for field and record, you can use '0x' to specify hex character code,

常见几个例子：
根据查询语句导出:sqluldr2linux64.bin user=test/test@orcl query="select * from testdb" file="test.txt"
如果查询sql比较长，则可以把sql语句放入到文件中:sqluldr2linux64.bin user="username/pwd" sql="/home/query.sql" field="0x09" record=0x0a file="/home/table.txt" charset=UTF8
