CQL SELECT fails with prepareStatement

Question

In my sample app following snippet works fine.

SELECT_CQL = "SELECT * FROM " + STREAM_NAME_IN_CASSANDRA + " WHERE '" + CONTEXT_ID_COLUMN + "'=?";
Connection connection = getConnection();
statement = connection.prepareStatement(SELECT_CQL);
statement.setString(1, "123");
resultSet = statement.executeQuery();

But when I try to add another parameter to the where clause query returns nothing!!

SELECT_CQL = "SELECT * FROM " + STREAM_NAME_IN_CASSANDRA + " WHERE '" + CONTEXT_ID_COLUMN + "'=? AND '"+TIMESTAMP_COLUMN+"'=?";
Connection connection = getConnection();
statement = connection.prepareStatement(SELECT_CQL);
statement.setString(1, "123");
statement.setString(2, "1390996577514");
resultSet = statement.executeQuery();

When I try the exact query within cqlsh terminal, it works fine.

Answer 1

statement.setString(2, "1390996577514");

Double-check the datatype of your TIMESTAMP_COLUMN and make sure that it's a string. Otherwise you'll need to use the appropriate "set" method. Ex:

statement.setLong(2, 1390996577514L);
