主题: Re: 答复: No result from JDBC with Date filter in prepareStatement
Could you try the latest Kylin 2.1?
The Date parameter issue has been fixed during Kylin 2.0.

THank you for reporting. Could you check the kylin.log first?

大家好：
用kylin的JDBC查询，查询条件是date类型的，如果通过prepareStatement、setDate是查询不出数据的，然而直接用SQL可以查出数据
我用的是kylin版本：apache-kylin-1.6.0-cdh5.7-bin，jdbc版本：kylin-jdbc-1.6.0.jar，java版本：java
version "1.8.0_92"
代码1
Driver driver = (Driver)
Class.forName("org.apache.kylin.jdbc.Driver").newInstance();
Properties info = new Properties();
info.put("user", "xxx");
info.put("password", "xxx");
Connection conn = driver.connect("jdbc:kylin://xxx/learn_kylin", info);
PreparedStatement state = conn.prepareStatement(
"select " + "part_dt, sum(price) as total_selled,
count(distinct seller_id) as sellers "
+ "from kylin_sales where part_dt <= '2013-01-01' " +
"group by part_dt " + "order by part_dt limit 100");
ResultSet resultSet = state.executeQuery();
System.out.print("结果：");
while (resultSet.next()) {
System.out.print(resultSet.getString(1) + "\n");
}
运行结果
SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
