1.2.5-23中masking功能里index不重复

[unknowissue]

描述
辛苦您对于masking功能的支持，现在有个小问题

在1.2.5-10中是

[{"index":0,"field":"id","type":"int","table":"users","schema":"db1","alias":"concat(id,phone)"},{"index":0,"field":"phone","type":"varchar(80)","table":"users","schema":"db1","alias":"concat(id,phone)"}] 

在1.2.5-23中是

 [{"index":0,"field":"id","type":"int","table":"users","schema":"db1","alias":"concat(id,phone)"},{"index":1,"field":"phone","type":"varchar(80)","table":"users","schema":"db1","alias":"concat(id,phone)"}]

看起来不符合我们的预期。。。
index: 列索引,标识为第几列,可能重复(如函数引用了多列时)

重现
模拟重现的步骤

#!/usr/bin/env python3
# -*- coding:utf-8 -*-
import pymysql
import prettytable as pt
tb = pt.PrettyTable()
sql = '''/*--user=xx;--password=xxxxx;--host=xx;--port=3308;--masking=1;*/
                          inception_magic_start;
                          use `db1`;
                          select concat(id,phone) from  users ;
                          inception_magic_commit;'''
conn = pymysql.connect(host='127.0.0.1', user='', passwd='',
                       db='', port=4000, charset="utf8mb4")
cur = conn.cursor()
ret = cur.execute(sql)
result = cur.fetchall()
print(result)
cur.close()
conn.close()
tb.field_names = [i[0] for i in cur.description]
for row in result:
    tb.add_row(row)
print(tb)
