Question

我正在尝试从mysql到csv文件执行2输出数据。我的代码如下：

public void exportData(Connection conn,String filename) {
        Statement stmt;
        String query;
        try {
            stmt = conn.createStatement();

            //For comma separated file
            query = "SELECT * into OUTFILE  '/tmp/input.csv' FIELDS TERMINATED BY ',' FROM router ";
            stmt.executeQuery(query);

        } catch(Exception e) {
            e.printStackTrace();
            stmt = null;
        }
    }
};

我在调用stmt.executequery的行中收到以下错误。

java.sql.SQLException: Access denied for user 'nxy'@'%' (using password: YES)
    at com.mysql.jdbc.SQLError.createSQLException(SQLError.java:1075)
    at com.mysql.jdbc.MysqlIO.checkErrorPacket(MysqlIO.java:3566)
    at com.mysql.jdbc.MysqlIO.checkErrorPacket(MysqlIO.java:3498)

    at com.mysql.jdbc.ConnectionImpl.execSQL(ConnectionImpl.java:2562)
    at com.mysql.jdbc.ConnectionImpl.execSQL(ConnectionImpl.java:2512)
    at com.mysql.jdbc.StatementImpl.executeQuery(StatementImpl.java:1476)
    at DBase.exportData(automateExport.java:50)
    at automateExport.main(automateExport.java:18)

我能够正确连接数据库甚至执行基本查询，但无法将数据导出到.csv文件。请帮忙。

谢谢

您需要为您的用户帐户设置FILE privilege，以允许通过SELECT .. INTO OUTFILE命令在服务器主机上创建文件。
