Question

如果重复这一点，我道歉，但我是机器人框架的总菜鸟，我需要帮助。我有两个数组，数据库的结果：

@{users}=   query   Select * from users
@{fieldNames}=   query  SELECT COLUMN_NAME FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_SCHEMA = 'robot_test' AND TABLE_NAME = 'users';

我从中得到的结果是：

@{users}= (1, 'user1', 'pass1', 'admin'), (2, 'user2', 'pass2', 'user')
@{fieldNames} = [ ('id',) | ('username',) | ('password',) | ('role',) ]

我想过滤@(fieldNames)成为

@{fieldNames} = [ 'id','username','password','role']

然后将其与@(users)混合以获取

@{mixedArray}=  (('id',1) , ('username','user1'), ('password','pass1'), ('role','admin')), (('id',2) , ('username','user2'), ('password','pass2'), ('role','user'))

有办法做到这一点吗？谢谢大家的帮助。

因为数据库库将查询结果作为元组列表返回，所以您可以遍历它们。我只做清理就是使用组合列表去除fieldNames列表中的元组。

从数组元素中删除特殊字符并将其与另一个数组混合
