我获得了API结果并创建了此变量querystring。这个变量推送到循环数组，最后一个数组推送到bulkCreate但插入时失败。 bulkCreate可以使用哪种数据类型。
var queryString = col[0] + "," + col[1] + "," + col[2] + "," + col[3] + "," + col[4] + "," + col[5] + "," + col[6] + "," + col[7] + "," + col[8] + "," + col[9] + "," + col[10] + "," + col[11] + "," + col[12]+ "," + col[13]+","+col[15];
