當我使用卡桑德拉-jdbc我得到錯誤java.sql.SQLSyntaxErrorException惰性數據轉換成表:無法解析「ANI」作爲十六進制字節插入錯誤
連在localhost來測試集羣:9160。 [cqlsh 2.3.0 | Cassandra 1.2.0 | CQL規範3.0.0 |節儉協議19.35.0] 使用CQL3創建表
cqlsh:testkeyspace> create columnfamily login(
... key varchar primary key,
... name varchar,
... password varchar);
package com.bsmart;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
public class InsertCass {
public static void main(String[] args) {
try
{
Class.forName("org.apache.cassandra.cql.jdbc.CassandraDriver");
Connection con =DriverManager.getConnection("jdbc:cassandra://localhost:9160/testkeyspace");
String qry = "INSERT INTO login (KEY, name, password) VALUES ('t', 'ani','agrawal');";
PreparedStatement smt = con.prepareStatement(qry);
smt.execute();
// int i=smt.executeUpdate();
System.out.println("records inserted>>>>");
}
catch(Exception e)
{
System.out.println(" error: "+e.getMessage());
e.printStackTrace();
}
}
但ERROR-

log4j:WARN Please initialize the log4j system properly.

請幫助我。 謝謝
適當的版本不知道......似乎問題用U用來創建表的DDL語句。你必須正確指定驗證類和所有.. – 2013-02-22 12:03:15
