indexedslicesQuery class error
I do the range query by the hector client when the state and birht_date columns are both indexed, it show the error:
The method addGtExpression(String,String) in the type IndexedSlicesQuery<String,String,String> is not applicable for the arguments(String,long)
The code is as below:
StringSerializer ss = StringSerializer.get();
IndexedSlicesQuery<String, String, String> indexedSlicesQuery = HFactory.createIndexedSlicesQuery(keyspace, ss, ss, ss);
indexedSlicesQuery.setColumnNames("full_name", "birth_date", "state");
indexedSlicesQuery.addGtExpression("birth_date", 1970L);
indexedSlicesQuery.addEqualsExpression("state", "UT");
indexedSlicesQuery.setColumnFamily("users");
indexedSlicesQuery.setStartKey("");
QueryResult<OrderedRows<String, String, String>> result = indexedSlicesQuery.execute();

Thanks .
I change ss to bytebufferserializer. It works fine.

addGtEqual???
You are still making the same mistake.
You are now saying that your values are going to be long (by passing LS as the valueSerializer), but in addEqualsExpression(), you are passing a String value.
2011/2/17 Raoyixuan (Shandy) <ra...@huawei.com>>
Not really.
I also tried the code as below:
StringSerializer ss = StringSerializer.get();
LongSerializer ls = LongSerializer.get();
IndexedSlicesQuery<String, String, Long> indexedSlicesQuery = HFactory.createIndexedSlicesQuery(keyspace, ss, ss, ls);
indexedSlicesQuery.setColumnNames("full_name", "birth_date", "state");
indexedSlicesQuery.addGtExpression("birth_date", 1970L);
indexedSlicesQuery.addEqualsExpression("state", "UT");
indexedSlicesQuery.setColumnFamily("users");
indexedSlicesQuery.setStartKey("");
QueryResult<OrderedRows<String, String, Long>> result = indexedSlicesQuery.execute();
It shows the error:

That's because in createIndexedSlicesQuery(), you have used SS as the valueSerializer, and then in addGtExpression("birth_date", 1970L), you pass a long as the value.

Re: indexedslicesQuery class error
Posted by Roshan Dawrani <ro...@gmail.com>.
3rd time same mistake...And it tells it all in the error message that it is
giving...
Now u r saying in createIndexedSlicesQuery(keyspace, ss, ss, ss) that ur
values are going to be String, but u r converting both values to
ByteBuffers.
As shown in
https://groups.google.com/group/hector-users/browse_thread/thread/520c5332dedfca4a,
pls pass the valueSerializer as BBS (ByteBufferSerializer)

That's because in createIndexedSlicesQuery(), you have used SS as the valueSerializer, and then in addGtExpression("birth_date", 1970L), you pass a long as the value.

I do the range query by the hector client when the state and birht_date columns are both indexed, it show the error:
The method addGtExpression(String,String) in the type IndexedSlicesQuery<String,String,String> is not applicable for the arguments(String,long)
The code is as below:
StringSerializer ss = StringSerializer.get();
IndexedSlicesQuery<String, String, String> indexedSlicesQuery = HFactory.createIndexedSlicesQuery(keyspace, ss, ss, ss);
indexedSlicesQuery.setColumnNames("full_name", "birth_date", "state");
indexedSlicesQuery.addGtExpression("birth_date", 1970L);
indexedSlicesQuery.addEqualsExpression("state", "UT");
indexedSlicesQuery.setColumnFamily("users");
indexedSlicesQuery.setStartKey("");
QueryResult<OrderedRows<String, String, String>> result = indexedSlicesQuery.execute();

addGtEqual???
You are still making the same mistake.
You are now saying that your values are going to be long (by passing LS as
the valueSerializer), but in *addEqualsExpression*(), you are passing a
String value.

Not really.
I also tried the code as below:
StringSerializer ss = StringSerializer.get();
LongSerializer ls = LongSerializer.get();
IndexedSlicesQuery<String, String, Long> indexedSlicesQuery = HFactory.createIndexedSlicesQuery(keyspace, ss, ss, ls);
indexedSlicesQuery.setColumnNames("full_name", "birth_date", "state");
indexedSlicesQuery.addGtExpression("birth_date", 1970L);
indexedSlicesQuery.addEqualsExpression("state", "UT");
indexedSlicesQuery.setColumnFamily("users");
indexedSlicesQuery.setStartKey("");
QueryResult<OrderedRows<String, String, Long>> result = indexedSlicesQuery.execute();
It shows the error:
The method addGtEqual<Epression(String,Long) in the type IndexedSlicesQuery<String,String,Long> is not applicable for the arguments(String,String)
