如何通过 LOAD CSV 查看 CSV 文件的列标题
如果有一个内容如下的 CSV 文件
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 命令来返回列标题，下面的示例即可满足需求
load csv with headers from 'file:///test.csv' as row with row limit 1 return keys(row);其返回的输出类似于
+---------------------------------------------------------------------+ | keys(row) | +---------------------------------------------------------------------+ | ["country", "addr2", "city", "addr1", "dob", "name", "state", "id"] | +---------------------------------------------------------------------+
