当我使用 copy-into 语法将 json 文件的数据装入 cnosdb 时,我发现我可以提供 dederimater 和 和 with_header 参数。 我认为这两个参数只应用于导入 csv 文件, 并且在其他文件格式中没有平均值。 对不对?
public ❯ copy into test from air file_format = (type = json , delimiter = @ , with_header = true);

我已经用 CnosDB-v2.4.1 尝试了您的 sql 语句, 但它回应错误, 以显示 < code> delater 和_header 字段是 CSV 所特有 :
public ❯ copy into test from air file_format = (type = json , delimiter = @ , with_header = true);
422 Unprocessable Entity, details: {"error_code":"010003","error_message":"Semantic error: delimiter and with_header fields are specific to CSV"}
