering if I have a timestamp column, then how can I insert into ti

Answer 1

You can use the timeuuid functions now() and dateof() (or in later versions of Cassandra, toTimestamp()), e.g.,

INSERT INTO TEST (ID, NAME, VALUE, LAST_MODIFIED_DATE)
                  VALUES ('2', 'elephant',  'SOME_VALUE', dateof(now()));

The now function takes no arguments and generates a new unique timeuuid (at the time where the statement using it is executed). The dateOf function takes a timeuuid argument and extracts the embedded timestamp. (Taken from the CQL documentation on timeuuid functions).

Cassandra >= 2.2.0-rc2

dateof() was deprecated in Cassandra 2.2.0-rc2. For later versions you should replace its use with toTimestamp(), as follows:

INSERT INTO TEST (ID, NAME, VALUE, LAST_MODIFIED_DATE)
                  VALUES ('2', 'elephant',  'SOME_VALUE', toTimestamp(now()));
