将数据存储备份中的数据加载到大查询中时，出现以下错误
When loading data from a datastore backup into big query I get the following error
错误:无效的字段名称"hq-country".字段必须仅包含字母，数字和下划线，以字母或下划线开头，并且最多为128个字符.
Errors:Invalid field name "hq-country". Fields must contain only letters, numbers, and underscores, start with a letter or underscore, and be at most 128 characters long.

推荐答案
请注意该错误消息，因为该错误消息已列出了允许的字母.
Pay attention to the error message, as it already lists the allowed letters.
并且连字符(-)标点符号不在列出的有效字母中.连字符是一个大问题，因为如果您最终将列名映射到变量，则大多数语言都不喜欢在变量名中包含连字符，因为它主要代表 minus/deduction .
And the hyphen (‐) punctuation mark is not among the listed valid letters. Hyphens are a big problem because if you end up mapping a column name to a variable, most languages do not like to have hyphens inside variable names, as it mostly stands for minus/deduction.
重命名该字段，使其仅包含字母，数字和下划线，以字母或下划线开头，并且最长为128个字符.
Rename the field, to contain only letters, numbers, and underscores, start with a letter or underscore, and be at most 128 characters long.
您可以使用例如: hq_country ，或者如果您有多个 hq 字段，则可以创建具有 hq 作为一个具有多个属性的 RECORD ，则它将为hq.country
You can use for example: hq_country, or if you have multiple hq fields, than you can create a schema that has hq as a RECORD with multiple properties and then it would be hq.country
