如何使用 LOAD CSV 查看 CSV 文件的列标题

如果有一个 CSV 文件，其内容如下所示

id,name,dob,addr1,addr2,city,state,country
1,Joe Smith,04/23/1971,121 Main Street,San Mateo,CA,USA
2,Bill Williams,09/21/2008,43 Overlook St,San Mateo,CA, USA

并且只想运行一个 LOAD CSV 命令来获取列标题，则以下命令就足够了

load csv with headers from 'file:///test.csv' as row with row limit 1 return keys(row);

这将返回类似于以下内容的输出

+---------------------------------------------------------------------+
| keys(row)                                                           |
+---------------------------------------------------------------------+
| ["country", "addr2", "city", "addr1", "dob", "name", "state", "id"] |
+---------------------------------------------------------------------+
