According to the example page of Astyanax:
https://github.com/Netflix/astyanax/wiki/Cql-and-cql3
When you run a COUNT
query, the result
returns a "number", so you can query that with:
try {
OperationResult<CqlResult<String, String>> result
= keyspace.prepareQuery(CF_STANDARD1)
.withCql("SELECT count(*) FROM Standard1 where KEY='A';")
.execute();
System.out.println("CQL Count: " + result.getResult().getNumber());
} catch (ConnectionException e) {
}
And it should give you the COUNT
result, but I am querying my table with cql3 and it isn't giving me a "Number", but "Rows", only one Row and only one Column.
The method hasNumber
gives False
and the method hasRows
gives True
, so now, How can I get the Result of my COUNT
query?
You should use
System.out.println("CQL Count: " + result.getResult().getRows().getRowByIndex(0).getColumns().getColumnByName("count").getLongValue());
